How alimony works in Michigan
Michigan does not use a fixed statutory formula for alimony amounts. Judges weigh statutory factors — length of the marriage, each spouse's income and earning capacity, age and health, standard of living, and contributions to the marriage. Our calculator uses the AAML guideline formula (30% of payor's income minus 20% of recipient's) that attorneys commonly use for ballpark estimates.
Governing law: Mich. Comp. Laws § 552.23 — Entirely discretionary under a multi-factor case-law test that includes fault; the 'alimony prognosticator' software many Michigan attorneys use is unofficial with no legal force.
