Maternity leave pay in the US is a puzzle โ not a policy
Unlike every other developed country, the US has no federal paid maternity leave. What you actually get paid during leave depends on your state, your employer, your short-term disability coverage, your PTO balance, and how you sequence them. Replacement rates for the same salary vary from 100% (California tech employer with generous top-up) to 40% (small employer in a non-PFL state). The difference is literally $20,000+ in real income for the same length leave.
This calculator maps out the stacking sequence most employees use โ short-term disability โ state PFL โ employer top-up โ PTO โ unpaid โ and shows the weekly income through the full leave period. The goal is to know your real income gap before baby arrives, not after.
The four benefit buckets
1. Short-term disability (STD) โ 6-8 weeks, 60-70% replacement
STD is private insurance that pays a percentage of your salary during medical disability from childbirth. Most employers offer STD at group rates; some make it opt-in (and it's almost always worth opting in before pregnancy). Typical terms:
- Elimination period: 0-7 days before benefits start
- Replacement rate: 60-70% of gross salary
- Duration: 6 weeks for vaginal birth, 8 weeks for C-section
- Taxability: Taxable if employer paid the premiums; non-taxable if you paid with after-tax dollars
If your employer doesn't offer group STD, individual STD is still available to buy โ but it has a waiting period of 6-12 months before you can use pregnancy-related benefits, which means you need to buy it pre-conception.
2. State Paid Family Leave (PFL)
Paid family leave is a state-run benefit in a growing list of states. As of 2026:
- California: 8 weeks, 70-90% (wage-dependent)
- New York: 12 weeks, 67%
- New Jersey: 12 weeks, 85%
- Rhode Island: 6 weeks, 60%
- Washington: 12 weeks, up to 90%
- Massachusetts: 12 weeks, 80%
- Connecticut: 12 weeks, 95%
- Colorado: 12 weeks, up to 90%
- Oregon: 12 weeks, up to 100% for lower wages
- Others growing: DC, Delaware, Maryland, Minnesota, Maine (phasing in 2026-2028)
PFL is typically stacked after STD โ STD covers the medical disability weeks, then PFL covers bonding weeks. Combined, this can give California families 14-20 weeks of paid leave. Non-PFL states rely only on STD + employer benefits + PTO, which typically tops out at 6-12 paid weeks.
3. Employer parental leave / top-up
Many employers offer their own parental leave benefit in addition to STD and PFL. This can take three forms:
- Full-pay top-up: employer pays the difference between STD/PFL and full salary for a set number of weeks. Common in tech, finance, large professional services.
- Additional paid weeks: e.g., 6 weeks of fully-paid parental leave added to whatever state benefits cover.
- Bonding leave: separate from birth recovery, sometimes available for both parents. Usually 4-12 weeks, may be paid or unpaid.
Ask HR for the full parental leave policy document by week 20 of pregnancy. The verbal summary is often incomplete; the written policy contains the real terms.
4. PTO and unpaid FMLA
PTO (paid time off) is banked vacation/sick time. Some employers require you to use PTO before accessing unpaid FMLA; others let you preserve it. Using PTO replaces 100% of salary, so it's high-value but limited.
FMLA (federal Family and Medical Leave Act) gives you 12 weeks of job-protected unpaid leave. "Unpaid" is literal โ no income while on FMLA unless stacked with STD, PFL, or employer pay. But your job is guaranteed upon return, and your employer must maintain your health insurance (you'll need to continue paying your portion of premiums).
How to stack benefits for maximum leave
The goal is two things simultaneously: maximum income replacement and maximum total weeks off. Here's the stacking sequence most benefits specialists recommend:
- Week 1-6 (vaginal) or 1-8 (C-section): Short-term disability pays 60-70%. Employer top-up brings it to 100% if available. FMLA runs concurrently for job protection.
- Week 7-14 (or 9-16): State PFL begins (if available). Pays 60-90%. Employer bonding leave may run concurrently. FMLA continues.
- Week 15-20+: Use remaining employer parental leave, PTO, then unpaid FMLA to extend time off.
- Beyond FMLA (week 12+): Job protection ends unless your state offers longer protection. Most employers will still hold your job another 4-8 weeks on request, but not guaranteed.
The application paperwork timeline
These benefits don't happen automatically. Plan the paperwork well in advance:
- Week 20 of pregnancy: Request parental leave policy from HR in writing. Confirm STD coverage details.
- Week 28: Complete STD pre-claim forms. Notify employer of planned leave start date (or expected date).
- Week 30: File state PFL pre-claim if your state allows (California lets you pre-file).
- Week 34: Submit FMLA paperwork (12 weeks protection begins when leave starts).
- At delivery: Hospital provides certification paperwork for STD. Fax or submit immediately โ payments start 2-4 weeks after.
- End of STD (6-8 weeks after birth): Transition to PFL. File state claim for bonding leave.
The pre-leave savings target
Even with great benefit stacking, most families see a real income gap during leave. Calculate it precisely:
- Sum all your "during-leave" expected income (STD + PFL + top-up + PTO).
- Compare to normal income over the same number of weeks.
- The difference is your income gap โ the minimum savings buffer.
- Add 2-3 months of normal expenses as a safety net for unexpected costs.
- Deposit in a high-yield savings account, tagged "leave buffer."
Typical total savings target: $15,000-$35,000 depending on household income, benefit structure, and leave length. This is in addition to your normal emergency fund.
Tax treatment varies by benefit source
How your leave income is taxed depends on the benefit source:
- STD โ taxable if employer paid premiums; tax-free if you paid with after-tax dollars
- PFL โ federally taxable; may be state-tax exempt depending on state
- Employer parental leave โ fully taxable as wages
- PTO โ fully taxable as wages
Have extra withholding ready for the non-STD portions. The calculator lets you enter your effective tax rate so the take-home numbers reflect reality.
Returning to work โ and the options you haven't considered
Going back full-time at 12 weeks isn't the only option. Some common arrangements:
- Phased return: 3 days/week for first 4 weeks back, then 4 days, then full-time. Reduces burnout, often possible with a conversation.
- Reduced schedule permanently: 32-hour weeks with proportional pay. Some employers codify this; most will negotiate.
- Remote-first return: return remotely before in-office, gives childcare setup time.
- Unpaid leave extension: many employers grant an extra 4-8 weeks beyond FMLA on request.
