Daycare vs nanny cost

The structural difference

Daycare cost is per child. Nanny cost is per household. That single difference is the whole comparison, and it is why the crossover point sits somewhere around the second child in most markets.

Daycare's per-child cost is set by ratio, which varies by state: a preschool teacher at 1:10 is shared ten ways, an infant teacher at 1:4 four ways. A nanny is shared once, or twice if you have two children, and not at all otherwise.

Which is why the honest way to compare is annual household cost for the children you actually have, not a rate against a rate.

A nanny makes you an employer

This is the part that is routinely left out. A household that pays a nanny $3,000 or more in cash wages in 2026 owes the employer share of social security and Medicare tax, 7.65% of those wages. Pay $1,000 or more in any calendar quarter and federal unemployment tax applies too, plus any state unemployment insurance. Depending on the state you may also need workers' compensation, and household employment insurance that a homeowner policy may not include. Either way, part of the bill can come back through a dependent care FSA or the child care tax credit.

Then the terms: paid holiday, paid sick days, and cover for the days the nanny is unwell. A family with no backup pays twice on those days, or one parent stays home.

Add guaranteed hours. Most nanny agreements guarantee a weekly minimum whether or not the family needs all of it, which removes the flexibility people imagine they are buying.

Structure, not amounts. Household employment obligations vary by state — confirm yours with a payroll service or an accountant before you compare.

Where the crossover sits

Work it as annual household cost. For daycare: weekly tuition per child, times the weeks you are billed for, plus registration and supply fees per child. For a nanny: hourly rate times guaranteed hours times weeks, plus the employer share, plus paid leave, plus any agency fee.

With one child in most markets daycare wins clearly. With two, the nanny total stops scaling while the daycare total roughly doubles, and the comparison becomes real.

With an infant and a toddler it tilts further toward the nanny, because the infant place is the most expensive place in childcare — the ratio is commonly around 1:4 rather than 1:10, though states set their own, and the tuition reflects it.

What money does not capture

Daycare buys redundancy. Staff cover for each other, the program opens whether or not one person is unwell, and there is a licensing regime standing behind it. A nanny is one person, and one person can resign.

Daycare buys peers. For a two- or three-year-old, a room of other children is developmentally the point, and it is not something a nanny arrangement replaces easily.

A nanny buys hours and calm. No commute with a toddler, no 6pm deadline, care that flexes around shift work, and a sick child who does not have to leave the house. For some households that is worth a premium and for some it is the only workable arrangement.

The honest version: run both numbers, then choose on the non-money factors, because the numbers are usually closer than people expect and the fit is not.
