Florida has no official alimony calculator, so any online Florida alimony calculator is an estimate at best. Since July 1, 2023, Florida judges estimate durational alimony under Fla. Stat. 61.08 by comparing the spouses’ net incomes, capping the award at 35 percent of the difference, and limiting how long it lasts based on the length of the marriage.
This guide from Griffin Family Law, PLLC walks through the math a Duval County judge applies, including the need-and-ability-to-pay test, the three marriage-length categories, the duration caps, and a worked example with round numbers. If you want help applying these rules to your own situation, our Jacksonville alimony lawyer team can review your finances and give you a realistic range.
Key Takeaways
- Florida does not publish an official alimony calculator, and every online tool is an unofficial estimate that a judge can adjust.
- Before awarding any alimony, the requesting spouse must prove both an actual need and the other spouse’s ability to pay under Fla. Stat. 61.08(2).
- Durational alimony is capped at the lesser of the recipient’s reasonable need or 35 percent of the difference between the spouses’ net incomes.
- No durational alimony is available for a marriage that lasted less than 3 years.
- Durational alimony may not last longer than 50 percent of a short-term marriage (under 10 years), 60 percent of a moderate-term marriage (10 to 20 years), or 75 percent of a long-term marriage (20 years or more).
- Bridge-the-gap alimony is limited to 2 years, rehabilitative alimony to 5 years, and permanent alimony no longer exists for cases filed on or after July 1, 2023.
Is There an Official Florida Alimony Calculator?
No. Unlike child support, which follows a statutory guideline chart, Florida alimony has no state-issued formula or calculator. The 2023 reform (Senate Bill 1416) added hard caps and time limits to Fla. Stat. 61.08, but the judge still decides the final amount within those limits.
A calculator can estimate the statutory ceiling, but it cannot weigh the eight factors a judge must consider or predict whether a Fourth Judicial Circuit judge will award less than the maximum. Treat every figure in this article, and every online estimate, as a starting point rather than a prediction.
How Is Alimony Calculated in Florida After the 2023 Reform?
Florida calculates alimony in stages. A judge first decides whether alimony is appropriate, then chooses the type, and then sets the amount and length within the statutory caps. Here is the sequence a Jacksonville judge follows under Fla. Stat. 61.08.
Step 1: The need and ability-to-pay threshold
Under section 61.08(2)(a), the spouse asking for alimony must prove two things: that they have an actual need for support, and that the other spouse has the ability to pay it. If either piece is missing, the court must deny alimony and make written findings explaining why. This threshold stops many requests before any math happens.
Step 2: The eight statutory factors
If the threshold is met, section 61.08(3) requires the judge to consider the length of the marriage, the standard of living during the marriage, each spouse’s age and health, financial resources, earning capacity and employability, contributions to the marriage (including homemaking and child care), responsibilities for minor children, and any other factor needed to reach a fair result. The court must make written findings on these factors whenever it awards alimony.
Step 3: Choose the type of alimony
Section 61.08(1)(a) now lists four types: temporary, bridge-the-gap, rehabilitative, and durational. Permanent alimony was removed for any petition filed on or after July 1, 2023. Our post on Florida alimony reform explains the change in detail, and our guide to the different types of alimony in Florida explains when each one applies.
Step 4: Apply the amount and duration caps
Most couples ask about durational alimony, and it is the only type with a percentage formula. The amount is the lesser of the recipient’s reasonable need or 35 percent of the difference between the spouses’ net incomes. Duration is capped by the length of the marriage, which we cover next.
How Much Is Alimony in Florida? The 35 Percent Cap Explained
Under section 61.08(8)(c), durational alimony may not exceed the lesser of two amounts: what the receiving spouse reasonably needs or 35 percent of the difference between the spouses’ net incomes. The judge can award less than that ceiling but not more.
“Net income” for this purpose comes from Fla. Stat. 61.30(2) and (3), the same definitions used for child support. Gross income includes wages, bonuses, commissions, self-employment income, pensions, Social Security, interest, dividends, and rental income. Allowable deductions include income tax, FICA or self-employment tax, mandatory union dues, mandatory retirement contributions, the spouse’s own health insurance premiums, and court-ordered support actually paid for other children or a prior spouse. Alimony paid in the same case is not deducted.
One more guardrail appears in section 61.08(9): an award may not leave the paying spouse with significantly less net income than the receiving spouse, unless the judge makes written findings of exceptional circumstances.
A worked illustration with round numbers
The figures below are an illustration only. They are not a quote, and a judge may award less than the cap or deny alimony entirely based on need, ability to pay, and the statutory factors.
- Spouse A has a net monthly income of $9,000 after the Section 61.30 deductions.
- Spouse B has a net monthly income of $4,000.
- The difference is $5,000 per month.
- The 35 percent cap is $5,000 multiplied by 0.35, or $1,750 per month.
- If Spouse B’s documented reasonable need is only $1,400 per month, the award is capped at $1,400 because the statute takes the lesser of the two.
Because the cap moves with the income gap, it helps to think in ranges. A net income gap of $4,000 per month produces a ceiling of $1,400, and a gap of $6,000 per month produces a ceiling of $2,100. The final number in a Jacksonville case depends on what the financial affidavits and supporting documents prove.
How Long Does Alimony Last in Florida?
