Can I afford a kid on $500k income? (single)
Claire, 32, in Boston, MA
exampleSingle, first baby on the way · $500k/yr household income
They're expecting their first child in Boston and bracing for what it does to the budget.
A $500k salary feels like more than enough until you price out Boston daycare and realize you're looking at $2,400 a month before the kid can walk. Claire is expecting her first child, and the real question isn't whether she can afford it — it's exactly how much it costs and what it does to her financial trajectory.

The engine puts the total lifetime cost of this child at $641k inflation-adjusted: $2,400 a month in daycare through age 5, a $227k lifestyle bump across the years, and $414k in education costs over a lifetime. The surprising part is that Claire's savings rate only drops from 47% to 40% — meaning even after absorbing a $641k obligation, she's still putting away four dollars out of every ten she earns after tax.
The total lifetime cost is roughly $641k, about $227k 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 $48M to $45M, but your plan still works without shortfall.

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.
