Embed our calculators on your site — free

Writing about seller fees, mortgages, or freelance pricing? Give your readers a working calculator instead of a static table. Pick any of our 26 calculators, copy one snippet, and paste it into your article. No signup, no API key, and the rates stay current automatically.

Paste it anywhere HTML is allowed — WordPress (Custom HTML block), Ghost, Webflow, Notion (Embed), or your own site. The calculator stays up to date automatically; we just ask that you keep the “Powered by TallyCrunch” credit intact.
