Free calculator widgets for your website

How it works
- Pick a calculator below and check the live preview.
- Click “Copy code” and paste the snippet into an HTML or “custom code” block in your CMS.
- The widget resizes to your content width (it works from 320px phones to 800px columns).
The terms, in plain English
- The widgets are free for personal and commercial sites. No sign-up and no API key.
- Keep the “Powered by Capitiro” credit and the link under the iframe. That credit is the only thing we ask in return.
- The widgets show no ads. Calculations run in your reader’s browser and we never store their numbers.
- Results are estimates for educational purposes, not financial advice. See our disclaimer.
