Today we will learn a new and exciting excel formula – the all powerful SUMPRODUCT.

At the outset SUMPRODUCT formula may not seem like all that useful. But once you understand how excel works with lists (or arrays) of data, the SUMPRODUCT’s relevance becomes crystal clear.

### SUMPRODUCT formula – syntax and usage

The sum-product formula syntax is very simple. It takes 1 or more arrays of numbers and gets the sum of products of corresponding numbers.

The syntax is `=SUMPRODUCT (list 1, list 2 ...)`

So, for ex: if you have data like {2,3,4} in one list and {5,10,20} in another list, and if you apply SUMPRODUCT, you will get 120 (because 2*5 + 3*10 + 4*20 is 120).

At this point it might seem like an almost useless function. But all that will change in the next 2 minutes, keep reading.

### SUMPRODUCT and Arrays

Lets say you have a list of sales data with columns Name, Region, Product and Sales. Now, you want to know how many units the sales person named “Luke” sold. This is simple, you will write a SUMIF formula [examples] and use the Name column as “criteria range” and Sales column as “sum range”.

But, wait a second, you want to find how many units sales person “Luke” sold in the region “west”.

Hmm…. we have 2 options,

- Use an array formula
- Use a pivot table [what is a pivot table?]

Actually, there is a hidden third option, use SUMPRODUCT.

That is right, my friend, we can use SUMPRODUCT to do just this (and much more).

### Using SUMPRODUCT as an array formula

Assuming, the data is in range A1:D10, with Name in column A, Region in B, Product in C and Sales in D, the SUMPRODUCT formula is,

`=SUMPRODUCT(--(A1:A10="Luke Skywalker"),--(B1:B10="West"),D1:D10)`

Okay, lets take a minute and try to understand WTF (what the formula) is doing.

- The portion
`--(A1:A10="Luke Skywalker")`

is looking for Luke Skywalker across planetary systems in all universes 😉 It is going to give us a bunch of ONEs and ZEROs, one if the cell has Luke, Zero if the cell has something else. - The portion
`--(B1:B10="West")`

is doing the same, but gets 1s when the value is “West”. - The portion
`D1:D10`

is just returning all the sales figures. - When you put everything together and multiply, it just works.
That is your home work to figure out.**Why?**

Nice explanation Chandoo, I love it. It's "almost" crystal clear for me.

Can you explain the use of -- before the test ?

Hi Chandoo!

Your posts are really helpful, I have a querry, mentioned below.

Wanted to know whether sumproduct function can work with filters.

I have tried, however, the sumproduct values do not change as per list visible post filtering the column.

Thanks

Ahmed

In order to have filters affect SUMPRODUCT you must use SUBTOTAL function within SUMPRODUCT, it would go like =SUMPRODUCT(SUBTOTAL(3,A1:A10)*(A1:A10="Luke Skywalker")*(B1:B10="West")*(D1:D10))

Subtotal with option 3 here will return array of 1s and 0s (1 for unfiltered row, 0 when filtered out)

@Cyril .. good point. the double hyphen is converting a list of boolean (true, false) values to ZEROs and ONEs. Each hyphen acts as a negation. When you negate something, excel converts the underlying values to numbers and then reverses the SIGN. So TRUEs become -1s and FALSEs become 0s. The second negation reverses this and leaves just numbers thus allowing sumproduct to actually multiply instead of throwing an error.

Another alternative for this example is to use SUMIFS function, but it is available only in excel 2007 & 2010

This is more easier and logical than using sumproduct with double hyphen.

Nice post Chandoo!!

Is there any limit to the number of arguments we can use with SUMPRODUCT function?

Chandoo - good explanation. I'm still learning about sumproduct, arrays, and the function of -- .

I'd read elsewhere about using -- to "coerce" some values - I know what coerce means but I didn't really understand it in this context. I do understand your explanation though - basically it's multiplying the results by -1. I tried using - instead of --, and it appears to work just the same, as long as you have an even number of arrays to multiply, as you do in your Luke Skywalker, West example.

Hi all,

I've seen the double hyphen (--) in all SUMPRODUCT tips, but haven´t used and so far my formulas seem to work fine (no errors)... any idea when it should really be used?.

It converts the arrays' TRUE/FALSE arguments into boolean operators, i.e. 1/0.

Ones and Zeroes are much easier for programming purposes. If you click on the tick next to your formula in Excel, and you've got the same query/expression twice (once with and once without the double hyphen), you'll see if present something like this:

Without "--" - "{FALSE,FALSE,TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,TRUE}"

With "--" - "{0,0,1,0,1,1,1,0,0,0,0,1}"

It's a very handy action to use when counting cells. In SUMPRODUCT, it's a fantastic substitute for running COUNTA alternatives, when running across multiple spreadsheets.

Why can't i use 1 instead of "--". I think that is more easy to understand?

@Sanjot

I use 1* as it is easier to understand

You can also use 0+ or any other function that doesn't impact the output

Kaliman - for me, Chandoo's Luke Skywalker / West example doesn't work unless I use the double hyphen - -

I've just noticed in my earlier post, I had typed 2 hyphens and it came out looking just the same as 1. Apologies if anyone was confused by that 🙂

It should have read "...I tried using - instead of - - ..."

The double-negative on the TRUE/FALSE result is likely my favorite formula trick, and has always allowed me to stay away from arrays (which I find cumbersome and error-prone).

Chandoo/Excel Gurus, do you believe the SumProduct usage is inherently faster than an array of SumIFs? I've read Excel forum threads that assert that the SumProduct performance difference is negligible because Excel was performing array activities behind the scenes, but those threads were a bit old (circa 2002/2003), and I never really bought into it. What has your experience been on the performance question?

Great post. The array part of this post will come in extremely handy at work.

sumproduct() is my favourite multiple condition summing formula. but double"-" before the argument was a new thing for me as I usually used syntax like this =sumproduct((array1="luke")*(array2="west")*array3)

however, sumproduct has one drawback - the array you want to sum must consist only from numericals. even if actual selections wont include cell like "n.a." (might happen in datasets), sumproduct() will result in an error. find/replace helps just fine 😉

Seconding the use of SUMIFS if you have 2007 or higher. I personally find it much more intuitive.

Hi Brian, Hi Shandoo,

for more details and considerations ...

here from an Excel Guru :

http://www.xldynamic.com/source/xld.SUMPRODUCT.html

;o)))

Great explanation Cahndoo,

I have seen the -- used often in the SUMPRODUCT formula but not the N() fucntion, is there a reason not to use the N() function?

Social comments and analytics for this post...This post was mentioned on Twitter by r1c1: Checkout What is Excel SUMPRODUCT formula and how to use it? http://bit.ly/1EbIsU...

Excel has trouble doing math with text values. It needs to turn them into numbers first.

Type '0 into a cell (mind the quote). This makes a text zero.

Type =A1=0 into another cell, and you will get FALSE as the result.

Type =A1-1 into another cell, and you will get -1

But wait, if it's not a number, why can it do math?!

Well, Excel forces things to be numbers when you do math on them.

