Get the Code

Option 1 — Auto-insert (recommended)

Place this script tag anywhere in your HTML. The widget appears automatically below it.

<script src="https://calcdeck.io/widgets/mortgage.js"></script>

Option 2 — Target a specific element

Place an empty div where you want the widget, then add the script.

<div id="calcdeck-mortgage"></div>
<script src="https://calcdeck.io/widgets/mortgage.js"></script>

How It Works

Copy the embed code

One line of JavaScript — no iframes, no external dependencies, no signup.

2

Paste it into your page

Works on WordPress, Squarespace, Wix, and any site that allows custom HTML. The widget auto-sizes to fit your layout.

3

Visitors get instant results

The widget shows the monthly payment, loan amount, and total interest instantly. A "View Full Breakdown" link sends them to CalcDeck for the full amortization schedule, extra payment analysis, and charts — with their inputs pre-filled.

Embed Widget FAQ

Is it really free?
Yes. The widget is free to embed on any website. CalcDeck monetizes through ads on the full calculator page, which visitors reach via the "View Full Breakdown" link.
Does it work on WordPress / Squarespace / Wix?
Yes! On WordPress, use a "Custom HTML" block. On Squarespace, use a "Code Block." On Wix, use the "Embed HTML" app. The script tag works anywhere that allows custom HTML.
Is it fast? Will it slow down my site?
The widget loads asynchronously and renders after your page is interactive. It's under 10KB of JavaScript — lighter than Google Analytics. No layout shift.
Can I customize the colors?
Coming soon! We're adding data-theme attributes for light/dark mode matching and custom brand colors. Stay tuned.
Will this send my visitors away from my site?
The widget itself is fully self-contained — visitors get their monthly payment result right on your page. The "View Full Breakdown" link opens CalcDeck in a new tab, so your visitors never leave your site. They get the detailed schedule they need, and you keep them engaged.
