Embed our calculators on your website

Real estate agents, lenders, financial bloggers, credit unions and teachers can add any SureCalcs calculator to their own site for free. Embedded calculators are ad-free, mobile-friendly, fast and always up to date — including 2026 tax figures.

How to embed

  1. Pick a calculator below and copy its code.
  2. Paste it into your page’s HTML (in WordPress, use a “Custom HTML” block).
  3. That’s it. The optional script line resizes the frame automatically to fit the calculator.

By embedding, you agree to keep the attribution line visible and unmodified (see our terms).
