Percentage Increase Calculator

Calculate the percentage increase from one number to another, or increase a number by a given percentage.

What is the Percentage Increase Calculator?

Percentage increase expresses growth relative to the original value.

How does it work?

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

Formula

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

Example

A price rising from ₹80 to ₹100 is a 25% increase. Increasing 200 by 15% gives 230.

Frequently asked questions

Why is a 50% drop followed by a 50% rise not back to the start?

Because the rise is measured on the smaller value: 100 → 50 → 75.
