About AusChildSupport
Child support calculations, made easier to understand.
AusChildSupport is an independent Australian service that produces an indicative child support Estimate from the information you enter.
Important boundaryAn Estimate is not a Formal Assessment. Services Australia issues Formal Assessments.
01 · Why it exists
A clearer way into a complicated formula.
Parents may need to understand the likely number before a discussion, mediation, application or appointment for professional advice.
The child support formula can be difficult to follow when income, care and family circumstances interact. The service exists to make a supported Estimate and its calculation path easier to inspect.
It offers a place to begin—not a decision about disputed facts, legal rights or what Services Australia will formally assess.

02 · Founder & operator
The work has a named person behind it.
I founded AusChildSupport to give parents a clearer way to understand an indicative child support figure before deciding what to do next. My background includes roughly three years working with the child support assessment process as a Services Australia child support officer.
I operate and maintain the service, and I am the person accountable for how its calculation approach is presented.

Three different things. Clearly separated.
Services Australia
A Formal Assessment
The official assessment issued by Services Australia. This service does not issue or change one.
Qualified professionals
Legal or financial advice
Advice about your rights, options or financial position. AusChildSupport does not provide it.
Contested income, care, eligibility, legal circumstances, enforcement, objections and official account action may require Services Australia or qualified professional advice.
