The percentage of percentage calculator will multiply one % by a second % to get a 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 * 0.25 = 2.5, now multiply
0.33 to get
The user of the calculator can also enter the original value, value after first percent and final value and the percentages will be calculated.