So if you use math in sumproduct, you don't need the double-minus:

=SUMPRODUCT((A1:A10="Luke Skywalker")*B1:B10="West")*D1:D10)

When it does the math for this, it will multiply all the zeroes and 1's and values together, and will always come out with a number.

If you don't put them in:

=SUMPRODUCT((A1:A10="Luke Skywalker"),(B1:B10="West"),D1:D10)

You get 0 instead.

So we need to turn them into numbers first. We can do that a lot of ways. For instance:

=SUMPRODUCT((A1:A10="Luke Skywalker")+0,(B1:B10="West")+0,D1:D10)

=SUMPRODUCT((A1:A10="Luke Skywalker")*1,(B1:B10="West")*1,D1:D10)

=SUMPRODUCT(N(A1:A10="Luke Skywalker"),N(B1:B10="West"),D1:D10)

But when it comes down to it, the people who are really smart at Excel figured out that Excel is fastest when it uses the unary operator (the '-' sign) twice.

So now people write:

=SUMPRODUCT(--(A1:A10="Luke Skywalker"),--(B1:B10="West"),D1:D10)

Feel free, if you have trouble, to use the *1 or +0 or N() if you'd prefer. They will work too.

So, to conclude.

If you use SUMPRODUCT with commas, you need to turn true/false values into numbers first by doing math or by using the N() function.

If you use SUMPRODUCT with multiplication, you're already doing math so you don't need it.

Most of the time it's personal preference (I'm sure that there is a difference in speed in the long run, but most of us will probably never ever know about it).

Thank you Sal Paradise, Good Post

well explained, thank you Sal 🙂

Really Superb Explanation. Very easy to understand. Thanks Sal Paradise.

Hello Chandoo

-- makes formula confusing for many users and it can be avoided if you replace , with * . The revised formula will be as under

=SUMPRODUCT((A1:A10="Luke Skywalker")*(B1:B10="West")*(D1:D10))

This formula is giving multiconditional sum and we have used only two conditions. However you can add as many conditions as you like provided the hight of each range is same.

If you remove the last entry with does not have condition attached to it, the formula will do the multiconditional count.

Formula for multiconditional count will be

=SUMPRODUCT((A1:A10="Luke Skywalker")*(B1:B10="West"))

Thanks

Using the * will work for "and" criteria but you may not always want to use "and" in your formulas. To use "or" criteria you can use a + sign which is also doing math so you would not need to the the --.

Does this usage of SUMPRODUCT allow for multiple entries of the search criteria throughout a range?

i've always been fond of the SUMPRODUCT((range=criteria)*(range=criteria)) to search for multiple variables: Saves on pesky pivot tables.

@Moatasem & Brian & Andy

Yes, we can use SUMIFS in the same way. It is a better function, but not backward compatible with earlier versions of excel. That is why I wrote about this first. I will write about SUMIFS , AVERAGEIFS and COUNTIFS in an upcoming article.

@Rakesh...

You are welcome. Yes, There are limitations on SUMPRODUCT - It takes up to 255 arrays. It also slows down considerably once you have too many rows in the arrays (lists). I suggest using pivot tables or manual calculation mode if that happens.

In general, SUMPRODUCTs hold up well even for fairly large data (like few hundreds of rows or even thousands).

@Gerald

it is better to use double hyphen (minus sign) before every array as it lets you add / remove arrays with out worrying about the even-ness of the number of attributes.

@Brian S

"Chandoo/Excel Gurus, do you believe the SumProduct usage is inherently faster than an array of SumIFs? ..."

I have not benchmarked SUMPRODUCT against other similar formulas like VLOOKUP, MATCH or Array SUM() formulas. But I have experienced considerable slow down when I have few thousand rows of data, no matter what formula is used. If I am writing the code behind these formulas, I would have used similar logic for all. So I dont see a reason why one formula should be faster / better than other. But I am as intelligent as a cabbage when I am talking about these things.. so...

Here is a request to all.. "if you have benchmarked these formulas, please let us know the results thru comments"

@Modeste ... Thanks for the excellent link.

@Kanti Chiba

You can use N() in the same way. N() formula converts the input to number.

@Sal .. awesome explanation. Donut for you.

@Yogesh .. Again, super trick. I agree with * approach. Donut for you as well.

@Simon

You can use Array concepts like + operator to check for multiple conditions. For eg. ((A1:A10=”Luke Skywalker”)+(A1:A10=”Hansolo”)) should check for both Luke and Hansolo in the range A1:A10.

If you use a + sign then it reads as "or". So what you are really saying is sum values for Luke Skywalker OR Hansolo. This is an important distinction! Using a * is read as "AND".

Chandoo my man. I had to multiply some arrays today, and was momentarily scratching my head trying to remember how to do this with array formulas. I took a break, checked out your RSS feed, and whoa...you've taken my question right out of my mind and answered it.

I owe you a donut for this, which cancels out the one I earnt the other day. Don't you just love this weightless, low calorie economy?

@Jeff, in the donut economy things never cancel out. They just get added up, because donuts are absolute(ly delicious).

I seriously wonder how many people-hours you saved with this one post alone Chandoo.

I guess it leaves more time for virtual donuts. 🙂

@Eric.. that is so sweet (and not in the heart killing donut sweet way). Thank you 🙂

[...] used SUMPRODUCT liberally to summarize the gift data to show us “how many people got the gifts”, [...]

I have a sumproduct question!

In my workbook i am working with 2 worksheets: "Hours" & "Variance".

I am essential developing a variance tool on the variance tab.

I have a list of employees on the hours tab and the rests of the actual hours that they have worked by dated column.

I am trying to write a formula that totals all of the hours for a single employee based on a given date. See example at the end.

These formulas work as a stand alones:

=ADDRESS(MATCH(A10,Hours!$M$621:$M$725,0)+ROWS(Hours!$L$1:$L$620),MATCH($C$2,Hours!$620:$620),4,1,"Hours")

=SUMPRODUCT(--(Hours!M621:M725=A10)*Hours!$N$621:$BZ$725)

BUT, when I try to combine the two to get the date variability like I want, Excel says my formula contains an error. Here is what the formula looks like:

=SUMPRODUCT(--(Hours!M621:M725=A10)*Hours!$N$621:ADDRESS(MATCH(A10,Hours!$M$621:$M$725,0)+ROWS(Hours!$L$1:$L$620),MATCH($C$2,Hours!$620:$620),4,1,"Hours"))

Doughnuts all around for anyone who can help me on this one! I suspect that I have a syntax issue in my formula but not sure.

Example:

Variance Tab

As of: 11/28/2009

Resource Total hours worked Answer should be

Billy 130

Bob Formula 50

Joe goes 80

An here 90

Jill 160

Hours Tab

Resource 11/14/2009 11/28/2009 12/12/2009

Billy 40 90 30

Bob 30 20 80

Joe 50 30 80

An 80 10 40

Jill 80 80 50

bummer, example data formatted ugly....imagine rows and columns, rows and columns

@Jadam... I think this is happening because you cannot define a range like a1:Address(xxx), it has to complete range or complete indirect. Why dont you use INDIRECT("Hours!$N$621:"&ADDRESS(...)) in the sumproduct.

