Types of Alimony

Rehabilitative

Temporary support to help the lower-earning spouse gain education, training, or work experience to become self-supporting.

PermanentYour estimate

Ongoing support until the recipient remarries, either spouse dies, or the court modifies the order. Typically for long-term marriages.

Durational

Support for a set period of time, often tied to the length of the marriage. Cannot exceed the length of the marriage in most states.

Factors Courts Consider

Income Disparity

The gap between each spouse's earning capacity and actual income.

Marriage Length

Longer marriages generally result in longer and higher alimony awards.

Age & Health

Older recipients or those with health issues may receive more support.

Education & Skills

The recipient's ability to become self-supporting through employment.

Childcare Duties

Custodial responsibilities that may limit earning capacity.

Marital Standard of Living

Courts aim to maintain a similar standard of living post-divorce.

Contributions to Marriage

Homemaking, supporting a spouse's career, or education contributions.

Marital Misconduct

Some states consider fault (adultery, abuse) when determining alimony.

Disclaimer: This calculator provides rough estimates for informational purposes only and does not constitute legal advice. Actual alimony awards are determined by courts based on numerous factors specific to each case, including but not limited to the factors listed above. State laws change frequently, and judges have significant discretion in setting support amounts and duration. Child support is calculated separately and may affect alimony. Tax treatment of alimony varies (post-2018 federal tax law eliminated the deduction for the payor). Consult with a qualified family law attorney in your jurisdiction for advice on your specific situation.

Frequently Asked Questions

How is alimony calculated?▾

Alimony formulas vary by state but generally consider both spouses' income, the length of the marriage, standard of living during marriage, each spouse's earning capacity, and contributions to the marriage.

How long does alimony last?▾

Duration depends on marriage length and state laws. Short marriages (under 10 years) typically result in rehabilitative alimony lasting a few years. Long marriages (20+ years) may result in permanent alimony. Many states use a percentage of marriage length.

Is alimony tax-deductible?▾

For divorces finalized after December 31, 2018, alimony is no longer tax-deductible for the payer and is not taxable income for the recipient under federal law. Pre-2019 agreements may still use the old rules.
