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.

Build your embed code

Pick a market and a calculator — copy the snippet, paste it into your page’s HTML, done. It works in WordPress (Custom HTML block), Webflow, Squarespace, Wix, Ghost, or any hand-coded site.

Live preview (this is exactly what your visitors see)

Every snippet includes one small line under the calculator: “Powered by GlobalCalc →”. Keeping it visible is the only condition of the free licence. It’s a plain, honest credit — not keyword-stuffed — and it links to the calculator’s own page so your readers can open the full version. In return you get a professional, always-current tool on your page at zero cost and zero maintenance.

Optional: make it resize automatically

By default the frame is a fixed height with its own scroll — perfectly usable. If you’d like it to grow and shrink to fit the calculator exactly (no inner scrollbar), add this one line anywhere on the page. It only listens to GlobalCalc and is safe with any number of embeds:

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).
  • Browser-based — calculator arithmetic runs in the visitor’s browser, and no GlobalCalc account is required.
  • Free — the only condition is keeping the visible “Powered by GlobalCalc” credit link.

Usage & licence

Embedding is free for any website. Please keep the “Powered 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.
