How Child Support Is Calculated in Georgia
Georgia calculates child support using the Income shares model on combined gross income established under O.C.G.A. § 19-6-15. This is a statutory formula that leaves limited room for judicial discretion on the base calculation amount, ensuring consistency and predictability for families across the state.
The Formula
Basic obligation from published schedule. Each parent's share = pro rata based on income percentage. Mandatory parenting time adjustment scaled to overnight share (SB 454).
The calculation begins with determining each parent's net disposable income, which includes virtually all sources of income minus taxes, mandatory payroll deductions, and certain hardship deductions. The court then applies the statutory formula using the time each parent has primary physical responsibility for the children and the applicable income allocation brackets.
Beyond the base formula amount, Georgiarequires additional contributions for mandatory add-on expenses. These typically include childcare costs necessary for the custodial parent's employment or education, uninsured healthcare expenses for the children, and in some cases, educational and travel costs. These add-ons are split between parents in proportion to their respective incomes.
