Child Support Calculator in Michigan: What You Should Know
Michigan uses the Income Shares Model applied to net income, with a detailed Michigan Child Support Formula Manual that governs all calculations. Michigan's formula is notable for its handling of shared parenting time. The adjustment kicks in when the paying parent has 128 or more overnight parenting time overnights per year. Michigan also has specific provisions for medical support, including how health insurance premium costs are allocated between parents and how uninsured medical expenses are shared. Michigan updated its guidelines in 2021, adjusting the parenting time offset calculation to better reflect the actual costs of shared care.

Child Support in Michigan - Frequently Asked Questions
How is child support calculated in Michigan?
Michigan uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.
Can child support be modified in Michigan?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in Michigan typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in Michigan?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in Michigan?
Michigan does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in Michigan?
Child support in Michigan typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
