Is going back to work worth it once you've paid for childcare?

You've probably run the sum in your head at some point (usually late at night). Your pay, minus the childcare fees, minus tax, and you find yourself wondering how much of the second wage you'll get to keep. It's one of the most common questions parents ask before heading back to work.

That question deserves a proper answer, and the good news is the maths is friendlier than the version most people run in their head. That version compares a whole salary against the total childcare bill, which isn't the right comparison. A more useful one looks at a single day at a time: what does each extra day of work add to your pocket once tax and the gap fee come out? Here's how to work it out.

Does childcare cancel out a second income?

Going back to work almost always leaves your family better off, even after childcare, and the Child Care Subsidy is a big part of why. How much you keep depends on the days you book and what you both earn, and the clearest way to see it is day by day: what a day of work adds to your take-home pay, next to what that day of care costs after your subsidy comes off.

In a two-income household, one income tends to cover the shared costs that were always there, and the returning parent's income is the one families weigh against childcare. That returning income is taxed at your marginal rate, so the top slice of it is taxed a little more heavily than your first earnings, and each day of work comes with a day of care. Seeing the per-day picture is what turns a vague worry into a clear number you can plan around.

The headline fee is rarely what you end up paying. The Child Care Subsidy is designed to bring the cost of care down, and for most families it covers a big share of the bill. If you like the wider context, we've mapped out how much childcare costs around the world.

How the 3 Day Guarantee changes childcare costs when you go back to work

Since 5 January 2026, the 3 Day Guarantee means every family eligible for Child Care Subsidy can get at least 72 hours of subsidised care a fortnight, which works out to three days a week, no matter how much you work. This replaced the old activity test that used to tie your subsidised hours to your work and study hours.

For your maths, that's a meaningful shift. A part-time return of two or three days is now subsidised in a way it often wasn't before, when low activity could mean few subsidised hours or none. To reach up to 100 hours a fortnight, the four-to-five-day range, you and your partner each still need more than 48 hours of recognised participation (work, study and similar) per fortnight. So the first three days are the easy part, and the fourth and fifth days are where activity still counts.

What a day of work is really worth after childcare

To see what a day of work adds, put two numbers side by side: what that day adds to your take-home pay, and what that day of care costs you. Take your daily earnings after tax, subtract the daily gap fee (the centre's fee minus your Child Care Subsidy), and what's left is what the day puts in your pocket.

A few things move that answer:

Your daily take-home. Your returning income is taxed at your marginal rate, the rate that applies to the top slice of your income, so those top dollars are taxed more heavily than your first ones. This is general information rather than tax advice, and a registered tax agent can model your exact position.
The daily gap fee. This is the centre's fee minus your subsidy. The subsidy applies up to an hourly rate cap, and if your centre charges above the cap, you pay the full difference on those hours.
Your Child Care Subsidy percentage. Your subsidy rate is based on your combined family income. For the 2026-27 year, families earning up to around $88,500 get the maximum 90 per cent, and the rate tapers down by 1 per cent for every $5,000 above that, reaching zero once family income passes about $538,520. When you go back to work, your combined income rises, which can nudge your percentage down a little, so it's worth modelling rather than assuming.
The number of days. Every eligible family gets 72 subsidised hours a fortnight, which covers about three days. Reaching the 100-hour level that stretches to four or five days needs the higher participation from both of you.

How many days a week is it worth going back to work?

There's no single number of days that's right for everyone, and the subsidy supports you whether you work three days or five. Every eligible family gets three subsidised days, and four or five days draw on up to 100 subsidised hours once you and your partner each do more than 48 hours of recognised participation a fortnight. Your per-day numbers aren't identical across the week, so understanding them helps you plan the schedule that suits your family. The first three days are subsidised for every eligible family, so they tend to give you the clearest return. Beyond that, the subsidy scales up with your work.

Knowing your after-tax pay and your gap fee for each day means you can choose your working pattern with your eyes open, whether that's three days, four or five. There's no single right number, only the one that fits your family, and the subsidy is built to support more of your care as you take on more work.

Why going back to work is worth it beyond the childcare costs

The day-by-day sum captures this financial year, but the value of going back to work stretches well beyond it. Staying connected to work protects things that don't show up in a single year's figures and add up over time.

Super. Your employer's contributions keep landing in your super while you're working, and that's money that compounds for decades.
Earning power. Time out of the workforce can slow pay progression. Staying in, even part-time, keeps your skills current and your options open.
Household resilience. Two active incomes give a family more of a buffer if one is ever lost.

Even in a tighter year, staying in the workforce keeps your career moving and your options open, and that pays off long after the early childcare years. The numbers are one useful input, and for most families the fuller picture makes going back to work well worth it.

How to calculate whether going back to work is worth it

You can work out whether going back to work is worth it in five quick steps, using your after-tax daily pay and your childcare gap fee. You don't need a finance degree for it. Here's a simple way to run the numbers on your own situation:

Work out your after-tax pay for a single day of work.
Find your centre's daily fee, then estimate your subsidy percentage using our Child Care Subsidy calculator.
Take the fee, subtract the subsidy, and you've got your daily gap fee.
Subtract the daily gap fee from your after-tax daily pay. That's what one day of work leaves you.
Repeat for three, four and five days, remembering that four and five days draw on the higher 100-hour subsidy tier. You'll see what each pattern leaves you, so you can pick the one that fits your family.

If you're mapping out the wider return beyond the money, our guide to planning your return to work walks through the rest.

So, is going back to work worth it after childcare?

For most families, going back to work is worth it after childcare, once you count the Child Care Subsidy, your longer-term earnings, and your super. The first sum you run in your head is almost never the real one. When you work it out day by day, with the 3 Day Guarantee, your subsidy percentage and the tax on your returning income all in the picture, going back to work usually adds more than it first seems, and you can plan the days that suit your family with confidence.
