Online estimator of child support
The Child Support calculator can be used to obtain an estimate of child support payable for a particular child support period. You can perform a simple calculation based solely on income details or you can add complexity by including additional information like variables of levels of care, age and other case related information.

Care Estimator
Helps customers estimate the level of care they have of a child. It may be useful before accessing the Child Support/FTB Estimator. It also helps determine whether you have enough care of a child to apply for child support or need to advise CSA about a change to care arrangements.
