Child Support Snapshot: Michigan
Michigan operates under the Income Shares model, one of 43 U.S. states using this framework. For a parent supporting one child, the base guideline applies roughly 18% of income, scaling to 26% for two children and 32% for three. That places Michigan at rank #17 of 51 states by single-child base percentage. Unlike capped states, there is no statutory income ceiling, the formula applies to the full reported income before deductions. Median household income here runs $63,498/yr.
Michigan ranks #35 of 51 reporting states on OCSE collection efficiency and #6 by caseload volume, see the case counts, collection rate, and paternity-establishment figures in the enforcement breakdown below.
Michigan allows a parenting time adjustment, which can materially reduce the base obligation when the non-custodial parent exercises substantial overnight time. A percentage figure alone doesn't determine the dollar amount, see how Michigan compares to other guideline models →
How Michigan Calculates Child Support
Michigan uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share. Its one-child base rate is in line with the national middle range.
Income Shares model. Michigan Child Support Formula uses schedules. Parenting time credit from 128+ overnights.
