Alabama Child Support Calculator

Estimate Alabama child support for 2026 using the Income Shares guideline model under Ala. R. Jud. Admin. Rule 32. Enter both parents' incomes and the parenting-time split to see what you may owe or receive.

Alabama follows the Income Shares model under Rule 32 of the Alabama Rules of Judicial Administration. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

Alabama uses the Income Shares model, and parenting time is not built into the basic schedule as an automatic per-overnight credit. Instead, extended visitation that goes beyond the standard schedule is treated as a deviation factor a judge may consider under Rule 32. This means more overnights with the paying parent do not lower the number by a fixed formula, but a parent can ask the court to deviate based on the actual time arrangement. The on-page calculator gives an estimate only, so confirm any visitation adjustment with the official worksheet or an attorney.

In Alabama the cost of health insurance premiums for the children is added to the basic support obligation and then prorated between the parents by their percentage share of combined income. The parent who pays the premium generally receives credit for the children's portion. Only the cost attributable to the kids, not the whole family plan, should be counted. Because the exact split depends on each parent's income share, use the official Rule 32 worksheet or a licensed attorney to confirm the final figure rather than relying on the estimate alone.

Work-related child care and daycare costs are added to the basic obligation in Alabama and prorated between both parents based on their share of combined income, under Rule 32. The care must be tied to a parent working or looking for work for it to be included. These add-ons sit on top of the basic guideline number, so they can meaningfully raise the total support amount. The calculator on this page is an estimate, so verify the actual child care share on the official Alabama worksheet or with an attorney.

An Alabama court can deviate from the guideline amount when applying the standard number would be unjust or inappropriate under Rule 32. Recognized reasons include other dependents in the home, extended visitation beyond the standard schedule, and extraordinary medical or educational expenses. The parent asking the judge to depart from the presumptive guideline figure carries the burden of showing why a deviation is warranted, and the court must state its reasons in writing. This page provides an estimate only and is not legal advice, so the official worksheet and a licensed attorney control the final order.

Frequently asked questions

How is child support calculated in Alabama?

Alabama uses the Income Shares model under Rule 32 of the Alabama Rules of Judicial Administration. The court first adds together both parents' monthly gross incomes. It then looks up the basic support obligation on the state guideline schedule for that combined income and the number of children. That obligation is split between the parents in proportion to each parent's percentage share of the combined income, so the higher earner generally pays a larger share. Add-ons like health insurance and work-related child care are layered on top. The calculator here is an estimate only, and the official Rule 32 worksheet or a licensed attorney controls the actual order.

Is there an official Alabama child support worksheet I have to use?

Yes. Alabama requires the Rule 32 child support guideline forms, including the official worksheet, and that worksheet is the controlling document the court relies on, not any online estimate. The forms are published through the Alabama Judicial System and the basic obligation comes straight from the state guideline schedule. You enter both parents' gross incomes, the children's health insurance premium, and work-related child care, and the worksheet prorates everything by income share. You can find the official forms at https://judicial.alabama.gov/library/forms. Use the calculator on this page only to get a rough idea, then complete the real worksheet or have an attorney do it.

What counts as income for Alabama child support?

Alabama bases support on gross income, and Rule 32 defines income broadly. It includes wages, salary, commissions, bonuses, net earnings from self-employment, rental income, pensions, unemployment benefits, workers' compensation, and Social Security. Means-tested public assistance such as TANF, SNAP, and SSI is excluded and is not counted against a parent. If you are self-employed, reasonable business expenses can be deducted to reach your net earnings before they go into the formula. Because bonuses and self-employment income can be complex, the figure you enter into this estimate should be confirmed on the official worksheet or with an attorney before it goes in an order.

How are bonuses, overtime, and self-employment income treated in Alabama?

Alabama counts recurring income from many sources, so bonuses and commissions are generally included in gross income under Rule 32 when they are a regular part of what a parent earns. Self-employment income is counted as net earnings, meaning you can subtract reasonable and necessary business expenses before the number enters the formula. Courts look at the real economic reality rather than just a tax return, so aggressive write-offs may be added back. Overtime that is consistent can also be considered. These categories are easy to get wrong, so use this page only as an estimate and confirm variable income on the official worksheet or with a licensed attorney.

How are health insurance, daycare, and uninsured medical costs split in Alabama?

In Alabama these are treated as add-ons under Rule 32. The children's health insurance premium and work-related child care are added to the basic support obligation and then prorated between the parents by their percentage share of combined income. Extraordinary medical or educational expenses can also be added and split the same way. Uninsured or out-of-pocket medical costs are commonly divided by that same income-share percentage. Because each add-on changes the total, the estimate here may differ from the final order. Complete the official Alabama worksheet or work with an attorney to pin down how each cost is divided in your case.

When can an Alabama child support order be modified?

Either parent can ask the court that issued the order to modify it, or request an administrative review through the Alabama Department of Human Resources, Child Support Services Division. Under Rule 32, a fresh calculation that differs from the existing order by 10 percent or more is generally presumed to be a material change of circumstances that justifies modification. Job loss, a significant income change, or a change in the children's needs can trigger that variance. Modification is not automatic, so you must file and prove the change. Run the numbers as an estimate here, then confirm them on the official worksheet or with an attorney before petitioning.

When does child support end in Alabama?

In Alabama, support generally runs until the child reaches age 19, which is the state's age of majority, or graduates from high school, whichever comes later. It can continue for a disabled adult child whose disability began before majority. Support also ends earlier if the child dies, marries, or otherwise becomes emancipated. Support does not just stop on its own in every situation, so you may need to address termination with the court or with the Department of Human Resources, Child Support Services Division. Any past-due amounts, or arrears, still remain owed. This page is an estimate only, so confirm timing details with the official worksheet or an attorney.
