Put a Canadian calculator on your site

What it looks like

This is the live widget, running here exactly as it would on your page:

The code

Paste this wherever you want it. The link underneath is part of the deal and the only thing we ask for.

<iframe src="https://countworthy.com/embed/take-home-pay"
        title="Canadian take-home pay calculator"
        width="100%" height="520" style="border:0"
        loading="lazy"></iframe>
<p><a href="https://countworthy.com/canada/take-home-pay-calculator">Canadian take-home
   pay calculator</a> by Countworthy</p>

Optional: make it resize itself

The widget tells the page how tall it is. Add this once, anywhere on the page, and the frame will fit its content exactly instead of using the fixed height above. Skip it and nothing breaks — you just get a slightly taller box.

<script>
addEventListener("message", function (e) {
  if (e.origin !== "https://countworthy.com") return;
  if (!e.data || e.data.countworthy !== "height") return;
  document.querySelectorAll('iframe[src*="countworthy.com/embed"]')
    .forEach(function (f) { f.height = e.data.height; });
});
</script>

The terms, in full

• It is free, for anyone. Personal blogs, credit unions, accountants, employers, student services, newsrooms. No licence to sign, no invoice, no usage limit.
• Keep the credit link. A visible link to the calculator page, in the page itself rather than only inside the frame. That link is what pays for this.
• We keep it correct. When the Canada Revenue Agency reissues its payroll formulas each January, or a province moves a bracket, the widget updates wherever it is embedded. You do nothing. Our verification process covers the embed exactly as it covers the site.
• Your visitors are not tracked. No analytics, no cookies, no fingerprinting, nothing stored. The figures they type never leave their browser. Nothing about your visitors reaches us, so embedding this does not change what your own privacy policy needs to say about third parties collecting data — because it does not.
• We will not break it. If the widget is ever retired the URL keeps working and redirects to the calculator rather than going blank on your page.
• No ads, ever, inside the frame. If that changes you will be told before it happens, not after.

Want a different calculator, or a version in your own colours?

The take-home pay calculator is the first embed because it is the one most often asked for. CPP timing, TFSA room, RRSP refunds, capital gains and sales tax can all follow. If you want one of those, or the widget matched to your own brand for a credit union or advisory site, email hello@countworthy.com and say which one.

Using the numbers instead of the widget

If you would rather compute the figures yourself, the whole 2026 Canadian tax parameter table is published as open data under CC BY 4.0 — generated from the same engine this widget runs on, so it cannot disagree with what you see above.