Duration depends on the type of alimony and the length of the marriage. Section 61.08(5) measures the marriage from the wedding date to the date the divorce petition is filed, not the date the divorce becomes final. It then sorts marriages into three categories:
- Short-term: less than 10 years
- Moderate-term: 10 years to less than 20 years
- Long-term: 20 years or longer
Durational alimony time limits
Under section 61.08(8), durational alimony is not available at all for a marriage that lasted less than 3 years. For longer marriages, it may not exceed 50 percent of the length of a short-term marriage, 60 percent of a moderate-term marriage, or 75 percent of a long-term marriage. For example, a 12-year marriage falls in the moderate-term category, so durational alimony could run up to 7.2 years (60 percent of 12). A judge may extend the term only with clear and convincing evidence of exceptional circumstances, such as the recipient’s age, disability, or care of a disabled child.
Bridge-the-gap and rehabilitative limits
Bridge-the-gap alimony covers identifiable short-term needs during the transition to single life and may not exceed 2 years under section 61.08(6). It cannot be modified. Rehabilitative alimony funds a specific plan to rebuild earning capacity, such as finishing a degree or a certification, and may not exceed 5 years under section 61.08(7). Our article on how long a spouse must pay alimony in Florida goes deeper into each timeline.
What Disqualifies You From Alimony in Florida?
The most common reason alimony is denied is failing the threshold test: either the requesting spouse cannot show a real need, or the other spouse cannot show an ability to pay. A marriage under 3 years rules out durational alimony entirely, although bridge-the-gap or rehabilitative support may still be possible in a short marriage.
Conduct can also matter. Section 61.08(1)(a) allows the judge to consider the adultery of either spouse and any resulting economic impact. A supportive relationship, meaning the requesting spouse lives with and shares expenses with a partner, is a factor under section 61.14(1)(b) that can reduce or end an award. For many military families, Fla. Stat. 61.046(8) excludes Veterans Affairs disability benefits from the definition of income, except for establishing an amount of support.
How Does the Alimony Process Work in Duval County?
Divorce cases for Neptune Beach, Jacksonville Beach, Atlantic Beach, and the rest of Duval County are filed with the Duval County Clerk at 311 W. Monroe St. in downtown Jacksonville and heard in the Fourth Judicial Circuit, which also covers Clay and Nassau counties. The court’s Family Court Services office publishes dissolution-of-marriage checklists and offers self-help resources, but it does not give legal advice on alimony amounts.
Every alimony claim rests on sworn financial affidavits and mandatory disclosure from both spouses. The quality of those documents often decides whether a spouse gets the statutory maximum, something less, or nothing.
Common Mistakes Our Attorneys See in Jacksonville Alimony Cases
At Griffin Family Law, PLLC, we see the same avoidable errors on both sides of alimony cases. Avoiding them is the best way to make any estimate more reliable.
- Running the calculation on gross pay. The 35 percent cap uses net income after the section 61.30 deductions, and gross figures overstate the ceiling.
- Guessing at the marriage length. The clock stops on the filing date, and a few months can move a marriage from short-term to moderate-term, or from 19 years to 20.
- Skipping the need analysis. A spouse who assumes the 35 percent number is automatic is often surprised when a judge awards less because the documented budget showed a smaller need.
- Ignoring the payor’s net income floor. An award that leaves the paying spouse with significantly less than the recipient will not survive without written findings of exceptional circumstances.
- Treating an online Florida alimony calculator as the law. These tools cannot apply the eight factors or predict a judge’s discretion.
How to prepare: gather two years of tax returns, six months of pay stubs, current statements for every account, and a line-item monthly budget. Bring documentation of health conditions, child care responsibilities, and any education or training plan if you expect to request rehabilitative alimony.
Frequently Asked Questions
Does Florida have an official alimony calculator?
No. Florida has no official alimony calculator and no statutory formula that produces a single number. Fla. Stat. 61.08 sets a ceiling for durational alimony and time limits by marriage length, but the judge decides the final amount within those limits.
How is alimony calculated in Florida in 2026?
A judge first confirms the requesting spouse has a need and the other spouse can pay. For durational alimony, the amount may not exceed the lesser of the recipient’s reasonable need or 35 percent of the difference between the spouses’ net incomes, and the length is capped at 50, 6,0, or 75 percent of the marriage, depending on whether it was short-, moderate-, or long-term.
Is permanent alimony still available in Florida?
No. For divorce petitions filed on or after July 1, 2023, Florida eliminated permanent alimony. The remaining types are temporary, bridge-the-gap, rehabilitative, and durational alimony.
How many years must you be married to get alimony in Florida?
Durational alimony requires a marriage of at least 3 years. Bridge-the-gap and rehabilitative alimony have no minimum marriage length in the statute, but the requesting spouse must still prove need and the other spouse’s ability to pay.
Can a judge award less than 35 percent of the income difference?
Yes. The 35 percent figure is a maximum, not a guarantee. The award is capped at the lesser of that amount or the recipient’s reasonable need, and the judge must also consider the eight statutory factors and may award less.
Does alimony end if the recipient remarries or lives with a partner?
Bridge-the-gap alimony ends automatically when the recipient remarries. The court may modify or terminate durational alimony based on a supportive relationship, and it may also consider a reasonable retirement by the paying spouse under Fla. Stat. 61.14.
