Percentage Decrease Calculator

Calculate the percentage decrease between two numbers, or reduce a number by a percentage.

What is the Percentage Decrease Calculator?

Percentage decrease measures how much a value has fallen relative to its original value.

How does it work?

Subtract the new value from the original, divide by the original and multiply by 100.

Formula

% decrease = (Original − New) ÷ |Original| × 100

Example

A fall from 120 to 90 is a 25% decrease. Reducing 500 by 15% gives 425.

Frequently asked questions

Can a decrease be more than 100%?

Only if the value goes below zero, for example a profit turning into a loss.
