The Maternity and Paternity Leave Income Calculator helps new and expecting parents estimate their take-home income during parental leave, which is one of the most financially complex periods in a family's life. The United States is the only high-income country in the world without a federal paid parental leave law, leaving income replacement during parental leave to a patchwork of federal law (FMLA), state paid family leave programs, employer policies, and short-term disability insurance. The federal Family and Medical Leave Act (FMLA), administered by the Department of Labor (DOL), provides up to 12 weeks of unpaid, job-protected leave per year for eligible employees at companies with 50+ employees, for qualifying reasons including childbirth and bonding with a newborn. However, 'unpaid' is key — FMLA guarantees the job, not the paycheck. As of 2024, 13 states plus Washington D.C. have enacted paid family leave (PFL) programs: California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, Oregon, Rhode Island, and Washington. These programs replace 60–90% of weekly wages up to a state maximum for 6–20 weeks. Many employers offer their own paid parental leave policies above and beyond state requirements, ranging from 2 weeks to 6 months at full pay. Short-term disability insurance (STD) is another income source — typically replacing 60–70% of salary for the medically disabled period of pregnancy and recovery (6–8 weeks for vaginal birth, 8–10 weeks for C-section). Understanding the interaction between FMLA, state PFL, employer PFL, and STD insurance is essential to accurately projecting income during leave.
Total Leave Income = (STD Weeks × STD Weekly Benefit) + (State PFL Weeks × State Weekly Benefit) + (Employer PFL Weeks × Full Pay) State Weekly Benefit = MIN(Weekly Wage × Replacement Rate, State Maximum Weekly Benefit) Net Pay During Leave = Gross Leave Pay − Federal Income Tax − State Income Tax − FICA (if applicable) FMLA Gap = Weeks of Unpaid Leave × Normal Weekly Take-Home Pay
- 1Step 1: Determine FMLA eligibility. You must work for a covered employer (50+ employees within 75 miles), have worked 12 months and 1,250 hours in the past year. FMLA provides 12 weeks job protection (unpaid unless employer or state provides pay).
- 2Step 2: Check your state's paid family leave program. If you're in a state with PFL, determine your weekly benefit amount (typically your weekly wage × state replacement rate, capped at the state maximum).
- 3Step 3: Review your employer's paid leave policy. Many employers now offer 2–20 weeks at full or partial pay. Some require you to exhaust PTO/vacation first.
- 4Step 4: Determine STD insurance status. If enrolled before pregnancy, STD typically covers 6–8 weeks for vaginal birth and 8–10 weeks for C-section at 60–70% of salary (or as specified in the policy).
- 5Step 5: Map out the leave weeks. Typically: STD weeks run first (weeks 1–8/10), followed by state PFL weeks, with employer PFL layered in according to company policy. Weeks beyond these benefits are unpaid FMLA weeks.
- 6Step 6: Calculate net income for each phase. Apply appropriate tax treatment. STD benefits are taxable; state PFL benefits are taxable federally and sometimes at the state level; employer paid leave is taxable.
- 7Step 7: Calculate the total income gap — the difference between your normal take-home pay and your leave income — so you can build savings to cover it before the baby arrives.
A California employee with 8 weeks of employer paid leave followed by 8 weeks of California's SDI/PFL program receives good income replacement. The state program pays 70% of wages (capped), providing meaningful income during the bonding period.
Without a state PFL program, a Texas employee with only 6 weeks of employer PFL and 8 total STD weeks faces 4 weeks of unpaid leave. This highlights the importance of building 4–6 weeks of savings before birth if taking a 12-week leave in states without PFL.
New York's PFL is one of the most generous in the country, providing up to 12 weeks of job-protected paid leave for bonding regardless of birth method or parent gender. Non-birthing parents access the same benefit as birthing parents.
Employees at companies under 50 employees are not protected by federal FMLA and have no job guarantee during leave. In states without PFL, the only income replacement is employer goodwill. Building 8–12 weeks of savings before birth is critical for this situation.
Professionals in finance and investment use Maternity Leave Pay as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Maternity Leave Pay into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Maternity Leave Pay to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Maternity Leave Pay for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.
Self-employed individuals: Are not eligible for FMLA or state PFL programs in most states.
California is an exception — self-employed individuals can opt into the CA SDI/PFL program. Independent contractors are generally not covered.
Federal employees: Covered by the Federal Employee Paid Leave Act (FEPLA) — up
Federal employees: Covered by the Federal Employee Paid Leave Act (FEPLA) — up to 12 weeks paid parental leave for qualifying births, adoptions, and foster placements as of October 2020.

