Embed a free calculator on your website

Add any GlobalCalc tool to your site in under a minute — free, no sign-up, always up to date

Run a finance blog, mortgage brokerage, accountancy, or property site? Embed any of our calculators straight into your pages. The tool stays accurate automatically — we maintain the tax brackets, rates and thresholds — it works on mobile, runs entirely in the visitor’s browser, and costs nothing.

How to embed a calculator

  1. Open the calculator you want from the lists below.
  2. Find “📋 Embed this calculator (free)” near the bottom of the page and expand it.
  3. Copy the snippet and paste it into your page’s HTML where you want the calculator to appear.

That’s it — the calculator appears inside a tidy frame with a small “by GlobalCalc” link beneath it.

Why embed instead of building your own

  • Always current — when tax rates or thresholds change, your embed updates automatically. No annual maintenance.
  • Accurate & tested — each calculator is checked against official figures (IRS, HMRC, ATO, Bank of England, the Fed and more).
  • Fast & private — it runs in the visitor’s browser; no data is collected and nothing slows your page down.
  • Free — the only condition is keeping the visible “by GlobalCalc” credit link.

Usage & licence

Embedding is free for any website. Please keep the “by GlobalCalc” attribution link visible and don’t alter the calculator’s results. The calculators are provided for general information, not financial advice. If you’d like a custom or white-label embed, get in touch.
