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

We strive to make our apps as simple to use as possible.

Please FEEL FREE TO EMAIL US feedback. We would like to know how users interact with the app and how we can improve upon it.

Future versions will require iOS 5 or iOS 6 as a minimum. Please upgrade.

Customer Reviews

Simple yet wonderfully useful

Some of the best ideas are simple and simply useful. Even if you can do the math in your head, this app works faster and gives you more options to consider.

What would make this app absolutely perfect would be the addition of some 1-button functions like to round the answer up or down (eg, press once to round to the nearest whole number, twice to the 10s, 3x to 100, etc). I'm sure others can find more functions, but rounding would be an excellent add-on. Heck, make it a 99-cent add-on and I'll buy it!

Fast and practical!

This app is very useful for me because I work in a restaurant and I'm constantly needing to find out percentages. It also is two steps ahead of me with already providing the amount with the percentage added or subtracted the moment I type in the percentage request. It's super easy to use!

Great way to cheat at life

I sell a lot of stuff on eBay and this app helps for posting sales! Certainly beats trying to do the math for percentages off on a sale. Very easy to use and multiple features that give you several differences to use.
