Mortgage Calculator for Your Site — frequently asked questions
Is it really free?
Yes. The widget is free to embed on any site, personal or commercial, with attribution kept in the widget footer.
Will it slow my page down?
No. The iframe loads lazily and the widget itself is a few kilobytes of HTML, CSS and JavaScript with no external dependencies or trackers.
Is this mortgage calculator for your site free to use?
Yes. Every calculator on the site is free, needs no sign-up, and runs entirely in your browser, so your figures never leave your device.
How accurate is the result?
The maths is exact for the formula shown on the page. Accuracy in the real world depends on your inputs and on assumptions the formula cannot see, so treat the output as a well-grounded estimate rather than a quote.
Can I use it on my phone?
Yes. The page is responsive, weighs a few kilobytes and works offline once loaded, so it behaves the same on a phone as on a desktop.
