How Michigan calculates child support
Michigan works out each parent's base support from the parents' combined net income using the General Care Support Table, then offsets the two amounts for parenting time.
Net income is all income minus actual income taxes, Social Security and Medicare, mandatory work deductions and the parent's own health coverage. This estimate works out taxes from gross income with standard assumptions.
Every overnight counts: the parental time offset weighs each parent's base support by their overnights raised to the power of 2.5. With equal time the parent with the higher income pays some support.
A parent with net income at or below $1,255 a month pays 10% of their income; just above that, a transition equation phases support in. Michigan has no minimum order.
The paying parent also pays their share of the ordinary medical amount ($200 a year for one child). The children's health insurance premium and child care are shared by each parent's percentage and offset.
A parent's net income is reduced by a multiplier for other children they support who aren't children of this relationship.
Above the table's top income level the top tier's percentages continue; courts may use discretion for very high incomes.
Percentage shares are kept to the hundredth of a percent and support amounts are rounded to whole dollars.
