UK Calculators
The UK taxes income through PAYE Income Tax bands plus National Insurance, and property buyers face Stamp Duty Land Tax on top of mortgage costs. These free tools use 2026 UK figures to help you estimate take-home pay, stamp duty, mortgage repayments, loan costs and long-term investment growth — all running privately in your browser. Tax tools are UK-specific; the general calculators work anywhere.
