    Percentage formula

    Hey all, I've got a quick question for you in regards to percentages and excel.

    I want to create a formula where I can have a starting value, say 500, and subtract it by a percent, and then take that answer and subtract it by the same percentage ad infinitum.

    I'm using the "=A1*(1-A2/100)" formula (A1 is original value, A2 is percent value) in A3; is there a way to get Excel to then change the formula to "=A3*(1-A2/100)" without me having to manually change A1 to A3, A4, A5...?

    I hope that makes sense.

    Thanks for giving pause to read this and I look forward to any and all responses!

    Make A2 absolute: $A$2

    Or, it would make more sense to move the percentage to a different cell outside column A

    Thanks! I moved the percent to B1 and made it absolute. Changed the formula to A1*(1-$B$1/100) and it works like a charm.

    I appreciate your reply!
