Georgia Child Support Calculations

The purpose of child support is to ensure that even if the parents have ended their relationship, they each still have an obligation to financially support their child. While a parent's child support obligations usually end when the child turns 18, if the child has certain mental or physical disabilities, those obligations may extend past the age of 18. It's also possible for a parent to be required to help with college expenses. In Georgia, the Georgia Child Support Commission has several duties related to child support, including establishing and regularly reviewing child support guidelines and maintaining the Georgia Child Support Calculator.

Georgia Child Support Calculations at a Glance

Legal research should always involve reading the actual language of a statute. But, oftentimes statutes are written in "legalese," which can take some time to parse through and understand. For this reason, it can be helpful to also read a summary of statutes that's written in plain English. The following table gives a basic overview of the laws that relate to child support calculations in Georgia, as well as links to relevant statutes.


Georgia Code, Title 19, Chapter 6, Section 19-6-15 (Child Support Guidelines)

Overview of Process for Calculating Child Support

Monthly child support is calculated as follows:

  1. Determine the monthly gross income of both the custodial and noncustodial parent.
  2. Adjust each parent's monthly gross income by deducting: (a) half of the amount of self-employment taxes, (b) preexisting orders, and (c) theoretical child support for qualified children (if allowed by the court).
  3. Add the parents' adjusted income together.
  4. Find the basic child support obligation on the child support obligation table (located in the same statute).
  5. Divide the combined adjusted income into each parent's adjusted income to determine each parent's pro rata percentage of the basic child support obligation.
  6. Add the expense of health insurance and work-related child care costs to find the adjusted child support obligations amount.
  7. Determine the amount of child support for the custodial and noncustodial parent resulting in a monthly payment to the custodial parent by assigning or deducting credit for actual payments for work-related child care costs and health insurance from the basic child support obligation.
Deviations from Presumptive Amount of Child Support

Deviations added to or subtracted from the presumptive amount of child support can be applied if supported by application of the "best interest of the child" standard. Deviations may include (but are not limited to) the following:

  • High income;
