Cost of a Second Child
The marginal cost rather than double — with the hand-me-down effect, the childcare overlap and the thing that genuinely does double.
A second child typically costs meaningfully less than the first once hand-me-downs and shared household costs are counted, but the childcare overlap is set entirely by the age gap — and closing that gap by one year can add a full year of paying for two children at once.
Cost of a Second Child
Frequently asked
Does a second child cost double?
No. Housing, heating, activities and many household costs are shared, and clothing and equipment are largely handed down. The honest exception is childcare, which does not share at all.
What age gap is cheapest?
Financially, a gap wide enough that the first child has started school before the second needs paid care — which in most systems means three or four years. That is a cost calculation only, and it is one of many considerations that reasonably outweigh it.
What costs more than people expect?
The one-off transition costs: a bigger car, sometimes a bigger home, and lost income. They do not appear in per-year comparisons and they arrive all at once.
