About these calculators
These tools use current UK thresholds and rates for England and Northern Ireland to estimate Stamp Duty, take-home pay after PAYE and National Insurance, and student loan repayments across the different plan types. Every calculation runs in your browser with no sign-up, and each page explains the assumptions it uses. Figures are estimates for planning — confirm exact amounts with HMRC or your employer.
UK calculators — common questions
How is take-home pay calculated in the UK? Your salary has income tax (through PAYE) and National Insurance deducted. Income tax uses your personal allowance and the basic, higher, and additional bands; NI is charged on earnings above a threshold. Workplace pension contributions usually come out before tax.
How much is Stamp Duty (SDLT)? Stamp Duty Land Tax applies to property purchases in England and Northern Ireland, charged in bands. First-time buyers get relief up to a cap, and additional properties carry a surcharge — the stamp duty calculator handles all three cases.
Which student loan plan am I on? It depends on when and where you studied. Plan 1 and Plan 2 have different repayment thresholds and interest rates, which changes your monthly repayment at the same salary — the student loan calculators compare them side by side.
