Childcare is the third-largest household expense. Most parents pick on instinct. Here's the math.
Center daycare, in-home daycare, nanny, nanny share, au pair, grandparent, stay-home parent. Each has very different cost structures — and very different hidden taxes (FSA, Dependent Care Tax Credit, household-employer payroll for a nanny, lost income + retirement contributions for a stay-home parent). This tool builds the real net cost per option and tells you the cheapest one for your family.

STAGE 1 OF 5
Family situation
Cost varies enormously by number of kids, ages, work arrangement, and household income. Get the situation right first.
Daycare cost scales linearly with kid count. Nanny scales weakly (one nanny can handle 2-3 kids of compatible ages, doesn\'t scale to 4+).
Infant daycare (0-12 mo) is 30-50% more expensive than toddler (1-2) or preschool (3-5). Some centers don\'t accept under-6-mo babies at all.

Full-time daycare typically 45-55 hrs/wk to cover working parents. Nanny 40-50 hrs. Part-time options exist at proportional cost.
For tax-credit calculations. 2024 MFJ: 22% to $201K, 24% to $384K, 32% to $487K.

What this tool measures. The headline childcare price tag is not the right number to compare options. The right number is NET cost after Dependent Care FSA (up to $5K MFJ), Child & Dependent Care Tax Credit (20-35% of expenses, capped), household-employer compliance costs (a nanny is a W-2 employee = payroll, workers comp, employer FICA, often $50-150/mo in compliance services), and — for the stay-home option — lost income + retirement contributions + career re-entry friction. We build all of it.
STAGE 2 OF 5
Childcare options — the real cost structure of each
Adjust defaults to your local market. Cost varies 2-3x by metro area (NYC/SF top, Midwest/South bottom).
Center-based daycare
National median ~$1,800. NYC/SF/DC/Boston: $2,500-3,500. Midwest/South: $1,200-1,800.
$
~70-85% of infant cost. National median ~$1,400. NYC: $2,000-2,800.
$
In-home daycare (family daycare)
Licensed in-home daycare run by a state-certified caregiver in their own home. Typically 25-40% cheaper than center. National avg $900-1,400.
$
Required for FSA and tax credit. Most licensed in-home daycares can provide a federal tax ID. Unlicensed cannot.
Nanny (household employee)
National avg $20-25/hr. NYC/SF: $25-35/hr. Live-in lower. Live-out higher. Experienced or specialized: $30+.
$
You must pay for guaranteed hours even if not used. Typically 45 (5 days × 9 hr). Don\'t pay overtime under 40, pay 1.5x over 40.
Standard: 2 wks vacation + 5 sick + 6 federal holidays = ~20 paid non-work days. You pay full rate.
$
Nanny share (split with another family)
Two families split one nanny, both kids together. Nanny gets a premium (often 1.3-1.5x solo rate), so each family pays ~60-70% of solo cost. Total nanny take-home goes UP, each family\'s cost goes DOWN.
$
Households still split payroll/workers comp. Lower per-family but identical structure.
Au pair (live-in international)
Au pair program: cultural-exchange J-1 visa, max 45 hr/wk, weekly stipend ~$200 + agency fee ~$10K/yr + room/board (you provide private bedroom + meals).
$
CCAP, Cultural Care, AuPairCare, etc. Includes screening, matching, visa support. $9-12K/yr typical.
$
Bedroom you\'re not renting + meals + car use. Conservative $400-600/mo equivalent value, but it\'s not cash out the door.
$
$500 minimum per year toward community college / continuing ed. Some programs require $1,000.
$
Grandparent assistance
Most realistic: grandparent fills part of week (1-3 days), other days use paid care. Set 100% if grandparent is full coverage.
%
Should not be wage-coded. Gift-equivalent below annual exclusion ($18K/2024 per parent per grandparent) is non-taxable. Hosting dinners, paying car expenses, vacations together — all non-wage. Default modest.
$
STAGE 3 OF 5
Tax angles — FSA, Dependent Care Credit, household employer compliance
Three tax mechanisms reduce childcare costs. The FSA is the strongest for high-AGI families; the credit is stronger for low-AGI; household-employer compliance is a real cost for nannies.
Cap: $5,000 MFJ / $2,500 each if filing separately. Reduces taxable income by election amount. Best for high-AGI families. Must be employer-sponsored — not all employers offer.
$
Both must have earned income for the DC FSA and DCTC. Single parent: only need one. If one parent is full-time student or disabled, they can be deemed to have earned income.
Federal credit: 20-35% of qualified expenses, depending on AGI. AGI under $15K = 35%. AGI over $43K = 20%. Capped at $3K (1 kid) or $6K (2+ kids) of expenses. Most middle/upper-middle families get 20%.
%
~25 states offer state credits ranging 20-100% of federal. NY, IL, CA notable. Conservative default 0%; raise if your state has one.
%
Household-employer compliance (nanny only)
You owe employer half of Social Security + Medicare on a nanny\'s wages. Cannot be avoided. The nanny pays the other 7.65%.
%
FUTA: 0.6% of first $7K wages = ~$42. State unemployment (SUTA): varies by state, $200-1500/yr. Workers comp: required in most states, $300-1200/yr for a household employee.
$
HomePay, GTM, Poppins, SurePayroll. Handles W-2, tax filings, direct deposit. $50-100/mo = $600-1200/yr. DIY possible but most families pay for service.
$
Schedule H filing + W-2 prep. Many payroll services include; some require CPA. Default modest.
$
"Under the table" is not an option. Paying a nanny cash without W-2 is illegal (IRS, state labor, workers comp). The risks: (1) audit triggers from nanny filing for unemployment when laid off — happens regularly, (2) workers comp claim if injured in your home, no coverage, (3) immigration/Schedule H red flags for high-income filers, (4) nanny tax problem at Senate-confirmation level for any future appointed role. Use a payroll service. The compliance cost is the price of admission.
STAGE 4 OF 5
Hidden costs and the stay-home decision
Backup care, sick days, parent commute time, and — for the stay-home option — the full cost of one parent leaving the workforce.
Daycare excludes sick kids — typical ~8-15 days/yr. You miss work, take PTO, hire backup, or family fills in. Conservative annual hit $1-3K.
$
Center-based daycare adds drop-off/pickup time you wouldn\'t otherwise spend. ~3-5 hr/wk for two-kid families.
Reasonable estimate of your time. Used to value drop-off time and stay-home decision.
$
Stay-home parent analysis
Used to calculate lost income. We use the income of the parent you select.
Employer 401(k) match + your contribution you\'d miss. Typical: 6% employer match + 10% personal × salary. Default conservative.
$
Health insurance premium subsidy, dental, vision, life, disability, etc. If other parent can cover family on their plan, this drops to 0.
$
If stay-home, how many years total before re-entering. Used for career-trajectory cost estimation.
Research shows: women who leave workforce for 3+ years return at ~80-90% of prior salary, with slower growth. Conservative default 15% penalty on lifetime earnings post re-entry.
%
Used to size the career-penalty cost. If re-entering at 35 with 30 years to age 65, the 15% penalty applies for 30 years.
