Child Cost Calculator

How much does a baby really cost? Enter your situation — see the real first-year cost, parental leave impact, and 3-year budget.

How to Use This Calculator

First Year Cost tab

The default tab. Select your childcare plan (daycare, nanny, or family), feeding method (breastfeeding, formula, or combo), and birth type (vaginal or C-section). Enter your insurance status — out-of-pocket birth costs change dramatically with or without insurance. The calculator totals birth costs, gear, diapers, feeding, pediatrician visits, and childcare — then subtracts the Child Tax Credit.

Parental Leave tab

Enter your annual salary, weeks of paid leave your employer offers, and your paid leave percentage (100%, 80%, 60%, etc.). The calculator shows your total income during the FMLA 12-week period and how much income you lose compared to working. Use this to plan your savings buffer.

3-Year Budget tab

See a year-by-year breakdown from birth through age 3. Costs change: childcare often increases, diapers decrease after potty training, and formula stops after year 1. This tab helps you budget for the full early childhood period.

The Formula

First-year cost is the sum of all major expense categories:

First Year = Birth Costs + Gear + (Diapers × 12) + (Feeding × 12) + (Pediatrician × 12) + (Childcare × 12) − Child Tax Credit

Birth costs vary by delivery type and insurance status. The calculator uses 2026 US averages:

Example

Maria & James — Phoenix, AZ

Maria earns $65,000/year. James earns $55,000. They're expecting their first child and want to understand the financial impact.

First Year Cost tab

First year total$23,380
Birth (vaginal, insured)$2,500
Childcare (daycare)$14,400
After tax credit$21,380

Childcare is 62% of the total cost. They compared with the "family" option (grandma offered to help 3 days/week) — total dropped to $12,980. That difference: $10,400/year.

Parental Leave tab

Maria gets 8 weeks paid at 60%. Income during 12 weeks of FMLA leave: $9,000 (vs. $15,000 if she worked). Income loss: $6,000. They started saving $500/month six months before the due date to cover the gap.

They shared the link with both sets of grandparents. The numbers made the "should grandma help with childcare?" conversation much easier — everyone could see exactly what was at stake.

FAQ

The first year typically costs $15,000–$30,000 depending on childcare choice, feeding method, and insurance. Childcare is the single largest expense, ranging from $0 (family) to $30,000/year (nanny). The calculator breaks down every category so you can see where the money goes.
Childcare, by far. Daycare averages $1,200/month ($14,400/year) and a nanny averages $2,500/month ($30,000/year). If a family member provides free care, total first-year costs drop dramatically. Run all three scenarios in the calculator to see the difference.
Federal law (FMLA) only guarantees 12 weeks of unpaid leave. Some states (California, New York, New Jersey, Washington, and others) offer paid family leave programs. Many employers offer paid leave voluntarily. Use the Parental Leave tab to calculate the income impact for your specific situation.
The federal Child Tax Credit is $2,000 per child per year for qualifying families (income limits apply). The calculator automatically subtracts this from your annual cost. Some states offer additional credits — check your state's tax authority.
The defaults are based on 2026 US national averages. Your actual costs will vary by location, lifestyle, and choices. The calculator is most useful for comparing scenarios (daycare vs nanny, breastfeeding vs formula) rather than predicting exact dollar amounts. Adjust the inputs to match your local costs.
