Daycare vs. nanny: the real cost comparison.

For one child, full-time daycare almost always costs less than a full-time nanny. For two children under five, the math flips in many metros. This guide does the full 2026 cost comparison: hourly rates, taxes, benefits, and the break-even points that most families never see calculated honestly.

We compare four common arrangements: center-based daycare, licensed family child care (in-home daycare), a private nanny, a nanny share between two families, and an au pair through a State Department-designated agency. We use real 2026 rates from the most recent Care.com Cost of Care data, Child Care Aware of America state surveys, and the US Department of State au pair program minimums.

The five main options

A quick definition of each, since pricing only makes sense once the structure is clear.

• Center-based daycare. A licensed facility with multiple classrooms, professional teachers, and state-set ratios. Operates 7am to 6pm, weekdays only in most cases.
• Licensed family child care (in-home daycare). A licensed provider caring for a small group of children (usually 4 to 12) inside their own home. Often more flexible hours and lower cost than a center.
• Private nanny. A caregiver employed directly by your family, working in your home. Hours, duties, and pay are negotiated. Family is the legal employer and handles taxes and payroll.
• Nanny share. Two families share one nanny, usually rotating between homes. Each family pays roughly 60 to 70 percent of a solo nanny's rate.
• Au pair. A young adult (18 to 26) from another country who lives with the host family on a J-1 visa, providing up to 45 hours per week of care for a federally regulated stipend.

2026 cost snapshot, one child, full-time

All figures below assume a single child under three, full-time care (45 to 50 hours per week), and an average US metro. Adjust up for major coastal metros and down for smaller markets. We show ranges, not single numbers, because real markets work in ranges.

Sources: Care.com Cost of Care 2025 (national hourly and weekly rates); Child Care Aware of America 2024 state survey for center and family child care figures; US Department of State J-1 program au pair minimum weekly stipend ($195.75 in 2026) plus typical agency, room/board, and education fees.

The real cost of a private nanny

Nanny pricing is the most often miscalculated number in early childhood. Families compare a $25 per hour nanny to a $1,800 per month daycare and decide the nanny is "only" 50 percent more. The actual delta is larger.

A 2026 mid-market private nanny in a US metro charges $22 to $32 per hour for a single child. At $28 per hour and a guaranteed 45-hour workweek, that is $1,260 per week, or $5,460 per month in gross wages. Add 9 to 11 percent in employer-side payroll taxes ($590), and you are at roughly $6,050 per month before any benefits.

Most families do not stop there. A typical legal nanny employment package in 2026 also includes:

• Paid time off. Two to four weeks of PTO per year. That is an additional $2,500 to $5,000 in annual gross.
• Federal holidays. Eight to ten paid holidays. Another $2,000 to $2,800 in annual gross.
• Guaranteed hours. Most nanny contracts pay a guaranteed 40 to 45 hours per week even if you do not need all of them.
• Mileage reimbursement. If the nanny drives a child, the IRS standard mileage rate (67 cents per mile in 2026) is the usual baseline.
• Health insurance contribution. Increasingly common in tight nanny markets like NYC, SF, and Boston, at $200 to $500 per month.

Add all of that, and a "$28 per hour" nanny is actually a $70,000 to $85,000 annual employment cost for a year of full-time care. That is more than the median household income in most US states.

When does a nanny share beat daycare?

A nanny share is the most cost-flexible arrangement available. Two families hire one nanny together, usually paying $20 to $26 per hour combined. Each family's share is typically $11 to $15 per hour, plus payroll taxes and a small premium for the second child.

The math:

• At $24 per hour combined, 45 hours per week, $13 per family per hour: $2,535 per family per month in gross wages.
• Add 10 percent employer payroll: $2,790 per family per month.
• Add prorated PTO and benefits: roughly $3,000 to $3,400 per family per month.

That is comparable to center-based infant care in any of the top 15 US metros and often cheaper. Nanny share also gives families control over hours, curriculum, and sick-day flexibility that no center can match. The catch is the legal complexity: two families share one household employee, and the IRS, your state, and most homeowner's insurance carriers expect both families to be on the books. The National Domestic Workers Alliance publishes sample share agreements.

The au pair case

Au pairs come from the US Department of State J-1 visa program. In 2026, the federally set minimum weekly stipend is $195.75, paid by the host family directly to the au pair. On top of that, host families pay an agency placement fee (usually $9,500 to $11,500 annually) and provide a private bedroom, meals, and a $500 education allowance.

Fully loaded, a typical au pair year in 2026 costs $21,000 to $26,400, all-in. That is competitive with mid-market center-based daycare and dramatically cheaper than a private nanny. The au pair can provide up to 45 hours of care per week and up to 10 hours per day. Schedule flexibility is excellent.

The reasons most families do not take this path: limited to a one-year placement (extendable to two), the au pair lives in the family's home and needs a private bedroom, age-cap limits the caregiver pool, and a learning curve as both sides adjust. Au pairs are also not trained early childhood educators; the program is structured as cultural exchange with childcare, not as professional caregiving.

When daycare is the clear cost winner

For families with one child under three in any metro outside the top five, center-based daycare or licensed family child care will be cheaper than every other option, often by a wide margin. The cost gap typically runs $20,000 to $50,000 per year between center daycare and a private nanny.

Daycare also has tax and subsidy advantages most parents underuse:

• The federal Child and Dependent Care Credit is worth $600 to $1,200 per child against daycare expenses.
• Dependent Care FSAs let working parents pay up to $5,000 per year in daycare costs with pre-tax dollars, saving $1,000 to $1,800 depending on tax bracket.
• Many states offer additional credits or subsidies for licensed daycare that do not apply to private nanny employment.

When two kids change the math

Here is where the standard advice often fails. A single-child family looking at $1,800 per month for daycare versus $5,500 per month for a private nanny does not need a spreadsheet. A two-child family looking at $3,000 to $4,000 per month for two daycare seats versus $6,000 to $7,000 per month for one nanny caring for both children has a real decision.

For two children under five in a major metro, the nanny premium over daycare often shrinks to $1,500 to $3,000 per month, against a long list of nanny advantages (sick day coverage, no drop-off commute, custom schedule). For three children under five, a nanny is frequently the cheaper option, often by a wide margin.

The break-even depends on your specific state's infant ratios, your specific daycare's sibling discount (most centers offer 5 to 15 percent off the second child), and whether your nanny will accept the same rate for two children. The cost calculator handles the multi-child case directly.

A one-page comparison summary

Bottom line

For one child under three, daycare is almost always the cheaper option, by a wide margin and with meaningful tax-favored advantages. For two children, the cost gap narrows; many families in major metros land at near-parity or actually pay less with a nanny share. For three or more young children, a private nanny is often the cheapest and most logistically practical choice.
