Wisconsin Child Support Calculator

Wisconsin uses the percentage of income model. Wisconsin uses a Percentage of Income model under Wis. Stat. § 767.511 and DCF 150 administrative rules. The paying parent's gross income is multiplied by a fixed percentage based on the number of children: 17% for 1 child, 25% for 2 children, 29% for 3 children, 31% for 4 children, and 34% for 5 or more children. Shared placement adjustments apply when the payer has 25% or more placement time. A high-income payer formula applies when gross monthly income exceeds $7,000, with reduced percentages above that threshold and further reductions above $12,500/month.

Gross income from all sources is typically used, including wages, salary, bonuses, commissions, self-employment income, rental income, investment income, Social Security benefits, unemployment benefits, and disability benefits. Courts may also impute income if a parent is voluntarily unemployed or underemployed.

Child support in Wisconsin generally continues until the child turns 18, or through high school graduation if the child is still in school. Some orders extend to age 19 or 21 depending on the state and circumstances (college support, special needs).

Yes, child support orders in Wisconsin can be modified when there is a substantial change in circumstances. Common reasons include significant income changes (job loss, promotion), changes in custody arrangement, changes in the child's needs, or changes in healthcare costs.

Wisconsin has enforcement mechanisms including wage garnishment, tax refund interception, license suspension (driver's and professional), bank account levies, contempt of court charges, and reporting to credit bureaus. Failure to pay can result in fines and jail time.
