One-child base rate at Michigan's median income
18% of $63,498, the Census ACS 2022 median household income for Michigan, divided across twelve months, level with the median state. An index for comparing states, not a case estimate: guidelines apply to the obligor's income, or to combined parental income under the Income Shares model, and a court sets the actual order. How this is derived.

Where Michigan's one-child starting rate sits
Each bar counts states with a published one-child base rate in that 3-point guideline band. Michigan is marked in its own band. Counts are exact from the 51-jurisdiction dataset.
Michigan's 18% published one-child base rate is higher than 19 of 51 recorded state rates. The comparison describes guideline starting percentages, not a complete child-support estimate.

Large Title IV-D caseload
Michigan in the heavy-caseload third
751,691 active cases put Michigan in the heaviest third by OCSE P-52 volume (#3).
Michigan carries 751,691 Title IV-D cases - a heavy-third book on OCSE P-52 volume. 43 jurisdictions share the Income Shares model with Michigan. Unlike capped states, the formula applies to full reported income before deductions - material on a large caseload. Nearest one-child rate peer: Alabama at 18% (Δ 0.0 pts). Michigan allows a parenting-time adjustment when the non-custodial parent exercises substantial overnight time. A percentage figure alone does not determine the dollar amount - compare Michigan to other guideline models →
On OCSE FY2023 tables, Michigan ranks #47 of 51 on order-establishment share and #3 by caseload volume (~$1,537 distributed per case, our calc on P-4/P-52). Source: HHS Office of Child Support Services, FY 2023 Preliminary Report.
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. Pair the schedule math with Michigan's thinner-than-most order-establishment share when reading enforcement.
Income Shares model. Michigan Child Support Formula uses schedules. Parenting time credit from 128+ overnights.