Also make sure the INDIRECT is wrapped in ()s to avoid any confusion.

Hi Chandoo, Hi Jadam

;o))) there is no use of SUMPRODUCT ....

just you have to name some ranges

ResDat =Hours!$B$1:$A$Z1 ( ie for 52 dates)

ResNam =Hours !$A$2:$A$1000 ( ie for 1000 names)

in Variance!B2 put this formula

=SUMIF(WBK1!resDat,"<="&$A$10,INDIRECT("hours!"&ADDRESS(1+MATCH(A2,WBK1!resNam,0),2)&":"&ADDRESS(1+MATCH(A2,WBK1!resNam,0),52)))

and pull it down as many time as ressource names

beware :

dateref of calculation is absolute $A$10

current ressource name is relative : A2

WBK1 is actual Workbook.name

HTH

;o)))

Supposedly -- is slightly faster than any other way of converting the logicals to numbers.

My preference is to use =SUMPRODUCT(1*(A1:A10... instead of =SUMPRODUCT(--(A1:A10=

As it is easier to read, especially for those not so familiar with formulas.

I like your idea.

Just fallen on this site - already hooked.

Sumproduct is great. I used to struggle to add multipple criteria up in my spreadsheets, and then someone from UtterAccess.com taught me about Sumproduct. I can't thank that person enough.

Anyway...many articles to catch up on. Keep up the outstanding work.

Chandoo:

The SUMPRODUCT function is the most versatile in Excel.

It can be used to do multicolumn sorts by array (with no human intervention or VBA required).

It can determine if a number is prime.

It can coerce bitwise operations in integers (i.e. bitwise logical AND, OR, XOR, IMP, EQ, and NOT).

It can be used to supercharge lookup tables with bitmasks.

It can find the dot product of two vectors.

It can do the database calculations you addressed in this post and has the massive advantage over SUMIF and COUNTIF (and the Excel 2007 SUMIFS and COUTNIFS) that it can handle OR clauses in the criteria.

It can replace most any Array-Entered Formula that uses SUM, and is usually about 10% faster.

This list could go on for pages...

Hi Chandoo,

I have a comment for Brian...

I have heard about the performance issues of SUMPRODUCT.

I made a test on a 1 million rows table using SUMIFS and SUMPRODUCT side by side and didn't notice any significant differences in calculation time.

In my lists there are a lot of =NA() Values. Therefore Sumproduct returns NA aswell, is there any workaround besides converting to empty cells?

@Chris.. you can use SUM () formula with arrays, like this:

=SUM(IF(ISNA(F14:F20),"",F14:F20)) to check for NAs and replace them with empty spaces or zeros. You must ctrl+shift+enter that formula to get it work.

Thx Chandoo!

Hi Chandoo,

Came across your site when looking for help on sumproduct.

Firstly, what does the "--" do in this formula?

secondly, can I use Named Range in replace of "D1:D10"; giving your formula to change from:-

"=SUMPRODUCT(--(A1:A10="Luke Skywalker"),--(B1:B10="West"),D1:D10)"

to

"=SUMPRODUCT(--(A1:A10="Luke Skywalker"),--(B1:B10="West"),SALES)"

Thanks in advance.

Cheers,

CL

@CL

The two - - 's or double nagatives and aren't required in your case, although it is good practice to use them all the time just in case.

Sumproduct takes each set of (Range=something ) and converts each element in that range to a True/False.

In your case you have 2 sets of (Range=something) and so when they are multiplied the result is converted True = 1 & False =0.

If you only have 1 set of (Range=something) then you need to do some maths to that to convert the True/Falses to values for evaluation. Hence the use of - -.

I prefer to use 1* as I think it reads easier and other do 0+, but all do the same thing they convert the True/False values in the array to 1's and 0's for subsequent use.

It s good practice to use a - - or 1* as if someone else comes along and removes one set of (Range=something) then the remaining equartion without a - - wont work.

Absolutely use Named Ranges, They will make your formulas so much easier to read and understand in 6 months when your trying to work out "What did I do here ?"

Have a look at http://chandoo.org/wp/2009/11/10/excel-sumproduct-formula/

[...] Sumproduct: http://chandoo.org/wp/2009/11/10/excel-sumproduct-formula/ [...]

It works fine but I think it is prone to very popular mistake - spaces. Name "Luke Skywalker" can be written as "Luke Skywalker " - this is very common mistake I deal with. Often people that are filling such sell-results-datasheets use copy-paste method (and copy too much). In the spreadsheet it looks the same:

Luke Skywalker

Luke Skywalker

If the the table is large - few hundreds of records, it will be very difficult to find that there is mistake (e.g. one record with sales = 36, and total sum of Luke S. = 12 340, the potential accountant will not notice that - 36 too small comparing with 12 340, and he assumes that is OK).

So I propose to slightly modify the formula. Instead of:

=SUMPRODUCT((A2:A21="Luke Skywalker")*(B2:B21="West"),C2:C21)

use:

=SUMPRODUCT((TRIM(A2:A21)="Luke Skywalker")*(TRIM(B2:B21)="West"),C2:C21)

There is also "Trim" with the region (West), just in case :). Of course it is possible to use some data validation when filling the spreadsheet, and then there will be no need for Trim.

pfabi: use TRIM(). It removes all unnecessary spaces (eg anything except for one space between words).

Hey Chandoo,

The data is not coming through properly here - as the blank rows are not being put in.... There are a couple of blank rows through out the columns - could that be causing the issue?

@Lorna.. I tried with some dummy data and it seems to work fine. Are you sure the numbers are numbers and not text looking like numbers?

I ask this because you have some numbers with thousands separator & 2 decimal points and some without them (the 400 in middle).

@Chandoo

I think that may be exactly it, my problem is that the data comes off a webquery - which needs to be refreshed from a database and the values need to be calculated etc etc, so changing the format each time defeats the purpose.

Absolutely any idea how I can circumvent this?

: (

@Lorna

Multiply all your data by 1 using paste Special Multiply

That will fix it.

@Hui,

Thanks for the info - my problem is that the data comes through a webquery - so any changes are lost with a refresh - so I need to find a solution in the actual formula : (

Dunno if there is anything that can help?

I would be more than happy to sent the spreadsheet to anyone that is interested..........

Hi Lorna,

I use data that is exported from a webpage and find that some data does not work with sumproduct until I clean it by running the Trimall macro from http://dmcritchie.mvps.org/excel/join.htm#trimall. Not sure if it will help but worth a try 🙂

If your data is formatted as text and looks like a number you can use VALUE(). eg VALUE("1,000.00") will return the number 1000

What is the need for hte "--" in the sumproduct formula?

Also, having trouble getting an answer..I am getting an error. Please help.

@Ash... the the - (minus symbol) forces boolean values (TRUE, FALSE) to be converted to numbers. But since it is minus, it will negate them. So we use one more - sign (thus double minus) to convert TRUE to 1 and FALSE to 0.

What error are you getting?

