Michigan Child Support Calculator

Michigan uses the income shares model. Michigan uses the Michigan Child Support Formula (MCSF), an income shares model that considers both parents' incomes, number of overnights, health care costs, child care costs, and other factors. The formula is updated periodically by the Michigan Supreme Court. The Friend of the Court calculates and recommends child support amounts; deviations from the formula require specific findings by the judge.

Gross income from all sources is typically used, including wages, salary, bonuses, commissions, self-employment income, rental income, investment income, Social Security benefits, unemployment benefits, and disability benefits. Courts may also impute income if a parent is voluntarily unemployed or underemployed.

Child support in Michigan generally continues until the child turns 18, or through high school graduation if the child is still in school. Some orders extend to age 19 or 21 depending on the state and circumstances (college support, special needs).

Yes, child support orders in Michigan can be modified when there is a substantial change in circumstances. Common reasons include significant income changes (job loss, promotion), changes in custody arrangement, changes in the child's needs, or changes in healthcare costs.

Michigan has enforcement mechanisms including wage garnishment, tax refund interception, license suspension (driver's and professional), bank account levies, contempt of court charges, and reporting to credit bureaus. Failure to pay can result in fines and jail time.
