fin·calc

Embed a free calculator on your website

Add a working mortgage, car-loan, investment or fixed-deposit calculator to your blog or site in one paste. It renders right inside your page — no iframe, no signup, no tracking, and the math runs entirely in the visitor's browser. Free to use; please keep the small “by fin·calc” link.

How it works

Pick a calculator below, copy its code block, and paste it where you want the calculator to appear. Include the one <script> line once per page. You can change the starting numbers and the data-cur / data-locale attributes (e.g. data-cur="GBP" data-locale="en-GB") to localize it.
