Alimony Calculator

There is no single national formula. Common methods include the one-third rule (1/3 of the income difference), the AAML formula (30% of payer's income minus 20% of recipient's), and various state-specific guidelines. Judges consider factors like marriage length, standard of living, age, health, and earning capacity.

Duration typically depends on the length of the marriage. Short marriages (under 5 years) may have alimony lasting 30% of the marriage length. Long marriages (20+ years) may result in permanent alimony. Most states cap alimony duration at half to equal the length of the marriage.

For divorces finalized after December 31, 2018, alimony is no longer tax-deductible for the payer or taxable income for the recipient under the Tax Cuts and Jobs Act. For pre-2019 divorces, the old rules may still apply unless the agreement is modified.
