Can I afford a kid on $100k income? (married)
Sofia & Omar, 32 and 31, in Minneapolis, MN
exampleMarried, first baby on the way · $100k/yr household income
They're expecting their first child in Minneapolis and bracing for what it does to the budget.
A first child costs Sofia & Omar $444,000 over a lifetime, inflation-adjusted. That number sounds terrifying, but the math says they can do it without blowing up their financial plan.

Savings w/ kid
36% → 19%
The immediate pressure isn't the $336k in education costs down the road. It's the $1,200 a month in daycare starting at birth, which alone drops their savings rate from 36% to 19%. That's the constraint to plan around now, not the tuition bill that arrives in 17 years.
The total lifetime cost is roughly $444k, about $108k in extra day-to-day lifestyle spending and $336k in out-of-pocket education (daycare through college), all inflation-adjusted. Having a child next year reduces your retirement NW from $7.4M to $5.7M, but your plan still works without shortfall.
| Scenario | Timing | Retire NW | Retire SWR/mo | Shortfall | NW Impact |
|---|---|---|---|---|---|
| No kid | No new child | $7,439,066 ($2.8M in today's dollars) | $24,797 | None | — |
| 2027 | Have a child next year | $5,677,555 ($2.1M in today's dollars) | $18,925 | None | -$1.8M |
| 2029 | Have a child in 3 years | $5,804,082 ($2.2M in today's dollars) | $19,347 | None | -$1.6M |
| 2031 | Have a child in 5 years | $5,921,929 ($2.2M in today's dollars) | $19,740 | None | -$1.5M |
This analysis includes $336k in engine-modeled out-of-pocket education (daycare through college, inflation-adjusted, net of any 529 draws). Many families use student loans, scholarships, 529 plans, or community college to reduce this. Without college funding, the financial impact is significantly lower. The decision to start a family involves deeply personal considerations that no spreadsheet can capture.
Run your own numbers to see exactly which year daycare tightens the budget most, and whether front-loading retirement contributions before the baby arrives changes your outcome.