@chandoo

can u give example work sheet of above example

@chandoo and hui

i have criteria in E coloum and have value data in H and S column

problem is whenever i m using sumproduct formula to get H column data it shows true result

but when i apply it for S column data it show the #VALUE error

i have checked it from all side but cant get sucess

nd if i apply sumif formula then there is no issue

@Rahul

Check the following

1. The range length in Columns E, H and S must be the same, eg: E2:E20, H2:H20 and S2:S20

2. In Columns H & S check that the cells don't contain a leading or trailing space

3. If Column S is numbers, but not as a Formula, type 1 in a blank cell, copy it and Paste Special Multiply over the range in Column S, this will convert text that looks like numbers to numbers.

If the above doesn't help, can you post the two formulas and some data to show us what you have

@hui

thanx alot

in my situation S column contained formula and after applying your third suggestion its working perfectly

but there is any formula which can show result of contained of formula column

i have try text formula as follows but showing errror

=SUMPRODUCT((E2:E20="tikka")*(TEXT(H2:H20,"0")))

i am asking this because my data expand every hour and have to see result all time but doing this "copy paste and multiply always" is not convenient

@Rahul

Try:

=SUMPRODUCT(1*(E2:E20=”tikka”),(H2:H20))

or

=SUMPRODUCT(1*(E2:E20=”tikka”),(S2:S20))

@hui

above formula

is showing same error #VALUE

Sumproduct is a Numerical Function that can return a number or True/False

Can you explain your application?

due to my long conditions excel has already prompted me that I have a long formula... is there anyway I can get around? I only have one condition left

Can you please help me out with changing this formula to =SUMPRODUCT?

I currently have this formula;

=SUMIF([Test.xlsx]Sheet1!$C$2:$C$101792,A14,[Test.xlsx]Sheet1!$F$2:$F$101792)

I have tried using this;

=SUMPRODUCT(--([Test.xlsx]Sheet1!$C$2:$C$101792=A11),[Test.xlsx]Sheet1!$F$2:$F$101792) but it returns an a value of '0'.

Can you help me by telling me where my formula is wrong?

@Greg

Try:

`=SUMPRODUCT(([Test.xlsx]Sheet1!$C$2:$C$101792=A11)*[Test.xlsx]Sheet1!$F$2:$F$101792)`

Can someone help me with the following calculation? what is the formula? Example. Cell A1 (250) is greater then Cell A2 (150), the result in cell A3 will be 100, but if the Cell A1 is not greater then Cell A2, so the result must be in Cell A3 0 (zero). This is the point. Please help me. email: zafar_fafa@yahoo.co.uk

Zafar:

=IF(A1 > A2,100,0)

or you could do this:

=(A1>A2)*100

...because the (A1>A2) bit returns 1 if true, or zero if false, which you then multiply by 100. So if true, 1 * 100 = 100. If not true, 0 * 100 = 0

I was looking for a work around for SUMIFS function to work on gDocs SpreadSheets.

Unfortunately, SUMIFS is not available in gDocs, so I used the sumProduct function instead.

In my example, I had ranges to work with

Column A was minimum value of a range

Column B was maximum value of range

Column C was number of occurrences within the given Min and Max

i wanted to summarize the data with new and more meaningful ranges.

So, in column E, I defined the new Minimum Range

in Column F i defined the new corresponding Maximum Range

in Column G, i applied the following formula

=SUMPRODUCT((COLUMN1>=E2)*(COLUMN2<=F2)*(COLUMN3))

It does not take full advantage of SUMPRODUCT, but it is a handy workaround for SUMIFS in gDocs and older versions of Excel which dont support SUMIFS.

A very thorough explanation of SUMPRODUCT that I have found to be extremely helpful is at

http://www.xldynamic.com/source/xld.SUMPRODUCT.html

I first discovered the xldynamic website when researching SUMPRODUCT on various MVP websites ... there is a link on this page

http://blog.contextures.com/archives/2009/06/17/excel-for-underdogs/

HTH!

Hi clif

in fact the above link was already here for a long time :

http://chandoo.org/wp/2009/11/10/excel-sumproduct-formula/#comment-84704

;o)))

So I have two problems with this.

First I have data which is telling me whether or not a delivery was made on the correct delivery day (returning a Y or N), what month it was delivered in (Returning Jan, Feb, Mar) and the rate that was charged. The sumproduct is happily counting how many were not delivered on the right day in each month:

=SUMPRODUCT((a:a="n")*(b:b="jan"))

However when I try to expand to total the rates for the month I get an value error.

=SUMPRODUCT((a:a="n")*(b:b="jan")*(C1:C300))

Any ideas?

My next issue is that I need to do the same sums but for week numbers. I am assuming that my problem here is that you can't have text and a number in the same formula.

ie =SUMPRODUCT((a:a="n")*(b:b="1"))

I've tried using the - - to turn the text into 1's like you say, but it is not having any of it.....

Help??

for your problem 1:

=SUMIFS(C:C,A:A,"n",B:B,"jan")

this will calculate the sum of all values in column C where

Column A contains "n"

and Column B contains "jan"

for problem 2, i would suggest you create another column for week number

if that does not work, do drop in some more details of what the data looks like

Hi FSJ,

Thanks for the swift response.

Alas I am having the same issue as a lot of you, in that I did SUMIFS, sent to a colleague who was still running 2003, hence the need for something else! While sending her just the values answers her questions, I would like to master SUMPRODUCT as this is the first opportunity I have had to use it!

My bad, the week numbers are in a different column. Sorry I didn't make that clear. It is difficult to explain these type of problems clearly....

Does that help? Thanks

=SUMPRODUCT((A:A="n")*(B:B="jan"),C:C)

this would return the same result as SUMIFS formula

regarding the week grouping, say

column A contains Y/n

column B contains Month

Column C contains the amounts

Column D contains the week number

=SUMPRODUCT((A:A="y")*(B:B="jan")*(D:D=1),C:C)

this would extend the formula to cater for the week number given in column D.

i usually use the sumproduct formula in the following way

=sumproduct( (contidion 1) * (condition 2) * ... * (condition n) , (result array) )

i.e., the conditions are multiplied and the comma comes before the resultant column(s)

in your case, the revenue/amount column was the resultant

month name, week number, delivery state (y/n) were your conditions

but sumproduct is a lot more powerful than just the above stated usage

Hi FSJ,

I appreciate youR time on this. I know how powerful excel is and have already learned loads just from visiting this site!

I have fixed the first problem. I had to change the rate column format to "general" then it picked it up.

But the second problem still confuses me as it is not even counting up :O(

So, to clarify:

Column C contains (Y/N)

Column E contains Week Number (1,2,3)

Column P Rates

Cells all currently formatted to "General"

=SUMPRODUCT((Data!$C:$C="N")*(Data!$E:$E="1")) is coming back with a 0. That's before I even try to expand to the rates column?

Try removing the quotation marks around the 1

=SUMPRODUCT((Data!$C:$C=”N”)*(Data!$E:$E=1))

that should be a start

also, i am assuming that you want to sum the Ns and not the Ys in column C

Hi FSJ,

I couldn't reply to your reply.

