How to use the Percentage Calculator

Enter the values for the calculation you need. Results update immediately as you type.

How it works

This calculator covers several common percentage questions: finding a percentage of a value and measuring the percentage change between an original and a new value.

Example: Twenty percent of 250 is 50. A value moving from 80 to 100 has increased by 20, which is a 25% increase relative to the original 80.

What to keep in mind

Percentage change uses the original value as its denominator. A percentage change cannot be calculated from an original value of zero.

Frequently asked questions

What is the difference between percentage points and percent change?

Percentage points compare two percentage values directly; percent change compares the difference with the original value.

Can I use negative numbers?

Yes, although the meaning should be interpreted carefully when the original or new value is negative.
