I have two columns - they look like the following:

N      |  13
N      |  22
Y      |  13

The AMOUNT column is a value output from a condition,


I would like to SUBTRACT 3 from the AMOUNT column IF the YESNO column has a value of Y and I'm just not sure how to arrange this.

Any suggestions? What sort of function should I be looking at to make this happen?


Make a new column with the result of the new calculation, and use a simple IF command.

=IF(A2 = "Y",B2 - 3, B2)

enter image description here

If you don't want to make a new column, just append - IF(A2 = "Y", 3, 0) to the end of your command.

=IF(E16=1,"13",IF(E16=2,"22",IF(E16=3,"30"))) - IF(A2 = "Y", 3, 0)

You will of course have to replace A2 with whatever your YESNO column is.

  • Oh wow. Makes total sense (both suggestions). I'm partial to the second only because it doesn't require a new column. Works like a charm. And I've learnt something for the future. Thank you! – Wilhelm Warner Mar 5 '14 at 10:38
