How to Use the Georgia Child Support Calculator
Enter what you know and press Calculate Estimate. The calculator follows the steps in O.C.G.A. § 19-6-15: it adds both parents' incomes, looks up the basic obligation, splits it by income, adjusts for the noncustodial parent's parenting time, adds child care and health insurance, and applies the low-income limit.
- Enter each parent's gross monthly income as Parent A and Parent B.
- Choose the number of children (1 to 6) and the parent the children live with most of the time (the custodial parent).
- Enter the parenting days per year the children spend with the other (noncustodial) parent. Leave it at 0 if no parenting time is ordered. Georgia's calculator accepts at most 182.5 days for the noncustodial parent.
- Add monthly work-related child care and the child's health insurance premium, and say which parent pays them.
Your numbers are sent with the form, not placed in the page address, and this site does not store them. This is a planning estimate. A Georgia court decides the actual amount.
New Georgia Child Support Laws and Changes for 2026
Looking for new child support laws in Georgia for 2026? Georgia amended O.C.G.A. § 19-6-15 in 2024 (Act 618, the child support guidelines update). The statute history shows two effective dates:
- July 1, 2024: the updated basic child support obligation table, which now runs up to $40,000 of combined monthly adjusted gross income.
- January 1, 2026: the parenting time adjustment and the low-income adjustment. The official calculator's user guide confirms that both went into effect on January 1, 2026.
This calculator uses all of them. The parenting time adjustment reduces the noncustodial parent's share when that parent has court-ordered parenting time, and the low-income adjustment caps what a low-income parent can be ordered to pay at 19%, 24%, 25%, 26%, 27% or 28% of adjusted gross income for 1 to 6 children.
A change in the law does not automatically change an existing order. To use the new rules you generally have to ask the court to modify the order. Check the statute and the Georgia Child Support Commission for later updates.
How Georgia Calculates Child Support
Georgia uses the income shares model. Both parents' incomes are combined, a table gives the basic cost of raising the children, and each parent pays a share in proportion to income. Under O.C.G.A. § 19-6-15(b), the steps are:
- Find each parent's monthly gross income.
- Subtract allowed adjustments (half of self-employment tax, preexisting support orders for other children, and a court-allowed amount for other qualified children) to get adjusted gross income.
- Add the two adjusted incomes together.
- Find the basic child support obligation in the table, using the row closest to the combined income and the column for the number of children.
- Divide that amount between the parents by each parent's percentage of the combined income.
- Adjust the noncustodial parent's share for court-ordered parenting time (Schedule C).
- Add each parent's share of work-related child care and the child's health insurance premium (Schedule D). This is the presumptive amount.
- Apply any deviations the court allows (Schedule E), then the low-income adjustment if it applies.
The noncustodial parent normally pays their share to the custodial parent. Costs that the noncustodial parent already pays directly are credited against it.
The Georgia Basic Child Support Obligation Table
The table in O.C.G.A. § 19-6-15(o) lists the monthly basic obligation for 1 to 6 children, with rows every $50 from $800 to $40,000 of combined monthly adjusted gross income. A small sample for 2026:
| Combined adjusted gross income | 1 child | 2 children | 3 children |
|---|
| $3,000 | $562 | $857 | $1,036 |
| $5,000 | $887 | $1,341 | $1,610 |
| $7,500 | $1,109 | $1,656 | $1,963 |
| $10,000 | $1,285 | $1,906 | $2,242 |
| $15,000 | $1,682 | $2,471 | $2,879 |
| $20,000 | $2,053 | $2,998 | $3,470 |
If your combined income falls between two rows, the statute says to use the bracket most closely matched, and this calculator picks the nearest row. Above $40,000 a month the statute treats the parents as high-income and leaves the amount to the court, so the calculator stops there rather than guess.
Georgia Parenting Time Adjustment (2026)
From January 1, 2026, a noncustodial parent with court-ordered parenting time gets a reduction in their share of the basic obligation. Parenting time is counted in days averaged over a two-year period. Overnights count as days, and regular daytime periods count as their total hours divided by 24. The formula in § 19-6-15(g) is:
- Raise the noncustodial parent's days to the power of 2.5, and the custodial parent's days to the power of 2.5.
- Multiply the noncustodial days result by the custodial parent's dollar share of the basic obligation.
- Multiply the custodial days result by the noncustodial parent's dollar share.
- Subtract the second result from the first and divide by the sum of the two days results.
- Add that number to the noncustodial parent's share. The total is the adjusted share.
Check against the official user guide: in the Georgia Child Support Calculator User Guide's example, the noncustodial parent has 150 days and the custodial parent 215. Their shares of the basic obligation are $244.57 and $145.43. The formula gives $112.73 a month, the figure shown in the guide, and this calculator reproduces it.
The adjustment can reduce the noncustodial parent's share to zero. If there is no court order for parenting time, the adjustment is not used, so leave the days at 0.
