Maternity Leave Calculator

Last reviewed: October 14, 2026

Estimate when statutory maternity leave can start, when it ends, and the key milestones in between, based on the country whose employment law applies. The calculator covers 11 countries. The shortest period it counts is 12 weeks (the US Family and Medical Leave Act and Mexico's Ley Federal del Trabajo); the longest are 52 weeks (UK Statutory Maternity Leave) and 12 months (unpaid parental leave under Australia's Fair Work Act).

The terms maternity leave, parental leave and paternity leave are used differently across countries. The calculator models the statutory maternity entitlement of the birth parent. Read the country summary shown with the result for the rule that applies.

Important: this is a planning estimate, not legal advice

Leave entitlements vary by employer, contract, eligibility (length of service, employee status, hours worked), industry collective agreements, and the specific facts of each pregnancy. The calculator shows the statutory baseline only. Always confirm your personal entitlement with your HR department, employment contract, or an employment lawyer before relying on the dates for financial or career planning.

Summary: The Family and Medical Leave Act gives an eligible employee a total of 12 workweeks of leave in a 12-month period for the birth of a child and to care for the newborn (29 CFR 825.200), and that leave is generally unpaid (825.207). An eligible employee has 12 months of employment, 1,250 hours of service in the previous 12 months and a worksite with 50 or more employees within 75 miles (825.110). An expectant mother may also take FMLA leave before the birth for prenatal care or if her condition makes her unable to work, and the entitlement to leave for a birth ends 12 months after the birth (825.120). The dates count the 12 weeks as one block from the date entered.

Reference: Family and Medical Leave Act of 1993; 29 CFR 825.110, 825.120, 825.200 and 825.207.

Statutory entitlements at a glance

The table below gives, for each of the 11 countries the calculator supports, the length of the period it counts and the statutory pay or benefit inside that period. Australia's pay is counted in days and depends on the child's date of birth; the row shows the figure for a birth on the date this page was last updated. Each country's sources are shown with its result in the calculator and listed at the end of this page.

Eligibility and what employers might offer above the floor

Eligibility is where plans most often go wrong. In the UK, Statutory Maternity Pay needs at least 26 weeks of continuous employment with the same employer continuing into the qualifying week, the 15th week before the expected week of childbirth, and average earnings of at least £129 a week; an employee who does not qualify may be eligible for Maternity Allowance instead. The US Family and Medical Leave Act covers an employee with at least 12 months of service and 1,250 hours in the 12 months before the leave, at a worksite with 50 or more employees within 75 miles. In India, the Code on Social Security, 2020 requires at least 80 days of work for the employer in the 12 months before the expected delivery. An employer's own policy can be more generous than any of these, so check it before planning household finances.

What the calculator does and does not handle

Handles: the start date from each law's period before the birth, the return date from the length of the period, and the milestones in between, such as the end of a higher pay rate or of a benefit period. Does not handle: the exact pay, which depends on salary, employer top-up and prior earnings; early births (in the UK, leave starts the day after the birth if the baby arrives early); shared parental leave split between the birth parent and a partner; longer leave for multiple births (in France, 34 weeks for twins and 46 for three or more); and the separate rules on pregnancy loss.

Worked example: UK employee with full SMP entitlement

A full-time employee with three years of service at a UK consultancy has a due date of Friday 1 May 2026, so her expected week of childbirth starts on Sunday 26 April. The earliest she can start Statutory Maternity Leave is 11 weeks before that week, in the week beginning Sunday 8 February 2026. If she starts her leave on the due date, the 52 weeks run to Thursday 29 April 2027 and she returns on Friday 30 April 2027. Statutory Maternity Pay covers 39 of those weeks: 90 percent of her average weekly earnings for the first 6, to 11 June 2026, then £194.32 a week or 90 percent of her earnings, whichever is lower, for 33 weeks, to 28 January 2027. The last 13 weeks of leave are unpaid. An employer that pays more changes the money but not these statutory dates.

Frequently Asked Questions

What does the calculator actually compute?
It computes the statutory baseline: when leave can start, when it ends and the milestones in between, such as the end of the 90 percent weeks of UK Statutory Maternity Pay or the end of the 12 weeks of FMLA leave in the US. It does not compute the pay itself, which depends on your salary, any employer top-up, your length of service and the paying scheme's own rules.
Why is the US entitlement so much shorter than the UK's?
The federal Family and Medical Leave Act gives an eligible employee up to 12 workweeks of leave in a 12-month period for the birth of a child and to care for the newborn, and its regulations state that FMLA leave is generally unpaid. UK Statutory Maternity Leave is 52 weeks, 39 of them with Statutory Maternity Pay. The calculator shows the federal floor for the US; state law can add to it, so check the rules where you work.
Does this cover paternity leave and adoption leave?
The headline numbers are the birth parent's statutory maternity entitlement in each country. Paternity leave and adoption leave follow separate rules that the calculator does not model; where a country's maternity law itself covers adoption, the country summary says so, as India's does. Read the summary for the country you select before relying on the dates.
How does the calculator handle eligibility requirements?
It does not. Several countries set conditions: UK Statutory Maternity Pay needs 26 weeks of continuous employment continuing into the 15th week before the expected week of childbirth; the FMLA needs 12 months of service and 1,250 hours; India needs 80 days of work in the 12 months before the expected delivery. The calculator assumes eligibility, so confirm yours with your employer or an adviser before relying on the dates.
How do I plan around employer-specific top-up pay?
The calculator works from statutory entitlements only. An employer's own policy can pay more, or for longer, than the law requires. Use the calculator's leave-start and return dates as anchors, then apply your employer's policy on top of them to work out your own pay schedule.
Can I share the result with my HR team or partner?
Yes. The URL updates as you change the country, date type, or date. Copy the URL into an email, Slack, or a shared planning document. The link reproduces the same calculation when opened later, which is useful when the recipient wants to verify the dates against the sources shown with the result.
