Common Questions (FAQ)
Q: How does Wisconsin calculate child support?
Wisconsin applies a fixed percentage model. For example, the standard rates are approximately 17% of income for one child, 25% for two children, 29% for three children, 31% for four children, and 34% for five or more children.
Q: What if I have shared custody or split placement?
Wisconsin has different rules for shared placement (each parent has the child at least 25% of the time) or split placement (each parent has at least one child). This calculator assumes primary placement for simplicity, but actual court calculations may vary in shared cases.
Q: Is gross or net income used?
The Wisconsin guidelines generally start with gross income, but deductions and adjustments are allowed. Our tool uses net income for simplicity, providing a closer estimate of what you might actually pay or receive.
Q: Does this replace legal advice?
No. This calculator is designed for educational purposes and to give you a ballpark estimate. For official child support calculations or legal representation, you should contact a qualified family law attorney or the Wisconsin Department of Children and Families.
