Does a second child cost as much as the first?

Often less at first, because much of the gear, cot, pram, clothes, can be reused. But the ongoing costs that scale per child, such as childcare, food and activities, still rise, so the added cost grows as the second child does.

What are the main added costs of a second child?

Childcare is usually the biggest, followed by extra food, clothing, activities and a larger car or home if needed. Some one-off baby gear is reused, which softens the early cost compared with the first child.

Does Working for Families help with a second child?

Working for Families and other support can increase with a second child, easing the cost. This calculator shows the gross added cost; check your entitlements, as they may offset a meaningful part of it.

Baby Number Two Calculator

This New Zealand calculator estimates the added cost of a second child, where some gear is reused but childcare and food still rise. The second baby is often cheaper at first because the cot, pram and clothes carry over, yet the per-child running costs keep climbing. You enter the ongoing costs and the one-off gear you need to buy new, and the tool shows the extra weekly and yearly cost on top of your first child.

This is the gross added cost; Working for Families and other support can offset part of it, so check your entitlements. Childcare usually drops once the child starts school. Estimate only.

How it works

The calculator adds your extra weekly costs for childcare, food and nappies, and other items to give the ongoing extra per week, then scales it to a year. It adds the one-off gear you need to buy new to show a first-year total, which is usually the most expensive year. Because much of the big gear is reused from the first child, the second child often costs less to start than the first did.

Worked example

Extra costs of $220 childcare, $60 food and nappies and $30 other are $310 a week, about $16,120 a year. Add $1,500 of new gear and the first year is around $17,620. Once childcare reduces as the child grows, the ongoing cost falls considerably.
