Behind the Number: How Georgia Calculates Child Support for Atlanta Parents
Ever wondered how a judge lands on a specific monthly figure for child support? It can feel like there must be a crystal ball involved, but the real answer is a worksheet. Georgia follows a set formula, and understanding it takes much of the mystery out of the process. Here is a plain-English tour from our Atlanta child support attorneys. Keep in mind that this is general information rather than legal advice, and every family’s facts are different.
Both Paychecks Count
Georgia uses an income shares model under O.C.G.A. § 19-6-15. Instead of looking at only one parent’s earnings, the court considers both. Gross income is defined broadly in subsection (f) and can include salary, bonuses, commissions, self-employment earnings, and other money coming in before taxes. Certain adjustments then apply, such as half of any self-employment taxes and preexisting support orders for other children.
The combined adjusted income is matched to a table to find the basic child support obligation. Each parent’s share depends on the percentage of the total income that parent contributes.
What Gets Added on Top
The table is only a starting point. The worksheet also accounts for:
- Health insurance premiums paid for the child
- Work-related child care costs
- Each parent’s court-ordered parenting time
- Possible deviations, such as extraordinary educational or medical expenses
If a court departs from the presumptive amount, it must explain why in writing and show how the change serves the child’s best interest.
What Changed for 2026
Senate Bill 454 revised the statute, so older articles may be out of date. Parenting time is now handled through a formula in which each parent’s court-ordered days are raised to the power of 2.5 as part of the adjustment. Under the revised language, parents whose combined adjusted gross income exceeds $40,000 per month are treated as high-income, up from the earlier $30,000 threshold. The statute also adds a low-income adjustment table, which lets a lower-earning parent’s obligation be measured against a separate chart.
Why Similar Families Can Land on Different Numbers
Two households with comparable incomes might still see different results. One may have steep child care bills, while the other has a child with significant medical needs. One may share parenting time nearly equally, while the other follows a more traditional schedule. The worksheet is designed to capture those differences, which is why accurate income and expense information matters so much.
It also explains why incomplete paperwork can create headaches. When pay stubs, tax returns, or records of business income are missing, the statute allows a court to impute income based on a parent’s work history, education, and local job market. Gathering documents early can help avoid surprises later, and it keeps the conversation focused on the facts of your family rather than guesses.
Support also does not last forever. In general, the duty continues until a child reaches the age of majority, dies, marries, or becomes emancipated, with limited exceptions for a child still in high school, and the same statute spells out how modifications work when circumstances change.
Numbers on a page can feel abstract until they land on your own budget. If you are wondering how the formula applies to your family, our Atlanta child support lawyers at Buckhead Family Law are glad to walk through it with you. Call us at 404-390-0000 or reach out online to set up a consultation.
