How Much Child Support for 2 Children?
Use this two-child scenario when you want a calculator-led estimate based on both parents’ incomes, care nights, and each child’s age.
Child support for two children is not a flat rate. The amount changes with both parents’ incomes, the number of nights each parent has the children, and whether the children are under 13 or 13+. This calculator scenario is for parents who want a practical estimate for a two-child case before they apply, negotiate, or check an assessment.
Quick answer
For 2 children, child support is worked out by applying each parent’s income share and care percentage to the 2026 costs of children table. In the example below, with Parent A earning $100,000, Parent B earning $60,000, and Parent A having 80 nights per year, Parent A pays about $10,606 per year, or $884 per month.
Worked example
This straightforward Formula 1 example uses two children under 13 and no relevant dependants, other child support cases, or non-parent carer.
Inputs
- Assessment year: 2026
- Children: 2 children, aged 8 and 11
- Parent A adjusted taxable income: $100,000
- Parent B adjusted taxable income: $60,000
- Parent A care: 80 nights per year
- Parent B care: 285 nights per year
Result
- Parent A child support income after the self-support amount: $68,954
- Parent B child support income after the self-support amount: $28,954
- Combined child support income: $97,908
- Parent A income percentage: 70.43%
- Parent A rounded care percentage: 21%
- Parent A cost percentage: 24%
- Costs of children: $22,842.20
- Estimated annual payment: $10,605.63
- Estimated monthly payment: $883.80
What changes the result
- The two-child table is separate from the one-child table, so the amount does not simply double.
- Ages matter because two children can both be under 13, both be 13+, or sit in the mixed-age table.
- Care nights affect the cost percentage once a parent has enough care for the formula to recognise direct costs.

Frequently asked questions
How much child support do you pay for 2 children?
There is no fixed amount for 2 children. The formula uses both parents’ adjusted taxable incomes, care percentages, the children’s ages, and the 2026 costs of children table.
Does child support double for 2 children?
No. Two children usually cost more than one child under the formula, but the amount does not simply double. The costs of children table has separate rates for 1 child, 2 children, and 3 or more children.
Does the age of the children matter for 2-child child support?
Yes. The table distinguishes children under 13 from children aged 13 or over. A two-child case with one older child may produce a different result from a case where both children are under 13.
Can care nights reduce child support for 2 children?
Yes. Care nights affect the cost percentage. Once a parent has at least regular care, the formula recognises that they meet some costs directly.
