Open calculatorA UK price, income estimate and National Insurance calculation
Check a price with VAT
The VAT tool adds tax to an exclusive price or extracts it from an inclusive amount. Zero-rated, exempt and out-of-scope options represent different classifications, even when the displayed tax is zero. Review the supply before selecting a treatment. If you need to reconcile a receipt, keep line-level rounding and the mix of supplies in view rather than applying one rate to an unrelated total.
Income tax and National Insurance
Use the income tool for the supported mix of salary, savings and dividends, with the appropriate country and tax-year settings. National Insurance has its own employee, employer and self-employed modes. The income-tax total does not automatically include all those contributions. Compare the same earnings period and read whether an amount belongs to the worker or employer before combining the outputs into a budget.
Select the tax year rather than assuming today
UK tax-year labels cross calendar years. Check the explicit options shown by each form: this directory does not certify a new year of tables or extend the calculator beyond its supported periods. A historical payslip comparison should use its corresponding year, while a current forecast needs current supported rules. Follow the official references when your intended period is not available.
