How We Calculate Childcare Costs

Last updated: October 24, 2026 · Next scheduled review: January 2027

Childcare cost data is fragmented across federal agencies, state departments, industry surveys, and private platforms. There is no single authoritative number for what daycare costs in a given zip code. Our calculator stitches together the best public sources and applies a transparent set of rules to produce a cost range a family can use as a starting benchmark. This page documents the full methodology so families, journalists, and researchers can evaluate the rigor of our estimates and reproduce our reasoning.

1. Data Sources

Our cost figures were rebuilt on October 22, 2026 from Care.com data. Government data supplies local price levels where Care.com publishes only national numbers:

• Care.com — 2026 Cost of Care Report (published February 3, 2026). National average weekly rates for one child: daycare center $332 for an infant and $308 for a toddler; nanny $870. We annualize weekly rates over 52 weeks ($332 × 52 = $17,264, shown as $17,260). This is the source of our national daycare figures; in-home daycare is derived from them (see below). Care.com's "family care center" rate is not used: it jumped from $230 a week in its 2024 report to $344 in 2025 while its daycare rate moved only $321 to $343, which points to a change in what the category covers rather than in prices.
• Care.com — Cost of Care Calculator (rates as of October 2026). Average starting hourly rates for nannies and after-school nannies in each metro's principal city (two cities averaged for Dallas/Fort Worth, Raleigh-Durham, and Tampa/Orlando); U.S. averages are $22.26/hour and $19.70/hour. This is the source of every nanny and nanny-share figure: full-time nanny = local rate × 40 hours × 52 weeks.
• Care.com — nanny share guidance (September 2026). Each family in a two-family nanny share typically pays about two-thirds of a private nanny's rate.
• U.S. Department of Labor, Women's Bureau — National Database of Childcare Prices (NDCP), and the Economic Policy Institute (EPI). Care.com does not publish daycare prices by metro, so each metro's daycare figures keep that metro's price level relative to the national average from our prior NDCP/EPI-based dataset, re-anchored to Care.com's national rates. In-home (family) daycare keeps that dataset's in-home-to-center ratio for each metro and age — about 79% of the center price for infants nationally, consistent with home-based care pricing below centers in NDCP data. School-age before/after-care figures also come from that dataset, because Care.com publishes no school-age center rate.
• State child care market rate surveys and NDCP county medians (local calibration, October 23, 2026). We checked every metro's infant daycare center and in-home daycare figures against the latest state market rate survey for its core county, or the DOL NDCP county median where no survey was available, normalized to 2026 dollars at about 4% a year. Where our figure differed by more than 15% from the median of those local benchmarks, we re-anchored it to the benchmark and scaled toddler and preschool rates by the same factor. 27 figures in 20 metros were re-anchored; school-age and nanny figures were not changed. On October 24, 2026 we applied the same rule to six smaller metros the calculator prices without a city page (Birmingham, Des Moines, New Orleans, Anchorage, Northern New Jersey and Boise), normalizing each survey to September 2026 with the BLS consumer price index for day care and preschool. The benchmark was the latest state survey's median for the metro's county or region; where a state publishes no local median (Iowa, New Jersey), we used the median of the survey's statewide median, the DOL county medians and Child Care Aware of America's statewide average. Six figures were re-anchored: in-home daycare in Anchorage (−13%), Boise (−18%) and Northern New Jersey (−16%), center care in New Orleans (−16%), and both center (−16%) and in-home daycare (−29%) in Des Moines. Birmingham's figures were within 15% of Alabama's 2024 survey.
• Child Care Aware of America (CCAoA) — Child Care in America: 2025 Price & Supply (published May 2026; state data as of December 2025). Statewide average prices for full-time infant, toddler and 4-year-old care in licensed centers and family child care homes. Since October 24, 2026 these averages, raised 3.2% to 2026 prices with the BLS day care and preschool price index (series CUUR0000SEEB03), price zip codes outside our metros in 19 states, and they are the headline figures on our statewide-average state pages. Used for informational purposes with credit to Child Care Aware of America.
• U.S. State Department — J-1 Au Pair Program. Source for the federally set au pair weekly stipend ($195.75/week as of 2026), maximum hours (45/week, 10/day), and program structure. Au pair total annual cost incorporates the stipend, agency fees ($9,500–$12,000 typical), room and board (imputed), and education stipend ($500).
• State childcare licensing and assistance agencies — Source of state CCDF (Child Care and Development Fund) eligibility rules, income limits, copay formulas, and supplemental state-only programs (e.g., New York's Child Care Subsidy, California's Alternative Payment Program).