Just to say that cracked it, thank you for putting up with me. I owe you a coffee!

Thanks a million for the clear ordinary language explanation of sumproduct.

Yesterday I was stumped trying to match four criteria and return a number.

This morning I thought, "sumproduct should work. I need to find a sumproduct tutorial."

I created the formula and then solved my own question on excelforum.com.

I am pleased! 😀

Is it possible for sumproduct to return text? Using the sample data that began this thread I used the following array formula...

=SUMPRODUCT(($C$2:$C$21=$I$1),--($B$2:$B$21=$H$1),--$A$2:$A$21)

Unfortunately, this formula continues to give me a #value! error.

To be more clear with my formula (the previous one contained references) here is the revised formula...

=SUMPRODUCT(($C$2:$C$21=116),--($B$2:$B$21="West"),--$A$2:$A$21)

Me again!

Trying to use this on a new report and it keeps returning a #NUM or #N/A error. What am I doing wrong? I just want to count how many BA's have got a N for example.

Column AL has list of depot codes ie BA, BG, BL...

Column AP has Y/N responses in it.

=SUMPRODUCT(('Orders Extract Data'!$AL$3:$AL$21384="BA")*('Orders Extract Data'!$AP$3:$AP$3519="N"))

Any Ideas?

K

@K

Your ranges need to be the same length

eg:

`=SUMPRODUCT(('Orders Extract Data'!$AL$3:$AL$21384="BA")*('Orders Extract Data'!$AP$3:$AP$21384="N"))`

or

`=SUMPRODUCT(('Orders Extract Data'!$AL$3:$AL$3519="BA")*('Orders Extract Data'!$AP$3:$AP$3519="N"))`

The answer to my question may lie in the 100+ replies to this post- I printed them out and will read through them as I await your response - but my particular question is whether SUMIF and SUMPRODUCT can be use d in the same formula. I want to be able to do a SUMPRODUCT only if certain criteria are met in another column (or columns) within the spreadsheet. Is that possible? I'm trying to avoid adding columns to do an intermediate calculation as it would be an extremely tedious task at this point. THANKS!

You can ignore this post - figured it out after reading through that SUMPRODUCT "does it all". Not sure I understand the need for the double minus sign, however - seems to work fine without it.

Handy info here, Thanks a lot to all for sharing their expertise.

I am stuck getting a sum of values based upon certain month. i.e.

Column A got Expense dates (e.g., 20-May-12, 01-Jun-12, 04-Jun-012 etc)

Column B got nature of expense (e.g., Business, Personal, etc)

Column C got amount.

I wanted to put all expenses under business head which occurs in the month of Jun in a particular cell. I am using following formula but without any luck. Any suggestion what i am doing wrong.

SUMPRODUCT(--(MONTH(E_Date)=6),--(Charged_To="Company"),Amount)

or

SUMPRODUCT(--(MONTH(A1:A10)=6),--(B1:B10="Company"),C1:C10)

Thanks

you can try the following formula

Column A contains dates

Column B contains nature of expense

Column C contains amounts

SUMPRODUCT((MONTH($A$2:$A$76)=6)*($B$2:$B$76="Business")*($C$2:$C$76))

i have limited the data to 76 rows... you can change that value or try any other range (as long as all the ranges are the same)

Thanks FSJ,

It didn't help, giving error "#Name?".

SUMPRODUCT((MONTH($A$2:$A$76)=D2)*($B$2:$B$76=D5)*($C$2:$C$76))

D2 = 6

D5 = Business

if this does not help, try putting in

arrayformula(SUMPRODUCT((MONTH($A$2:$A$76)=D2)*($B$2:$B$76=D5)*($C$2:$C$76)) )

Thanks a Lot FSJ, Was out of town for some time, so couldn't check it earlier.

Got it working now. However still unable to understand why we need to multiply each criteria. Shouldn't sum product be doing this automatically?

Very neatly explained.

Thanks!

Once again I reference this page and learn more.

Hopefully one day I will be able to contribute and earn a donut!

Thanks, folks.

Here's one for you all... I have the following formula, already working in Excel 2010; BUT I need to 'downgrade' it to be compatible in 2003 (yes, s/w nine years old! hey-ho).

=AVERAGEIFS(Data!S:S,Data!L:L,"Atherstone",Data!T:T,"Service",Data!C:C,">="&K3,Data!C:C,"<="&K4)

K3 is the start of a date range and K4 is the end.

I've been told that SUMPRODUCT is the answer to all my woes, but I can't for the life of me work it out. I know this a bit of a "do my homework for me?" question, but this is one of

only140 cells I need to convert (upgrading is off the table), so if someone fixes this for me, they can have my first-born (no, really - she's a menace!).Think of it as a 'challenge', if that helps. Me, I'm on my third Martini already...

@KevinA

Try:

`=SUMPRODUCT(Data!S:S* (Data!L:L="Atherstone")* (Data!T:T="Service")* (Data!C:C>=K3)* (Data!C:C<=K4)) / SUMPRODUCT((Data!L:L="Atherstone")* (Data!T:T="Service")* (Data!C:C>=K3)* (Data!C:C<=K4))`

=AVERAGEIFS(B1:B14,A1:A14,C1)

=SUMPRODUCT( (A1:A14=C1)*B1:B14)/COUNTIF(A1:A14,C1)

same result

see if you can extend it to fit your needs.

I don't get the syntax of the double "--" in this formula..

`(--(A1:A10="Luke Skywalker"),--(B1:B10="West")`

`What are the "--"'s in front of (A1:A10) and (B1:B10) needed for?`

@Mike together double unwary serves to convert the arrays of True/False to an array of 1/0's

it could have been done as

`((A1:A10="Luke Skywalker")*(B1:B10="West")`

`Noting that multiplying the array by each other does the same thing`

Dear List,

I do need urgent help about SUMPRODUCT formula. My excel table has 2 numeric rows and 1 text row showing criteria. I want to multiply these numeric rows, according to the criteria row. The following formula didn't work:

I tried with comma instead of *

May I request your help please.

Thank you very much.

Zeynep

Zeynep

Your formula should work ok

So maybe check that your data doesn't have any text values in the Numeric Rows or error messages in any of the rows

Also check that calculation is set to Automatic

If this doesn't help, can you copy/paste say A1:J3 here so we can see some data

Hui

I checked, there is no text in the cells except criteria row. My sample data,

A B C D E F G H I J K L..... CA CB

I have tried using your formula in different forms but it doesn't seem to be working, can anyone help me out?

I have this in my cell:

=SUMPRODUCT(--(Sheet1!$F$3:$F$19=Sheet2!B11),Sheet1!$I$3:$I$19)

the first list is an array of months in the exact same format as Sheet2!B11, I've even done a cell to cell check to make sure it comes back as 1 which it does. The second list is numbers which need to be added.

Want to add up total expenses for each month, but for some reason it just keeps coming back $0 when it should be $525. Any help would be much appreciated. Thx.

