How alimony works in New Jersey
New Jersey 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: N.J.S.A. 2A:34-23 — Amount is discretionary under fourteen statutory factors; practitioners informally use roughly one-quarter to one-third of the income difference, but no formula is law.
