Percentage Calculator

Work out a percentage of a number, useful for discounts, price changes and quick estimates.

How to use this tool

This tool is designed for quick everyday estimates. Enter the information you have, press the button and use the result as a practical guide. It does not store your input and it runs in your browser.

When to double-check

For financial, tax, legal, medical or business-critical decisions, always confirm the answer using official documents or professional advice. Simple calculators are helpful for planning, but they cannot cover every special rule or exception.
