Example 1: Typical UK Values

If you're looking at a common situation, imagine a self‑employed mother who earned £200 per week for at least 13 of the 66 weeks before her baby’s due date, paid Class 2 National Insurance, and has a 26‑week qualifying period.

You’ll qualify for up to 39 weeks.

Because you exceed the £151 minimum, you get the rate.

The maximum entitlement is £7,800, paid to your bank.

Claim within three months of your due date to keep all weeks.

This support lets you concentrate on your baby.

Example 2: Real-Life Case

Many claimants see their earnings fluctuate month to month, making the calculation a bit more complex.

You earned £1,200 in April, £950 in May, £1,400 in June, and £1,050 in July.

To qualify, you must have 13 weeks of earnings at least £30 a week.

Add the eight highest‑earning weeks from those four months – in this case £1,400, £1,200, £1,050, £950, plus the next four weeks at £800 each – giving a total of £7,600.

Common Mistakes UK Users Make

Many users enter their gross earnings instead of the required 13‑week average, inflating the result.

Others assume the calculator automatically accounts for recent job changes, when you must manually adjust dates.

Tips for Better Accuracy

Why does precision matter when calculating your maternity allowance?

You should gather every payslip, P45, and self‑employment record for the 13 weeks before your due date, because missing data skews the weekly average.

Cross‑check your NI contributions on your personal tax account; any gaps mean HMRC will lower your entitlement.

Enter dates exactly as they appear on official documents—don’t round months or weeks, because the calculator uses exact days.

If you’re self‑employed, include all invoices and receipts for the same 13‑week window; HMRC averages gross earnings, not net profit.

Double‑check every entry; even a single digit changes your payout.
