Embed our calculators — free
Put any of our 50 calculators — or our reference tables — on your own website, blog or intranet with a single snippet. They're fast, mobile-friendly and maintained by us, so they stay accurate without any work on your end.
How it works
- Open the calculator you want on this site.
- Scroll to “Embed this calculator on your site” and copy the code.
- Paste it into your page's HTML where you want the tool to appear.
That's it. The calculator loads in a lightweight frame that resizes itself to fit, works on every screen size, and always reflects our latest version — no scripts to maintain or update.
Why embed ours
- Free — no account, no fee, no catch. Just keep the small attribution link.
- Always current — we maintain the formulas and fix issues; your embed updates automatically.
- Fast & private — near-zero JavaScript, and the calculations run in the visitor's browser.
- Accessible & mobile-friendly — built to the same quality bar as the rest of the site.
