How Wisconsin Calculates Child Support

Wisconsin calculates child support using the Percentage of Income model as defined in Wis. Stat. §49.0221 and DWD 40. The non-custodial parent pays a fixed percentage of their gross income based on the number of children: 17% for one child, 25% for two, 29% for three, 31% for four, 34% for five, and 37% for six or more children.

Wisconsin uses gross income for the standard calculation, which includes all income from all sources before any deductions. Shared placement adjustments are available when the parent has 25% or more overnight stays with the child. Serial family adjustments may reduce the income used for calculation if the parent has children from other relationships.

Wisconsin does not have a statutory income cap, but high-income payer provisions give the court discretion to adjust the amount. Low-income obligors may qualify for reduced percentages. Health insurance is ordered for the child separately from the base calculation.
