The Real First-Year Cost of a Baby
Every list of baby costs is a shopping list. The two biggest costs are not things you buy. A typical first year comes to $25,800 - of which $10,800 is childcare and $6,000 is income given up on leave. The cot and the pram are the small part, and nobody warns you about the other two.
The two costs that are not on any list
Search for what a baby costs and you will find a list of things: cot, pram, car seat, clothes, monitor.
Add all of it up and it is genuinely the smallest part of the year.
A typical first year - three months off at half pay on a $4,000 monthly salary, childcare from month three at $1,200, from the cost of a baby calculator:
| Cost | First year | Share |
|---|---|---|
| Childcare | $10,800 | 42% |
| Income given up on leave | $6,000 | 23% |
| Ongoing costs (nappies, food, everything) | $6,000 | 23% |
| One-off buying | $3,000 | 12% |
| The first year | $25,800 | 100% |
$16,800 of the $25,800 is childcare and lost income. The shopping list is $3,000.
The one nobody warns you about
The income you give up while off work does not appear on any checklist, because it is not something you buy. It is something that stops arriving.
Three months at half pay on a $4,000 salary is $6,000 you simply do not receive.
Change the leave arrangement and it dominates everything:
| Leave | Income given up | First year total |
|---|---|---|
| 3 months, fully paid | $0 | $9,000 |
| 3 months, half paid | $6,000 | $25,800 |
| 6 months, unpaid | $24,000 | $40,200 |
The gap between the best and worst case is $31,200 - and almost none of it is about the baby. It is about the leave policy and the childcare start date.
Notice the first row: fully paid leave and staying home for the first year strips out both of the largest costs, leaving $9,000. Same baby. Same everything else.
The cost that does not stop
Childcare is $10,800 in the first year here - and unlike the buying, it carries on. In many places it rivals a mortgage payment for years.
Which makes it worth doing something most people leave too late: find out what childcare actually costs where you live, before deciding when to return to work.
The sums often change the plan. Returning at month three to a job paying less than childcare costs is a decision people sometimes make without ever putting the two numbers side by side.
What to actually do before the baby arrives
Build up the income you will lose. This is the single most useful thing, and it is unusually predictable - you know the figure months in advance and it lands all at once. Building $6,000 over the preceding year is a manageable target; finding it in the month it hits is not.
Find out your employer’s actual policy, in writing. “We have parental leave” covers everything from full pay to none at all, and the difference here was $31,200.
Price childcare in your area now. Not later. It shapes the return-to-work decision.
Do not over-buy. Much of the shopping list is optional or available second hand, and it is 12% of the year. Do not let it distract you from the two numbers above it.
The things that change at the same time
Two other decisions arrive with a baby and are easy to postpone:
Life insurance. Somebody now depends on your income. The life insurance calculator works out how much cover the job actually needs.
Your emergency fund. It was sized for your old life. A household with a child has less slack and more that can go wrong.
Neither is urgent in the first fortnight. Both are worth doing in the first year.
What to take away
- The two biggest costs are not things you buy. Childcare and lost income were 65% of this year.
- Find out your leave policy in writing. It swung this by $31,200.
- Price childcare before fixing your return date.
- Save the income you will lose, in advance.
- Ignore the shopping lists. They are the small part.
Work out your own first year in the cost of a baby calculator - it counts the leave and the childcare, not just the buying.
Common questions about cost of a baby
What is the biggest cost of a new baby?
Childcare, once you return to work, followed by the income you give up while off. On a typical first year those two come to $16,800 of a $25,800 total. The one-off buying everyone talks about is $3,000 - around 12%.
Why does nobody mention the lost income?
Because it is not a thing you buy, so it never appears on a checklist. Three months off with half pay on a $4,000 monthly salary is $6,000 of income you simply do not receive. With no paid leave at all and six months off, it becomes $24,000 - the largest single line by far.
How much difference does paid leave make?
Enormous. The same family with fully paid leave and no childcare in the first year spends $9,000 instead of $25,800. Paid leave and delaying childcare remove both of the largest costs at once.
What should I do before the baby arrives?
Build up whatever you would lose in unpaid leave. That single number is usually the largest and the most predictable - you know it months in advance and it lands all at once.
Does a second child cost the same?
Usually less. Most of the one-off buying carries over and you already know what you actually need. But childcare and lost income scale, and those are the two big ones, so do not assume it halves.
