Example 1 of the basic child support formula

Amanda earns income in her full-time job. For 2006-07, the taxable income shown on her payment summary was $42,000. Phil receives income support from Centrelink. In 2006-07, his income was $15,550.

They have two children—Fran is 14 and Jack is 11. They don’t have any other relevant children.

The children stay with Amanda during school holidays and some weekends, which equates to about 80 nights a year (between 14-34 per cent care). Phil has the children the rest of the time.

Step 1: Each parent's child support incomes Amanda Phil
Work out each parent's adjusted taxable income $ 42,000 $ 15,660
Deduct the self-support amount from each parent's adjusted taxable income - $18,252 * - $18,252 *
Deduct a relevant dependent amount - $ 0 - $ 0
Deduct a multi-case allowance amount - $ 0 - $ 0
Each parent's child support income = $ 23,748 = $ 0

Step 2: Parents’ combined child support income Amanda Phil
Add each parent’s child support income together $ 23,748 $ 0
Combined child support income = $ 23,748

Step 3: Each parent’s income percentage Amanda Phil
Each parent’s child support income $ 23,748 $ 0
Divide each parent’s child support income by the combined child support income 1 0
Multiply this amount by 100 x 100 x 0
Each parent’s income percentage = 100 % = 0 %

Step 4: Each parent’s care percentage Amanda Phil
Each parent’s care percentage 21 % 79 %

Step 5: Each parent’s cost percentage Amanda Phil
Each parent’s cost percentage 24 % 76 %

Step 6: Each parent’s child support percentage Amanda Phil
Each parent’s income percentage 100 % 0 %
Deduct each parent’s cost percentage 24 % 76 %
Each parent’s child support percentage + 76 % - 76 %

Step 7: The costs of the children Fran and Jack
Total cost of all the child support children (using Table C) = $ 6,293
Cost of each child (divide the total cost by the number of children) = $ 3,147

Step 8: How much child support Amanda pays to Phil Amanda
The parent's child support percentage + 76 %
Multiply this percentage by 100 x 100
Multiply this amount by the cost of each child x $ 3,147
Child support payable for each child per year = $ 2,392

* The self-support amount for child support periods starting in 2008 is $18,252. This amount is indexed each year. You will be advised in writing when this amount changes.
