This calculator sums the major categories using typical national averages that you can adjust to your situation.

FAQ

How much does a baby cost the first year?

With $80/month diapers, $150/month formula, $60/month medical, $40/month clothing, $2,000 in one-time gear, and $10,000 in annual childcare, the first year totals roughly $16,320.

What's the biggest cost driver in the first year?

Childcare, if used, dwarfs every other category — full-time daycare or a nanny commonly runs $8,000-$20,000+ a year depending on region, often exceeding all other baby expenses combined.

Does breastfeeding change the formula cost significantly?

Yes — exclusively breastfeeding can reduce or eliminate the formula line item, though it may add costs like a breast pump, nursing supplies, and potentially lactation consultant visits.

Should I include lost income from parental leave?

This calculator only covers direct baby expenses — unpaid leave or reduced income during parental leave should be budgeted as a separate, often larger, line item in your household's first-year financial planning.

Accuracy and limitations

Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
