Free calculators for your website

Copy and paste one of these into your site's HTML to add a working UK money calculator. It's free, there's nothing to sign up for, and it updates by itself when tax rates or the energy cap change.

Keep the small "Calculator by Tidy Life Tools" credit line under the calculator.
Optional: to make the height fit exactly, add this script once to the same page: <script>window.addEventListener("message",function(e){if(e.origin==="https://tidylife-tools.pages.dev"&&e.data&&e.data.tlEmbed){var f=document.querySelector('iframe[data-tl="'+e.data.tlEmbed+'"]');if(f)f.style.height=(e.data.height+10)+"px";}});</script>
The calculators work in the visitor's browser. Nothing they type is sent to us, and there are no cookies or tracking.
