What is Alimony?
Alimony, also known as spousal support or maintenance, is a legal obligation where one spouse provides financial support to the other after separation or divorce. The purpose of alimony is to limit any unfair economic effects of divorce by providing income to a non-wage-earning or lower-wage-earning spouse.

Alimony is different from child support, which is specifically designated for the care and support of children. The amount and duration of alimony payments depend on various factors including the length of the marriage, the standard of living established during the marriage, and each spouse's financial situation.

There are several types of alimony that courts may award:

  • Temporary alimony: Support paid during the divorce proceedings
  • Rehabilitative alimony: Support to help a spouse become self-sufficient
  • Permanent alimony: Long-term or indefinite support
  • Reimbursement alimony: Repayment for expenses such as education or career training
  • Lump-sum alimony: One-time payment instead of periodic payments
How Alimony is Calculated
Alimony calculations vary by state, but most jurisdictions consider several common factors when determining the amount and duration of payments. Understanding these factors can help you get a clearer picture of what to expect.

The most common factors that influence alimony calculations include:

  • The income and earning capacity of both spouses
  • The length of the marriage
  • The standard of living established during the marriage
  • The age and health of both spouses
  • The educational background and employment skills of the receiving spouse
  • The contributions of each spouse to the marriage (including non-financial contributions)
  • The time needed for the receiving spouse to become self-sufficient

Many states use specific formulas to calculate alimony. For example, some states use a formula where 30% of the higher-earning spouse's income minus 20% of the lower-earning spouse's income equals the alimony amount. However, judges often have discretion to adjust these amounts based on the specific circumstances of each case.

Factors Affecting Alimony Payments
While our calculator provides a good estimate, it's important to understand that many factors can influence the final alimony determination. Courts consider numerous aspects when making alimony decisions:
  • Financial Resources: The court examines each spouse's income, assets, debts, and overall financial situation.
  • Earning Capacity: This includes education, skills, work experience, and employment opportunities for both parties.
  • Contributions to the Marriage: Both financial contributions and non-financial contributions (such as homemaking and childcare) are considered.
  • Standard of Living: The lifestyle established during the marriage is a benchmark for alimony considerations.
  • Marriage Duration: Longer marriages typically result in longer alimony durations, especially for marriages lasting over 10 years.
  • Age and Health: The physical condition, age, and health of both spouses can impact alimony decisions.
  • Child Custody Arrangements: The presence of children and custody arrangements can influence alimony determinations.
  • Tax Implications: Since the 2019 tax law changes, alimony is no longer tax-deductible for the payer or taxable income for the recipient.
Common Questions About Alimony
Can alimony be modified after it's been ordered?
Yes, alimony can typically be modified if there is a significant change in circumstances for either party. Examples include job loss, serious illness, retirement, or if the receiving spouse remarries or cohabitates with a new partner. The process usually requires filing a motion with the court and demonstrating that the change in circumstances is substantial and continuing.
How long does alimony last?
The duration of alimony varies widely depending on state laws and individual circumstances. For short-term marriages (under 10 years), alimony might last for half the length of the marriage. For medium-length marriages, it might last for a period that allows the recipient to become self-supporting. For long-term marriages (over 20 years), some states may award permanent alimony, though this practice is becoming less common. Many states now favor rehabilitative alimony with a specific end date.
What happens if alimony isn't paid?
If court-ordered alimony isn't paid, the recipient can take legal action to enforce the order. This might include wage garnishment, property liens, seizure of tax refunds, or even contempt of court charges which can result in fines or jail time. Many states have specific enforcement mechanisms for family support obligations. It's important to address inability to pay through proper legal channels rather than simply stopping payments.
Does remarriage affect alimony?
In most states, alimony automatically terminates when the recipient remarries. The paying spouse typically needs to file the appropriate court papers to stop payments once they learn of the remarriage. Some states also terminate or reduce alimony when the recipient cohabitates with a new partner, though the rules around cohabitation vary significantly by state and often require proving that the new relationship has reduced the recipient's financial needs.
Is alimony taxable income?
For divorces finalized after December 31, 2018, alimony is not tax-deductible for the payer and is not considered taxable income for the recipient. This was a significant change from previous tax law. For divorces finalized before 2019, the old rules still apply (payer can deduct payments and recipient must report them as income) unless the divorce agreement was modified after 2018 and specifically states that the new tax rules apply.
State-Specific Alimony Guidelines
Alimony laws vary significantly from state to state. Here's an overview of how some states approach alimony calculations:
California
New York
Texas
Florida
California uses a specific formula for temporary alimony: 40% of the higher earner's net income minus 50% of the lower earner's net income, adjusted for tax consequences. For permanent alimony, California courts consider factors like standard of living during marriage, earning capacity, contributions to education, and the duration of the marriage. Marriages lasting less than 10 years are typically awarded alimony for half the length of the marriage, while longer marriages may result in indefinite support.
New York uses a formula-based approach for post-divorce maintenance. The formula applies to income up to a cap (currently $184,000) and considers whether child support is being paid. For higher incomes, additional factors are considered. The duration is based on a sliding scale tied to the length of the marriage. For example, for marriages of 0-15 years, maintenance might last 15-30% of the marriage length; for 15-20 years, 30-40%; and for marriages over 20 years, 35-50%.
Texas has some of the most restrictive alimony laws in the country. To qualify for spousal maintenance, the marriage must have lasted at least 10 years, and the seeking spouse must prove inability to meet minimum reasonable needs. Even then, payments are capped at $5,000 per month or 20% of the payer's average monthly gross income, whichever is less. Duration is limited based on marriage length, with a maximum of 10 years of payments for marriages over 30 years.
Florida recognizes several types of alimony: bridge-the-gap, rehabilitative, durational, and permanent. The type awarded depends on factors like marriage length and each spouse's circumstances. Florida categorizes marriages as short-term (less than 7 years), moderate-term (7-17 years), and long-term (over 17 years). Permanent alimony is typically only awarded for long-term marriages when other forms of alimony are inadequate.