Nevermind. got it! Needed to put the MONTH in there to compare apples to apples. Final equation is this:

=SUMPRODUCT(--(MONTH(Sheet1!$F$3:$F$19)=MONTH(Sheet2!B11)),Sheet1!$I$3:$I$19)

Thanks again

As my best practice, I always segregate each array with closed parenthesis () and put a space between each array to avoid confusion and better readability.

=SUMPRODUCT( (MONTH(Sheet1!$F$3:$F$19)=MONTH(Sheet2!B11)) * (Sheet1!$I$3:$I$19) )

Likewise, I find the use of named array very helpful especially for variable source. So if you create a named variable range as below:

Date = OFFSET(Sheet1!$I$3,0,0,COUNTA(Sheet1!F:F)-1,1)

Amount = OFFSET(Sheet1!$F$3,0,0,COUNTA(Sheet1!F:F)-1,1)

Note that I use COUNTA(Sheet1!F:F)-1 for both so that height are equal for all array in the sumproduct formula.

Below will arrive at same result as above.

=SUMPRODUCT( (MONTH(Date)=MONTH(Sheet2!B11)) * (Amount) )

Try adding records after Sheet1!F19

Hi NickE,

One of the main reasons for slow response on sum-product (in my case) and performance issues of excel itself is when i set the entire column as data rather than just the required range.

something like A1:A155 rather that A:A *might* be the solution. it worked for me.

Dear Chandoo

Very useful tip.

We cam also use the DSUM formula i guess. to find out the lookup of sevral conditions and sum based on conditions, the formula is helpful for ddesigning dashboards

Ok maybe this is well known but I've decided to leave it here as I use it in a daily basis.

The sumproduct + responsive named ranges is one the most powerful tools in Excel.

The sumproduct is really well explained by Chandoo here so I will just talk about the responsive named ranges.

For example you want to build a resume table form a constantly growing set of data (both horizontally and vertically), where the first column has repeating identifiers that you use for your calculations and the first row has all the attributes you have from those identifiers set these 3 named ranges:

identifiers

=OFFSET(Sheet1!$A$2,0,0,COUNTA(Sheet1!$A$2:$A$900000))

attributes

=OFFSET(Sheet1!$B$1,0,0,1,COUNTA(Sheet1!$B$1:$ZZ$1))

data

=OFFSET(Sheet1!$B$2,0,0,COUNTA(Sheet1!$B$2:$B$900000),COUNTA(Sheet1!$B$2:$ZZ$2))

Then simple sumproduct it to fill your resume table with (considering column A has the identifiers and row 1 the attributes you want to pull)

=sumproduct((identifiers=$a2)*(attributes=b$1),data)

Then just copy it on all the cells you want filled.

Hope it helps

Thank you for this tutorial! I am so excited to have it up my sleeve now, it is EXACTLY what I was looking for! 😀

I have written a nice working SUMPRODUCT formula - =SUMPRODUCT(--([DLP1.xlsx]InvRegister!$B$4:$B$99="Architect"),--([DLP1.xlsx]InvRegister!$J$4:$J$99=G$2),--([DLP1.xlsx]InvRegister!$K$4:$K$99=G$3),--([DLP1.xlsx]InvRegister!$L$4:$L$99=$A6),([DLP1.xlsx]InvRegister!$N$4:$N$99))

I'd like to replace "Architect" in first part of formula with a cell reference (A1) so I can change the role in A1 and have formula change accordingly.

When I put A1 in place of "Architect" then I get no values returned by formula...

Brainwave, solved it myself replaced Architect in A1 with ="Architect" and it works, is there a way to just have Architect in A1 or is my workaround the solution?

Usually if I use (array1=value1) in my formula it counts as an array formula, but this example works just by pressing enter. Why is that?

Thank you. This works

Hi Chandu, thanks for the explanation above. It proved very beneficial.

Further, i have a query in the example explained above:

Can i use the sumproduct formula if i have two conditions in the SAME COLUMN. Like:

to calculate the total sales for Luke and Hansolo both inclusive, in the region WEST..

I am using this formula but not getting 0 as the answer:

SUMPRODUCT((A1:A10="Luke")*(A1:A10="Hansolo")*(B1:B10="West")*C1:C10)

@Umang

Yes you can use multiple Conditions

But you can't do it as you suggested

=SUMPRODUCT((A1:A10=”Luke”)*(A1:A10=”Hansolo”)*(B1:B10=”West”)*(C1:C10))

This is because the the * between each range is acting like an "And"

So A1:A10 can be = to Luke but it can't also be equal to Hansolo at the same time

You can try something like:

=SUMPRODUCT((A1:A10=”Luke”)*(B1:B10=”West”)*(C1:C10))+SUMPRODUCT((A1:A10=”Hansolo”)*(B1:B10=”West”)*(C1:C10))

You can also do 2D lookup/sums

You can read about those here:

@Hui

Thanks for explaining where I was going wrong. Ideally what I was doing should throw an error because that is not a viable condition. Neway I understood the alternative u suggested. Thank you 🙂

Hey Chandoo. This is great. I have a slightly different issue I am currently dealing with.

My current formula is this:

=SUMPRODUCT(($AK$1:$DS$1=$A23)*($AB$2:$AB$4066=C$1)*$AK$2:$DS$4066)

and that works perfectly. The formula works to find the values in Columns B, D and F as they are named uniquely (in the formula they are referred to in A23, A24 and A25).

However, I also need to return the values for column C, E and G which are all named identically. Is there way to offset the above formula? Or to look at the column next to where the condition is met?

Thanks.

Hi Chandoo,

I was looking for a formula where you can find the value of a cell based on two criterias - one in a row and the other in a column (i.e. the intersection of the row and column).

Like the one stated above. I think it can be done using Index and Match function but I am finding it confusing. Can't do it manually since the data on which I am working is huge. Can you help me?

=VLOOKUP(G2,A2:E5,MATCH(H1,B1:E1,0)+COLUMN(B1)-(COLUMN(B1)-1),FALSE)

where

G2 contains required row header (north)

A2 to E5 is your complete data set with row headings (exclusive of column headers, i.e. ABC, EFG,...)

H1 contains the column head required (i.e. PQR)

B1 to E1 has the actual column heads (i.e. ABC, EFG,..)

B1 is the first column heading cell

Hi Chandoo,

Thanks for the prompt reply. It does work but can you elaborate on how the formula works? Also how would you use the above formula to auto fill the other cells in the example (i.e. we drag or copy the formula to other cell to give the result for the modified criteria automatically)

Hi Pushpa,

You can do this using index(match(),match())

=INDEX($C$3:$G$7,MATCH($B12,$B$3:$B$7,0),MATCH(C$11,$C$2:$G$2,0))

Where your top table starts at B2 & your bottom table starts at B11 the above formula goes in C12.

This can be copied to other cells in the target table.

I see a huge potential with my work to use this formula especially when you replace "Luke Skywalker" with a reference cell, essentially using this as a Vlookup with multiple arguments.

I've tried it twice now and just can't get to work. The test VLOOKUPS I tried to make sure that there wasn't some sort of formatting error making it a reference error. but I keep getting the same #REF.

