Free Percentage Calculator

Solve any percent problem in seconds

Three modes for the three percent questions people actually search for: what is X% of Y, what % X is of Y, and the percent change from X to Y. Pure client-side, no signup, your last inputs persist in your browser.

Choose a mode

Enter a percentage and the value to multiply against.

Result

Pick a mode, enter the values, and the result updates as you type. Your last mode + inputs persist in this browser.

Your last mode + inputs persist in this browser's localStorage — clearing site data will erase them. Zero is a valid input (e.g. 0% of Y = 0, a 0 over a non-zero whole is 0%).
