A white label mortgage calculator for your own website
Your brand, your domain, no attribution line and no advertising — running on an engine that does full PITI with PMI drop-off, HOA, amortization, and investor metrics most free widgets never touch. One line of HTML, live in minutes, from $29/month.
Not financial advice. Mortgage FV Calculator is a software calculator, not a personal-finance product or advisory service. It computes standard financial functions and displays the results for your convenience. Nothing here constitutes, or is intended to constitute, financial, investment, tax, legal, mortgage, credit, or insurance advice. Always consult a qualified professional before making any financial decision.
What “white label” gets you
The “Powered by” line disappears. There is no advertising, no sponsored lender row, and no lead-resale pixel inside a white-label embed — your visitors stay yours.
PMI that terminates at 80% LTV rather than running forever, HOA and escrow in the total, bi-weekly and extra-principal payoff, and NPV / IRR / future-value for investor audiences.
Hosted and updated by us behind an iframe. No plugin to keep current, no dependency in your build, no security surface added to your site.
Build your embed
Pick a calculator and starting values, then copy the snippet. It works immediately with the attribution line; adding your white-label key from the account page removes it.
Copy this snippet
<iframe id="mfv-mortgage"
src="https://mortgagefvcalculator.com/embed/mortgage?rate=6.75&price=475000&down=47500&term=30&tax=5700&ins=1500&hoa=0&wl=YOUR_WHITE_LABEL_KEY"
style="width:100%;border:0;min-height:640px"
loading="lazy"
title="Mortgage (PITI) calculator"></iframe>
<script>
window.addEventListener("message", function (e) {
if (e.data && e.data.type === "ledger:resize") {
var f = document.getElementById("mfv-mortgage");
if (f) f.style.height = e.data.height + "px";
}
});
</script>Replace YOUR_WHITE_LABEL_KEY with the key from your account page on a Realtor or Business plan. Every listing page can pass its own price, tax, insurance and HOA values as URL parameters.
Who this is for
A rate-and-payment estimator on product pages that matches your brand, shows PMI honestly, and never advertises a competitor next to your own offer.
Per-listing payment estimates that preload each property's price, tax and HOA figures — buyers stay on your listing instead of leaving to a national calculator site.
Skip building and maintaining amortization, PMI and IRR logic. Embed the widget now, or move to the REST API when you need the numbers inside your own UI.
Rental ROI, NPV, IRR and future-value modelling for investor clients — analysis a consumer payment widget cannot produce.

White-label questions
- What does white-label actually remove?
- The “Powered by Mortgage FV Calculator” attribution line inside the widget. The calculator renders on your page, under your colours and your domain's context, with no link back to us and no advertising of any kind.
- Do my visitors' numbers ever leave my site?
- Figures typed into the widget are used to compute a result and are not sold, resold, or shared with lenders. We do not place advertising or lead-resale pixels inside white-label embeds.
- How many websites can one licence cover?
- The Realtor plan covers 1 domain and the Business plan covers up to 10. Larger domain counts are handled as an annual licence — talk to us.
- Can I change the colours and fonts?
- Yes. The embed inherits a neutral theme by default and accepts a colour override; for a pixel-exact match to your brand system we do a fixed-scope custom build.
- Does it work on WordPress, Webflow, Squarespace or Wix?
- Yes. It is a standard iframe with an auto-resize script, so it drops into any HTML or custom-code block. No plugin, no build step, no npm install.
- What happens if I cancel?
- The widget keeps working; the attribution line returns. Nothing breaks on your site and no page starts erroring.
