How we build estimates
Methodology & sources
Each data table on this site is backed by a named source, last-reviewed date, and adjustment notes — and every CSV is downloadable below. Provenance is recorded at the category level (one source per table) for tables where all rows share a single underlying study, and at the row level for tables where rows come from different sources.
What we estimate, and how
Childcare
State-level annual cost ranges are derived from Child Care Aware of America methodology and state market rate surveys. We split each state into typical infant ranges for center-based care, family child care homes, and full-time nannies. Nanny share, part-time, and family help are derived from these baselines. We then prorate by the number of months you select and adjust for hours per week.
Birth & newborn medical
Out-of-pocket planning ranges are based on Peterson-KFF Health System Tracker data on the average employer-plan, marketplace, Medicaid, and uninsured experience for pregnancy, childbirth, and postpartum care, plus newborn medical spending in the first three months. We do not predict your specific bill — we provide a planning range and a list of questions to ask your insurer and hospital.
Diapers & wipes
Monthly diaper usage tapers from 10–12 changes per day at birth to about 5 by month 12, consistent with AAP guidance and parent surveys. Per-diaper costs are sampled across budget store brands, mainstream (Pampers/Huggies), and premium (Honest, Coterie, Hello Bello) at major U.S. retailers — last reviewed Q1 2026. Cloth diapering includes upfront stash cost and a monthly washing/electricity range.
Feeding
Standard powder formula assumes typical infant intake (around 25–30 oz/day in early months) at mainstream-tier retail prices. Sensitive, hypoallergenic, and ready-to-feed formulas use known retail premiums over standard. Breastfeeding supplies cover one pump (insurance covers most cases under the ACA), bottles, parts replacement, bras, pads, and an optional lactation consultant out-of-pocket.
Gear & nursery
Per-item costs are sampled from major U.S. retailers across budget, standard, and premium tiers. Registry coverage assumptions (low = 20%, medium = 45%, high = 75%) are based on industry reports from baby registry platforms. Used / hand-me-down OK applies a typical 45% reduction to non-safety items.
Misc recurring
Toiletries, baby OTC medication, laundry extras, photos, and baby classes — sampled and combined into a typical monthly range that we multiply by 12.

What this calculator is not
- It is not medical advice. We don't give feeding, formula, or pediatric guidance.
- It is not insurance advice. We can't tell you what your specific plan will pay.
- It is not a bill. It's a planning estimate using ranges, not a quote.
- It is not tax advice. We do provide a federal Child & Dependent Care Tax Credit + Dependent Care FSA planning estimator at /childcare-subsidy-calculator for 2026 rules, but that estimator does not model state tax credits, the Saver's Credit, ACTC interactions, or other deductions on your full return. Talk to a CPA for your actual filing.
- It is not a registry. We don't recommend specific products for affiliate revenue.
