At What Age Is It Most Expensive to Raise a Child?

Newborn, toddler, school-age, or teen โ€” where the money goes.

At what age is raising a child most expensive?

Costs concentrate at two peaks: the early years (prenatal through age 5, driven by newborn needs and childcare/enrichment) and the teen years (ages 12โ€“18, driven by education and activities). The middle school-age years are relatively steadier.

Two peaks: ages 0โ€“5 and 12โ€“18.

What drives early-years cost?

Prenatal care, baby gear, and childcare/enrichment ("activities") dominate the first five years.

What drives teen-year cost?

Education and activities rise sharply from age 12; this is also when optional tutoring and extracurriculars add up.

Does cost ever go down?

Per-child cost falls as family size grows โ€” hand-me-downs, shared bedrooms, and sibling discounts mean a second or third child is cheaper per head than the first.
