UK Salary After Tax Calculator

What this calculator does

This calculator estimates your approximate take-home pay in the United Kingdom by applying the current UK income tax bands and the employee National Insurance contributions to a gross salary. It outputs both annual and monthly net pay figures so you can quickly compare gross offers, plan budgets, or evaluate the impact of pay adjustments.

Who should use this calculator?

Use this tool if you are a UK employee, job candidate, freelancer paid under PAYE, or anyone who wants a clear estimate of net pay after tax and National Insurance. It is useful for budgeting, comparing job offers, and estimating take-home salary before pension or pre-tax deductions.

How this calculator works

1. We start with your gross annual salary (or convert monthly pay to annual).
2. Personal allowance (if applicable) is subtracted to determine taxable income.
3. Income tax rates are applied across the relevant bands to compute tax owed.
4. Employee National Insurance contributions are calculated on qualifying earnings.
5. The calculator subtracts tax and NI to show your estimated net annual and monthly pay.

How to interpret your result

The displayed net pay is an estimate. Annual net pay shows take-home pay for the year after basic income tax and employee National Insurance. Monthly figures divide the annual net by 12 for convenience. Do not treat these values as official payroll figures — they do not include employer pension contributions, employee pension deductions, or other employer-specific adjustments.

Example

For example, a gross salary of £40,000 (2025 bands) with a standard personal allowance might result in taxable income after allowance; applying the basic and higher-rate bands plus employee National Insurance typically yields an annual net pay in the low £30,000s and a monthly net around £2,600–£2,800. Use the form above to enter exact values for a personalised estimate.
