Nanny Share vs Solo Nanny vs Daycare: $33,700 vs $58,900 vs $19,200 a Year Once You Add Taxes, Schedule, and DCFSA

Your childcare situation just changed. Maybe leave ended, a daycare waitlist fell through, or your last nanny gave notice. Now you're staring at three quotes: a daycare spot at $1,600 a month, a nanny who wants $23 an hour, and another family down the street who says, "Want to do a nanny share?"

The hourly rate and the monthly tuition are not the real numbers. The nanny's rate doesn't include your payroll taxes. The share rate doesn't say how many hours you're really covered. The daycare price doesn't say what happens when your child moves from the infant room to the toddler room.

Below I build a full-cost model for one child, then show which of your personal inputs flip the answer. Every dollar figure in the worked examples is an illustrative example I constructed, not a market average. Swap in your own quotes.

Why the headline price is the wrong number

Three things are happening at once in 2026:

• Daycare pricing depends heavily on where you live. The same infant slot can cost a fraction of the price in a low-cost state that it costs in a high-cost metro. See our state-by-state cost breakdown for the spread.
• Public help is a policy question, not a sure thing. The Economic Policy Institute has written about a proposed Trump administration child care plan that it says would redirect Child Care and Development Fund (CCDF) resources away from low-income working families. EPI's argument is that this could mean lost subsidies for some families, higher child care costs for everyone, and closures of some providers. EPI's preferred fix is to fully fund CCDF. Whatever your view, the practical takeaway is that if your budget assumes a subsidy, check your state's current rules before you build a plan around it. Our CCDF eligibility guide walks through how to check.
• Household budgets are stretched. NerdWallet's September 28 mortgage rate report says rates fell a little but are still solidly above 7%. If you bought or refinanced at a high rate, or are still renting because of it, that monthly payment competes directly with your childcare line. EPI's piece on wages, inequality, and America's affordability crisis makes the broader point that many households are squeezed on wages relative to costs. Childcare is one of the biggest line items in that squeeze.

Notice what these headlines have in common: none of them changes your personal math. What changes it is your metro, how many kids you have, their ages, your income, and your employer benefits. (The California wealth tax debate that Tax Foundation covers is a good example. It's a big story, but it doesn't move a typical family's childcare budget. Your DCFSA election does.)

The worked example: one infant, three arrangements

Assumptions for this example (all illustrative):

• One infant, full-time care, 45 hours a week
• Daycare: $1,600 a month
• Solo nanny: $23 an hour, paid for 52 weeks (including paid vacation and holidays)
• Nanny share: nanny earns $26 an hour, and two families split the wages evenly
• Federal marginal rate 22%, state income tax 5%
• Household employer costs per family: Social Security and Medicare employer share 7.65%, federal unemployment (FUTA) $42, state unemployment $300, payroll service and workers' comp $600

Solo nanny

Line item	Annual cost
Wages: $23 × 45 hrs × 52 weeks	$53,820
Employer FICA (7.65%)	$4,117
FUTA	$42
State unemployment	$300
Payroll service and workers' comp	$600
Total	$58,879

That's $58,879 for a nanny who "only" costs $23 an hour, about $5,000 more than the wage line alone. If the phrase "household employer" is new to you, it just means you're the boss on paper. If you pay a nanny more than the IRS threshold in a year, you owe payroll taxes on that pay, and yes, the IRS does go after families who skip it. See our breakdown of nanny tax compliance options for the DIY vs payroll service tradeoff.

Nanny share

Line item (per family)	Annual cost
Nanny wages: $26 × 45 hrs × 52 wks = $60,840, split two ways	$30,420
Employer FICA (7.65%)	$2,327
FUTA	$42
State unemployment	$300
Payroll service and workers' comp	$600
Total per family	$33,689

The share rate is higher per hour because the nanny is watching two children. Each family pays a lot less than the solo nanny but still much more than daycare. Notice that the fixed costs (FUTA, state unemployment, payroll service) don't shrink when you split. That's why a share saves less than half.

Daycare

12 months × $1,600 = $19,200. Some centers add a registration fee, supply fee, or closure-day charges. Ask for the full fee schedule and add it in.

What DCFSA does to all three

A Dependent Care FSA (DCFSA) lets you set aside pre-tax money from your paycheck for childcare. The 2026 limit is $7,500 per household. At a 22% federal bracket, 5% state tax, and 7.65% employee-side payroll tax, each pre-tax dollar saves you about 34.65 cents:

$7,500 × 0.3465 ≈ $2,599 in tax savings

You can use DCFSA for a properly paid nanny, a share, or a daycare, as long as you can document the care. (Employee-side FICA savings only apply if your employer's plan is set up normally, so confirm with HR.) Because the DCFSA uses up the expense base for the separate Dependent Care Credit on one child, the two don't stack fully here. Our DCFSA vs Dependent Care Credit comparison shows when to favor one over the other, especially at lower incomes.

Arrangement	Gross annual cost	After DCFSA savings (about $2,599)
Solo nanny	$58,879	$56,280
Nanny share (your half)	$33,689	$31,090
Daycare	$19,200	$16,601

For one infant in this example, daycare wins on price by a wide margin, and the nanny share beats the solo nanny by about $25,000 a year. This is the kind of side-by-side Kelivon runs for you, so you don't have to rebuild the spreadsheet every time a quote changes.

What flips the answer: your personal variables

The table above is one scenario. Here are the inputs that move it.

