Use this NHS Maternity Pay Calculator to discover the exact breakdown of your enhanced occupational maternity benefits as an NHS employee. The tool uses the latest 2026 statutory rates and “Agenda for Change” terms, allowing you to input your salary annually, monthly, or weekly. It helps you understand how the transition from full pay to half-pay plus SMP affects your household income so you can plan your finances with confidence.

What is the NHS Maternity Pay Calculator?

The NHS Maternity Pay Calculator is a specialised tool designed for employees working under the NHS Agenda for Change (AfC) terms and conditions. While standard UK workers receive Statutory Maternity Pay (SMP), NHS staff are entitled to one of the most generous “Occupational Maternity Pay” (OMP) schemes in the country, provided they meet certain service criteria.

As of April 2026, with the increase of the statutory rate to £194.32, calculating the interaction between your base salary and government top-ups has become more complex. This tool automates that logic, specifically handling the transition from “Full Pay” to “Half Pay plus SMP” and finally to “SMP Only.” It is a vital resource for nurses, doctors, and support staff looking for financial certainty.

How is NHS Occupational Maternity Pay (OMP) calculated?

NHS OMP is paid for a total of 39 weeks. It is based on your “Average Weekly Earnings” (AWE) during the eight weeks leading up to your “qualifying week” (the 15th week before your due date). This includes your basic pay plus any regularly paid supplements, such as high-cost area supplements (London Weighting) or unsocial hours payments.

To calculate your total NHS maternity entitlement (T) over the 39-week period, the NHS Maternity Pay Calculator applies the following logic:

T = (8 wks @ Full Pay) + (18 wks @ 50% Pay + £194.32*) + (13 wks @ £194.32)

*Note: During the half-pay phase, the combined total of half-pay and SMP cannot exceed your original full-pay amount.

Example NHS Maternity Pay Calculation

To understand how the NHS enhanced scheme works with an annual salary input, consider this example for a Band 5 or 6 clinician.

Example: Claire has a gross annual salary of £42,000 and has three years of continuous NHS service.

• Average Weekly Earnings: £807.69 (£42,000 ÷ 52 weeks).
• Weeks 1-8: Full pay of £807.69 per week.
• Weeks 9-26: Half pay (£403.85) + SMP (£194.32) = £598.17 per week.
• Weeks 27-39: SMP only at £194.32 per week.

Total estimated pay: £20,054.40 over 39 weeks. This highlights the massive benefit of the NHS scheme compared to the UK statutory minimum of approximately £9,650 for the same salary.

The Three Phases: From Full Pay to Statutory Rate

• Phase 1 (Weeks 1-8): You receive Full Pay. This is your average weekly earnings before any standard deductions.
• Phase 2 (Weeks 9-26): You receive Half Pay plus Statutory Maternity Pay (SMP). In 2026, the statutory portion is £194.32. If the combination of these two exceeds your full pay, it is capped at your full-pay level.
• Phase 3 (Weeks 27-39): You receive SMP Only (£194.32 per week, or 90% of your earnings if that is lower).

Eligibility Rules: The 12-month continuous service rule

To qualify for the enhanced Occupational Maternity Pay (OMP) shown in our NHS Maternity Pay Calculator, you must meet these criteria by the 11th week before your baby is due:

1. Continuous Service: You must have at least 12 months of continuous service within the NHS. This can be across different Trusts, provided there is no break in service of more than 3 months.
2. Standard SMP Rules: To receive the SMP portion, you must have been with your current Trust for at least 26 weeks and earn above the Lower Earnings Limit (£129 in 2026).

The “Intention to Return” Clause: Avoiding the clawback

A crucial detail of the NHS Agenda for Change contract is the “Intention to Return” requirement. To keep the enhanced Occupational part of your pay (the Full and Half Pay elements), you must agree to return to work for the NHS for at least three months after your leave ends.

If you leave the NHS before this three-month period is up, your Trust has the legal right to “claw back” the occupational portion of your pay. You are always entitled to keep the Statutory (SMP) portion. According to Royal College of Nursing (RCN) guidelines, this is a vital consideration for staff planning career moves (RCN).

NHS OMP vs. Standard Statutory Maternity Pay

If you do not meet the 12-month service requirement, the NHS Maternity Pay Calculator will automatically revert to the standard UK Statutory Maternity Pay (SMP) logic. Under these terms, you receive 90% of your pay for 6 weeks, followed by 33 weeks at the statutory rate (£194.32 in 2026). The NHS enhanced scheme is significantly more valuable, often providing over £10,000 in additional support for clinical staff.

How to use the NHS Maternity Pay Calculator

1. Select salary basis: Choose Annually, Monthly, or Weekly depending on how you are paid.
2. Enter Gross Salary: Input your total pay before deductions. Be sure to include regular enhancements like unsocial hours.
3. Service Check: Tick the box if you have 12 months of continuous NHS service to unlock the enhanced calculation.
4. Review Results: The tool will show your estimated weekly average and the payout for each of the three phases.

Frequently Asked Questions (FAQs)

What if I move to a different NHS Trust during my pregnancy?
As long as there is no break in service of more than three months between the two Trusts, your service is considered continuous for the 12-month OMP rule.

Do I still get my high-cost area supplement (HCAS) while on leave?
Yes. Your OMP is based on your “Average Weekly Earnings,” which includes HCAS (London Weighting).

What happens to my NHS Pension?
You will continue to build up your pension as if you were at work during the paid period of your leave (weeks 1-39). Contributions are based on the actual pay you receive.

Can I take my leave as “Shared Parental Leave”?
Yes. NHS staff can opt into Shared Parental Leave. Many Trusts offer enhanced Shared Parental Pay that mirrors the maternity scheme (NHS Employers).

What if I decide to return part-time?
Returning part-time for at least three months still satisfies the “Intention to Return” clause, preventing a pay clawback.
