What is CSA?

CSA stands for Child Support Agency, the former name of Australia's child support administration. In 2011, CSA was integrated into the Department of Human Services (now Services Australia). The name changed, but the formula and process remain the same.

Our CSA calculator uses the same 8-step formula that Services Australia uses to calculate child support payments:
