UK Maternity & Paternity Pay Calculator
Calculate your statutory maternity pay (SMP), paternity pay (SPP), shared parental pay or adoption pay week by week. Updated for 2025 rates.
Statutory Maternity Pay (SMP) in the UK is paid for up to 39 weeks. Here is exactly what you will receive: 90% of your average weekly earnings for the first 6 weeks, then £184.03 per week (or 90% of your earnings if lower) for the remaining 33 weeks. The last 13 weeks of your 52-week entitlement are unpaid.
To qualify for SMP, you need to have worked for your employer continuously for at least 26 weeks by the 15th week before your due date, and you must earn at least £123 per week on average. Paternity pay follows a simpler structure: one or two weeks at £184.03 per week. Shared Parental Pay allows couples to divide up to 50 weeks of leave and 37 weeks of pay between them.
According to the Office for National Statistics, there were approximately 605,000 live births in England and Wales in 2023 (ONS Birth Statistics, 2024). This calculator models SMP, SPP, Shared Parental Pay, and Adoption Pay week by week so you can plan your household finances before your leave starts.
