Child Support in Alabama: How It's Calculated
Alabama uses the Income Shares Model to determine child support obligations. This guide walks through how the formula works, what factors Alabama courts consider, and how to modify or enforce an order — with links to official Alabama resources.
Income Shares Model in Alabama
Alabama uses the Income Shares Model, which combines both parents' gross incomes to determine a total child support obligation. The court then divides that obligation between the parents in proportion to each parent's share of the combined income.
Alabama's Schedule of Basic Child Support Obligations (found in Rule 32 of the Alabama Rules of Judicial Administration) sets the baseline amount based on combined income and number of children. Adjustments are made for health insurance premiums and work-related childcare costs. Significant parenting time — generally 25 overnights per month or more — can trigger a shared physical custody adjustment.
Key Factors Alabama Courts Consider
- Both parents' gross monthly income (wages, salary, self-employment, rental income, etc.)
- Number of children covered by the order
- Cost of the child's health insurance premium (employer-provided or private)
- Work-related childcare expenses
- Parenting time split — significant overnight time with the paying parent can reduce the obligation
- Extraordinary expenses such as private school tuition or ongoing medical costs
- Existing child support obligations for children from other relationships

Step-by-Step: How Alabama's Formula Works
Here is how Alabama applies the Income Shares Model to calculate a child support obligation, step by step:
1. Determine each parent's income
Alabama starts by calculating each parent's income — gross income (before taxes). The specific definition of income is set by Income Shares Model.
2. Combine incomes and find the basic obligation
Both parents' incomes are combined and compared to Alabama's child support schedule. The schedule produces a basic child support obligation based on combined income and the number of children.
3. Add health insurance and childcare costs
Health insurance premiums paid for the child and work-related childcare expenses are added to the basic obligation before it is divided between parents.
4. Divide proportionally based on income share
The total obligation is allocated between the parents in proportion to each parent's share of combined income. The parent with the higher income share bears a larger portion of the obligation.
5. Apply parenting time credits
Parenting time split — significant overnight time with the paying parent can reduce the obligation parenting time — generally 25 overnights per month or more — can trigger a shared physical custody adjustment.
