Today, lets learn OFFSET formula.
What is OFFSET and why bother using it?
OFFSET formula gives us reference to a range, from a given starting point with given height and width in cells.
OFFSET formula syntax
OFFSET formula looks like this:
=OFFSET(starting point, rows to move, columns to move, height, width)
- Starting point: This is a cell or range from which you want to offset
- Rows & columns to move: How many rows & columns you want to move the starting point. Both of these can be positive, negative or zero. More on this below.
- Height & width: This is the size of range you want to return. For ex. 4,3 would give you a range with 4 cells tall & 3 cells wide.
And yes, All the arguments to OFFSET can be references to other cells. That means, you can write =OFFSET(A1,D1,D2,D3,D4) which will refer to a range
- Starting from A1
- Offset by D1 rows & D2 columns
- having the size of D3 rows & D4 columns
See below examples to understand the formula better.
OFFSET formula examples
Why use OFFSET?
Why not write a reference like A1:C4 directly?
Here are a few reasons why,
- Dynamic ranges: Reference like A1:C4 always refers to the range A1:C4. ie it is static. But sometimes, we want our ranges to be dynamic. This is required because our data is changing (every month new row is added, every time we launch a product new column is added etc.)
- We don’t know the exact address: Sometimes, we don’t know what our ranges actual address is. Rather, we just know it is starting from a certain cell etc. In such situations OFFSET is useful.
Understand OFFSET formula – Interactive Workbook
Since OFFSET formula is somewhat tricky to get, I created an interactive workbook so that you can understand how it works. When you input all the 5 parameters, the workbook highlights the range that your OFFSET will give. After playing with it for a few minutes, you will understand the formula better.
Practical use for OFFSET – Average of latest week
Lets say we monitor quality of a plant producing purple puppets. One of the KPIs we monitor is % of rejected puppets. We have been tracking the % of rejects by day in a spreadsheet that looks like this:
So how do we calculate average of latest week?
Assuming the values are in range C3:C18, we can write =AVERAGE(C12:C18)
BUT, WE NEED TO CHANGE THIS FORMULA EVERYDAY!!!
Even puppets would find that boring.
By using the OFFSET awesome sauce, we can write the AVERAGE formula once and forget about it.
=AVERAGE(OFFSET(C3,COUNTA(C3:C300)-7,0,7,1))
Lets break-apart this formula and understand
- To calculate latest week’s average, we need to go all the to the last data point and then get 7 rows from it and average those values.
- This is where COUNTA(C3:C300) – 7 comes in to picture. It counts how many values are there in column C and then subtracts 7 from it.
- The OFFSET would then starting point from C3 to latest week’s starting point.
- To know how this formula works, watch below demo.
OFFSET limitations
While offset formula can return with a dynamic range when you beckon, it does have few limitations:
- OFFSET formula is volatile: In plain English it means, whenever there is any change in your workbook, OFFSET formula is recalculated, thus keeping Excel busy a tiny bit longer. This is not an issue if you use OFFSET formula in a small workbook. But when you use lots of OFFSET formulas in large workbooks, you will end up cursing Excel as it takes too much time to recalculate.
- OFFSET formulas are tricky to debug: Because the references are dynamic, debugging a workbook with lots of OFFSETs can get tricky quickly.
Alternatives to OFFSET formula
There 2 fine alternatives to OFFSET formula.
- Use Excel Tables: Since Excel 2007, we can create tables from structured data and write formulas, create charts that refer to dynamic ranges with ease. Click here to know more about tables.
- Use INDEX formula: Although not exactly same as OFFSET, INDEX formula can also be used to generate dynamic range references. Plus, INDEX is a non-volatile formula, so it wont keep Excel busy unnecessarily. Know more about INDEX formula.
Do you use OFFSET formula?
For most of my dynamic range needs, I rely on tables or INDEX formula. I use OFFSET formula when I have to calculate values like average of latest week. In such cases OFFSET is an elegant solution.
What about you? Do you use OFFSET formula? In which situations do you use it? Please share your tips & examples with us using comments.