Let me Explain Further

I have Sheet Data

Column A is Branch

Column B is Product Class

Column C is SKU

Columnc D is QTY Billed

Sheet Report

Column A is Branch

Column B is Product Class

So my formula (in Sheet Report) looks like

=SUMPRODUCT(--(Data!A$2:A$1000=A2), --(Data!B$2:B$1000=B2), Data!D$2:D$1000)

A Vlookup calling A2 in the same range works and so does B2, but get #REF when I use this.

Hello,

I have been attempting to get this figured out and I can not seem to figure it out it's not doing what I want it to 🙁

I am grabbing data from one tab to display on another tab:

I am needing if a range of cells ="Jane Doe" and another range of Cells ="January" to also grab to points from another range adding them up so the end tells me Jane Doe in the month of January had a total of 600 points received...

Any help is greatly appreciated

@Hmm

Can you post a sample file ?

there a few limitations when doing this.

1. the selected data in column 1 (names), column 2 (months) and column 3 (points) should be the same number of rows.

2. assuming that the data is such that Sheet1 has 3 columns:

A: names of people

B: names of months

C: points earned

in sheet 2, we can write

=SUMPRODUCT ( (Sheet1!A2:A26=Sheet2!A2) * (Sheet1!B2:B26=Sheet2!B2) * Sheet1!C2:C26 )

Given that in Sheet 2, cell A2 contains the name of the person you want the data for (for example Frank Doe) and B2 contains the month for which you want the data (for example March).

you can also do

=SUMPRODUCT((Sheet1!A2:A26="Frank Doe")*(Sheet1!B2:B26="March")*Sheet1!C2:C26)

I am attempting the following:

=SUMPRODUCT(--($D$2:$D$15=J$3),--($E$2:$E$15=K$2),$F$2:$F$15)

But i am getting 0 returned

Is it possible to reference a cell rather than a string like:

=SUMPRODUCT(($D$2:$D$15="FR")*($E$2:$E$15="Pierre")*($F$2:$F$15))

Which does return data?

When I try:

=SUMPRODUCT(($D$2:$D$15="FR")*($E$2:$E$15="Pierre")*($F$2:$F$15))

I get a result but when I change the strings to a cell reference it returns a 0.

Any idea what I am doing wrong?

@Lee

I'd try:

=SUMPRODUCT(($D$2:$D$15="FR")*($E$2:$E$15="Pierre"),($F$2:$F$15))

Copy and paste this

Then edit the formula and manually retype the " characters

Also check the Data in Column D & E doesn't have spaces or other non-printing characters in the cells

Check that Column F has numbers and that they aren't text

Select two cells in Column F, the lower right Status Bar of the Excel screen should show the total if they are numbers and the count if they are text

Can you post a sample file for more specific help ?

1. make sure that you are using the same text case (upper case and lower case)

2. make sure there are no spaces in the reference cells (at the start or at the end of the text)

3. try CTRL+SHIFT+ENTER (entering an array formula)

can you share the data is possible?

Hello,

This sumproduct formula is not working with me in excel 2010. I tried the same way as it has been taught above, but however the value or the answer returned is always zero. If you can please help me out.

Thanx

@Ali

Can you post a copy of your formula as well as a copy of some data

Hi Chandoo and Team,

I am learning this Sumproduct with one of your sample data (vlookup-on-multiple-conditions.xl).

SUMPRODUCT(lstNetSales,--(lstSalesman="Joseph"),--(lstRegion="North"),--(lstProduct="FastCar"), --(lstMonth=valMonth)) returns 1592

whereas with the same formula when I replace ONLY the valMonth with the actual date format (1/1/2007) it returns 0

SUMPRODUCT(lstNetSales,--(lstSalesman="Joseph"),--(lstRegion="North"),--(lstProduct="FastCar"), --(lstMonth="1/1/2007")).

Also when I use the table reference

SUMPRODUCT(tblSales[Net Sales],--(tblSales[Salesman]="Joseph"),--(tblSales[Region]="North"), --(tblSales[Product]="FastCar"), --(tblSales[Month]=valMonth)) returns 1592

SUMPRODUCT(tblSales[Net Sales],--(tblSales[Salesman]="Joseph")*--(tblSales[Region]="North")*--(tblSales[Product]="FastCar")*--(tblSales[Month]=-valMonth)) returns 0.

Please let me know how this calculates.

Appreciate your help.

Thanks

Mush

Any help on the previous queries I posted with using the variable and the actual values with SumProduct ?

Hi Chandoo,

Great site here - much appreciated. Wonder if you can help me with some syntax I am clearly getting wrong.

==========================================

I have Excel 2010 and using SUMPRODUCT FUNCTION - I am unable to do date comparison

==========================================

I run a small share investment club and of course use Excel to keep track of our activities. On one worksheet (Asset worksheet) I am trying (for each company we hold) to add up the dividends received for the past year (today-365) from values contained in another worksheet (Cash Account worksheet).

I am using Excel 2010 and an example of my Formula is:

=SUMPRODUCT(('Cash Account'!$C$7:$C$350=A4)*(TEXT('Cash Account'!$A$7:$A$350,"ddmmyyyy")>$T$1)*'Cash Account'!$G$7:$G$350)

WHAT I AM TRYING TO DO:

A4 contains Name of company (let's call it ACME).

$T$1 contains TODAY()-365.

Cash Account column A has Dates.

Cash Account column C has Company Name.

Cash Account column G has Amounts to be added up.

Therefore I am trying to look up all instances of ACME in the past year and adding up corresponding values.

THE PROBLEM

I cannot get the date compare element to work (it might as well as not be there). I get a value returned that adds up all available values in column G (for ACME) even those from more than 1 year ago.

Therefore as more rows get added to the Cash Account sheet, the only way to get this calculation to work is by manually (every month) amending the formula to only look at specific sets of rows (i.e. change the 7:350 range) to only include the rows covering Today-365.

I have tried all sorts of ways to amend this element of the formula.

I have tried SUMIF and SUMIFS !!

I have tried formatting all the cells that contain the dates.

SO - ALL HELP AND IDEAS APPRECIATED - MANY THANKS

Thank you!

This site is awesome!

At first i was reading the Sumproduct explanation and was like,

"why is he using "- -" ?" But a quick scroll down to the comment section showed me that i was not the only one questioning that:)

Still lots to learn for me but this site will get me trough it.

Keep up the good work! Thanks again.

I love this formula (and the rest of your site as well) - it has saved me countless hours of work. I'm wondering if there is a way to apply this formula to multiple sheets in a book. I have one summary sheet and I need values to be pulled from 5 additional sheets. All sheet are formatted the same so essentially I need to say go to all sheets, return values in BK2:BK30 if X,Y,& Z criteria are met.

Thanks!

Thanks for your comments Shely.

Try the logic from here: http://chandoo.org/wp/2014/09/09/3d-max-formula-for-excel/

It may not work exactly, but you can improvise it to get what you want.

