Percentage Calculator Online

We have several different percentage calculators for you to use.

Each calculator performs a slightly different job - make sure you select the correct one for your task.

There are also support pages with our calculator pages which explain how the calculators work, complete with worked examples.

The calculators have been color-coded for easy identification.

This short video shows our range of percentage calculators, what they do and how they work.

This is the calculator to use if you want to find a percentage of a number.

Simple choose your number and the percentage and the calculator will do the rest.

If you need to find the percentage increase/decrease between 2 numbers, then this calculator is the one you need.

Simple input the original number, then the new number and the calculator will tell you the percentage increase or decrease.

Sometimes you are told what the percentage increase/decrease is, and you are also told the final number.

Your task is then to find the original number before the percentage increase or decrease.

Our reverse percentage calculator will help you to find the original number.

If you need to convert a percentage to a fraction - either a decimal fraction or a fraction in its simplest form, then use this calculator.

You can also use the fraction to percentage calculator for converting any fraction into a percentage.

This calculator takes a percentage and converts it at the click of a button.
