## How to Find the Percent of a Percent

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.

## How to Find the Percentage of a Value

Percentage is the proportion of a part to the whole amount or the portion of a value and can be expressed as a fraction/decimal or as a whole number with a percent symbol. Solve the percentage, or portion of a value using the formula:

y = value × percentage ÷ 100

Simply put, multiply the value by the percentage and then divide by 100 to find the result.