@Shely

=sumproduct((Sheet1!Range=X)*(Sheet2!Range=Y)*(Sheet3!Range=Z),BK2:BK30)

The ranges must all be the same height as BK2:BK30

It's OK to use just one "-" instead of "--", right? Because the product of two negatives is a positive.

@Peter

You use a single - to define a negative number

The use of two -'s is to multiply the range/array by a negative and then another negative, which is effectively the same as 1* or 0+

In this case it is forcing Excel to evaluate the Array of True/False values and convert them to values of 1 & 0 respectively

People use two -'s as it is the most efficient in terms of calculation speed

Hi Chandoo,

I'm having a lot of trouble writing a formula. Or should I say everything I've written comes back wrong.

so this is what I'm trying to do;

Column B has Names

Column C is just telling me if they still work for out company

Column D has the tier level in it (T1,T2,T3)

Column E has equipment #

Column F has Die #

Column G has hours need to run the job before they can test out

Column H has total hours running that job

Column I has date

Column J has points

Column K as date

Column L has points

All other columns go date then points

So what I'm trying do is;

Look for a name

then look for a tier level

then add the points in j, l, n, p and so on.

When I use sumproduct for just looking up the name and level and 1 points column it works great but then I try to add the other columns and I get a N/A or Name

Here is the last one I wrote tried many ways but still not doing what I need.

=sumproduct(--B:B=K2),--(D:D=K3),(J:J,L:L))

Please help

thanks

@Baby734

Try:

=sumproduct((B:B=K2)*(D:D=K3)*(J:J)*(L:L))

I'd also recomend limiting the column sizes

so: =sumproduct((B1:B1000=K2)*(D1:D10000=K3)*(J1:J1000)*(L1:L1000))

is 1/1000th the size of the whole columns and will be correspondingly faster

If that doesn't work

Can you post a question and a sample file to the Chandoo.org Forums

http://chandoo.org/forum/

@Hui- Re: limiting column sizes: Isn't Excel / SUMPRODUCT smart enough to know when it reaches the last used row in the spreadsheet? Seems to me if the formula is written to limit the number of rows there must be some mechanism to keep it from breaking as the amount of data increases.

@Clif

Unfortunately not, The user must make those assumptions or allowances at all times.

A simple test in a blank/new worksheet

=COUNTA(--(A:A)*(B:B)) Ctrl+Shift+Enter

=1048576

Yet there isn't a piece of data in site

Hi,

I have two columns of data column H is due date and column I is completed date. I am trying to use the sumproduct function to count the number of cells in Column H that are overdue that don't have an associated completed date in column I.

I have tried the following but it doesn't seem to work:

=SUMPRODUCT(--(I2:I138=""),--(H2:H138="<"&TODAY()))

If I change the second array to look for text (ie "TBD") it works and gives me to correct answer so it appears to be something to do with looking for dates. Any help would be appreciated.

Hi,

As you took name "luke skywalker" in above example,say we want to calculate the sales of "west"region for "luke skywalker""luke moonwalker"," luke starwalker" and other similar names as well.

How could we calculate the total sales of all names in "west" region ?

Please assist.

Sumif() sounds just about right for your query

i mean ki aap

hi kailash,

its very simple .

suppose aapka opening balance hai 2000

then sale 1200

Apr opening - Apr sale- Apr closing - may sale - may closing .

2000. 1200. =a2-b2(800). 500. c2-d2

sales Ka formula h-

opening+primary - sale= closing current /opening next month

Chan,

Where is the excel spreadsheet so I can follow along and do the example?

It's hard to understand by chance reading. Thanks.

I feel SUMIFS formula is more easy rather than sumproducts.

Thanks

perhaps there are leading spaces or special characters in your text.

if you could share your sample file, it would be great.

@Mohammed

Your formula goes from Row 2 to 10

Hi Team,

can you pls explain where we can use sumproduct.

Thanks,

Anoop

@Anoop

You can use Sumproduct anywhere you want to:

1. Sum the results of multiple ranges multiplied together

2. Sum the results of multiple ranges multiplied together subject to criteria

3. Do simple to very complex conditional Counts of ranges, ie: Count the number of cells in a range where a number of fields are equal or not equal to values

4. Do simple to very complex conditional Sums of ranges, ie: Sum the cells in a range where a number of fields are equal or not equal to values

A lot of the functionality of point 2 is now available by using Sumif/Sumifs or Countif/Countifs, but even these have limitations that Sumproduct doesn't

03/11/2004 3/11/2025

try

=A1+DATE(20,0,0)

if the date format is not recognized, then you can try

=DATE ( MID(A1,7,4), MID(A1,1,2), MID(A1,4,2) )+ DATE(20,0,0)

Hello,

I done reading SUMPRODUCT explaination until the end, good explaination.

But i dont know whether it is the right function to work with my array formula.

Would u comment my array formula which is not working as expected

=IFERROR(IF(AND($D$8="HIGH";$E$8>=1);MAX(I8;INDEX(($B$8:$B$2222)+($E$8:$E$2222);(SMALL(IF(($C$8:$C$2222=$H$8)*($E$8:$E$2222>=1)*($D$8:$D$2222="HIGH");ROW($D$8:$D$2222)-ROW($B$7);"");J7))));IF(AND($D$8="AKUM";$E$8>=1);I8+INDEX($E$8:$E$2222;(SMALL(IF(($C$8:$C$2222=$H$8)*($E$8:$E$2222>=1)*($D$8:$D$2222="AKUM");ROW($D$8:$D$2222)-ROW($B$7);"");J7)));""));"")

My formula will only work as expected when D column only fill with 1 system, and meet failure when it's forced to calculate within random system.

Suppose that I have a bunch of names that all start with Luke, but different last names.

How do I use this to find all of the Lukes (regardless of their last name) for all "West" regions and return the sales?

Your help would be greatly appreciated.

Thank you.

column B has all the names

column C has regions

Column D has sales amount

----

in column D, apply this formula: =IFERROR(IF(SEARCH("luke",B3)=1,1,0),0)

it will help you find if the first name given in column B is Luke... it will

once you get all the lukes, go with this:

=SUMPRODUCT((C3:C11="East")*(E3:E11=1)*(D3:D11))

Well I really liked studying it. This post offered by you is very effective for proper planning.

How are you, nice internet site you’ve going here.|

I did not understand it. I think you need to elaborate it more

I could not understand why you used SumProduct to calculate Luke sales in west, if you can same result using sumifs functions. Kindly elaborate.

@Muhammad

2 reasons:

1. Because Sumif/s Countif/s are new functions and only have been available since Excel 2007/10

Sumproduct has been doing the heavy lifting since Excel was introduced

2. You also cannot perform math on ranges in Sumif/s, where you can in Sumproduct

I have two work books with each work book have one work sheet

I am using workbook two to gather information from workbook 1 rows B5:B100 and rows C5:C100 Row B has job titles and row C has level of education. I am trying to come up with a formula that both statements have to be true for the formula to count.

So if row B has Student/ professor/ accountant/ student/ student/ accountant

Row C has High school/ college/ high school/ college/ college/high school

If I want to know how many student have a high school education it would come back with 1 even though student is listed three times only student and high school show up one.
