Increase by percentage

Excel formula: Increase by percentage
Generic formula 

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.


In the example, the active cell contains this formula:


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:

=70 * (1 + .2)
=70 * (1.2)

Note: you must add 1 to the percent if you want to increase a number. If you don't, you'll get the amount of the number the percentage represents.
