PayBreakdown

How is take-home pay calculated?

UK take-home pay is usually gross salary minus PAYE income tax, National Insurance, pension contributions, and student loan repayments.

The short answer

A 2026/27 UK salary estimate normally starts with gross pay, applies any pension treatment, calculates taxable pay, then deducts PAYE Income Tax, National Insurance, student loans, and other entered deductions to reach take-home pay.

The broad calculation order

A salary estimate is not just one tax percentage. It builds the result from pay, allowances, payroll deductions and the selected tax-year rules.

  • Start with gross pay for the year or period.
  • Apply pension treatment where relevant.
  • Work out taxable pay and PAYE Income Tax from the tax code, region and tax year.
  • Calculate employee National Insurance under UK-wide rules.
  • Apply student loan, postgraduate loan and any entered deductions separately.

Why a real payslip can differ

A calculator usually smooths an annual figure, while payroll works from the actual pay period and employer records.

  • Tax code or emergency basis.
  • Pension method: relief at source, net pay or salary sacrifice.
  • Bonus, overtime, arrears or payroll corrections.
  • Student-loan plan, postgraduate loan status or start/stop notices.

Frequently asked questions

Does pension come before or after tax?

It depends on the pension method. Net pay, relief at source, and salary sacrifice can affect taxable pay and take-home pay differently.

Why do calculators ask for tax code and region?

Tax code affects the personal allowance, and Scotland uses different income tax bands from England, Wales, and Northern Ireland.
