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.

Why a payslip can differ
Why a payslip can differ
Tax code
HMRC tax-code changes, K codes, BR/D codes, or emergency markers can change PAYE deductions.
Cumulative basis
Week 1, Month 1 or non-cumulative payroll can differ from a smooth annual calculator estimate.
Pension method
Relief at source, net pay and salary sacrifice can affect taxable pay and take-home pay differently.
Payroll timing
Bonus, overtime, arrears, refunds, cut-off dates and corrections can all move a single payslip.
PayBreakdown does not decide payroll correctness, lender approval, benefit entitlement or employer compliance, and does not give regulated financial, mortgage, debt, tax, payroll or legal advice.
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.
What this answer does not decide
This is educational guidance on how UK pay and tax work. It does not decide payroll correctness, HMRC treatment, lender approval, benefit entitlement or employment rights, and it is not regulated financial advice. Where a figure matters, check it against your payslip, your HMRC account, or the official guidance linked above.
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.
