Estimating your Child Support payments

You may want to estimate what your Child Support payments might be. To help you, we have a range of tools available online. You do not have to work out your Child Support assessment yourself—we can work it out for you.

However, if you do not know the other parent's details, such as their income, you will not be able to use the estimator or worksheet.

Also, if you have two or more Child Support assessments the estimator will not work for you.

Child Support estimator

This service may give you an estimate of how much Child Support you might pay or receive. It cannot estimate your current Child Support payments or compare old and new estimates.

Use the estimator

Child Support family assistance estimator

This service may give you an estimate of:

  • how much Child Support you might pay or receive
  • the amount of family assistance you might receive, or
  • if you have less than 35 per cent care of your children, the amount of rent assistance you might receive

This service cannot estimate payments for every family situation.

Child Support worksheets

Some parents and non-parent carers may not be able to use the Child Support calculator or the Child Support-family assistance estimator. You may be able to use the following worksheets to estimate your Child Support payments.

Worksheet for the basic formula

Use these worksheets to estimate the Child Support payable for each child. If you have different care levels for the children, you will need to estimate the Child Support for each child separately.

Worksheet for parents who have relevant dependent children

Follow these steps to calculate the relevant dependent child amount for each child you and/or the other parent care for, from a second or subsequent family. When you have calculated this amount, transfer it to the basic formula worksheet.

Worksheet for parents who have two or more Child Support assessments

Follow these steps if you and/or the other parent have two or more Child Support cases. When you have calculated this amount, transfer it to the basic formula worksheet.