2. Regional Mapping: From Zip Code to Cost Range

We map U.S. zip codes to 44 metropolitan regions using the first three digits of the zip code (the ZIP3 prefix). ZIP3 corresponds roughly to a USPS sectional center, which in turn corresponds well to metro labor markets and the boundaries used in DOL county-level pricing tables.

For each ZIP3-mapped region we maintain one average annual cost per care type and age group. ZIP3 prefixes outside our metros use a statewide average in the 19 states where we have no state page and Child Care Aware of America publishes one (Alabama, Alaska, Arkansas, Delaware, Idaho, Iowa, Kansas, Louisiana, Maine, Mississippi, Montana, Nebraska, New Hampshire, New Jersey, North Dakota, South Dakota, Vermont, West Virginia and Wyoming), and a regional average (Northeast, South, Midwest, Mountain West, or West) elsewhere. A user entering zip code 10001 (Manhattan) is matched to the New York City metro record. A user entering 12345 (Schenectady) is matched to the Northeast regional average, and 36104 (Montgomery) to the Alabama statewide average.

Statewide averages: center and in-home daycare figures are CCAoA's center and family child care averages by age, raised 3.2% to 2026 prices (Louisiana reports no family child care average, so its in-home figures keep the South region's in-home-to-center ratio). CCAoA has no school-age price, so school-age figures scale the regional figure by the state's infant price relative to the region's. Nanny figures use Care.com's state-average rates with the same formula as our metros. Where CCAoA's average for an older age is higher than for a younger one, we use the younger age's price.

Limitations: ZIP3 mapping cannot capture intra-metro variation. A daycare on the Upper West Side will price differently from one in the Bronx, even though both share the NYC region in our model. Treat the calculator's figures as a regional average and compare them with quotes from local providers.

3. Age-Group Cost Differentials

Childcare prices fall as children age, driven primarily by mandated staff-to-child ratios. How each age group is priced:

• Infant (0–12 months) and toddler (1–3 years): Care.com's 2026 national weekly rates. Toddler care runs about 7% below infant care at centers ($308 vs. $332); in-home daycare follows the center figures at the prior in-home-to-center ratio.
• Preschool (3–5 years): Care.com does not publish a preschool rate, so we apply our prior dataset's preschool-to-toddler ratio (0.88) to Care.com's toddler rate.
• School-age (5–12 years, before/after care): center and family-care figures are carried over from our prior NDCP/EPI-based dataset. The calculator adds 35% for full-day summer care.
• Nannies: Care.com's local nanny rate does not vary by age, so infants, toddlers, and preschoolers share one full-time figure. School-age children are priced as after-school care: Care.com's local after-school nanny rate for 15 hours a week (Care.com's convention for after-school sitters) over 52 weeks, plus the summer surcharge.

All annual figures are rounded to the nearest $10.

4. Sibling Discounts

When the calculator detects two or more children in the same household, we apply sibling discounts that reflect typical industry practice:

• Daycare centers and in-home daycares: 5–10% off the second child, 10–15% off the third child
• Nanny: priced per household. The child with the highest cost carries the full rate and each additional child adds about 5%, based on Care.com's 2026 rates ($952 a week for two children vs. $870–$936 for one).
• Nanny share: each family pays about two-thirds of the local nanny rate (Care.com); additional children in the same family add about 5%.
• Au pair: no incremental cost for additional children — the program is flat-rate per household

Part-time schedules. The cost surveys we use publish full-time prices, so part-time costs are modeled: the calculator and our part-time daycare page price 4, 3 and 2 days a week at 85%, 65% and 45% of the full-time rate for every care type except au pairs, reflecting the per-day premium providers charge to hold a part-time spot. Au pair costs are not prorated.

5. Tax Calculations

5.1 Dependent Care FSA

For tax year 2026 we assume a maximum annual contribution of $7,500 per household ($3,750 if married filing separately), per IRC §129 as amended by P.L. 119-21 (previously $5,000 / $2,500). FSA tax savings are computed as the contribution amount multiplied by the family's marginal federal income tax rate (estimated from AGI less the standard deduction, on the 2026 IRS brackets for married filing jointly, head of household or single in Rev. Proc. 2025-32), capped at the estimated income tax owed, plus 7.65% FICA savings (Social Security 6.2% + Medicare 1.45%) on the FSA-contributed amount. Social Security tax applies only to wages up to the 2026 wage base of $184,500 (IRS Topic 751), so for single, head-of-household and married-filing-separately filers we treat the income entered as wages and count only the 1.45% Medicare saving on FSA dollars above that base. For married couples filing jointly we assume the FSA is through a spouse earning under the base.

