Many of us start using Excel to keep track of something. And along way, we realize that Excel has a powerful feature called formulas, using which we can automate a lot of things. BOOM! Before we realize, we are in the thick of VLOOKUPs and SUMIFs.
But, along way, we also pick up a few bad habits or believe a few myths. Today, lets bust 10 Excel formula myths that we hear often.
1. Shorter Formulas are Better
I think it is human tendency to shorten and optimize things. We take great pride if we can shrink a task that takes 10 minutes to 12 seconds. But is it the case with Excel Formulas?
In my opinion, any formula that does the job is better. It does not matter how short or long the formula is. Often, we can come up with a reasonable formula in few minutes, but we waste several hours trying to shorten it. Time that could be used for better things like impressing your boss or shipping a product.
2. IF Formulas are Bad
I dont know where this comes from, but I hear it often. Oh, why use IF formula, as if it is going to slow down the computer drastically. Well, for most cases, we are dealing with reasonably sized data and Excel is fast enough to calculate formulas whether they are IFs or REPTs or something else.
So go ahead and use IF formula, if that is what you need to use.
3. VLOOKUP is slower
Ok, here is another one. For some reason people believe that VLOOKUP is slower than alternatives like INDEX+MATCH, OFFSET+MATCH, MATCH, Array formulas. Well, in my private tests, I found mixed results. VLOOKUP performance is almost same as that of other alternatives for small and medium (10000 rows) sized data sets.
Of course, if you have a workbook with million rows, then you should spend time looking for the fastest formula. Otherwise, just use VLOOKUP and be done.
4. Helper Cells, Helper Columns are Lame
Again, another myth that has no reason to exist. Each Excel sheet has 17179869184 cells and there is no reason why we should not use a few to support us in our formulas or models. Use helper cells, they keep your worksheet simple and easy to understand.
5. Formulas should start with = sign only
Do you know that you can start a formula with + or – sign too?
Well, you can type -SUM(1,2,3) to get -6 in a cell.
Similarly, you can type +SUM(1,2,3) to get 6 in a cell.
PS: You can also begin a formula with @ sign. I am not sure if there are more…
PPS: You can put ‘ before the formula if you just want to show the formula instead of running it. So if you write ‘=SUM(1,2,3), Excel would show =SUM(1,2,3) in a cell (instead of 6)
6. Formulas cannot refer to other Excel Workbooks
Well, that is not correct. You can refer to data in other workbooks in an Excel formula. For eg.
=SUM(sales.xlsx!q1Sales,2000,$H$2:$H$13)
will sum up the named range q1Sales in Sales.xlsx workbook, the value 2000 and the cells H2:H13
Remember, if your workbook is closed, you need to put the full path, like this:
=SUM(‘C:\full\folder\path\sales.xlsx’!q1Sales,2000,$H$2:$H$13)
PS: Certain formulas do not work with closed workbooks.
7. Formulas should be written in a cells only
Well, this is wrong. You can use formulas in named ranges, conditional formatting, data validation. You can also assign formulas to drawing shapes, chart elements (like titles, labels etc.).
See these examples:

8. We cannot copy a formula without changing references
Of course you can. If you want to have the same formula as in the cell above, just press CTRL+’
You will get the same formula and you can modify it as you want.
If you want to have the same formula elsewhere, just go to the formula cell, press F2, select everything (SHIFT+HOME), copy (CTRL+C).
Now go to the target cell and press F2 and paste (CTRL+V)
9. Formulas cannot do ‘x’…
May be they cannot feed your cat or take your dog for walk or change a nappy. But there is a formula for almost everything. And Excel team at Microsoft is adding new formulas in each version. It wont be long before a =ChangeNappy(kidname, <optional dispose nappy>) appears. Well, may be.
But the best part is, you can create your own formulas, called as User Defined Functions. And once you start doing that, there is no limit to the possibilities. You can create a CONCAT() to add up a bunch of text values, a NETWORKINGDAYS() to calculate working days based on a custom weekend setup or anything. [More UDF Examples]
10. Formulas are difficult to learn
Only if you think so.
Excel formulas are very powerful and very easy to learn. You need to start slow and go one step at a time. It might take a while to wrap your head around the referencing styles and various formulas.
But once you learn a few simple formulas, rest of them will be easy to learn. And before you realize, you are in the thick of VLOOKUPs and SUMIFs.
Oh, wait, I said that already. But then who says we cannot repeat. That is another myth!
What myths you hear about Excel Formulas?
Thanks to all your emails, comments and forum discussions. I hear about a lot of myths and bad habits all the time, when it comes to Excel. I found that giving in to these myths limits our ability to do more.

