Maternity pay calculator (SMP)

Statutory Maternity Pay runs for 39 weeks: the first 6 at 90% of your average earnings (no cap), then 33 weeks at £194.32 — or 90% of earnings if that's lower. Enter your pay to see the week-by-week schedule and total.

Weeks 1–6 pay 90% of your average weekly earnings uncapped; weeks 7–39 pay the flat rate or 90%, whichever is lower. Paid through payroll, minus tax and NI.

What the schedule means in practice

SMP is a payroll payment — your employer pays it and reclaims most of it from HMRC, and it arrives like salary with tax and NI deducted. The 39 paid weeks sit inside your 52-week leave entitlement: weeks 40–52 are unpaid unless your employer has an occupational scheme (NHS and teachers both do — their calculators layer the occupational money on top).

To qualify you need 26 weeks of service by the qualifying week and average earnings of at least £129 — the eligibility checker works both out from your due date. Not eligible? You'll likely get Maternity Allowance at the same standard rate.

Common questions

Is SMP paid per week or monthly?
It accrues weekly but lands in your normal payroll cycle — a monthly payslip shows roughly 4.33 weeks of SMP, minus tax and NI like ordinary pay.
Will a pay rise change my SMP?
Yes — a rise effective any time between the start of your averaging period and the end of maternity leave must be reflected in your SMP calculation (the Alabaster rule). Ask payroll to re-run the numbers.
What if I have twins?
SMP is per pregnancy, not per baby — the rates and 39 weeks are unchanged.
Can I work during maternity leave without losing SMP?
Up to 10 keeping-in-touch (KIT) days by agreement, paid as agreed, without ending SMP or leave. An 11th day ends SMP for that week.
Do bonuses count in average weekly earnings?
Everything NI-able paid in the averaging window counts — including a bonus that happens to land there, which can lift the 90% weeks substantially.
