How Child Support Is Calculated in Wisconsin
Factors That Affect Child Support in Wisconsin
Technical details and legal basis
Wisconsin uses the Percentage of Income model (Wisconsin DCF 150 (Percentage of Income Standard)) to calculate child support. This means child support is based on a set percentage of the non-custodial parent's gross income, with the percentage increasing for more children.
Important Notes for Wisconsin
- • Wisconsin uses the Percentage of Income model, applying flat percentages to the non-custodial parent's gross income: 17% for 1 child, 25% for 2 children, 29% for 3, 31% for 4, and 34% for 5 or more.
- • Gross income includes wages, salary, tips, commissions, bonuses, self-employment income, rental income, and other income sources before taxes.
- • Wisconsin has a shared placement formula that applies when the non-custodial parent has the child for at least 25% of overnight placement (92 nights per year).
- • The court may deviate from guidelines for high-income payers, where applying the standard percentage would exceed the child's reasonable needs.
Example Calculation
Scenario: Non-custodial parent earns $5,000/month gross income, 2 children.
Step 1: Determine gross monthly income: $5,000
Step 2: Apply the guideline percentage for 2 children: 25%
Step 3: Calculate: $5,000 × 25% = $1,250/month
