Based on 2025 MCSF (Net Income & Parental Time Offset)
*Ordinary Medical Expense (OME) of ~$457/child/year is automatically calculated and added. Do not include standard copays in "Health Insurance".
Michigan uses the 2025 Michigan Child Support Formula (MCSF). This sophisticated model factors in both parents' net incomes and the exact number of overnights each parent spends with the child.
Unlike states with a simple "20% cliff," Michigan uses a continuous curve (Equation: Overnights^2.5) to gradually shift support as parenting time increases. Every additional overnight reduces the payer's obligation slightly.
The 2025 formula presumes parents spend about $457 per child annually on minor medical costs. This is built into the base support calculation so you don't have to exchange receipts for small copays.
Net Income is your Gross Income from all sources minus federal, state, and local income taxes, FICA (Social Security/Medicare), and mandatory payments like union dues or employer-required retirement contributions.
Yes. You can receive a deduction for children from other relationships if you are paying court-ordered support for them, or if they live with you (Additional Children Adjustment).
