# Percentage of a Percentage Calculator

The percentage of a percentage calculator will multiply one % by a second % to get the cumulative value. It will also take an original value and calculate a new value after the first percentage is applied and then a final value after the second percentage is applied.

For example, suppose the first percentage is `25`

and the second is `33`

. The calculator will compute `(0.25)(0.33) = .0825`

or `8.25%`

. Now applying this to numbers, suppose the original number is `10`

, take `10 * 0.25 = 2.5`

, now multiply `2.5`

by `0.33`

to get `0.825`

.

The user of the calculator can also enter the original value, value after first percent and final value and the percentages will be calculated.