I’d suggest simply using the subtotal function and filtering the data using the Win/Loss column. You get the same results and the formula is more comprehensible.
@John
That is one option.
There are times however when you want to see the whole data table or a filtered subset and still want to produce summary reports against an unfiltered field.
Is there a particular reason why you are using a comma and the unary (–) operator for the second array in the SUMPRODUCT formula? It seems to work the same if you were to string the arrays together using the asterisk (*). The advantage is that SUMPRODUCT treats the entire string of arrays as a single array.
@Mathew
Your correct, There is no difference.
I thought it may have been easier to explain this method.
Is there a way to do this on a large set of data? As in ~100,000 rows? When I try I get an error because the formula becomes too long. It says the max length of a formula is 8,192 characters. Excel 2010.
How do I incorporate a specific text within a cell for the second array. For instance, – -(C7:C13=”Apple”)
when I chose a specific text the formula does not work.
@RB
I am not sure what is the issue as if I use the sample data in the post the following work fine
Count:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)), –(C7:C13=”L”))
Sum:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)),(C7:C13=”L”)*(D7:D13))
You may want to check that there are no leading or trailing spaces in your list of Apples
I should have given a better explanation. Heres my situation. I have a column with cells filled with names like Column 1, Column 2, Pier 1, Pier 2, etc. If the cell just contained Pier and searched for that it works. But because it has other characters in the cell its not recognizing the pier. So how can I extract specific characters of a string of text in this formula?
Hopefully this was a better explanation
Hello-
This formula works pretty well for me except that it slow down excel and prevents some of my macros from working. I was wondering if there was a way to program this in VBA so that excel isn’t always trying to recalculate it. I would like to use a push of a button to get it to run then paste in a cell.
Thanks!
I am trying to sum filtered data in a column, but would want to ignore the negative values in the column. How to go about doing this?
@Akshay
Why not just add a filter to that column to only show the values greater than zero?
The negative values are required for reporting purposes, but their effect on the total is distorting the required output. Please advise.
@Akshay
I’d suggest making a post in the Chandoo.org Forums

I have this working for counting and summing, however, I have a list and for the second array, I need a criteria. That is, I’m looking for b13:b200=”01.??.??” or =left((a1,2) or something like that. These types of criteria matches do not appear to work as I get a blank as a result.
Thanks!
@Bob
As your formula b13:b200=”01.??.??” looks like you are trying to check the first day of the month of the range
What about trying Day(B13:B200)=1
Hai Experts,
i understood this formula well and working fine in MS Excel 2013
but when the same am trying to place in google Spreadsheet it shows error as
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 2014, column count: 1.” and as a result #VALUE! Appears in cell.
Can anyone please help me how would i get it done in Google Spread sheet
or is there any other formula as a substitute for this.
Thank you very much.
thanks for providing this.. but why does excel keeps on prompting Circular referencing in cell D3?
@Vivek
I don’t know
I just downloaded the file and it is working fine and not showing that error
Goto the Formulas, Calculation Options Tab and check that Calculation is set to Automatic
What version of Excel and Windows are you using ?
I know that this forum is for MS Excel, but I am trying to help someone who is working in Google Sheets. The below formula works in Excel but Google Sheets returns:
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 39000, column count: 1.” and as a result #VALUE! Appears in cell.
This is the same problem asked by Srichirin above. Does anyone know if there is a formula for Google Sheets that will replicate what MS Excel does?
=SUMPRODUCT(SUBTOTAL(3,OFFSET($C$6:$C$39500,ROW($C$6:$C$39500)-MIN(ROW($C$6:$C$39500)),,1)),- -($C$6:$C$39500=H1),($D$6:$D$39500))
Trying to find a SUMPRODUCT formula that counts the word Closed by date for the last 7 days in a filtered list.
=COUNTIF(M:M,”>”&TODAY()-7) works ok for unfiltered count Column M contains Closure dates (blank if open) and Column L is Status Open or Closed

I used this formula and worked like a charm! But, now I’ve been requested to use it but adding not one but two criteria in the same formula. For instance the sum I was doing added negative and positive numbers. I’ve been asked to use the exact same formula but adding that only positive numbers were considered… any idea on how to do this?
How exactly do you do sum filtered cells when two criteria are need not just one?
Thank you so much brother literally I have been struggling since morning to get the sum of the filtered category, however, after reading your blog attentively i got my solution, so thanks a lot once again.
