Alabama calculates child support under Rule 32 of the Alabama Rules of Judicial Administration, using an income-shares model built around the CS-42 worksheet family. The rule sets a $981 self-support reserve for the paying parent and a $50 monthly floor below which an order generally won’t go. Parents who split parenting time close to evenly can instead use the CS-42-S worksheet, and a separate credit exists for Social Security, VA, or railroad benefits the children already receive on the paying parent’s record.

Frequently asked questions

What guideline does Alabama use for child support?

Rule 32 of the Alabama Rules of Judicial Administration, most recently amended effective June 1, 2023. It’s an income-shares model with a published 596-row schedule (revised May 1, 2022) run through the CS-42 worksheet.

Is there a minimum child support amount in Alabama?

Yes — Rule 32 sets a $50/month minimum order, and a $981/month self-support reserve is protected for the paying parent before support is calculated on the remainder.

How does 50/50 custody change the Alabama calculation?

Parents who share parenting time close to evenly use the CS-42-S worksheet instead of the standard CS-42 form, which applies a different formula for that arrangement.

Will an Alabama judge always order the exact calculated amount?

The Rule 32 figure is a presumptive amount, not a mandatory one — a judge can deviate from it, and this calculator produces an estimate only, not legal advice.
