Estimate your maternity pay
Use this pregnancy pay calculator to estimate gross maternity pay over your leave period. It follows a common UK-style structure: first period at 90% of earnings, then statutory-rate weeks.
This is an estimate only and shows gross pay before tax, National Insurance, pension deductions, or policy-specific adjustments.
How this pregnancy pay calculator helps
Planning maternity leave can feel overwhelming. A clear estimate of your pregnancy pay makes it easier to set a household budget, plan savings goals, and discuss options with your employer early. This calculator gives you a practical projection of what you may receive across your leave period.
Instead of trying to manually calculate pay week by week, you can input a few key numbers and get a quick breakdown of:
- Pay during the 90%-of-earnings period
- Pay during statutory-rate weeks
- Potential unpaid weeks if your leave is longer than paid entitlement
- Total gross pay and average monthly amount over the leave period
What the calculator is based on
1) Average weekly earnings
This is your core pay figure before leave. In many maternity pay systems, the first part of paid leave is calculated as a percentage of average earnings. If your income varies, check your payslips and HR guidance so you use a realistic average.
2) Initial percentage-paid period
A common structure is the first six weeks paid at 90% of your average weekly earnings. This calculator lets you adjust the number of weeks in case your contract differs.
3) Statutory-rate period
After the first phase, pay often moves to a lower statutory amount per week (or 90% of earnings if lower). The calculator applies the lower-of rule automatically during this phase.
4) Employer top-up
Some employers provide enhanced maternity pay. If your employer adds a fixed top-up each week, you can include it to get a better estimate.
How to use it accurately
- Use your most up-to-date average weekly earnings figure.
- Check your contract for enhanced maternity pay details.
- Confirm how many weeks of paid leave your employer supports.
- Run multiple scenarios (for example, 26 weeks vs 39 weeks vs 52 weeks).
- Keep a separate buffer for childcare setup costs and emergency expenses.
Example scenario
Suppose your average weekly earnings are £650 and you plan 39 weeks of leave:
- First 6 weeks at 90% of earnings = £585/week
- Next 33 weeks at statutory rate (or 90% if lower)
- Total estimated gross maternity pay is the sum of both phases
With this structure, your income profile changes after week 6. Knowing that shift ahead of time can help you adjust direct debits, savings transfers, and discretionary spending.
Budget planning during maternity leave
Prioritize fixed essentials
Start with rent or mortgage, utilities, food, transport, insurance, and minimum debt payments. Build your base budget around these before lifestyle expenses.
Set a monthly “income bridge” target
If your regular salary is higher than maternity pay, create a bridge fund now. Even a few months of small transfers can reduce stress during lower-income weeks.
Prepare for one-time baby costs
Car seat, sleeping equipment, feeding supplies, and clothing can add up quickly. Make a separate list of one-off purchases and spread them out before leave begins.
Important limitations
This tool is a planning calculator, not a legal determination. Actual amounts can differ due to employer rules, tax treatment, pension contributions, bonus exclusions, and eligibility windows. Always verify final figures with HR, payroll, or an official government maternity pay resource.
Quick FAQ
Does this include tax and National Insurance?
No. Results are gross estimates before deductions.
Can I use this for enhanced maternity packages?
Yes, partially. Add a weekly top-up if your enhancement is fixed. For more complex policies (full pay for X weeks, half pay for Y weeks), use this as a first-pass estimate and confirm with payroll.
What if I plan 52 weeks of leave?
You can enter 52 weeks. If paid entitlement is shorter, the calculator will show unpaid weeks so you can plan cash flow for the full period.
