How Alabama works it out
Alabama uses the income shares model: the schedule gives the basic child support obligation for the parents' combined monthly adjusted gross income, and each parent is responsible for their share.
Gross income from almost all sources counts, before taxes; the schedule already allows for income taxes. Means-tested benefits such as SSI and child support received for other children don't count. Alimony set in the same case isn't considered.
When the court orders shared physical custody about equally, the basic obligation is multiplied by 150% and each parent gets a credit of 50% of it; the parent with the higher net amount pays. Other parenting schedules are a reason a court may deviate, not part of the guideline amount.
