Assumptions in this estimate
  • For 2026–27, using your family’s adjusted taxable income for the financial year. Children are counted at their age for the whole year.
  • Children aged 16 to 19 are in full-time secondary study. Single parents get Part B until the end of the year their youngest child turns 18.
  • Child support you receive (the maintenance income test), shared care, Multiple Birth Allowance, the Energy Supplement and newborn payments aren’t included.
  • Rent Assistance is 75c for each $1 of private rent over $207.34 a fortnight ($306.60 for couples), up to $263.06 with 1 or 2 children and $297.36 with 3 or more. It’s paid only above the base rate of Part A.
  • The Part A supplement ($970.90 a child) needs family income of $80,000 or less. Part A can be reduced if your children’s immunisations aren’t up to date.

How the calculator works

  1. Part A is paid for each child. You get the most when family income is $69,131 or less; above that it falls by 20c for each $1, but not below the base rate, until family income passes $123,078, when it falls by 30c for each $1.
  2. Part B is paid for the family, depending on the youngest child’s age. For couples, it depends on the lower earner’s income: it falls by 20c for each $1 over $7,154.
  3. Rent Assistance is added to Part A if you rent privately and get more than the base rate.
  4. Fortnightly amounts are the yearly rates divided by 365, rounded to the cent, then times 14, the way Services Australia works them out.
