Maternity Leave Calculator

Estimate when statutory maternity leave can start, when it ends, and the key milestones in between, based on the country whose employment law applies. Covers 11 countries with statutory entitlements ranging from 12 weeks (US FMLA) to 52 weeks (UK Statutory Maternity Leave).

The terms maternity leave, parental leave, and paternity leave are used differently across countries. The calculator focuses on the statutory maternity entitlement for the birth parent, since that is the longest and most regulated frame in most jurisdictions. Read the country summary shown with the result for the specific 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.

Statutory entitlements at a glance

The table below summarizes the statutory floor for each of the 11 countries supported by the calculator. Total weeks includes both pre-birth and post-birth leave; paid weeks shows how many of those are wage-replaced by the state or social insurance scheme.

Eligibility and what employers might offer above the floor

Eligibility requirements are the trap. UK SMP requires 26 weeks of continuous service with the same employer ending in the 15th week before the expected week of childbirth. Miss that by a fortnight and you fall back to Maternity Allowance, which pays less. US FMLA needs 12 months of service AND 1,250 hours worked AND an employer with 50+ employees within 75 miles. India needs 80 days of work in the 12 months before delivery. Many employers offer enhanced packages that pay full salary for the statutory window, sometimes extending it by 3 to 6 months at full pay. Check the staff handbook before you plan household finances.

What the calculator does and does not handle

Handles: leave start date based on standard pre-birth window, return date based on total statutory weeks, mid-leave milestones (end of higher-rate pay window, end of job protection). Does not handle: exact pay calculation (depends on salary, employer top-up, prior earnings), early-start scenarios (premature birth often triggers automatic leave start), keeping-in-touch days (10 KIT days under UK SMP, similar in some EU countries), shared parental leave splits between birth parent and partner, multiple-birth extensions (twins/triplets get longer leave in France and the UK), and stillbirth/late-pregnancy-loss provisions, which are governed by separate statutes.

Worked example: UK employee with full SMP entitlement

A full-time employee at a UK consultancy with 3 years of service has an expected due date of May 1, 2026. The earliest she can start Statutory Maternity Leave is the 11th week before the expected week of childbirth, which is the week starting Feb 16, 2026. If she opts to start leave on the due date itself, the calculator shows return- to-work on May 1, 2027 (52 weeks later). Her SMP runs for 39 weeks: first 6 weeks at 90 percent of average earnings (so until June 12, 2026), then 33 weeks at the lower of £172.48 or 90 percent of earnings (until Jan 29, 2027). The remaining 13 weeks are job- protected unpaid leave. If her employer offers an enhanced package of 6 months full pay, the financial profile changes substantially even though the statutory dates do not.

Frequently Asked Questions

What does the calculator actually compute?
It computes the statutory baseline: when leave can start, when leave ends, and key milestones in between (such as the end of UK SMP at 90 percent pay, or the end of FMLA's 12-week protection in the US). It does not compute the exact pay you will receive, since that depends on your salary, employer top-up, length of service, and the specific calculation rules of the paying authority (HMRC, Service Canada, IMSS, etc.).
Why is the US entitlement so much shorter than the UK or Canada?
The US is the only OECD country without paid statutory maternity leave at the federal level. FMLA provides 12 weeks of unpaid, job-protected leave for eligible employees at companies with 50+ employees. State paid family leave programs in California, New York, New Jersey, Massachusetts, Washington, Colorado, Connecticut, Oregon, and Rhode Island provide partial wage replacement on top of FMLA. The calculator shows the federal floor; state entitlements vary widely.
Does this cover paternity leave and adoption leave?
The headline numbers in the calculator are maternity leave statutory entitlements for the birth parent. Paternity leave is typically shorter (UK is 1-2 weeks at statutory rate, France is 28 days, India is unspecified at federal level) and adoption leave often mirrors maternity leave with the leave start date tied to placement rather than birth. Read the country summary for the rule that applies to your situation.
How does the calculator handle eligibility requirements?
It does not. Most countries have minimum service requirements (UK SMP needs 26 weeks of continuous service ending 15 weeks before the due date; US FMLA needs 12 months of service and 1,250 hours; India needs 80 days of work in the prior 12 months). The calculator assumes eligibility. Confirm with your HR team or an employment lawyer before relying on the dates.
How do I plan around employer-specific top-up pay?
Many employers in the UK, US, and Western Europe offer enhanced maternity pay above the statutory minimum (full pay for the first X weeks, then SMP). Some Indian and Singaporean tech employers offer 6 months full pay even though statute provides less. Use the calculator's leave-start and return dates as anchors, then layer your employer's policy on top to compute your specific 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 legal source URL shown next to the result.
