Cost of Having a Baby Calculator
Your situation
Two choices to start — every cost line is pre-filled from national data or a labeled assumption, and all of it is editable.
About 1 in 3 US births is a C-section — worth seeing both numbers
The biggest controllable line after childcare
How we calculate this
We split the first year into one-time costs (birth and the gear you buy once) and recurring costs (childcare, feeding, diapers, clothing, the added insurance premium) — because the scary headline number and your ongoing monthly reality are different problems.
About the birth number: the $15,200 (vaginal) and $19,300 (C-section) defaults are FAIR Health's average in-network allowed cost — what insurers negotiate with providers. It is not a "hospital bill," and if you're insured it's not what you'll pay: your deductible and out-of-pocket max usually cap your share far lower. We default to the allowed cost because it's the honest, sourced national figure; enter your plan's OOP max if you know it.
Childcare dominates everything else. Full-time infant care averages $17,264/yr nationally (Care.com 2026), and we default to 9 months of it in year one — parental leave usually covers the start. The gear, diaper, feeding, and clothing lines are labeled model assumptions; they vary too much by family for a sourced national figure, so edit them freely.
Not included: lost wages during unpaid leave (that's the parental leave calculator's job), college savings, and life insurance — the two things a new dependent should make you price next.
Real scenarios
The typical setup: about $35,800 in year one
A vaginal delivery, formula feeding, and 9 months of average-priced daycare lands at $35,848 — $17,200 of it one-time (birth at the allowed cost plus gear) and $18,648 recurring. And childcare alone is $12,948 of that: nearly 70% of the recurring total.
A C-section moves the total to $39,948
The delivery difference is about $4,100 at in-network allowed rates — real money, but note it's a one-time line. Roughly one in three US births is a C-section, so budget for the possibility rather than the hope.
A stay-home year changes the math completely
Breastfeeding and no paid childcare drops year one to $21,600 — but that figure excludes the forgone salary, which usually dwarfs the savings. That trade-off is exactly what the parental leave calculator is being built to price.
