⚠️ Alimony is highly discretionary. Courts consider earning capacity, standard of living, age, health, and many other factors. This is a rough educational estimate only.

How Alimony Is Calculated

There is no single universal alimony formula — courts in most common-law jurisdictions have broad discretion. However, several states (including California and New York) use guideline formulas as starting points. A common rough guideline: 40% of the higher earner's net income minus 50% of the lower earner's net income.

Duration Guidelines

Alimony duration is often tied to marriage length. Common guidelines: short marriages (under 5 years): 30–50% of marriage length; medium (5–10 years): 40–60%; long marriages (10+ years): indefinite or 50–100% of marriage length in some states. Some jurisdictions (e.g., Massachusetts) use a strict formula tied to marriage length.
