This is a free collection of financial calculators — no sign-up, no app. You enter a few numbers in your browser and see the result instantly. The UK edition currently includes, with more to come:

• Take-Home Pay — net pay after income tax and National Insurance
• Income Tax — tax by band with the tapering personal allowance
• National Insurance — employee Class 1 contributions

All calculations are based on publicly available information from sources such as HMRC and GOV.UK, and reflect the 2026/27 tax year for England, Wales and Northern Ireland. Rates and thresholds change, and Scotland sets its own income tax bands, so results are estimates based on simplified assumptions.

This site does not provide financial, tax or investment advice. Please verify against official sources before making decisions.
