How Child Support Is Calculated in Michigan
Factors That Affect Child Support in Michigan
Technical details and legal basis
Michigan uses the MCSF Marginal Rate model (Michigan Child Support Formula (MCSF)) to calculate child support. The MCSF applies marginal rate brackets to combined net income, with decreasing percentages at higher income levels. Each parent's obligation is proportional to their share of combined income.
Important Notes for Michigan
- • Michigan uses the MCSF with marginal rate brackets — support percentages decrease at higher income levels.
- • The MCSF applies base support percentages to combined net income, then each parent pays their proportional share.
- • Michigan protects the obligor's self-support at the federal poverty level ($1,255/month).
- • Parenting time offsets reduce the obligation based on the number of overnights each parent has.
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
