Alimony amounts vary widely by state and depend on the paying spouse's income, the length of the marriage, and the receiving spouse's needs
There is no single alimony number. A court in California might order $2,000 a month for a 15-year marriage where one spouse earned $120,000 and the other earned nothing. A court in Texas might order $1,500 for similar facts. A court in New York might order $3,500. The difference comes down to state law, which sets different formulas, caps, and duration rules.
What matters to the court is not a national average but three things: how much the paying spouse actually earns, how long the marriage lasted, and whether the receiving spouse can support themselves. A judge has discretion within those bounds, which is why two similar cases in the same courthouse can produce different numbers.
This guide explains how states calculate alimony, what income counts, and what the range typically looks like. It does not predict what a specific court will order—that requires a lawyer who knows your state's rules and your local judge's patterns.
Key Takeaways
- Most states use a formula based on the paying spouse's gross income, the receiving spouse's income, and the length of the marriage, but the formula itself varies by state.
- Temporary alimony (paid during divorce proceedings) is usually lower than permanent alimony (paid after the divorce is final), and both may end when the receiving spouse remarries or reaches retirement age.
- Income for alimony purposes typically includes salary, bonuses, and self-employment earnings, but states differ on whether to count investment income, rental income, or benefits like Social Security.
- States with statutory formulas—like Florida, Texas, and Massachusetts—produce more predictable numbers than states where judges have broad discretion.
- The paying spouse's ability to pay and the receiving spouse's need both matter; a court will not order alimony that would leave the paying spouse unable to cover basic living expenses.
How states calculate alimony: formula-based versus discretionary
About half of U.S. states use a statutory formula to calculate alimony. Florida, for example, multiplies the paying spouse's monthly gross income by a percentage that depends on marriage length: roughly 5% for marriages under 10 years, up to 7.5% for marriages over 20 years. If the paying spouse earns $6,000 a month and the marriage lasted 15 years, the formula suggests around $375 to $450 monthly, though the judge can adjust this if the receiving spouse has income or significant need.
Other states—including New York, California, and many others—give judges discretion to set alimony based on factors like the standard of living during the marriage, each spouse's earning capacity, and the age and health of both parties. This means two judges in the same state can reach different conclusions for similar cases.
Texas has no permanent alimony at all; it allows only "spousal maintenance" for marriages over 10 years, capped at the lesser of $5,000 monthly or 20% of the paying spouse's gross income. Some states limit alimony duration to half the length of the marriage. Others allow permanent alimony only in long marriages or when the receiving spouse cannot work.
What income counts toward alimony
Courts typically count gross income—salary before taxes—plus bonuses, commissions, and self-employment earnings. A spouse who owns a business must usually report net business income (revenue minus legitimate business expenses) rather than gross revenue.
States diverge on whether to count investment income, rental income, retirement account withdrawals, or benefits like Social Security or disability payments. Some states include all of these; others exclude Social Security or treat it separately. A few states impute income to a spouse who is deliberately underemployed—for example, a spouse who quit a $80,000 job to earn $30,000 may be treated as if they still earn $80,000.
Child support is usually deducted from income before alimony is calculated. If a paying spouse earns $5,000 monthly and pays $800 in child support, the court typically calculates alimony on the remaining $4,200.
Temporary alimony during divorce versus permanent alimony after
Temporary alimony (called "alimony pendente lite" in some states) is paid while the divorce is still pending. It is usually lower than permanent alimony because it is meant to keep the receiving spouse afloat during the divorce process, which typically lasts 6 to 18 months depending on the state and whether the divorce is contested.
Permanent alimony is ordered at the final divorce judgment. Despite the name, it is not always truly permanent. Most states allow it to end when the receiving spouse remarries, when either spouse reaches a certain age (often 65 or 67), or when the paying spouse retires. Some states allow modification if circumstances change significantly—for example, if the paying spouse loses their job or the receiving spouse's income increases substantially.
