How alimony works in Hawaii
Hawaii 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: Haw. Rev. Stat. § 580-47 — Fully discretionary 13-factor statute with no formula; the transitional/rehabilitative/permanent categories come from case law.
