How Child Support is Calculated in Michigan


Child support payments in Michigan are calculated using the income shares method. Payments depend on the combined incomes of the parents as well as the number of children. A larger combined income or more children usually means greater payments.

The amount paid or received by an individual parent also depends on income and parenting time percentages.

  • If your income percentage (your share of combined income) is higher than your care percentage (share of parenting time), you are probably the payer.
  • The receiver is normally the parent with a care percentage above their income percentage.

Michiganians paying the most child support have high incomes and rarely look after their children. On the flipside, the biggest receivers are parents who (a) work little (b) have their kids nearly all the time and (c) have a high earner as the other parent.

Michigan child support guidelines are based on the monthly net income of both parents and the time a child spends with each one. The court reviews child support agreements to make sure the guidelines are applied correctly, and the payment amount is appropriate.

Child support in Michigan is based on a formula that takes into account the parents incomes, the number overnights with the children, child care expenses for children 12 and under, and health insurance premium expenses for the children. Reaching a child support figure is often a contentious issue between parents when there is no agreement on the number of overnights or when a parent’s income is not straightforward.
