How this salary calculator works
Enter your pay, choose the period and review your tax profile. The result estimates annual deductions first, then divides net pay into equivalent pay periods. It is not a payslip or a tax return.
Tax year and assumptions
2026/27 (6 April 2026–5 April 2027)
- UK resident employee below State Pension age, standard Personal Allowance, category A National Insurance, one job and salary income only. No benefits in kind, marriage allowance, child benefit charge or other income.
- Annual tax liability and annualised National Insurance are estimated. Actual payroll rounds and applies National Insurance and loan thresholds by pay period; uneven pay, tax codes and starting part way through the year can change deductions.
- Pension input models salary sacrifice only: it reduces cash salary before income tax, National Insurance and student loan calculations. Other pension arrangements are not modelled. Minimum-wage eligibility and pension annual-allowance/taper charges require separate checks.
- Student loan figures assume sufficient outstanding loan balance and do not cap the deduction at your remaining debt. One undergraduate plan and an optional postgraduate loan can be combined.

Why can payroll differ?
Tax codes, family circumstances, credits, other income, employer benefits, contribution limits and rounding can change actual pay. Check the stated profile and official sources before using the estimate.
