How Arizona works it out
Arizona uses the income shares model: the schedule gives the basic obligation for the parents' combined monthly income, and each parent is responsible for their share.
Gross income from almost all sources counts, before taxes. Spousal maintenance paid is deducted and maintenance received is added; support paid for other children is deducted, and a parent's income may be reduced for other children living with them.
The parenting time table gives a percentage for the number of parenting-time days a year, from 20 days. That percentage of the basic obligation (plus the older-child adjustment) is subtracted from the share of the parent who has the time. With essentially equal time both parents get the top percentage and the parent with the larger amount pays.
