Embed a Calculator on Your Site
Put any Calci.in calculator on your site with two lines of HTML. Free, no sign-up, no API key — pick one, copy the snippet, keep the credit line.
Height
The iframe is 100% wide and scales to its container. Only the height is fixed, so pick the one that fits without an inner scrollbar.

EMI Calculator by Calci.in — this is exactly what your visitors will see.
What you are allowed to do
- Use it free, on any site — personal blog, company page, client work. No sign-up, no API key, no limit on page views.
- Keep the credit line. That second line of the snippet is the whole price. Remove it and you are using the calculator without saying where it came from.
- Style the frame — border, radius, width, margins are yours to change. The calculator inside follows your visitor's light or dark preference.
- Do not copy the calculation out and pass it off as your own tool. Embedding is welcome; lifting the formulas is not.
How the embed behaves
- Nothing loads until it is needed. The snippet carries
loading="lazy", so an embed below the fold costs your page nothing on first paint. - No ads, no cookie banner inside the frame. Consent belongs to the site your visitor is actually on, so the embedded view drops our header, footer, ads and banner.
- The numbers stay in the browser. Every calculation runs client-side. What your visitors type is never sent to us, and the embed works offline once loaded.
- The credit link opens your page's top window, not a site inside a 640px box.
