Why donate to Crypto Math Tools?

Donations help keep the calculators free, private, and fast while covering hosting, development, and ongoing site updates.

Do I need to donate to use the calculators?

No. All calculators remain free to use. Donations are optional and only support the project.

You can support the site with crypto tips or with the fiat donation link on this page.

CryptoMathTools is built by an independent developer. No paywalls, no aggressive tracking, just pure mathematics.

If these calculators saved you from a liquidation or helped you optimize a trade, consider sending a small tip to keep the servers running.