Georgia Low-Income Adjustment
Under § 19-6-15(i.1), if a parent's monthly adjusted gross income is below the top of the Low-Income Adjustment Table for the number of children, that parent's obligation is the lesser of their presumptive amount and the table amount. The official calculator applies it automatically. At or below $1,500 a month, the cap is a percentage of income:
| Number of children | Cap on obligation at or below $1,500 a month | Table runs up to |
|---|
| 1 | 19% of the parent's adjusted income | $2,450 |
| 2 | 24% | see official table |
| 3 | 25% | see official table |
| 4 | 26% | see official table |
| 5 | 27% | see official table |
| 6 | 28% | $3,950 |
Between $1,500 and the top of the table, the cap comes from the table row nearest to the parent's income. The table's top income depends on the number of children: it ends at $2,450 for one child and runs to $3,950 for six.
Georgia Child Support Examples
In each example the children live with Parent A, and Parent B is the noncustodial parent. Amounts are rounded to the cent.
Example 1: One child, no parenting time ordered
A earns $4,000 and B earns $6,000 a month. Combined income is $10,000, and the table gives $1,285 for one child. B's share is 60%: $771.00 a month.
Example 2: Two children
Same incomes. The table amount is $1,906, and B pays 60%: $1,143.60 a month.
Example 3: 100 parenting days for the noncustodial parent
Same incomes and two children, with B having the children 100 days a year (A has 265). B's share falls from $1,143.60 to $153.32 a month.
Example 4: Child care
Example 2 plus $500 a month of child care paid by Parent A. B's 60% share adds $300: $1,443.60 a month.
Example 5: Low-income adjustment
A earns $1,500 and B earns $1,200 with two children. The presumptive amount is $345.78, but B earns $1,500 or less, so the cap is 24% of $1,200: $288.00 a month.
Example 6: Nearly equal time
Example 2 with B having 182 days (A has 183). B's adjusted share is $946.47 a month.
These are illustrations produced from the statute's formula, not court rulings.
Child Care, Health Insurance and Other Add-Ons in Georgia
- Work-related child care necessary for a parent's employment, education or vocational training is averaged to a monthly amount and divided between the parents in proportion to their incomes. The calculator adds the noncustodial parent's share.
- Health insurance premiums for the children are divided the same way. If only a family premium is known, the official guide suggests dividing it by the number of people covered and multiplying by the number of children in the case.
- A parent who pays these costs directly gets credit for the amount paid, which the calculator subtracts.
- Uninsured health care expenses are handled separately by the court and are not included here.
What This Georgia Estimate Does Not Include
- Adjustments to income: half of self-employment tax, preexisting support orders for other children, and the court's optional adjustment for other qualified children. Your gross income is treated as adjusted gross income.
- Deviations (Schedule E), such as high income, other health insurance, life insurance, travel or alimony.
- Combined incomes above $40,000 a month, which the court sets case by case.
- Uninsured medical costs, arrears, modification and enforcement.
- Cases with a nonparent custodian or split custody.

Frequently Asked Questions About Georgia Child Support
Is this the official Georgia child support calculator?
No. ChildSupportCalculator.xyz is an independent tool and is not affiliated with the State of Georgia. It follows O.C.G.A. 19-6-15. The official Georgia Child Support Calculator is run by the Georgia Courts and the Child Support Commission, and a judge decides the actual amount.
How is child support calculated in Georgia?
Georgia uses income shares. The parents' adjusted incomes are added, the basic child support obligation table gives the monthly cost for the number of children, and each parent pays a share in proportion to income. The noncustodial parent's share is then adjusted for parenting time, child care and health insurance are added, and the low-income adjustment is applied if needed.
What changed in Georgia child support in 2026?
The parenting time adjustment and the low-income adjustment went into effect on January 1, 2026. The updated basic child support obligation table, which runs up to $40,000 of combined monthly income, took effect on July 1, 2024. Existing orders do not change automatically.
Does Georgia use gross or net income?
Georgia uses gross income, minus allowed adjustments such as half of self-employment tax and preexisting support orders, to reach adjusted gross income. It does not use net income after taxes.
How does parenting time affect child support in Georgia?
Since January 1, 2026, a noncustodial parent with court-ordered parenting time receives a reduction in their share of the basic obligation. The formula raises each parent's days to the power of 2.5, so the reduction grows quickly as the days approach an even split. If no parenting time is ordered, the adjustment is not used.
Is there a Georgia child support calculator for joint custody or 50/50 time?
Yes. Enter up to 182 days for the noncustodial parent and the calculator applies the parenting time adjustment. The official calculator allows the noncustodial parent at most 182.5 days.
What is the Georgia low-income adjustment?
If a parent's adjusted income is below the top of the Low-Income Adjustment Table, their obligation is the lesser of the presumptive amount and the table amount. At or below $1,500 a month it caps support at 19%, 24%, 25%, 26%, 27% or 28% of income for 1 to 6 children.
What if our combined income is over $40,000 a month?
Georgia treats parents with combined adjusted gross income over $40,000 a month as high-income. The court sets the basic obligation, so this calculator does not show a figure.
Do I need to log in to use this calculator?
No. This site needs no account or login. The official Georgia calculator, according to its user guide, uses a user account with one-time-passcode verification. This site is not that tool and does not ask for any login.
Does this calculator include alimony, arrears or modification?
No. It estimates a new guideline amount only. Alimony, past-due support and modification depend on your case; check with the court or an attorney.
