Daycare vs Nanny: A Real Cost Comparison by County
Choosing between daycare and a nanny is one of the biggest financial decisions new parents face. Using DOL childcare pricing data across 3,224 counties and Bureau of Labor Statistics wage data for childcare workers, we compare the true costs of each option including hidden expenses most families overlook.
The Headline Numbers
For a single infant, center-based daycare is almost always cheaper than hiring a private nanny. The DOL data shows median weekly center-based infant care ranging from $150 in the most affordable counties to over $450 in expensive metro areas. A full-time nanny in those same areas costs $600-$1,000 per week or more. In New York, the gap is especially pronounced, with center care averaging $350/week while nannies command $700-$900/week in the metro area.
However, this calculus changes with multiple children. Daycare charges per child, so two children in center-based care costs roughly double. A nanny caring for two children typically charges only 10-20% more than for one. For a family with two children under age 5, a nanny can be the same price or even cheaper than two daycare spots.
True Cost of a Nanny: Beyond the Hourly Rate
When families compare nanny costs to daycare, they often look at the gross salary and stop there. But hiring a nanny makes you a household employer, with significant additional obligations. As a household employer, you must pay the employer share of FICA taxes (7.65% of wages), federal unemployment tax (FUTA), and state unemployment tax. Most states also require workers' compensation insurance.
Industry norms also include two weeks of paid vacation, sick days, and potentially a year-end bonus. When you add payroll taxes, insurance, paid time off, and the cost of backup care when your nanny is sick or on vacation, the true cost of a nanny is typically 20-30% higher than the gross salary.
A nanny earning $700/week gross actually costs approximately $860-$910/week when all employer costs are included. Over a full year, that is $44,700-$47,300 compared to a quoted salary of $36,400. The Department of Labor provides guidance on wage and hour requirements for household employees.
True Cost of Daycare: What the Tuition Doesn't Cover
Daycare costs also have hidden components. Registration fees ($50-$200/year), supply fees, activity fees, and late pickup charges can add 5-10% to the base tuition. Many centers require families to pay for holidays and sick days when the center is open but the child is absent. Some centers also charge for meals and snacks separately.
Transportation is another consideration. If the nearest quality daycare center is far from home or work, daily commuting adds both time and fuel costs. See our data methodology for a full breakdown of cost factors. Use the affordability calculator to estimate total costs including these extras.
Quality Considerations
Cost is not the only factor. Nannies provide one-on-one attention, flexibility with schedules, and care in the child's own home. Children are less exposed to illnesses, which means fewer sick days for parents. Nanny care also accommodates irregular work schedules, early mornings, and late evenings.
Daycare centers offer structured curricula, socialization with peers, and regulatory oversight. Licensed centers must meet state-mandated staff-to-child ratios, undergo regular inspections, and employ trained staff. Child Care Aware of America provides resources for evaluating center quality through state QRIS ratings.
The Nanny Share Option
A nanny share offers a middle ground. Two families split the cost of one nanny, each paying 60-70% of the full-time rate. For a $700/week nanny, each family pays approximately $420-$490/week. The children get smaller group sizes than daycare but at a lower cost than a private nanny. This arrangement works especially well for families in the same neighborhood with children of similar ages.
County-by-County Variation
The daycare-vs-nanny cost gap varies significantly by county. In high-cost counties like those in California and Massachusetts, nanny wages are high but so is daycare tuition, narrowing the gap. In lower-cost counties in the South and Midwest, daycare is significantly cheaper and the gap widens.
Search for your county to see local daycare pricing data and use that as a baseline for comparing nanny costs in your area.
Frequently Asked Questions
For one child, a nanny is typically more expensive than center-based daycare. The national average for a full-time nanny is $600-$800 per week, while center-based infant care averages $250-$450 per week. However, for two or more children, a nanny can be more cost-effective since the per-child cost decreases.
Hidden nanny costs include payroll taxes (7.65% employer share of FICA), workers compensation insurance, paid time off, sick days, and potential overtime pay. These costs typically add 15-25% on top of the base salary. You are also legally required to provide a W-2 as a household employer.
For two children, daycare costs roughly double since each child pays full tuition (some centers offer 5-10% sibling discounts). A nanny caring for two children may charge 10-20% more than for one child, making nanny care potentially cheaper for families with multiple children.
Yes, many families use a hybrid approach: daycare during standard hours and a nanny or babysitter for early mornings, late evenings, or occasional coverage. Nanny sharing with another family is another option that splits costs while providing individualized care.
