How to use this calculator
Embed free Calculato calculators in your website, blog or learning materials with a standard iframe. All available calculators have embed routes. No account or API key is required.
Choose a calculator and copy the code
Use the embed builder to choose a calculator, set its frame height and copy the iframe. Width follows your page container. The live preview lets you try the tool before publishing.
Paste into a Custom HTML or Embed block
Use a website editor that permits iframes. Custom HTML websites can place the code directly in their content area. Some site-builder plans and security plugins restrict frames. If your site uses Content Security Policy, allow https://www.calculato.co in frame-src.
Privacy, updates and limits
Inputs are calculated in the browser, but the iframe loads from Calculato, so visitors make normal hosting requests. Embeds need JavaScript and an internet connection and receive our calculator updates. Read each calculator’s assumptions before publishing. Export options vary. Height is configurable rather than automatically resized.
Example: embed a percentage calculator
Use https://www.calculato.co/embed/percentage as the iframe source, width 100% and a height such as 720 pixels. Add a descriptive title, preview the published page and check that inputs and results fit on mobile.
