How alimony works in Wisconsin
Wisconsin 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: Wis. Stat. § 767.56 — Discretionary under statutory factors, but in long marriages Wisconsin courts start from an equal 50/50 division of total income before adjusting (LaRocque v. LaRocque).
