FAQ

Is Percentage Calculator really free?

Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.

Is anything I type into Percentage Calculator sent to a server?

No. Every keystroke is computed with a pure JavaScript engine (Web Worker for heavy inputs) inside this page. Close the tab and your data is gone — unless you explicitly download or share it.

What should I enter in "Value"?

Put your value here — for example: 200. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.

I normally use Bankrate — why switch?

If you are tired of ad-heavy pages that show a number with no explanation of where it came from, MoneyMetric is the alternative: every result arrives with its formula, tables and charts — and your figures never leave your device.
