Summary

The Percentage Calculator is a free website tool from EP Apps. It calculates percentages, percentage change, discounts and reverse percentages from the numbers you enter.

How the tool works

The calculation runs on your device, in your browser. The numbers you enter are not sent to us or stored on a server or in your browser.

Accuracy and your responsibility

We aim for the results to be correct, and the page shows the calculation it used so you can check it. Results are displayed to up to six decimal places. Check important results yourself before relying on them for financial, tax, legal or other decisions. The tool does not know about rounding rules, taxes or fees that apply to your situation.

No warranty

The tool is provided as is. We cannot guarantee that it is free of errors or suitable for every purpose.

Changes and contact
