UK take-home pay: gross vs net

Gross pay is not what lands in your bank

Your gross salary is what your contract states before deductions. Take-home pay-also called net pay-is what you receive after Income Tax, National Insurance (NI), workplace pension contributions, student loan repayments, and any other payroll items your employer processes. Benefits such as health insurance or share schemes can also appear on a payslip depending on how they are arranged.

Because thresholds and rates change in government budgets, any calculator-including our UK take-home pay tool-should be treated as a rough check, not a substitute for your P60, P45, HMRC personal tax account, or payroll department.

Income Tax in broad strokes

Most employees pay Income Tax through PAYE, so tax is withheld each pay period. You get a personal allowance on which no tax is due, then slices of income are taxed at progressively higher rates in different bands. Scotland has its own income tax bands and rates for non-savings, non-dividend income; the rest of the UK uses the standard UK bands for those earnings.

If you earn unevenly across the year, have more than one job, or receive benefits in kind, your effective tax can differ from a simple annualisation of one payslip. Bonuses may be taxed heavily in the month they are paid, with possible reconciliation later.

National Insurance

NI contributions fund certain state benefits and the NHS in a broad sense. Employees pay Class 1 NI on earnings above a lower earnings limit, with additional rates above higher thresholds. The exact percentages and thresholds are set by legislation and change over time, which is another reason to verify figures against current HMRC guidance.

Workplace pensions

Auto-enrolment means many employees contribute to a workplace pension unless they opt out. Contributions are usually taken from gross pay, which reduces Income Tax and NI immediately in many arrangements-commonly referred to as relief at source or salary sacrifice depending on setup. The details matter for your marginal tax rate and your employer's policy.

For a simplified look at pension contributions and uplift ideas, see the pension contribution uplift calculator and treat outputs as illustrations only.

Student loan repayments

Plan 1, Plan 2, Plan 4, and Postgraduate Loan plans each have different thresholds and rates. Deductions are typically calculated on earnings above the relevant threshold per pay period. If you are close to a threshold, small changes in gross pay can change deductions noticeably compared with someone on a flat salary.

Sanity-checking your payslip

Start from gross pay, list each deduction line by line, and compare totals to what reaches your bank. If something looks off, payroll or HMRC are the right channels. Use educational tools to explore "what if" questions-like the effect of pension percentage or extra income-rather than to dispute official figures.
