Guideline Estimate
Georgia uses the Income Shares model under O.C.G.A. §19-6-15. This simplified estimate applies approximate percentages of combined gross income and allocates by each parent's share. Actual orders use the state's online child support calculator and include adjustments for health insurance, childcare, and other expenses.
How Georgia calculates child support
Georgia uses the Income Shares model under O.C.G.A. §19-6-15. The Basic Child Support Obligation is based on the combined adjusted gross income of both parents and is divided between them in proportion to their incomes.
- Add both parents' gross monthly incomes to get combined gross income.
- Apply the guideline percentage for the number of children (19% for 1, up to 38% for 6).
- Allocate the obligation between parents by each parent's share of combined income.

Frequently asked questions
How long does child support last in Georgia? Generally until the child turns 18, dies, marries, or becomes emancipated; support may continue until age 20 if the child is still in high school.
Can the amount be modified? Yes — upon a showing of a material change in circumstances affecting the child's needs or either parent's ability to pay.
Is this the same as the state calculator? No. The Georgia Child Support Commission's online calculator is the official tool. This page is a simplified estimate and may differ from the official result.
