How Child Support is Calculated in Wisconsin
Child support payments in Wisconsin are calculated using the income percentage method. Payments are calculated as a fraction of the non-custodial parent’s income. The more children involved, the higher amount that will generally have to be paid.
Wisconsinites paying the most child support have high incomes and multiple children. The biggest recipients of child support are parents with primary care of multiple children where the paying parent has a high income.
The shared-placement formula is to be used at the discretion of the court. The court may use the shared-placement formula if the parents share the placement of their children at least 25% of the time - at least 92 days/year.
Child support is determined as a percentage of the payor’s income as set forth by Wisconsin law. For example, if a couple has three children together, and the children all live with one parent, the other parent is required to pay child support equal to 29 percent of his or her gross monthly income.Divergent Family Law
