Wisconsin Child Support 2026

On $5,000 / $3,000 monthly gross · 2 children · Parent A 70% custody · Parent B pays, our engine estimates about $750 per month ($9,000 annually) for Wisconsin.

Wisconsin uses a percentage-of-income guideline model (NCSL). Our engine applies state-specific percentage math on this vignette. Wisconsin uses a flat percentage of the noncustodial parent's gross monthly income: 17% (1 child), 25% (2), 29% (3), 31% (4), 34% (5+). For income over $7,000/month a modified formula applies. Shared placement (each parent ≥25% of overnights/year) uses a separate calculation with both incomes.

Compared with Texas (~$750) and California (~$183) on the same vignette, Wisconsin sits at dense rank #1.
