snapcalcs is a collection of free UK financial calculators. Built and maintained in the UK, the site covers the everyday money questions people actually ask — adding or removing VAT, converting an hourly rate into an annual salary, working out take-home pay, and more.
What snapcalcs is
Every calculator here is free to use, with no signup, no paywall, and no tracking of the numbers you enter. Figures are kept up to date with the current 2026/27 tax year rates and thresholds as published by HMRC.
The calculators are designed to give you a quick, accurate answer — not a lecture. Where extra context helps (for example, the difference between the National Living Wage and the Real Living Wage), a short explainer sits alongside the result.
Who's behind it
snapcalcs is a small independent project, built and maintained in the UK. There's no investor deck and no venture capital — just a simple goal of making common financial calculations easier to do and harder to get wrong.
