UK Salary Calculator

Your tax code, pay frequency, workplace benefits, pay earlier in the year, bonuses and payroll rounding can all change the amount actually deducted. This calculator gives an annualised estimate rather than a payslip-accurate figure.

The standard Personal Allowance is reduced by £1 for every £2 of adjusted income above £100,000, and reaches zero once income reaches £125,140. The calculator applies this taper automatically.

It depends on the pension arrangement you select. By default this calculator assumes a net pay arrangement: your contribution reduces the income Income Tax is calculated on, but not the income National Insurance is calculated on, which is the most common workplace pension setup after salary sacrifice. Salary sacrifice reduces both your Income Tax and National Insurance income, since the contribution is never treated as your pay. Relief at source, common for personal pensions, does not reduce your Income Tax or National Insurance at the payroll stage at all: your provider claims basic rate relief separately, and higher or additional rate taxpayers must claim the rest through Self Assessment.

No, it is optional. Leave it blank and the calculator assumes the standard 1257L code. If you enter a code, it replaces the calculated Personal Allowance entirely rather than adding to it, since the code itself already encodes any adjustment. Supported codes include standard L codes, BR, D0, D1, 0T, K codes, NT, and the Scottish equivalents (S1257L, SBR, SD0, SD1, SD2, SD3, SK codes, S0T). A W1, M1 or X suffix is accepted but this calculator always shows an annual figure, not a week 1 or month 1 figure.

Weekly figures divide the annual amount by 52. Daily figures divide by 260, the typical number of working days in a year (five days a week across 52 weeks).

Yes. Choose Scotland as your tax region and the calculator applies the Scottish Income Tax bands and rates for the selected year. National Insurance is the same across the UK.
