Maternity Leave Calculator – Plan Your Time Off
Preparing for a new baby is exciting, but figuring out your exact leave dates, return-to-work day, and potential income impact can feel incredibly stressful—especially when HR policies are written in dense corporate language. Our Maternity Leave Calculator simplifies everything. Enter your due date, your leave entitlement in weeks, and how many weeks you want to take before the birth, and we will instantly calculate your precise leave window and estimated return date.
In the United States, the Family and Medical Leave Act (FMLA) guarantees up to 12 weeks of unpaid, job-protected leave. Many companies now offer additional paid leave on top of this. In the UK, Statutory Maternity Leave is 52 weeks. Knowing your exact dates ahead of time helps you plan finances, childcare arrangements, and handover responsibilities at work well in advance.
Pre-Birth Planning
Taking 1–2 weeks of prenatal leave before your due date gives your body time to rest and allows you to prepare at home without the stress of commuting daily while heavily pregnant.
Financial Planning
Enter your weekly salary to see a rough estimate of take-home income during both paid and unpaid portions of your leave, so you can budget accordingly months in advance.
Return Date Confidence
Knowing your exact return-to-work date early lets you plan childcare arrangements, discuss flexible work options with your manager, and avoid any last-minute surprises.
Maternity Leave FAQs
How much maternity leave am I entitled to in the US?
Under FMLA, eligible employees at companies with 50+ workers are entitled to 12 weeks of unpaid, job-protected leave. Many employers offer additional paid leave beyond this as a benefit.
When should I start my maternity leave?
Most mothers choose to start 1–2 weeks before the due date, though this depends on physical comfort, job demands, and whether your birth arrives early. Talking to your doctor is always advisable.

Extension policies vary by employer and country. In the UK, you can change your return date by giving 8 weeks' notice. In the US, you would need to negotiate directly with HR beyond your FMLA entitlement.
