Paycheck calculator › Embed a calculator

Embed a free paycheck or mortgage calculator on your site

Two lines of HTML give your readers a live 2026 calculator — take-home pay for all 50 states, or a full mortgage payment with taxes, insurance and PMI. It runs entirely in the visitor's browser, sets no cookies, shows no ads, and updates automatically when tax tables or rates change. Free for any site; the only condition is the “Powered by paysums.com” line stays visible.

Paycheck calculator

Add ?state=CA&amount=75000&filing=married to the URL to preset it, &theme=dark for dark backgrounds, &accent=0a7cff for your brand colour.

<iframe src="https://paysums.com/widget/paycheck/?state=CA&amount=75000" title="Calculator by paysums.com" width="100%" height="420" style="border:0;max-width:560px" loading="lazy"></iframe>
<script>addEventListener("message",e=>{if(e.data&&e.data.paysums){document.querySelectorAll('iframe[src*="paysums.com/widget/"]').forEach(f=>{if(f.contentWindow===e.source)f.height=e.data.height})}})</script>

Mortgage calculator

Preset with ?price=500000&down=100000&rate=6.5&years=30.

<iframe src="https://paysums.com/widget/mortgage/" title="Calculator by paysums.com" width="100%" height="380" style="border:0;max-width:560px" loading="lazy"></iframe>
<script>addEventListener("message",e=>{if(e.data&&e.data.paysums){document.querySelectorAll('iframe[src*="paysums.com/widget/"]').forEach(f=>{if(f.contentWindow===e.source)f.height=e.data.height})}})</script>

White-label licence: remove the “Powered by” line

Companies that want the calculator under their own brand can license it: add &key=YOUR-KEY to the iframe URL and the attribution line disappears, everything else stays the same (same numbers, same updates, no tracking). $19 a month or $149 a year per domain, cancel any time; the key is delivered instantly by email after checkout.
