Florida Alimony Calculator: Durational Alimony Limits
Florida durational alimony ceilings from net incomes and marriage length: the lesser of need or 35% of the net-income difference, for up to 50%, 60% or 75% of the marriage.
In Florida, durational alimony can be no more than the lesser of the requesting spouse's reasonable need or 35% of the gap between the two net incomes, for no longer than half, 60% or 75% of the marriage by its length. At $8,000 and $3,000 a month net with $2,000 of need, the ceiling is $1,750 a month; after a 12-year (moderate-term) marriage it can last at most 86 months (7 years 2 months).

How This Calculator Works
Calculation methodology and assumptions
The calculator applies Florida Statutes §61.08 as amended in 2023. Amount: durational alimony is the requesting spouse's reasonable need or 35% of the difference between the two net incomes, whichever is less (§61.08(8)(c)); net income is figured as for child support under §61.30(2) and (3), so enter after-tax monthly income, not gross pay. Term: a marriage under 10 years is presumed short-term, 10 to under 20 years moderate-term, 20 years or more long-term (§61.08(5)), and a durational award may not run longer than 50%, 60% or 75% of the marriage respectively (§61.08(8)(b)); none is available after a marriage of less than 3 years (§61.08(8)(a)). These are ceilings. A Florida judge first has to find actual need and ability to pay (§61.08(2)) and then weighs the factors in §61.08(3), so an award can be lower or none at all.
Key State Information
Florida rewrote its alimony law in 2023 (ch. 2023-315): permanent alimony is gone from the list of forms, and the length of a durational award is capped by how long the marriage lasted. The court must also avoid leaving the paying spouse with significantly less net income than the recipient unless it finds exceptional circumstances in writing (§61.08(9)), and it may order life insurance or a bond to secure an award only on specific findings (§61.08(4)).
Example Calculation
A 22-year Florida marriage ends with the paying spouse netting $9,500 a month and the requesting spouse $4,000; the court finds $2,500 of reasonable monthly need.
35% of the $5,500 net-income difference is $1,925, which is less than the need, so durational alimony cannot exceed $1,925 a month. 22 years is a long-term marriage under §61.08(5), so the term cannot exceed 75% of 264 months.
Result: Ceiling: $1,925 a month for at most 198 months (16 years 6 months), leaving the payer $7,575 and the recipient $5,925 a month. A judge can award less, or nothing, after weighing the §61.08(3) factors.
Florida durational alimony ceilings by length of marriage
Same incomes in every row: $8,000 and $3,000 a month net, $2,000 of reasonable need. The amount ceiling is the lesser of that need and 35% of the $5,000 difference; only the length of the marriage changes the term.
| Marriage length | Presumed term | Longest durational award | Longest term | Highest monthly amount |
|---|---|---|---|---|
| 2 years | short-term | not available (under 3 years) | 0 months | $0 |
| 8 years | short-term | 50% of the marriage | 48 months (4 years) | $1,750 |
| 15 years | moderate-term | 60% of the marriage | 108 months (9 years) | $1,750 |
| 25 years | long-term | 75% of the marriage | 225 months (18 years 9 months) | $1,750 |
Computed by this page's calculator from Florida Statutes §61.08 (read 2026-10-20). Length runs from the wedding to the filing of the dissolution petition. A court may extend the term only on clear and convincing evidence of exceptional circumstances (§61.08(8)(b)).
The four kinds of alimony a Florida court can award
| Form | Purpose | Statutory limit |
|---|---|---|
| Temporary | Support while the divorce case is pending | No length or percentage limit in §61.08 |
| Bridge-the-gap | Identifiable short-term needs in moving from married to single life | At most 2 years; not modifiable in amount or length |
| Rehabilitative | Rebuilding skills or getting the education or training to become self-supporting | At most 5 years, and only with a specific written rehabilitative plan |
| Durational | Economic help for a set period | None after a marriage under 3 years; term up to 50/60/75% of the marriage; amount up to the lesser of need or 35% of the net-income difference |
Florida Statutes §61.08 (1), (6), (7) and (8). Permanent alimony is no longer one of the listed forms for petitions pending or filed on or after July 1, 2023 (§61.08(11)).

Our editorial standardsFrequently Asked Questions
How is alimony calculated in Florida?
Only durational alimony has a statutory cap on the amount: the requesting spouse's reasonable need or 35% of the difference between the two net incomes, whichever is less (§61.08(8)(c)). With $8,000 and $3,000 net a month the 35% cap is $1,750; with $2,000 of need, the ceiling is $1,750. Bridge-the-gap and rehabilitative awards have length limits but no percentage cap.
How long does alimony last in Florida?
Bridge-the-gap alimony lasts at most 2 years and rehabilitative alimony at most 5 years. Durational alimony may not exceed 50% of a marriage under 10 years, 60% of one from 10 to under 20 years, or 75% of one of 20 years or more, and is not available at all after a marriage under 3 years (§61.08(6)-(8)). A 12-year marriage allows up to 86 months (7 years 2 months).
Does Florida still have permanent alimony?
No, for cases pending or filed on or after July 1, 2023. Section 61.08 now lists temporary, bridge-the-gap, rehabilitative and durational alimony (§61.08(1)(a), (11)). Durational alimony ends on either party's death or the recipient's remarriage (§61.08(8)(a)).
Is alimony tax deductible?
Not for federal tax under divorce or separation instruments executed after 2018: the payer cannot deduct it and the recipient does not report it (IRS Topic 452). Florida has no personal income tax. Because Florida caps durational alimony on net income, enter after-tax figures.
