Maternity pay calculator
See your household income across maternity, paternity or shared parental leave — statutory pay, any employer enhancement and a partner's income — month by month, so you can see where any gap falls. Statutory pay comes from the current rates; the rest are your own figures. An illustration to plan with, not a payslip.
Answer a few quick questions and we'll picture your statutory pay, any employer top-up you tell us about, and your household income through the leave. It's an illustration on your own numbers — it clears when you leave the page.
This calculator, the result and the breakdown are free for everyone, no account needed.

How it works
- 1Tell it whether you're the birth parent or the partner, and your employment type, so it picks the right pay route (statutory maternity, paternity or shared parental pay).
- 2Enter your gross annual pay and answer the eligibility questions as best you can — they're asked, never tested, so nothing is decided for you.
- 3Add any employer top-up and a partner's monthly income if you'd like the fuller household picture — these are your own illustrative figures.
- 4The calculator lays out the income month by month across the leave and shows the total drop against earning normally, so you can plan for the gap.
Worked example
A birth parent, employed, on £30,000 a year, expecting to meet the statutory maternity pay rules, taking 52 weeks of leave, with no employer top-up entered. The calculator lays out the statutory maternity pay month by month and shows the total income drop across the leave compared with earning normally.
Statutory pay rates are set by the government and change each April, and average weekly earnings use a set period we can't see — so it's a rough picture. Any employer top-up is your own contract, not a statutory figure. GOV.UK confirms your amount and dates.
Frequently asked questions
How much is statutory maternity pay?
Statutory maternity pay is a higher rate for the first weeks, then a flat weekly rate, up to 39 weeks. The exact figures are set by the government and change each April. Enter your details and the calculator pictures the pay month by month.
How long is maternity pay paid for?
Statutory maternity pay can run for up to 39 weeks, and leave for up to 52 weeks — so the last stretch is often unpaid. The calculator shows where any unpaid tail falls so you can plan for it.
Does the calculator include an employer top-up?
It can. Enhanced maternity pay is your employer's own scheme, not a statutory figure, so you enter it yourself and it's shown as illustrative. Your employer's policy is where to confirm exactly what you'd get.
What if I'm self-employed?
Self-employed parents usually can't get statutory maternity pay but may be able to claim Maternity Allowance instead, which works differently. The calculator flags this rather than estimating it — GOV.UK is the place to check Maternity Allowance.
