This calculator helps you estimate what you may pay or receive under the new child support formula from 1 April 2019 to 31 March 2020.

This calculator helps you work out the total number of nights in a 12-month period you have a child (or children) in your care. From 1 April 2015, the child support formula recognises a parent's ongoing daily care of their child (or children) when care is 28% or more of the time. Parents and non-parent carers, eg, grandparents, can receive child support when they provide ongoing daily care for a child (or children) for at least 35% of the time. This calculator helps you work out the total number of nights in a 12-month period you have a child (or children) in your care. The results are based on the information you've provided and don't guarantee recognised care will be accepted.
