Alabama Child Support Calculator
Estimate your child support obligations in Alabama using the income shares model. Understand how support is calculated, what factors matter, and what to expect. Updated for 2026.
Alabama uses the Income Shares Model under Rule 32 of the Alabama Rules of Judicial Administration. Both parents' adjusted gross incomes are combined to determine the Basic Child Support Obligation from the Schedule of Basic Child Support Obligations (Appendix to Rule 32). Each parent's share is proportional to their percentage of combined income. Adjustments are made for work-related child care expenses, health insurance premiums, and extraordinary medical expenses. Form CS-42 is the standardized worksheet. The guidelines are reviewed and updated at least every four years per Rule 32(G).
