Can I afford a kid on $300k income? (married)
At $300k combined income, 'can we afford a kid?' feels like it should have an obvious answer — but the real question is whether your plan survives $619k in lifetime costs without derailing everything else you've built.

Total lifetime cost (lifestyle + education, inflation-adjusted)
Daycare (0–5)
$2,400/mo
Lifestyle bump
$205k
Net education
$414k
Savings Rate
49%
The math actually works in your favor: a 49% savings rate means you absorb the $2,400/mo daycare hit in the early years without touching your $96k in liquid savings, and the $414k net education cost has decades of compounding runway ahead of it — the $205k lifestyle bump is the quieter threat most couples underestimate.
The total lifetime cost is roughly $619k — about $205k in extra day-to-day lifestyle spending and $414k in out-of-pocket education (daycare through college), all inflation-adjusted. Having a child next year reduces your retirement NW from $28M to $26M, but your plan still works without shortfall.
| Scenario | Timing | Retire NW | Retire SWR/mo | Shortfall | NW Impact |
|---|---|---|---|---|---|
| No kid | No new child | $28,493,067 ($11M in today's dollars) | $94,977 | None | — |
| 2027 | Have a child next year | $26,026,410 ($9.8M in today's dollars) | $86,755 | None | -$2.5M |
| 2029 | Have a child in 3 years | $26,185,960 ($9.9M in today's dollars) | $87,287 | None | -$2.3M |
| 2031 | Have a child in 5 years | $26,334,415 ($9.9M in today's dollars) | $87,781 | None | -$2.2M |
This analysis includes $414k 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.
Your numbers say go, but model the exact timing of that $2,400/mo daycare against your actual monthly cash flow — that's where most $300k households feel the pinch they didn't see coming.
