The MOD function is very simple but it can be used to do wonderful things in Excel.

It returns the remainder after you divide one number by another.


=MOD(number, divisor)
Argument Description
Number The number that will be divided by another number.

The number by which the first number will be divided.

Example - Simple

  1. Type =MOD(
  2. Type the first number or select a cell that contains that number.
  3. Type a comma and then type the second number, which is the number that we will use to divide the first one.
  4. Hit Enter and that's it!

You can see that the remainder of dividing 10 by 4 is 2.

Example - More Helpful

So far, this might not help you unless you are doing straight-up math in Excel. However, we can use it to check what row or column we are in and this can really help us to create more powerful and useful spreadsheets.

If we divide 5 by 2, there will be a remainder, but if we divide 5 by 5 or 1, there will be no remainder and it is when there is no remainder that we can use this function to determine intervals. It sounds confusing so just pay attention to the example.

Type =MOD(5,1)


Hit Enter and we get 0


Now, combine this with the ROW() function, which returns the number of the current row, and we can get intervals:

Type =MOD(ROW(),2)


Copy the formula down and we get this:


Using that pattern we can do everything from incrementing a value to automatically shading rows.

The MOD() function by itself is not so great, it is when we combine it with other functions that it shines.
