Au Pair vs Nanny: Cost, Commitment, and Which Is Better for Your Family
An au pair saves $10,000-$35,000/year compared to a nanny — but requires a spare bedroom and a willingness to host a young adult in your home. Here's the full breakdown.

💰 Au Pair: Full Cost Breakdown
An au pair is a young adult (age 18-26) from another country who lives with your family for 1-2 years as part of a U.S. State Department-regulated cultural exchange program. The total annual cost runs $20,000-$25,000, making it one of the most affordable full-time childcare options for families with multiple children.
- Agency placement fee: $7,000-$9,000 — Paid to a designated sponsor agency (Au Pair in America, Cultural Care, InterExchange, etc.) for matching, screening, visa processing, and ongoing support. This fee covers background checks, childcare experience verification, and a training program before placement
- Weekly stipend: $195.75/week minimum (~$10,200/year) — This is the federally mandated minimum set by the State Department. Some families pay above the minimum to attract stronger candidates, especially in competitive metro areas. The stipend is not subject to Social Security or Medicare taxes because au pairs are on J-1 exchange visitor visas
- Educational allowance: $500/year — You must contribute up to $500 toward the au pair's enrollment in an accredited post-secondary institution. This is a program requirement, not optional
- Room and board: Included in your household costs — You must provide a private bedroom (not shared with your children) and include the au pair in family meals. Estimate $200-400/month in additional grocery and utility costs
- Additional car insurance: $50-150/month — If the au pair will drive your children, you'll need to add them to your auto insurance policy. Rates depend on the au pair's age and driving history
💼 Nanny: Full Cost Breakdown
A nanny is a professional childcare provider you hire as a household employee. They typically have more experience than au pairs and don't live in your home (unless you hire a live-in nanny). Total annual cost ranges from $30,000 to $60,000+.
- Salary: $30,000-$60,000+/year — Part-time nannies (20-25 hrs/week) typically earn $15-25/hour. Full-time nannies (40-50 hrs/week) earn $18-35/hour depending on location, experience, number of children, and additional duties. Nannies in NYC, SF, and D.C. often earn $25-35/hour for one child, $28-40+/hour for two
- Employer taxes: 10-15% on top of salary — If you pay a nanny $2,700+/year (2024 threshold), you must pay employer's share of Social Security (6.2%), Medicare (1.45%), federal unemployment tax (FUTA, 0.6%), and state unemployment tax (varies by state, typically 2-5%). This adds $3,000-$9,000/year to your costs
- Benefits (optional but expected): Most nannies expect 1-2 weeks paid vacation, paid holidays (5-10 days), paid sick days (3-5 days), and sometimes a health insurance stipend ($200-400/month). Guaranteed hours — paying the nanny even when your family is on vacation — is standard in professional nanny employment
- Payroll service: $400-$600/year — Services like HomePay, NannyChex, or SurePayroll handle tax calculations, pay stubs, year-end W-2s, and tax filings for $100-150/quarter. Highly recommended to avoid IRS issues
- No housing required: Unlike au pairs, nannies don't live with you. This means no spare bedroom needed, no shared meals, and full privacy for your family when the nanny goes home
Key Difference: An au pair's hourly rate works out to roughly $4.35/hour ($195.75 ÷ 45 hours), making it dramatically cheaper per hour than a nanny. But au pairs are limited to 45 hours/week and 10 hours/day by federal regulation. If you need more than 45 hours of care, you'll need a second arrangement — or a nanny may be more practical despite the higher cost.
⚖️ Au Pair vs. Nanny: Side-by-Side Comparison
The right choice depends on your family's budget, schedule, living space, and how comfortable you are sharing your home with a live-in caregiver.
