Embed our mortgage calculator on your site
Free, mobile-friendly, no API keys or JavaScript dependencies. Just drop one line of HTML into any blog, real-estate page, or financial-planning post and your readers can run their own numbers.
Embed code
Copy this snippet and paste it anywhere HTML is allowed (WordPress custom-HTML block, Webflow embed, Ghost HTML card, Substack subscribers-only post, etc.). Adjust height to taste — 900px is a comfortable default.
<iframe
src="https://pitipaymentcalc.com/embed/mortgage-calculator"
width="100%"
height="900"
frameborder="0"
loading="lazy"
title="Mortgage Calculator by HomePaymentHQ"
style="border: 1px solid #e2e8f0; border-radius: 12px; max-width: 100%;"
></iframe>Live preview
This is exactly what your readers will see — fully interactive, all calculations run in their browser, no server round-trips.
License & attribution
The widget is free for personal and commercial use. The only requirement is that the “Powered by HomePaymentHQ” attribution stays visible — it's already built into the iframe footer and we ask that you not hide it with CSS.
That attribution link is also a backlink to our site, which helps us keep the calculator free and ad-supported. Thanks for embedding!
Customizing the height
The default height="900" shows the inputs, payment summary, and a few rows of the amortization schedule comfortably. If you want to show the full schedule by default, increase to 1400+. If you only want the inputs and summary, 650 works on most layouts.
Mobile responsiveness
The iframe is set to width="100%", so it will fill any container you put it in. The calculator itself is mobile-first and reflows down to ~320px wide.
Other calculators
Our refinance break-even, affordability, and ARM-vs-fixed calculators are also embeddable. Replace/embed/mortgage-calculator with one of:
/embed/mortgage-calculator(this one)- (more calculators coming as embed surfaces — email hello@pitipaymentcalc.com if you'd like a specific one prioritized)
