How Wisconsin Calculates Primary Placement Child Support Rates
When the non-residential parent has less than 92 (less than 25% of the time) overnight visits with the child(ren), Wisconsin considers the case to be of primary placement to the residential parent. The child(ren)’s primary residence and supervision are provided by the residential parent, while the non-residential parent is entitled to visitation, which may or may not include overnights.
Wisconsin uses the standard percentage formula, set by our State Legislature, based on the number of kids to be in primary placement of a parent. The paying parent will make child support payments based on the following percentages:
- For 1 child, it's 17% of gross income
- For 2 children, it's 25% of gross income
- For 3 children, it's 29% of gross income
- For 4 children, it's 31% of gross income
- For 5+ children, it's 34% of gross income
In Wisconsin, the courts may use their discretion in evaluating other factors to increase or decrease monthly child support payments. Additionally, percentages vary based on low or high-income of either party.
