What this means

SMP can run for up to 39 weeks, but Statutory Maternity Leave can run for 52 weeks. That is why a full year off often means a paid period followed by an unpaid tail.

How Statutory Maternity Pay (SMP) and enhanced employer schemes translate to actual take-home over a 39-week leave period.

Emma — £36,000 salary, statutory SMP only

Annual salary£36,000 (£3,000/month gross)
Weekly earnings~£692
SMP eligibilityYes (qualifying weeks met)

The maths:

  1. Weeks 1-6: 90% of average weekly earnings = £692 × 90% = £623/week
  2. Weeks 7-39: lower of (90% of earnings, £194.32) = £194.32/week (2026/27 rate)
  3. Weeks 40-52: unpaid (employer not required to pay)
  4. Total SMP gross: (£623 × 6) + (£194.32 × 33) = £3,738 + £6,413 = £10,151
  5. Tax + NI applies normally to SMP

Result: Emma's take-home over the SMP period is about £9,400 after tax and NI — a sharp drop from her usual take-home of about £2,450 a month. Bridging the gap means using other income or savings, or sharing the leave with a partner. A Lifetime ISA is not a penalty-free source here: withdrawals for anything other than a first home, age 60 or over, or terminal illness carry a 25% government withdrawal charge.

Aisha — £55,000 salary, enhanced employer maternity scheme

Annual salary£55,000 (£4,583/month gross)
Employer scheme6 months full pay, then 3 months SMP at statutory rate
Pension contributions5% of salary, continuing while she is paid

The maths:

  1. Months 1-6: 100% of usual pay = £4,583/month gross (~£3,310 net after tax/NI/pension)
  2. Months 7-9: £194.32/week × 13 weeks = £2,526 gross. That is below the weekly NI threshold, so no NI is due; any Income Tax depends on her tax code and her pay earlier in the tax year
  3. Months 10-12: unpaid leave
  4. Pension contributions continue while she is being paid during maternity leave

Result: Aisha receives about £19,860 net for the six full-pay months (6 × £3,310) plus £2,526 of SMP in months 7-9. On SMP alone, her £55,000 salary would give about £12,100 gross over 39 weeks (6 × £951.92 + 33 × £194.32). Pension contributions carrying on through the paid leave are easy to overlook.

What this page is checking

You can qualify for Statutory Maternity Leave from day one as an employee, but SMP needs the separate earnings and service tests. If you fail SMP, Maternity Allowance may still matter.

Sources and assumptions

This page uses the 2026/27 weekly SMP rate of £194.32 for the main 33-week paid block and the lower earnings limit of £129 a week for eligibility.
