The South Dakota support obligation schedule
Custody arrangement (including shared parenting adjustments)
Health insurance premiums for the child
Work-related childcare expenses

How Long Does a Child Support Modification Take in Louisiana?
Michigan calculates child support using the Michigan Child Support Formula (MCSF), which Michigan courts are required to use when setting or changing child support.
Michigan’s approach is based on an income-shares model, meaning the formula estimates what parents would have contributed toward the child if they lived together, then allocates responsibility between parents.
The calculation is based on:
Both parents’ incomes (used to determine each parent’s support share)
Number of children
A statewide support schedule/formula inputs (per MCSF)
Parenting time / overnights (Michigan applies a parental time offset when overnights can be determined)
Medical support (health insurance and ordinary medical considerations)
Work-related childcare expenses
Other adjustments and court-approved deviations under the MCSF
