How Michigan child support is calculated

The Michigan Child Support Formula (MCSF) calculates child support based on the net income of both parents. It considers all sources of income, the number of children, the number of overnights each parent spends with the child, and additional expenses like healthcare and childcare. The parent with more overnights often incurs more direct expenses, which are factored into the formula. The court reviews and may modify support agreements to ensure the child's best interests, considering the Michigan Child Support Formula.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Parenting time shifts

If the custody schedule changes significantly, support can be recalculated under Michigan guidelines.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.
