Georgia Child Support Formula
This page explains Georgia’s current calculation order, not just the headline rule. The main Georgia trap in 2026 is skipping straight from the table to a final number without separating add-ons, current adjustments, and any true remaining deviation issues.
Quick Facts
Income Shares model
Georgia still starts with both parents’ incomes under O.C.G.A. § 19-6-15.
July 1, 2024 update
Georgia’s current Basic Child Support Obligation table changed on July 1, 2024.
January 1, 2026 workflow
Parenting Time Adjustment and Low-Income Adjustment now sit inside the current worksheet flow.
Online commission calculator
Georgia commission FAQs say the old Excel calculators were retired on September 30, 2018.
Child care and children’s health insurance
These are still among the most common reasons the final transfer amount changes.
Separate deviation findings
After the current adjustment workflow is applied, any remaining deviation still needs proper findings.
Georgia Formula Sequence
Georgia begins with monthly gross income for both parents. If this starting input is wrong, every later percentage and table lookup will be wrong too.
The next job is to move from gross income into the adjusted income base recognized by O.C.G.A. § 19-6-15 before support shares are assigned.
Once both adjusted incomes are known, Georgia uses the combined figure and the number of children to identify the Basic Child Support Obligation from the current statewide table.
Georgia then applies each parent’s income percentage so the presumptive support amount reflects each parent’s proportional financial capacity.
Work-related child care and children’s health insurance are two of the most common amounts layered onto the base table result.
Under current Georgia materials, parenting time and low-income treatment should be checked as adjustments before you move into any remaining deviation analysis.

Use This With Other Georgia Tools
Support pages should route back into the core Georgia calculators and legal explainers.

Frequently Asked Questions
How does the Georgia child support formula start?
It starts with both parents’ monthly gross incomes under the Income Shares model, then moves through the statutory adjustments before the current BCSO table is used.
What changed most recently in the Georgia formula?
The two checkpoints are July 1, 2024 for the updated BCSO table and January 1, 2026 for the current Parenting Time Adjustment and Low-Income Adjustment workflow.
Are parenting time and low-income issues still best described as deviations?
Not first. Current Georgia commission materials treat those as part of the updated adjustment workflow. If a support issue survives after that, then you evaluate whether a remaining deviation analysis is necessary.
Should I use an older Georgia Excel calculator?
No. Georgia Child Support Commission FAQs state that the old downloadable Excel calculators were retired on September 30, 2018. The online commission calculator is the current official worksheet path.
When should I use this formula page instead of the calculator page?
Use this page when you need to understand the order of operations or explain why a worksheet result moved. Use the Georgia calculator page when you are ready to open the official tool and work through the live worksheet.
