How child support is calculated in Alabama

The formula, the official tool, and the rules for low incomes and health insurance.

Checked against official sources: Oct 25, 2026.

Short answer

Alabama uses the income-shares model: both parents' incomes count, and each parent pays a share of the child's support. The court adds both parents' monthly gross income, finds the basic support amount for that income and number of children in the state schedule, then splits it by each parent's share of income.

Where the real number comes from in Alabama

The court adds both parents' monthly gross income, finds the basic support amount for that income and number of children in the state schedule, then splits it by each parent's share of income. Work-related child care and the children's health insurance are added and shared the same way.

Law: Ala. R. Jud. Admin. 32 (as amended effective May 1, 2022 and June 1, 2023)

We don't estimate Alabama's amount here: its formula uses both parents' incomes and other facts, and a home-made number could mislead you. The official tool gives the real starting number:

If the paying parent earns little in Alabama

A self-support reserve of $981 a month protects the paying parent's basic needs. If the result is under $50, the presumed minimum order is $50. A $0 order is presumed when the parent has no income and gets only means-tested benefits, or is jailed or institutionalized for more than 180 days in a row.

Law: Rule 32(C)(5)-(6)

State guidelines may not treat time in jail or prison as choosing not to work, when support is set or changed.

Law: 45 CFR 302.56(c)(3)

The child's health costs in Alabama

Every order must provide for the children's health care through private or public coverage and/or cash medical support. Coverage is normally required if a parent can get it through work at a reasonable cost; premiums and uncovered costs are shared by income.

Law: Rule 32(A)(4), (B)(7)

How this kind of formula works

The income-shares model looks up an amount for the parents' combined income, then splits it by each parent's share of that income. Parenting time and costs can change it.

Every state must have one set of child support guidelines, review them at least every 4 years, and use the guideline amount unless a written finding says it would be unjust.

Law: 45 CFR 302.56
