How Wisconsin calculates child support
Wisconsin's child support guidelines are established by Wis. Admin. Code § DCF 150.03. The state uses a Percentage of Income model, which applies a guideline percentage to the paying parent’s income, scaled by the number of children.
The result is the presumptive guideline amount — the starting point a Wisconsin court uses before considering deviation factors. The court-ready worksheet with the full line-by-line calculation, guideline-edition badge, and statutory citation is available in Aequis with a free 14-day trial.
Wisconsin child support FAQ
How is child support calculated in Wisconsin?
Wisconsin sets child support under its official guidelines (Wis. Admin. Code § DCF 150.03), which use a percentage of income approach. The guideline produces a presumptive monthly amount from the parents' incomes, the number of children, and inputs such as parenting time, childcare, and health insurance costs.
Is this the exact amount a Wisconsin court will order?
No. This is an informational estimate of the presumptive guideline amount. Courts can deviate based on statutory factors, and official worksheets may require inputs this calculator does not collect. Always verify against the official guidelines worksheet before relying on any number.
What income counts for child support in Wisconsin?
Guidelines generally start from each parent's gross income from most sources, with state-specific definitions, exclusions, and deductions. This calculator uses gross monthly income; consult Wis. Admin. Code § DCF 150.03 for what your state includes.
Do overnights affect child support in Wisconsin?
Many states adjust the obligation for parenting time once overnights pass a threshold, and this calculator applies Wisconsin's guideline treatment of overnights where the guideline provides one. The exact effect depends on the state's formula and the parents' incomes.
