Georgia Child Support: How It's Calculated

Child support in Georgia isn't a guess or a flat percentage — it runs on a formula. Here's a plain-English guide to how Georgia calculates child support, what counts as income, how to change an order, and how an Atlanta family lawyer can help.

Georgia uses the "income-shares" model

Child support is one of the core issues in Georgia family law, and it is set both in a divorce and between parents who were never married. Georgia calculates child support on the idea that a child should receive the same proportion of parental income they'd have gotten if the family were together. The basic steps:

1. Add both parents' gross incomes together to find combined income.
2. Look up the Basic Child Support Obligation — a dollar figure from a state table based on that combined income and the number of children.
3. Divide it between the parents in proportion to each parent's share of the combined income.
4. Apply adjustments — for example, for health insurance premiums and work-related child care — to reach each parent's final obligation.

Georgia provides an official Child Support Worksheet to run this calculation. Because small input differences change the result, getting the numbers right matters.

What counts as income

"Gross income" is broad in Georgia. It generally includes wages, salary, commissions, bonuses, overtime, self-employment income, and many other sources. In some situations — for example, if a parent is voluntarily unemployed or underemployed — a court can consider that parent's earning ability rather than just their current paycheck. Making sure income is counted correctly (on both sides) is often where a support case is won or lost.

Deviations from the standard amount

The worksheet produces a presumptive amount, but Georgia allows deviations — up or down — when the standard figure wouldn't be fair or in the child's best interest. Examples can include high parenting-time costs, extraordinary medical or educational expenses, or other special circumstances — one reason the underlying child custody arrangement can affect the support figure. A judge has to explain a deviation on the record.

Changing a child support order

Child support isn't frozen forever. If there's been a substantial change in circumstances — a significant change in either parent's income, or in the child's needs — a parent can petition the court to modify the amount. Georgia has rules about how often you can seek a modification, with some exceptions for things like an involuntary income loss.

Enforcement — what happens if support isn't paid

Georgia takes unpaid support seriously and has strong enforcement tools, including wage garnishment, intercepting tax refunds, suspending driver's and professional licenses, and contempt of court. The state's Division of Child Support Services (DCSS) can help establish and enforce orders. If you're owed support — or being pursued for it — an attorney can help you respond.

How an Atlanta family lawyer helps

A lawyer makes sure the worksheet inputs are accurate (especially income and the adjustments), argues for or against a deviation where one is warranted, and handles modifications and enforcement. Whether you're setting support for the first time or dealing with a change years later, getting the calculation right protects both you and your child. Good questions to ask: their experience with Georgia child support and your county's courts, how they see your numbers, and the cost.

Frequently asked questions

How is child support calculated in Georgia?

Georgia uses an "income-shares" model. Both parents' gross incomes are combined to find a basic support amount from a state table, then that amount is divided between the parents in proportion to their incomes. Adjustments are made for things like health insurance and work-related child care. [General information — not advice about your case.]

What counts as income for Georgia child support?

Gross income is broad — it generally includes wages, salary, commissions, bonuses, self-employment income, and many other sources. The court can also consider a parent's earning ability in some situations. An attorney can help make sure income is calculated correctly.

Can child support be changed in Georgia?

Yes. A parent can ask the court to modify child support when there's been a substantial change in circumstances, such as a significant change in income or in the child's needs. There are rules about how often and when you can seek a modification.

What happens if a parent doesn't pay child support in Georgia?

Georgia has strong enforcement tools, including wage garnishment, interception of tax refunds, license suspension, and contempt of court. The state's Division of Child Support Services (DCSS) can help enforce orders, and an attorney can pursue or defend enforcement actions.

Is there an official child support calculator for Georgia?

Yes — Georgia provides an official Child Support Worksheet that runs the income-shares calculation. Be careful with unofficial online estimators: because small differences in the inputs change the result, a worksheet filled in with inaccurate income or adjustments can produce a number well off from what a court would actually order.

Does the number of children change child support in Georgia?

Yes. The Basic Child Support Obligation is a figure drawn from a state table based on two things: the parents’ combined gross income and the number of children being supported. That figure is then divided between the parents in proportion to each one’s share of the combined income.

Can a judge order more or less than the Georgia child support formula?

Yes. The worksheet produces a presumptive amount, but Georgia allows deviations up or down where the standard figure wouldn’t be fair or in the child’s best interest — for example, high parenting-time costs or extraordinary medical or educational expenses. A judge has to explain any deviation on the record.
