Estimate how much Statutory Maternity Pay (SMP) you could receive based on your average weekly earnings. This calculator uses the common UK SMP structure: 90% of average weekly earnings for the first 6 weeks, then the lower of £194.32 or 90% of weekly earnings for the next 33 weeks. It also shows a full 39-week total and optional monthly-style averages for planning.
This is a planning estimate for employees using the standard SMP formula widely used in UK guidance for 2026/27. Real payroll can differ if pay varies, enhanced employer schemes apply, or eligibility rules are not met.
| Period | Weeks | Weekly pay | Total |
|---|---|---|---|
| Initial higher-rate SMP | — | — | — |
| Standard / capped SMP | — | — | — |
The calculator pays 90% of weekly earnings for the first 6 weeks, then switches to the lower of the standard SMP rate and 90% of weekly earnings for the remaining weeks selected.
