Term-time salary calculator
Work out your term-time annual salary and estimated average monthly take-home for 2026/27. Use your employer's paid weeks, including paid holiday.
If the advert already gives your actual reduced salary, use the take-home pay calculator. Do not reduce it again here.
Your payroll confirmation plan
Ask payroll to confirm the advertised full-time salary, full-time and contracted hours, paid weeks including holiday and the full-year denominator. Ask whether pay is equal each month, which pension method applies and what earnings the pension percentage covers.
Keep the advert, written contract and payroll's calculation. Compare the confirmed annual salary and deductions with your payslip. A difference in this estimate alone does not prove underpayment.

What the estimate assumes
Your employer pays equal monthly amounts throughout a complete tax year. We estimate annual income tax and employee National Insurance for a working-age employee in category A, with the standard allowance and any taper. We assume no other income. Monthly figures are annual totals divided by 12, rounded to pennies. The rounded months may not add up to the annual figure.
Payroll can differ because of your tax code, monthly thresholds or payment timing. This is information, not advice. See our calculation method and terms. Pension wealth is separate from spendable take-home. Any extra relief needing a claim, including a later low-earner net-pay payment, is excluded.
For an irregular payment schedule or a mid-year start or leaving date, ask payroll for a payslip estimate and check HMRC's income tax estimate. Other income can change your tax; this calculator cannot combine it.
Why paid weeks need confirmation
Holiday rules depend on your contract. Contractual holiday may exceed the statutory minimum. We do not calculate holiday entitlement, apply 12.07% or decide whether you are a part-year worker. Read the official holiday pay guidance and ask payroll for the paid-weeks factor they use.

Tax, National Insurance and loan rates come from HMRC's 2026/27 employer rates. For relief you may need to claim, check pension tax relief guidance.
A separate worked example
In this illustration only, a £30,000 full-time salary, 37.5 full-time hours, 25 contracted hours, 44 paid weeks and a 52-week denominator give £16,923.08 gross a year. These paid weeks are invented example inputs, not a holiday entitlement or a suggested payroll factor. Your form starts without salary, hours or weeks.
For a simpler hours-only comparison use pro-rata salary. Then compare a confirmed offer with your current pay through the pay and hours planner.