5.2 Child & Dependent Care Credit

Computed per IRS Form 2441. Qualifying expenses are capped at $3,000 for one child or $6,000 for two or more. For 2026 the credit percentage ranges from 50% down to 20% based on AGI (P.L. 119-21; Form 2441 2026 phaseout schedule), with different AGI thresholds for joint filers (20% above $206,000) and other filers (20% above $103,000). Dependent Care FSA dollars reduce the expenses eligible for the credit, so a full $7,500 FSA eliminates the credit for one or two children. The credit is nonrefundable, so it is capped at the estimated federal income tax left after the FSA's saving, and families who owe little or no federal income tax may see a $0 credit. It is applied before the Child Tax Credit (the Form 2441 Credit Limit Worksheet subtracts only the foreign tax credit), so the Child Tax Credit doesn't reduce it. State credits figured as a share of the federal credit use the amount before this cap. The calculator tests each FSA contribution amount and shows the combination with the largest total savings, state credits included.

5.3 State Tax Benefits

We track state-level credits and deductions in 14 states with notable benefits, including New York (110% of federal credit), California (refundable state credit at low incomes), Minnesota (refundable up to $720), and others. The calculator applies the appropriate state benefit based on the zip code's mapped state.

6. State Subsidy Eligibility

State subsidy programs (CCDF and state-only supplements) are flagged based on the user's zip-derived state and household AGI. Eligibility limits are stored as a percentage of State Median Income (SMI) per the state's published rules. A flag is triggered when AGI falls below the state's stated eligibility limit at the chosen family size.

Important: Eligibility flags are advisory only. Actual eligibility is determined by the administering agency and may depend on factors not captured by our model — work requirement, asset test, citizenship/residency, priority categories. Always confirm with your state's lead agency before relying on subsidy assumptions.

7. Multi-Year Cost Projection

When a user has more than one child or selects a multi-year view, the calculator projects costs forward using a 4% annual inflation assumption, transitioning each child to lower-cost age brackets as they grow. Inflation rate is reviewed annually against the BLS Consumer Price Index for All Urban Consumers, Day care and preschool subindex.

8. Affordability Benchmark

Our calculator uses 7% of household income as its affordability benchmark. HHS set 7% as its benchmark for affordable child care copayments in the 2016 Child Care and Development Fund (CCDF) rule, and the March 2024 CCDF rule made it a binding cap on subsidy copayments. That cap was rescinded effective July 13, 2026 (91 FR 25796), but 7% remains the most widely cited affordability yardstick. The calculator reports the percentage of AGI each care option would consume and flags any that exceed 7%.

9. Update Cadence

• Annually (each calendar year): Federal tax limits (FSA, Credit percentages), FICA rates, state median income figures, CCDF eligibility thresholds, au pair stipend rate.
• Annually (each winter): Care.com Cost of Care Report national daycare and family-care rates, and Care.com local nanny rates for every metro.
• Biennially or when new vintage is published: DOL NDCP metro price levels.
• Ad hoc: Corrections submitted via [email protected] are reviewed within 5 business days; substantive corrections are reflected on the affected page within 10 business days.

10. Known Limitations

• Intra-metro variation (neighborhood-level differences) is not captured beyond the low–high range.
• Specialty care (Montessori, Reggio, language-immersion, special needs) often prices above our center averages, though some programs charge at or below local center rates; see our Montessori cost guide for published tuition examples.
• Nanny costs assume gross-to-employer cost including employer-side payroll taxes; net pay to the nanny is lower.
• Tax calculations are estimates and do not account for the Alternative Minimum Tax, phaseouts beyond the Child & Dependent Care Credit, or interactions with other credits.
• Subsidy availability flags reflect program existence and basic income thresholds only — not waitlist status or funding availability in a given year.

11. Versioning & Change Log

• October 2026 rebuild: Rebuilt all cost figures from Care.com — national daycare and family-care rates from the 2026 Cost of Care Report, nanny and nanny-share figures from Care.com's October 2026 local rates for each metro, and metro daycare levels re-anchored to Care.com's national rates. Nanny costs in the calculator are now priced per household (additional children add about 5%) instead of a full salary per child. Unified the calculator and city-page data (13 metros had drifted apart) and gave San Jose, Louisville, and Oklahoma City zip codes their own metro figures.
• 2026 update (April 2026): Refreshed metro cost bands from DOL NDCP 2024 release. Federal tax figures are for tax year 2026. Added 4 new state subsidy program records.
• 2025 update (March 2025): Added nanny share modeling for 5 additional metros. Refined age-group multipliers based on DOL NDCP 2022 data.
