Free USA Alimony Calculator — Spousal Support Estimation

USA alimony (spousal support/maintenance) is court-ordered financial support paid by the higher-earning spouse to the lower-earning spouse during or after divorce. Unlike child support, there is no single federal formula — each USA state sets its own alimony guidelines. Some states (California, New York, Illinois) use specific formulas, while others leave amounts to judge discretion. Common USA formulas calculate alimony as 30-40% of the income difference between spouses. Duration typically correlates with marriage length: short marriages (under 10 years) receive temporary support, while long marriages (20+ years) may result in permanent alimony. The 2017 Tax Cuts and Jobs Act eliminated the alimony tax deduction for agreements after 2018.

🇺🇸 USA Alimony Laws

There are four types of USA alimony: temporary (during divorce proceedings), rehabilitative (for education/training), durational (fixed period after divorce), and permanent (indefinite, typically for long marriages or disability). The 2017 TCJA changed alimony taxation: for divorces finalized after December 31, 2018, alimony is no longer tax-deductible for the payer or taxable to the recipient. This significantly changed the economics of alimony negotiations in the United States.

❓ Frequently Asked Questions

How is USA alimony calculated?
It varies by state. Common USA formulas use 30-40% of the income difference between spouses. Factors include: marriage length, each spouse income and earning potential, lifestyle during marriage, age, health, and contributions (including homemaking).
Is USA alimony tax-deductible?
For divorces after December 31, 2018: NO. The 2017 Tax Cuts and Jobs Act eliminated the alimony deduction. For pre-2019 divorces, the old rules still apply (deductible for payer, taxable for recipient) unless modified.
How long does USA alimony last?
It depends on marriage length and state law. General USA guidelines: marriages under 10 years may receive support for 1/3 the marriage length. 10-20 year marriages: 1/2 the marriage length. 20+ years: potentially indefinite.
Can I avoid paying USA alimony?
Alimony is not guaranteed in USA divorces — it depends on income disparity, marriage length, and other factors. A prenuptial agreement, shorter marriage, similar incomes, or the recipient earning capacity can reduce or eliminate it.
