Add a mortgage calculator to your Wix site in minutes.
Wix doesn't need a plugin. Add an Embed HTML element to any page and paste a single iframe. White-label, mobile-responsive, and wired for lead capture — no Velo code, no developer.
Paste into a Wix “Embed HTML” element:
<iframe
src="https://yourbrand.calcwidgets.com/embed?widgets=loan-repayment"
width="100%"
height="800"
frameborder="0"
title="Mortgage Calculator">
</iframe>Step-by-step: add a mortgage calculator to Wix
- 1. Sign up for a CalcWidgets trial. Free 14 days — pick your calculators and your subdomain (e.g. yourbrand.calcwidgets.com).
- 2. Brand your calculators. In the dashboard, upload your logo, set your primary color, and configure CTA text and URL (your CRM, Calendly, or contact form).
- 3. Open the Wix Editor. Go to the page where you want the calculator and click Add Elements → Embed Code → Embed HTML (also labelled “Embed a Widget”).
- 4. Paste the iframe. Choose the “Code” option in the HTML Settings panel and paste the snippet above. Drag the element to size it — set a generous height (800px) so the calculator isn't cut off.
- 5. Publish. Hit Publish in the top-right. The calculator loads with your branding, responsive on mobile, lead capture wired. Preview on a phone to confirm the height.
Why the Embed HTML element, not Velo
You can wire calculators into Wix with Velo (Wix's code platform), but you don't need to. The standard Embed HTML element renders the iframe natively, sandboxed from your site theme — so nothing in your Wix design can break the calculator, and the calculator can't break your site.
What you get over a generic Wix calculator
30+ calculators, one embed
Mortgage repayment, HELOC, FHA, VA, DTI, closing cost, property tax, cap rate, BRRRR, 1031, stamp duty, and more — AU, NZ, and US markets. Pick one or a whole tabbed set in a single iframe.
White-label + lead capture
Your colors, logo, and CTA — the calculator reads as part of your Wix site, not a third-party widget. Every calculation can route the visitor to your CRM or booking link.
Embedding on another platform?
CalcWidgets is a standard iframe, so it works anywhere HTML does. See the WordPress and Squarespace guides, or the general calculator widget overview.