Military families: The Military Parental Leave Program was expanded in 2023 — service members now receive 12 weeks of paid parental leave for primary caregiver and 12 weeks for secondary caregiver following a birth.
Adoption and foster care: FMLA and most state PFL programs cover adoption and foster placement leave, not just birth.
Some employer policies exclude adoption — check the specific policy language.

What is the difference between FMLA and paid family leave?
FMLA (federal law) provides up to 12 weeks of unpaid, job-protected leave for eligible employees. Paid family leave (PFL) refers to state programs or employer policies that provide income replacement during that leave. FMLA guarantees your job won't be lost; PFL guarantees some of your paycheck. Many states run both simultaneously — FMLA protects the job while state PFL provides income replacement.
Which states have paid family leave programs?
As of 2024: California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, Oregon, Rhode Island, Washington, and Washington D.C. have enacted paid family leave programs. Several more states have passed legislation with phased implementation dates. The National Conference of State Legislatures (NCSL) maintains the most current list.
Is short-term disability the same as maternity leave?
No, but STD insurance is commonly used to fund part of maternity leave. STD covers the period during which the birthing parent is medically disabled — typically 6 weeks for vaginal birth and 8 weeks for C-section. After the medical recovery period ends, bonding time is covered by state PFL or employer PFL, not STD. STD does not cover paternity leave (non-birthing parent).
Can I get denied FMLA leave?
FMLA leave cannot be denied for eligible employees at covered employers for qualifying reasons. However, you can be denied if: you've already used your 12 weeks in the past 12 months; you haven't met the 12-month or 1,250-hour requirements; your employer has fewer than 50 employees; or you're not within 75 miles of 50 employees. Some highly-paid employees may be excluded from FMLA restoration rights (key employee exception).
What is the PUMP Act and how does it affect nursing mothers?
The Providing Urgent Maternal Protections for Nursing Mothers Act (PUMP Act), signed into law in December 2022, extends the right to reasonable break time and a private space (not a bathroom) for breastfeeding/pumping to nearly all employees covered by the Fair Labor Standards Act. This applies for 2 years after childbirth. Employers with fewer than 50 employees may be exempt if providing break time would cause undue hardship.
Can both parents take FMLA leave at the same time?
Yes, both parents can take FMLA simultaneously if both are eligible. However, if both parents work for the same employer, some limitations may apply regarding the combined total leave. Each parent is individually entitled to up to 12 weeks of FMLA leave for the birth or adoption of a child.
How do I apply for state paid family leave benefits?
Applications are made directly to your state's paid family leave administrator, typically a state labor or insurance department. In California, file through SDI Online with the Employment Development Department. In New York, file with your employer's PFL insurance carrier. Most applications require documentation of the birth, employer information, and banking details for direct deposit of benefits.
Are paid family leave benefits taxable?
Generally yes. State paid family leave benefits are subject to federal income tax. State income tax treatment varies — some states exempt their own PFL benefits, others tax them. Short-term disability insurance benefits are taxable if premiums were paid by the employer pre-tax. Consult a tax professional about your specific situation, particularly if you receive benefits from multiple sources during the same tax year.
プロのヒント
Before taking parental leave, meet with your HR department to get a written breakdown of exactly which benefits will be available, in what order, and for how many weeks. Then calculate your net income for each phase of leave and compare to your monthly expenses. A written 'leave income map' prevents financial surprises and helps you know exactly when to start building a savings buffer.

The United States is the only OECD (Organisation for Economic Co-operation and Development) member country — and one of only six countries in the entire world — that does not guarantee paid maternity leave at the national level. The six nations are the U.S., Papua New Guinea, Palau, Nauru, Tonga, and the Marshall Islands.
