Can I afford a kid on $100k income? (married)
A child costs more than most people's mortgage — and at 32, married, earning $100k, you're asking if your finances can absorb one. The math says yes, but the number behind that answer will stop you cold.

The inflation-adjusted lifetime tab comes to $444k, broken into $1,200 a month in daycare alone for the first five years, a $108k lifestyle bump across the childhood years, and $336k in net education costs — but your 36% savings rate is the reason the verdict lands on go, because it gives you the slack to absorb the near-term cash drain without torching your trajectory.
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 $7.2M 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 | $7,156,924 ($2.7M in today's dollars) | $23,856 | None | — |
| 2027 | Have a child next year | $5,696,110 ($2.1M in today's dollars) | $18,987 | None | -$1.5M |
| 2029 | Have a child in 3 years | $5,781,181 ($2.2M in today's dollars) | $19,271 | None | -$1.4M |
| 2031 | Have a child in 5 years | $5,860,215 ($2.2M in today's dollars) | $19,534 | None | -$1.3M |
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.