A few states use "reimbursement alimony" to repay a spouse who worked to put the other through school, or "rehabilitative alimony" to support a spouse for a set period while they retrain for work. These are usually lower and shorter-term than permanent alimony.
Real-world ranges by marriage length and income
These are approximate ranges based on typical state formulas and judicial practice. They are not predictions for any specific case.
| Marriage Length | Paying Spouse Income | Typical Monthly Range | Notes |
|---|---|---|---|
| Under 5 years | $60,000/year | $200–$400 | Short marriages often result in lower or no alimony; depends on whether receiving spouse can work. |
| 5–10 years | $60,000/year | $300–$600 | Formula-based states produce more predictable numbers; discretionary states vary widely. |
| 10–20 years | $100,000/year | $1,000–$2,500 | Marriage length and income both increase the amount; receiving spouse's need and earning capacity matter. |
| Over 20 years | $150,000/year | $2,500–$5,000+ | Long marriages and higher income produce higher awards; permanent alimony is more likely. |
These ranges assume the receiving spouse has little or no income. If the receiving spouse earns $40,000 a year, the court typically reduces the alimony amount or may order none at all. The ranges also assume the paying spouse has no other dependents; child support obligations reduce the amount available for alimony.
Factors that increase or decrease alimony
Courts increase alimony when the receiving spouse is older, in poor health, or has been out of the workforce for years and faces barriers to employment. A spouse who gave up a career to raise children or support the other spouse's education is more likely to receive higher alimony. Courts also consider the standard of living during the marriage; if the couple lived lavishly, the receiving spouse's need to maintain that standard may increase the award.
Courts decrease alimony when the receiving spouse has earning capacity or is already employed, when the marriage was short, or when the paying spouse has limited income or other dependents. A paying spouse who is already paying substantial child support may receive a reduction in alimony. Some judges also consider whether the receiving spouse contributed to the breakdown of the marriage, though this factor is less common and varies by state.
How alimony ends or changes
Permanent alimony typically ends when the receiving spouse remarries, cohabits with a partner in most states, or reaches an age set by state law (often when the paying spouse reaches full retirement age). It also ends if either spouse dies. Some states allow the paying spouse to request modification if they experience a substantial change in circumstances—job loss, serious illness, or retirement—but the burden is usually on the paying spouse to prove the change was involuntary and significant.
The receiving spouse can request an increase if the paying spouse's income rises substantially or if the receiving spouse's circumstances change (for example, loss of employment). Modification requests require going back to court and presenting evidence of the changed circumstances. The process typically takes several months and involves attorney fees.
Frequently Asked Questions
Is alimony the same as child support?
No. Child support is for the children and is usually mandatory when there are minor children. Alimony is for the ex-spouse and depends on factors like marriage length and earning capacity. Both can be ordered in the same divorce, and child support is typically calculated first and deducted from income before alimony is set.
Can alimony be modified if my income changes?
Yes, but only if the change is substantial and involuntary. Losing a job or becoming disabled usually qualifies. Voluntarily taking a lower-paying job typically does not, unless you can show the change was necessary. You must file a modification request with the court and provide evidence of the change.
What happens to alimony if I remarry?
In most states, alimony ends when ready upon remarriage of the receiving spouse. Some states also end alimony if the receiving spouse cohabits with a partner. The paying spouse must file a motion to terminate alimony; it does not stop automatically, so you need to notify the court.
Do I have to pay alimony if my ex remarries?
No. Alimony ends when the receiving spouse remarries in all 50 states. If you are still paying after your ex remarries, contact your attorney or the court to file a motion to terminate alimony. You may be able to recover overpayments, depending on your state.
How is alimony different in short marriages versus long ones?
Short marriages (under 5 years) rarely result in permanent alimony; courts may order temporary support or none at all. Long marriages (over 20 years) often result in permanent or long-term alimony, especially if the receiving spouse left the workforce. Marriage length is one of the strongest predictors of alimony amount and duration.
