Wisconsin — Percentage of Income Model
Wisconsin uses the Percentage of Income model. Support is calculated as a flat percentage of the non-custodial parent's gross income: 17% for one child, 25% for two, 29% for three, 31% for four, 34% for five or more. Shared placement (25%+ overnights) uses a more complex formula considering both parents' incomes.