1. Number of kids

Daycare charges per child. A nanny charges per household (with a modest premium for a second child). Assume a second child adds about $2 an hour to the solo nanny rate.

Two kids in this example	Annual cost
Two daycare spots at $19,200	$38,400
Solo nanny at $25/hr, 45 hrs, 52 wks: $58,500 wages + $4,475 FICA + $42 + $300 + $600	$63,917

Daycare is still ahead by about $25,500, but the gap is much narrower per child. Break-even for a solo nanny against $19,200 daycare spots happens around three children (3 × $19,200 = $57,600, versus roughly $59,000–$64,000 for the nanny). If your daycare quote is higher, say in a high-cost metro, break-even arrives sooner. Our two kids, one nanny vs two daycare spots post goes deeper on that flip.

2. Your metro

If your daycare quote is $1,000 a month, the daycare vs nanny gap widens. If it's $2,800 a month ($33,600 a year), the nanny share at $33,689 is almost the same price as the daycare, and the share gives you one-on-one-ish care, flexible hours, and a caregiver who comes to you. Same math, different city, different winner. The nanny hourly rate also varies by metro, so get local quotes for both.

3. Your child's age

Daycare gets cheaper as kids age. Nanny wages generally don't fall, and a share gets harder to sustain when one child starts school. Here is an illustrative five-year path for one child:

Age	Daycare (example)	Solo nanny (example, flat)
0–1	$19,200	$58,879
1–2	$15,600	$58,879
2–3	$15,600	$58,879
3–4	$13,200	$58,879
4–5	$13,200	$58,879
5-year total	$76,800	$294,395

The nanny total ignores raises (which are normal) and assumes full-time hours the whole time, so it's a rough ceiling. The point is that infant year is the expensive year for daycare, and the price falls from there. If the pain is concentrated in the first 12 months, a short nanny or share stint followed by a switch to daycare can be a cost-smart plan. See why infant year costs the most.

4. Your income and benefits

Higher earners get more from DCFSA because their marginal rate is higher. Lower-income families may qualify for CCDF subsidies, but those come with income limits and, in some states, cliffs where a raise can cost you more in lost assistance than you gain. Given the policy debate EPI describes around CCDF funding, verify current eligibility and waitlist status in your state before you count on it. Also ask HR two questions: does the employer offer a DCFSA, and does it offer backup care or a childcare stipend? Either can change which option is cheapest.

Tell Kelivon your metro, kids, income, and benefits, and you can model this with your own numbers instead of my example ones.

Nanny share: the schedule is where the savings live or die

A share only saves money if the schedule works. Care.com's guide to creating a nanny share schedule covers the core tradeoffs: how the two families split hours, which home hosts on which days, and how to handle overlap so the nanny isn't underpaid or double-booked. Here is how those choices hit the budget:

• Full overlap (both kids together, same hours): the cheapest structure per family, because you're splitting one set of wages. This is the model in the example above.
• Alternating host homes: usually fine on cost, but agree in writing on who pays for food, supplies, and utilities at each house, because those costs are real.
• Staggered hours (one family needs 8–5, the other 9–6): the nanny's total paid hours go up, but your family's share doesn't fall proportionally. Model it before you agree to it.
• One family's hours drop or the child ages out: the nanny's income drops, so plan for that conversation and any notice or severance terms in advance.

Also decide who is the household employer. In many shares each family pays its own portion and files its own paperwork, so each of you carries fixed costs like state unemployment and payroll service. That's why the per-family cost in the table is $33,689 and not $29,440 (half of the solo total). More on this in our nanny share schedule cost analysis and our guide to nanny share vs nanny vs daycare.

Is it even worth going back to work?

This is the question behind a lot of these searches. If your take-home after taxes is, say, $4,800 a month and childcare is $1,600 (daycare) or $2,600 after DCFSA savings on a share, the math looks very different from a solo nanny at $4,700 a month, which would eat nearly all of it. That doesn't mean one choice is right. It means you should compare the full cost of each arrangement against your household's income, career trajectory, and what a pause would do to your retirement contributions and future pay. See our stay-at-home parent ROI analysis for that side of the ledger. With mortgage rates still above 7% per NerdWallet, a big fixed housing payment can make childcare the flexible line you're forced to squeeze. Model it honestly instead of guessing.

A checklist to build your own model

Before you commit to any arrangement, get these numbers:

1. Quoted price, plus every fee (registration, supplies, late pickup, closure days)
2. Hours you truly need, including commute and the days you work late
3. For a nanny or share: hourly rate, paid holidays and vacation, guaranteed hours, sick pay, and whether you cover a payroll service
4. Employer taxes: 7.65% FICA on the employer side, FUTA, and your state unemployment rate
5. DCFSA limit and your marginal tax rate (federal plus state plus employee-side payroll tax)
6. Subsidy eligibility and how long the waitlist is in your state
7. Backup care cost for when the nanny is out or the daycare closes
8. Age progression: what does this arrangement cost in years 2, 3, and 4?

If you skip any of these, you're comparing a sticker price to a fully loaded price, and the sticker price will win every time.

The bottom line

In this example, a solo nanny costs $56,280 after DCFSA savings, a nanny share costs $31,090, and daycare costs $16,601, all for one infant. Change any one input (a second child, a $2,800-a-month daycare quote, a state with higher unemployment tax, a schedule that doesn't overlap) and the ranking can flip. There's no judgment attached to any of the three options. What matters is that you see the total before you sign anything.
