Free Florida Alimony Calculator
This Florida alimony calculator shows the most a court can award in durational alimony, and for how long, under the 2023 law.
Estimate only, not legal advice. This calculator applies the published Florida rules to the numbers you enter. A judge can order a different amount, and the result depends on how income is proven in your case. Settle101 is not a law firm. For advice on your situation, talk to a family-law attorney, legal aid or your state's child support agency.
The Florida alimony rules in 2026
- Need and ability to pay. The spouse asking for alimony must prove a need for it and that the other spouse can pay (s. 61.08(2)).
- Amount. Durational alimony is the lower of reasonable need or 35% of the difference in net incomes (s. 61.08(8)(c)). Net income follows the child support rules in s. 61.30(2)–(3).
- Length. The marriage length sets the limit (s. 61.08(5), (8)(b)).
- Fairness check. Alimony may not leave the paying spouse with significantly less net income than the receiving spouse without written findings of exceptional circumstances (s. 61.08(9)).
| Marriage length | Category | Max durational alimony |
|---|---|---|
| Under 3 years | Short | None |
| 3 to under 10 years | Short | 50% of marriage length |
| 10 to under 20 years | Moderate | 60% of marriage length |
| 20 years or more | Long | 75% of marriage length |
Worked example
After a 15-year marriage, one spouse nets $9,000 a month and the other $4,000. The difference is $5,000, so the most a court can award is $1,750 a month (35%), for up to 9 years (60% of a moderate-term marriage).
Other forms of alimony
- Temporary alimony while the case is pending.
- Bridge-the-gap for short-term needs moving to single life, up to 2 years, not modifiable.
- Rehabilitative to retrain or get credentials, up to 5 years, with a written plan.
What this calculator does not include
- Whether a court will find need and ability to pay, and the factors in s. 61.08(3).

How is alimony calculated in Florida?
Since 1 July 2023, durational alimony in Florida is the lower of the receiving spouse’s reasonable need or 35% of the difference between the spouses’ net incomes (s. 61.08(8)(c)). The court first has to find a need for support and an ability to pay.
Does Florida still have permanent alimony?

How long does alimony last in Florida?
Durational alimony may not exceed 50% of the length of a short marriage (under 10 years), 60% of a moderate marriage (10 to under 20 years) or 75% of a long marriage (20 years or more). Bridge-the-gap alimony is limited to 2 years and rehabilitative alimony to 5 years.
