How it works
A parental leave budget is a bridge plan for the stretch when a new parent's paycheck shrinks or disappears — measuring exactly how much income vanishes during leave, how much essential spending continues regardless, and therefore how much cash must be stacked before delivery day. In the United States the default scenario is stark: the FMLA protects twelve weeks of job-protected absence but pays zero of them, short-term disability policies typically replace 50–67% of wages for roughly six weeks of physical recovery, and a minority of employers top up the remainder. This calculator walks your specific timeline week by week. Partial-pay weeks contribute their percentage of your usual net income; unpaid weeks contribute nothing; essential expenses continue at full weight the entire time because landlords, insurers and grocery stores do not pause for births. The gap between those two streams is the number that decides everything — at these defaults, twelve partially-paid weeks plus six unpaid ones burn about $6,500 beyond incoming income, which means roughly $1,085 a month set aside across a six-month runway before leave begins. Seeing that figure early transforms it from crisis into line item: trim it via shorter leave, state programs in places like California or New York, or aggressive pre-birth saving.
Formula
Gap = essentials × leave weeks − net pay × partial% × paid weeks | Monthly save = gap ÷ months until leave
Tips
- Confirm short-term disability enrollment before pregnancy — it excludes existing pregnancies.
- Check your state: CA, NY, NJ, RI, WA and others fund paid family leave programs.
- Cut discretionary spend during leave, not savings targets — the gap already assumes austerity.
- Time PTO payout into the leave window; accrued vacation softens unpaid weeks directly.
- Ask HR about sick-leave donation pools and salary-over-time arrangements before assuming unpaid.
Frequently asked questions
- How do people afford unpaid maternity leave?
- Three streams combine: pre-birth savings targeted at the calculated gap, partial wage replacement from short-term disability or state programs, and temporarily reduced spending since essentials alone define the leave budget. Starting six months out, bridging a typical $6,000 gap takes about $1,000 a month — steep but plannable, unlike the same bill arriving as debt.
- How many weeks of unpaid leave can I take?
- FMLA guarantees twelve weeks of job-protected, unpaid leave per year at employers with 50+ staff, if you have worked there twelve months and 1,250 hours. Some states extend paid family leave beyond it, and employer policies sometimes add weeks — always confirm both layers before choosing your timeline.
- Does short-term disability cover maternity leave?
- It typically replaces 50–67% of wages for six weeks of vaginal recovery or eight after a cesarean, minus an elimination period of up to two weeks. Crucially, you must enroll before pregnancy — most group policies treat expectant births as pre-existing conditions, so the coverage decision belongs in last year's open enrollment.
- How much should I save before having a baby?
- Plan for two buckets: the leave gap this calculator sizes — commonly $3,000–$10,000 depending on pay and leave length — plus a general emergency cushion of one to three months of essentials. Combined, many planners target $10,000–$15,000 set aside before delivery, then rebuild afterward on the post-childcare budget.
- Can my partner take paid leave too?
- Increasingly yes: nine states plus DC operate paid family leave programs covering either parent, several large employers offer standalone paternity benefits of 2–8 weeks, and FMLA protects unpaid time for both partners. A second parent taking even two protected weeks measurably shrinks childcare costs in the newborn phase.
