Percentage Increase Calculator

Enter the original value and the new value to calculate the percentage increase from the original value.

How It Works

The calculator subtracts the original value from the new value, divides the increase by the original value, and multiplies by 100. The result shows how much the new value increased relative to the original value.

Formula

Percentage Increase = ((New − Original) ÷ Original) × 100

Example

An increase from 50 to 65 is a 30% increase because the value increased by 15, which is 30% of the original value of 50.
