Twins and Multiples Cost Calculator
Where the cost of multiples genuinely doubles, where it does not, and the childcare cliff that arrives with no gap between them.
Twins do not cost double: roughly 62% of baby equipment has to be bought twice and 38% is shared, but childcare and consumables are fully doubled and arrive in the same months — which is why the childcare bill, not the pram, is the cliff.

Frequently asked
Do twins cost twice as much as one baby?
Not for equipment, where around a third of the list is shared, and not for hand-me-down clothing where families often receive far more. But childcare, nappies, feeding and food all double exactly, and those are the large recurring lines — so the total sits much closer to double than parents expect.
What is the childcare cliff?
With children born apart, the highest childcare year for one is usually the cheapest for the other. With multiples, every child hits the most expensive band at the same time, so peak cost is two or three times a single child's peak rather than 1.5 times.
Is there financial help for multiple births?
It varies enormously by country. Multiple-birth associations in most countries maintain lists of retailer discounts, equipment schemes and any benefit differences, and they are usually far more current than a general parenting site can be.
