Child support plays a vital role in helping children maintain stability after their parents separate or divorce. In Wisconsin, child support is calculated using statewide guidelines intended to ensure consistency while focusing on the best interests of the child.
Most child support orders are based on the “percentage standard,” which calculates support using the paying parent’s gross income and the number of children. When one parent has the child less than 25% of the time, support is set at approximately 17% of gross income for one child, 25% for two children, 29% for three, 31% for four, and 34% for five or more. However, courts may deviate from these guidelines if applying the standard would be unfair or inappropriate given the family’s circumstances.
When parents share placement, meaning each parent has the child at least 25% of the time, the calculation becomes more complex. Wisconsin uses what is often called the “shared-placement formula.” In these cases, the court considers both parents’ incomes, the percentage of time the child spends with each parent, and certain additional costs associated with maintaining two households for the child. Each parent’s support obligation is calculated, and the amounts are offset, typically resulting in the higher-earning parent paying support to the other. The goal is to fairly distribute the financial responsibility while recognizing that both parents are directly supporting the child during their placement time.
Child support orders are not necessarily permanent. A modification may be appropriate if there has been a substantial change in circumstances, such as a significant increase or decrease in income, a change in the placement schedule, or evolving needs of the child. Courts review these requests carefully to determine whether the existing order remains fair.
Parents often ask when child support ends. Generally, the obligation continues until the child turns 18. If the child is still attending high school or working toward a GED, support may continue until graduation or the child’s 19th birthday—whichever occurs first. Any unpaid support, however, remains enforceable until it is satisfied.