I would apply a filter and use function subtotal, with option 9. This way you can see multiple views based on the filter.
hey Chandoo, the solutions you proposed are very efficient, but if I wanted to be fancy I would do it this way .. the references are as your example workbook.
=SUM(INDIRECT("C"&(MATCH(F5,B5:B95)+4)):INDIRECT("C"&(MATCH(F6,B5:B95)+4)))
I like things simple:
=SUMIF(B5:B95,">="&F5,C5:C95)-SUMIF(B5:B95,">"&F6,C5:C95)
use something like: =SUM(OFFSET(B1,0,0,DATEDIF(A1,D1,"d")))
and have D1 be the date that I want to sum to.
In Excel 2003 (and earlier) I'd use an array formula to calculate either with nested if statements (as shown here) or with AND.
{=SUM(IF(B5:B95>F5,IF(B5:B95<F6,C5:C95,0),0))}
Note that I truly made this for BETWEEN the dates, not including the dates
I turned the data set into a table named Dailies.
I named the two limits StartDate and EndDate.
And used an array formula:
{=SUM((Dailies[Date]>=StartDate)*(Dailies[Date]<=EndDate)*Dailies[Sales])}
If I would still be using the old Excel I would do it as follows:
SUMIF($B$5:$B$95,"<="&H6,$C$5:$C$95)-SUMIF($B$5:$B$95,"<"&H5,$C$5:$C$95)
Works as simple as it is.
Regards
=sum(index(c:c,match(startdate,c:c,1)+1):index(c:c,match(enddate,c:c,1))
=sum(index(c:c,match(startdate,b:b,1)+1):index(c:c,match(enddate,b:b,1))
Great examples and thanks to Chandoo. You have simplified my work.
Hi! great tips I have found in your page, have you seen this
http://runakay.blogspot.com/2011/10/searching-in-multiple-excel-tabs.html
[...] I'm not sure I understand your question fully, but have a look at this: Sum of Values Between 2 Dates [Excel Formulas] | Chandoo.org - Learn Microsoft Excel Online [...]
Thank you! Thank you! Thank you!
=SUMIF(A2:A11;">="&B13;B2:B11)-SUMIF(A2:A11;"<"&A11;B2:B11)
awesome... thank yoo Chandoo!
which is most efficient and fast, if all are efficient ?
Thank you for this formula, I've just spent ages trying to find something to work on my data, I knew it would be possible! Don't care if others think there are easier/other ways to do it, you explained it so I understood it and could apply it to what I was doing so I'm happy!
The above said example is awesome for calculating values between dates,
can you pls let know how to calculate sale values if we have 10 sales boys for
ex: 1,rama

Hi
I have a list of people's names in column A, I have a list of dates in column B which records the dates they have been off sick, in column C I have either 1 if it is a full sick day or 0.5 if it is a half day.
What I would like to do is to add up the number of dates a specific person has been off within two dates.
For example, I want to look at my list of names and to find Joe Bloggs (column A), then add up all his sick days (column C). The start date will be in cell E1 and the end date will be in F1.
If this possible using SUMIFS?
List of names are in range A2:A100
List of dates in B2:B100
List of sick days (either 0.5 or 1 in C2:C100
The start date is in cell E2
The end date is in cell F2
Your help would be greatly appreciated.
Yes, with the help of SUMIFS you can have the solution.
Note: you need have an extra col. D2 where you will input Name of the person.
=SUMIFS(C2:C100,A2:A100,D2,C2:C100,">="&E2,C2:C100,"<"&F2)
Col. A Col. B Col. C Col.D Col. E Col. F
Name Date Sales
ABC 28-Jun-11 1 MNO 28-Jun-11 25-Sep-11
XYZ 29-Jun-11 0.5
MNO 30-Jun-11 1
PQR 1-Jul-11 1
Typo ERROR / Correction in formula:

Thanks for this - it solved the problem that I was having. However can someone please explain to me why the "" needs to be around >= and <= as well as why we need to add & in order for the formula to work? Thanks in advance!
This formula works perfectly as well. Any ideas?: =SUM(INDEX(C5:C95,MATCH(H5,B5:B95,1)):INDEX(C5:C95,MATCH(H6,B5:B95,1)))
ikkeman had posted the same thing.
I am trying to sum total a range of cells between date ranges ie column n has $ amounts column d has the transaction dates ie 1/3/2015 or 25/3/2015 or 25/4/2015 column b has the text saying drp or distribution - reinv
In another cell I am trying to sum or total (in column n) with the value of a range of different dates (column d) that contain different text (column b) ie cell n48 is 50, n65 is 85, n165 is 36
with the dates ie cell d48 is 1/3/2015, d65 is 25/3/2015 and d165 is 25/4/2015
with different text that says drp or distribution - reinv ie cell b48 is drp, b65 is distribution - reinv, b165 is drp
If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp then the total would be 50. Also if I wanted to sum the amounts between 1/4/2015 to 30/4/2015 with drp the sum total would be 36 If I wanted to sum the amounts between 1/3/2015 to 31/3/2015 with drp and distribution - reinv the sum would be 115
What would the formula be for these different questions
hope you can help, it has been driving me nuts and cant work it out
