About UK Calcs

UK Calcs is a collection of free calculators built for people in the UK. Every tool uses current UK rules and rates — tax bands, National Insurance, stamp duty, the energy price cap and so on — and is checked against official sources such as GOV.UK, HMRC and Ofgem.

All calculations run in your browser. Nothing you type is sent to us or stored anywhere.

Accuracy

We work hard to keep every figure correct and up to date, and each page shows when it was last checked. Even so, the results are estimates for guidance only and are not financial, tax or legal advice. For decisions that matter, check with HMRC, your lender or a qualified adviser.

How the site is funded

The site is free to use. It may earn money from advertising and from links to products and services. If you click some links and then buy or sign up, we may receive a commission at no extra cost to you. This never affects the results our calculators give.
