How to increase by percentage in Excel

If you need to increase a number by a certain percentage, you can use a simple formula that multiplies the number times the percent + 1.

Formula

=number*(1+percent)

Explanation

How this formula works

In the example, the active cell contains this formula:

=C6*(1+D6)

In this case, Excel first calculates the result of 1 + the value in D6 (.2) to get 1.2 which it then multiplies times the value in C6 (70) to get a final result of 84:
