PercentDiff is the original multi-result percent calculator application.

Using PercentDiff is incredibly easy. There are two tabs. One for two numbers, and one for a number and a percentage. Input your numbers on either tab and all values will be calculated.

The two modes currently available are:

A. % Change (Number 1 to Number 2)

This mode will calculate:
1. Percent increase
** This mode can also be used to calculate gross sales markup

2. Percent decrease
** This mode can also be used to calculate gross margin

3. Percent difference

4. Number 1 as a percent of Number 2

5. Number 2 as a percent of Number 1


B. % Of (Percent of number)

This mode will calculate:
1. Percent of X

2. X plus percent
** Can also be used to calculate markup on a product

3. X minus percent
** Can also be used to calculate markdown on a product

4. X as a percent of an original number

5. X as a percent increase of an original number

6. X as a percent decrease of an original number
