Types of Alimony

  • Rehabilitative: Most common. Provides support while the lower-earning spouse retains job skills, completes education, or re-enters the workforce. Duration: 1-5 years typically.
  • Permanent: Long marriages where one spouse can't become self-supporting due to age, disability, or having been out of the workforce for 15+ years.
  • Reimbursement: Compensates a spouse who supported the other's education or career advancement (e.g., putting them through medical school).
  • Bridge-the-Gap: Short-term (usually ≤2 years) to help transition from married to single life.

Common Formula Approaches

Some states use guideline formulas as starting points:

  • Simple approach: 30% of higher earner's gross minus 20% of lower earner's gross
  • Duration rule: Duration = 1 year of alimony per 3 years of marriage (varies)
  • Need-based: Close the gap to 40% of combined marital income

Factors Courts Consider

  • Standard of living during marriage
  • Age and physical/emotional condition of each spouse
  • Duration of marriage
  • Contributions as homemaker/parent
  • Each spouse's earning capacity and education
  • Marital misconduct (in fault states)

Disclaimer: Alimony is highly discretionary. Courts apply multi-factor tests with wide latitude. This calculator provides rough estimates only. Consult a licensed family law attorney in your state.

Frequently Asked Questions

How is alimony calculated?
There is no single federal formula. Most states use a multi-factor test weighing: length of marriage, income difference, standard of living, age and health, and contributions as a homemaker. Some states have formulas (e.g., 30% of higher earner's income minus 20% of lower earner's income). Courts have wide discretion.
Does fault affect alimony?
In fault states (about 30), adultery or other marital misconduct can affect alimony awards — a cheating spouse may receive less or none, or pay more. In no-fault states, fault doesn't matter. Consult an attorney about your state's approach.
Is alimony taxable?
For divorces finalized after December 31, 2018: alimony payments are NOT deductible by the payer and NOT taxable income to the recipient. This reversed decades of prior tax treatment. Divorces finalized before 2019 may still follow the old rules under the divorce agreement.
Can alimony be modified or terminated?
Yes. Courts can modify alimony if circumstances change significantly (job loss, major income change, cohabitation, remarriage). Permanent alimony typically terminates on the recipient's remarriage. Rehabilitative alimony ends at a set date or when the recipient becomes self-supporting.
