Quick answer: Georgia child support modification requires a substantial change in either parent’s income and financial status or in the child’s needs. There is no percentage line. The same parent cannot file again within 2 years of a final order, with exceptions, and an involuntary loss of 25% or more of income has its own rule.
This Georgia child support modification calculator applies the rules in O.C.G.A. 19-6-15. Enter your current order and the amount the guidelines give today (you can get it from the Georgia child support calculator) and it shows whether the 2-year bar lets you file, the monthly difference and what it adds up to after the petition is served. Support that has already accrued is a judgment by operation of law and is not retroactively modified.

What does this modification calculator check?
The calculator checks whether the 2-year bar applies and whether an exception lets you file, shows the monthly and accrued difference, and notes the 25% involuntary-loss rule. It cannot decide whether your change is substantial; the judge or jury decides that. The months before service are the ones you cannot recover.
Frequently asked questions
What do I have to show to modify child support in Georgia?
A substantial change in either parent's income and financial status or in the needs of the child, proven so as to warrant the modification, and that the modification is in the child's best interest.
Can I file to modify Georgia child support again right away?
Not the same parent within 2 years of the final order on a previous petition, except when the other parent has not used court-ordered visitation, has used more than ordered, or the motion is based on an involuntary loss of income.
What if I lose my job in Georgia?
An involuntary termination, extended loss of hours, strike, loss of health, incarceration or similar adversity that causes a loss of 25% or more of income means the part of support tied to the lost income does not accrue from the date the petition is served.
Can Georgia change support that is already past due?
No. Each installment is a judgment by operation of law on and after its due date and is not subject to retroactive modification.
Does Georgia review child support orders?
In IV-D cases the agency must give notice of the right to request a review within 36 months of the order or the last review, and either party can ask for one.
