Raising kids on a mortgage.
Two-point-seven million Australian families are raising dependent kids, and for most the money question isn't one thing — it's the whole juggle at once: the mortgage, the childcare, the tax, the “can one of us go part-time?” This is the busiest segment on the map, where a small change to any number ripples through all the others.

This is the only segment paying the two biggest household bills at the same life stage — a mortgage near the $735,000 average owner-occupier loan and $14.35-an-hour childcare. The subsidy taper, not the headline pay, decides whether an extra day of work leaves you ahead.
The earning picture
Two incomes lift this segment above most of the map — but the totals flatter the reality. The band picture is a household number, not a per-person one: a couple can sit in a high band and still feel every rate rise, because the second income is doing double duty as childcare-payer.
The defining fact isn’t how much comes in — it’s how little slack sits between the mortgage and the childcare invoice. A $735,000 average owner-occupier loan (ABS Lending Indicators, Mar qtr 2026) meets $14.35-an-hour care (DoE, Sep qtr 2025) at the same life stage. The subsidy taper decides whether an extra day of work leaves the household ahead.
Once the youngest starts school, the childcare line collapses and the room to make extra repayments, salary-sacrifice, or rebuild the buffer opens up — the mirror image of the front-loaded squeeze. That is why “is the second income worth it?” is the question this segment asks most.
Where the money goes
Housing and childcare are the two levers, and for a few years they pull against each other. Read the shares as a household picture: the front-loaded years are the tight ones.
Once the youngest starts school the childcare line collapses and the room to make extra repayments, salary-sacrifice, or rebuild the buffer opens up. Until then, the childcare subsidy taper is the number that decides whether an extra day of work leaves the household ahead — exactly the sum the tools below are built to run.
Two incomes are now the norm
A generation ago, one earner and one carer was the default. Today two-in-three of these families run on two incomes — not always by choice, but because the mortgage assumes it.
That makes the “worth it?” maths on the second income the most valuable sum this household can run, because the answer swings on the childcare subsidy taper, not the headline pay.
