Monthly salary after tax calculator UK 2026/27

Calculate monthly salary after tax

Enter gross monthly salary before deductions. The calculator annualises it by multiplying by 12, then applies the standard 2026/27 rUK Income Tax and employee National Insurance rules. It shows an annual, monthly and weekly estimated net figure with the deduction lines separated.

This answers a different question from monthly salary to hourly pay, which is a gross contract-rate comparison. Use this page when you want an annualised after-tax estimate.

Use gross monthly salary, not bank pay

Enter the contractual monthly pay before Income Tax, employee National Insurance, pension, student loan or other deductions. Choose a student-loan plan only when you have confirmed it, and use the pension input only for a net-pay percentage. Salary sacrifice and relief at source need different treatment.

Why an actual monthly payslip can differ

Payroll works by pay period and can use a personal tax code, cumulative PAYE, variable overtime, bonus payments or a pension method outside this model. The monthly result here is the annual estimate divided by 12. It is useful for comparing offers and budgets, but it is not a payroll promise.

Next step: compare pay formats fairly

Use hourly wage after tax when the offer is quoted by the hour. Use take-home pay when you have an annual gross salary, and use the reverse desired take-home calculator when you are working from a net target.
