Start with O.C.G.A. § 19-6-15. In Georgia, Georgia uses the Income shares and measures income as gross income. Georgia’s statutory calculator uses adjusted gross income of both parents, a basic child support obligation from the schedule, and parenting-time adjustments. Health insurance, work-related childcare, and deviations are entered on the child support worksheet required in every case. That is the question this guide answers for how child support is calculated. Support generally ends when Support generally ends at 18, or until high-school graduation if the child turns 18 while still enrolled, not past age 20 in typical cases. Modification: Material change in either parent’s income and financial status or the child’s needs; recalculation of the worksheet typically anchors the motion.
Statutory framework and guideline model
Georgia's child support system is built around O.C.G.A. § 19-6-15. Under the income shares, Georgia’s statutory calculator uses adjusted gross income of both parents, a basic child support obligation from the schedule, and parenting-time adjustments. Health insurance, work-related childcare, and deviations are entered on the child support worksheet required in every case.
Federal law requires every state to maintain presumptive guidelines and to review them at least every four years (42 U.S.C. § 667). Confirm the latest Georgia schedule or worksheet before relying on any online calculator.
How child support is calculated in Georgia
- Identify each parent's guideline income using gross income as defined in O.C.G.A. § 19-6-15 and the accompanying worksheets or administrative rules.
- Apply the income shares — whether that means a combined-income schedule, an obligor percentage table, or a Melson-style self-support reserve plus primary obligation.
- Allocate add-ons such as health insurance premiums, unreimbursed medical expenses, and work-related child care according to Georgia practice.
- Consider parenting time adjustments where the guidelines or case law authorize a credit or shared-custody formula.
- Test for deviation if a strict guideline result would be unjust or inappropriate on the record.
Online calculators can illustrate ranges, but only the controlling statute, guidelines, and court findings produce an enforceable order.
How the Georgia rule applies
Apply the Georgia authorities in order. The facts are simplified so the statute and the standard are visible.
Two parents in Georgia need a presumptive child-support figure and may have facts that justify a departure.
- Measure guideline income as gross income under O.C.G.A. § 19-6-15.
- Apply the Income shares: Georgia’s statutory calculator uses adjusted gross income of both parents, a basic child support obligation from the schedule, and parenting-time adjustments. Health insurance, work-related childcare, and deviations are entered on the child support worksheet required in every case.
- Test deviation: Statutory non-specific and specific deviations include high income, special expenses, travel, and other parent’s low income, among others listed in § 19-6-15.
- If circumstances later change: Material change in either parent’s income and financial status or the child’s needs; recalculation of the worksheet typically anchors the motion.
The enforceable number is the Georgia guideline result under O.C.G.A. § 19-6-15, plus any deviation findings. Division of Child Support Services uses income withholding, contempt, tax intercepts, and license suspension.
Deviation from the guidelines
Statutory non-specific and specific deviations include high income, special expenses, travel, and other parent’s low income, among others listed in § 19-6-15.
When a court departs from the presumptive amount, Georgia practice generally requires findings that explain why the guideline figure is unjust or inappropriate and what amount better serves the child's needs. Those findings matter on appeal and in later modification proceedings.
Modification of child support
Material change in either parent’s income and financial status or the child’s needs; recalculation of the worksheet typically anchors the motion.
A parent seeking a change typically must show that circumstances after the prior order make the existing award inequitable. Common triggers include job loss, substantial income changes, a new parenting-time schedule, emancipation of a child, or extraordinary medical needs. Retroactivity and temporary relief rules are statute-specific — check O.C.G.A. § 19-6-15 and local family-division procedures.
Enforcement in Georgia
Division of Child Support Services uses income withholding, contempt, tax intercepts, and license suspension.
Interstate cases often implicate UIFSA. Income withholding, contempt, license suspension, and tax-refund intercept remain core tools nationwide, but the Georgia child support agency and clerk of court procedures control day-to-day collection.
When child support ends
In Georgia, Support generally ends at 18, or until high-school graduation if the child turns 18 while still enrolled, not past age 20 in typical cases. Orders may extend for disability, secondary education, or other statutory grounds where the statute allows. Always read the judgment language — agreed orders sometimes set a different end date or require a notice of emancipation.
