NHS Maternity Pay Calculator
This NHS maternity pay calculator estimates statutory maternity pay (SMP) plus the NHS occupational maternity scheme for Agenda for Change staff. It shows the total estimated pay across the maternity period and how that total spreads if it is paid over 9 or 12 months. It is an estimator only, because scheme details vary by contract and trust.

Frequently Asked Questions
What is statutory maternity pay?
Statutory maternity pay is paid for up to 39 weeks: 90% of average weekly earnings for the first 6 weeks, then the lower of 90% of earnings or the statutory flat rate for the next 33 weeks.
What does the NHS occupational scheme add?
For eligible Agenda for Change staff, the occupational scheme typically provides 8 weeks at full pay, 18 weeks at half pay plus statutory maternity pay (capped at full pay), then 13 weeks of statutory pay only, followed by unpaid leave up to 52 weeks.
What do the 9 and 12 month options mean?
Some staff can ask for occupational maternity pay to be spread evenly over a longer period to help with monthly budgeting. The total does not change; only the monthly amount changes.
Is this figure guaranteed?
No. Scheme details vary by contract and trust, and eligibility depends on length of service and earnings. Check NHS official guidance and your trust policy.
