Estimate maternity pay from average weekly earnings and the number of weeks you expect to claim.
Estimate statutory maternity pay from average weekly earnings and maternity weeks. This is the right page when you need a planning figure before leave starts, not a final payroll decision.
A worker with average weekly earnings of £650 and 39 weeks of maternity pay will see a higher first-six-weeks figure than the later weeks, because the statutory scheme pays 90% of earnings initially and then moves to the standard weekly rate.
- Eligibility depends on employment dates and the relevant earnings period.
- The first six weeks are paid differently from the remaining weeks.
- Payroll treatment and any other family payments can change the visible net amount.

Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
This section is intentionally repeated on key tools so the explanation stays near the result instead of being hidden in a separate policy page.
COMMON QUESTIONS
Frequently asked questions
Does this confirm eligibility?
No. Eligibility still depends on the official employment and earnings tests.
Why do the first six weeks look different?
The statutory formula pays 90% of average weekly earnings for that period.
Can this change if my pay period changes?
Yes. Payroll periods and the earnings reference week can affect the result.