- Cost: Au pair wins — $20,000-$25,000/year vs. $30,000-$60,000+ for a nanny. The savings are even greater for families with 2+ children since au pair costs don't increase per child (nanny rates do)
- Experience: Nanny wins — Professional nannies typically have years of childcare experience, CPR/first aid certification, and may have early childhood education degrees. Au pairs have at least 200 hours of childcare experience (a program requirement) but are generally less experienced
- Flexibility: Nanny wins — Nannies can work whatever schedule you agree on (evenings, weekends, overtime at a premium). Au pairs are capped at 45 hours/week, 10 hours/day, with at least 1.5 consecutive days off per week and one full weekend off per month
- Privacy: Nanny wins — A nanny goes home at the end of the day. An au pair lives in your house full-time, using your kitchen, bathroom, and common spaces during off-duty hours
- Cultural enrichment: Au pair wins — Your children gain exposure to another language and culture. Many families report their children developing basic bilingual skills and a broader worldview
- Commitment length: Au pair is fixed — 12-month visa with possible 6-12 month extension. Nannies can be hired long-term with no visa constraints. However, average nanny tenure is 1-2 years before moving on
👥 The Nanny Share Alternative
If a full-time nanny is too expensive and an au pair doesn't fit your lifestyle, a nanny share offers a middle ground that's gaining popularity in metro areas.
- How it works: Two families hire one nanny to care for both families' children together, typically at one family's home. The nanny earns more than a solo-family rate (usually 1.5-1.75x), while each family pays less than they would individually
- Cost per family: If a full-time nanny normally costs $3,500/month, a nanny share might cost each family $2,200-$2,600/month (nanny receives $4,400-$5,200 total). Both families save $900-$1,300/month while the nanny earns a raise
- Tax note: Each family is a separate employer and must handle their own payroll taxes on their share of the nanny's compensation. Both families file Schedule H and issue a W-2 for their portion
- Challenges: Scheduling conflicts, different parenting styles, illness policies (does the nanny still come if one child is sick?), and what happens when one family moves. Write a detailed share agreement covering all contingencies before starting
📋 Nanny Tax Obligations: What You Must Know
Many families accidentally break the law by paying nannies "under the table." The IRS considers a nanny a household employee, not an independent contractor, and the penalties for non-compliance are serious.
- The $2,700 threshold (2024): If you pay any household employee $2,700 or more per year, you must withhold Social Security (6.2%) and Medicare (1.45%) taxes from their pay, and match those amounts from your own pocket — totaling 15.3% of wages split between you and the employee
- Federal unemployment tax (FUTA): If you pay $1,000+ in any calendar quarter, you owe FUTA (0.6% on the first $7,000 of wages). State unemployment taxes vary (typically 2-5% on the first $7,000-$15,000 of wages)
- How to comply: Obtain an EIN (Employer Identification Number) from the IRS — it's free and takes 5 minutes online. Run payroll through a service like HomePay ($100-150/quarter) or DIY with IRS Publication 926. File Schedule H with your personal tax return
- Why it matters: Paying under the table means your nanny can't collect unemployment if you let them go, can't build Social Security credits, and you can't claim the Child and Dependent Care Credit or use your Dependent Care FSA. If caught, you owe back taxes, penalties (up to 100% of unpaid taxes), and interest
🎯 Which Is Right for Your Family?
Neither option is universally better — it depends on your specific situation. Here's a quick decision framework.
- Choose an au pair if: You have a spare private bedroom, you want to save significantly on childcare costs, you value cultural exchange, you have multiple children (cost doesn't increase per child), and you're comfortable with a live-in arrangement for 12-24 months
- Choose a nanny if: You need more than 45 hours/week of care, you want a highly experienced caregiver, you value privacy in your home, you need flexibility for irregular schedules (evenings, weekends), or you don't have a spare bedroom
- Choose a nanny share if: You want individual attention for your child without the full cost of a solo nanny, you know another family with a child of similar age, and you're organized enough to manage a shared employment arrangement
- Consider daycare if: Your budget is tight (daycare is often cheaper than a nanny), you want socialization from an early age, and you prefer an institutional setting with regulatory oversight, backup staffing, and structured curriculum
Pro Tip: If you're leaning toward an au pair, start the process 3-4 months before you need care. Agency matching, visa processing, and travel arrangements take time. For a nanny, begin interviewing 6-8 weeks before your start date. In both cases, arrange a trial period — 2 weeks for a nanny, the first month for an au pair — to make sure the fit works before fully committing.
