Percentage Calculator

Fastest way to calculate discounts, tips, interest and other percentages.

The percentage calculator is a free and easy to use app that will make your calculations much simpler.

There are 4 different percentage calculations you can perform, and those are: value, change, increase, decrease, conversion and growth, with hopefully more to come in the future.

Value calculates how much x% of y is, for example, 25% of 40 is 10.

Change calculates how much y changes if x% is added/subtracted from it, for example 50 + 20% = 60

With the conversion, you can convert fractions into percentages, for example, 1/5=20%

Growth is similar to change however, it's not a one time change, but a change over many periods. For example, if you set 20 to change by +50% over 3 periods, the calculation will go like this: 20+50%=30; 30+50%=45%; 45+50%=67,5; with the final result being 67,5.

The lock feature- you can lock one of the 3 or 4 fields, which will be the one that is calculated. This means you can do reverse calculations. For example, if $10 is 25% of the price, the full price is $40.
