This is exactly what visitors to your site will see.

Free forever

No account, no API key, no analytics injected into your page. The iframe is sandboxed by the browser.

Always up to date

Bug fixes, new holidays, and feature improvements ship to every embed automatically.

Fast & lightweight

Static HTML, no heavy SDKs. Renders in well under a second on typical pages.

Terms of use

You may embed Calcadian calculators on any public or internal website at no cost.
Please keep the small "Powered by Calcadian" attribution intact.
Don't wrap the iframe in a way that obscures branding or implies endorsement.
We may update calculator UI or behavior; we won't break the embed URL pattern.
