How the Nanny vs Daycare Calculator Works

Comparing nanny vs. daycare costs is more complex than it appears. A nanny's hourly wage is just the starting point — as an employer, you must also pay payroll taxes that add approximately 10–12% on top of gross wages. This calculator computes the true cost of a nanny including required employer taxes, then compares it to daycare center and home daycare costs.

The key insight is that nannies become cost-competitive when you have two or more children. Daycare centers charge per child; a nanny's cost covers all your children. With two children in a center at $1,230/month each, you're paying $2,460/mo — comparable to or exceeding a nanny's true cost.

The "With Tax Benefits" tab shows how the Dependent Care FSA applies equally to both options, reducing the net cost of whichever you choose. The FSA only covers the first $5,000 of childcare costs, so its relative impact is smaller for higher-cost options like nannies.

True Nanny Cost Formula

Nanny Gross Annual = Hourly Wage × Hours/Week × Weeks/Year Employer Taxes: FICA (employer share): Gross × 7.65% Federal Unemployment: Min(Gross, $7,000) × 0.6% State Unemployment (est): Gross × 2.0% Workers' Comp (est): Gross × 1.0% True Nanny Cost = Gross + All Employer Taxes True Cost % above wages ≈ 11–13% After FSA: Cost − (FSA Amount × Marginal Tax Rate) FSA also saves FICA on the contributed amount

Important: the "nanny tax" is legally required. Paying a nanny more than $2,700/yr (2024 threshold) triggers household employer obligations. Failing to pay these taxes can result in penalties, back taxes, and complications when the nanny files for unemployment benefits.

Example Calculation

Example: Full-time nanny at $20/hr vs. daycare center, one child

Nanny gross wages (40 hrs × 50 wks)$40,000/yr
Employer FICA (7.65%)$3,060
FUTA + SUTA + workers comp (est.)$1,242
True nanny annual cost$44,302/yr ($3,692/mo)
Daycare center (1 child)$14,760/yr ($1,230/mo)
Daycare center (2 children)$29,520/yr ($2,460/mo)
Nanny covers both children~$44,302–$50,947/yr

With one child, daycare is $29,542/yr cheaper than a nanny. With two children, the gap narrows to roughly $15,000–$21,000/yr. With three children, a nanny can actually be cheaper than three daycare slots.

Frequently Asked Questions

The "nanny tax" refers to household employer payroll taxes you must pay when you hire a nanny, housekeeper, or other household employee. If you pay a household employee $2,700 or more in 2024, you're legally required to: (1) withhold and pay FICA taxes (7.65% from the employee plus 7.65% employer share), (2) pay federal unemployment tax (FUTA), (3) pay state unemployment taxes, and (4) issue a W-2 at year-end. Failure to comply can result in IRS penalties, back taxes with interest, and issues if the employee ever files for unemployment benefits. Many families use payroll services like HomePay or GTM Payroll to manage this.
The crossover point depends on local nanny wages and daycare costs. As a general rule: with one child, daycare centers are almost always cheaper than a nanny. With two children close in age, a nanny becomes cost-competitive (especially if you negotiate a modest "nanny share" rate for the second child). With three children, a nanny is often cheaper than three separate daycare slots. The math also shifts in your favor if you need extended hours, irregular schedules, or sick-day coverage — areas where daycare centers are inflexible.
Yes. The Dependent Care FSA can be used for any qualifying childcare expense, including nannies, daycare centers, home daycare providers, after-school care, and summer day camps. For nannies, the FSA can cover wages paid to a legally employed nanny (with proper W-2 documentation). The annual FSA limit is $5,000 per household ($2,500 if married filing separately). The tax savings equal the FSA contribution multiplied by your combined marginal income tax rate and FICA rate — typically 25–35% total savings on the amount contributed.
A nanny share is an arrangement where two families share one nanny, splitting the cost. Each family typically pays 60–70% of what they'd pay for a solo nanny — so both families save money while the nanny earns more than she would in a single-family arrangement. For example, if a solo nanny earns $20/hr, a nanny share might involve each family paying $14–$15/hr. This creates a win-win: both families spend less than a private nanny, more than daycare, but get more flexibility and personalized care. Finding a nanny share partner is the main challenge — online platforms and local parent groups are the primary resources.
After divorce, childcare costs are typically treated as a child support add-on. Courts generally require each parent to contribute to work-related childcare proportionally to their income. If the custodial parent uses a nanny, the courts will examine whether that cost is "reasonable and necessary" — and may substitute a lower daycare rate if the nanny cost is deemed excessive. Both parents must agree on or the court must approve significant childcare decisions. Changes in childcare costs can also trigger a child support modification request.
