Adding Formula in Excel

[BlDexter]

How do I add a formula to add 3% to a specific column of different numbers, say “B” and then in column “C” get the resulting sum. There may be 25 different amounts in lines 1-25 but I’d like column “C” to reflect the sum of that calculation.

Hi @BlDexter 

Is this what you need?

=B1 * 1.03 then copy the formula down
