If you’re heading into a Miami divorce and money is part of the conversation, you’ve probably searched “how is alimony calculated in Florida.” Fair question — and the honest answer is: it’s not a single number you plug into a calculator. It’s a two-part test, followed by a formula, followed by a list of factors a judge weighs against your specific facts.
Here’s what changed the game: since July 1, 2023, Florida no longer allows permanent alimony. Every case filed today is governed by a rewritten Florida Statute 61.08, and understanding it is the difference between guessing at a number and actually knowing what to expect. Let’s take a closer look and break it down.
Step 1: Need and Ability to Pay
Before any math happens, a judge must first answer this two-part question: does the spouse asking for alimony actually have a documented financial need, and does the other spouse have the financial ability to pay?
If either answer is no, the claim for alimony is denied — the analysis stops there. This may mean, for example, that a spouse asking for alimony may have an actual need, but the other spouse may not have the financial ability to pay.
This is why financial affidavits, tax returns, and pay records matter so much from the very start of a case. Weak documentation on either side can decide the outcome before the formula ever comes into play.
Obviously, simply being married does not, by itself, entitle anyone to automatically receive alimony.
Step 2: Which Type of Alimony Fits Your Case?
Assuming need and ability to pay are both established — both answers to the question in Step one is “Yes” — the court chooses from four remaining types of alimony under Florida law:
- Temporary alimony — support during the divorce case itself, ending at final judgment. Receiving alimony during the litigation itself does not mean that the spouse will not receive additional alimony after the end of the case.
- Bridge-the-gap alimony — short-term help for an identifiable transition need to assist the spouse receiving to make a financial transition from being married to being single, capped at 2 years.
- Rehabilitative alimony — funds a specific, documented plan for education or job training, capped at 5 years.
- Durational alimony — periodic payments for a set period of time; the closest replacement for the old permanent award.
Which type applies depends heavily on how long you were married, measured from your wedding date to the date the divorce petition was filed:
| Marriage Length | Category |
| Under 10 years | Short-term |
| 10 to under 20 years | Moderate-term |
| 20+ years | Long-term |
Marriages under 3 years generally aren’t eligible for durational alimony, though bridge-the-gap or rehabilitative support may still apply if there’s a genuine short-term need.
Step 3: The 35% Formula
For durational alimony, Florida law sets a rebuttable presumption: the recipient’s reasonable need is capped at whichever is less — their actual documented need, or 35% of the difference between the spouses’ net monthly incomes.
What is a rebuttable presumption? It is a legal assumption that a fact is true unless it is proven otherwise by clear and convincing evidence.
Example: You take home $8,000/month net; your spouse takes home $3,000/month net. The difference is $5,000. Thirty-five percent of that is $1,750 — the presumed monthly ceiling. If your spouse’s actual documented need is only $1,200/month, the lower figure controls instead.
This is a starting point, not an automatic award. It can be challenged with evidence on either side, and judges are required to make written findings explaining exactly how they arrived at the number.
Step 4: The Other Factors That Shape the Number
The formula gives a ceiling — not the full picture. Under Florida Statute 61.08(2), judges also weigh:
- The standard of living established during the marriage
- Each spouse’s age, physical condition, and emotional health
- Each spouse’s financial resources, including marital and non-marital assets
- Contributions to the marriage, including homemaking and child-rearing
- The time needed for the requesting spouse to gain education or job skills
- All sources of income available to either spouse
Two Miami couples with identical incomes can walk away with very different alimony outcomes depending on how these factors apply to their marriage.
What If You Were Never Married?
Alimony only applies in a divorce. If you and your partner were never married, alimony does not apply. In addition, if you are in a relationship from which you have a child but were never married , the relevant legal issues are paternity, timesharing, and child support — not spousal support. Establishing paternity is its own process with its own deadlines, and it’s worth handling correctly from the start.
Flat-Fee Services
If you and your spouse already agree on alimony, property, and any child-related issues, you may qualify for my flat-fee uncontested divorce, — no hourly billing, typically finalized in under 30 days. To be clear, this means that I represent you, the spouse that contacts me, not both spouses—attorneys can only have one client. if you have an agreement with your spouse and you have questions, I can provide you unlimited legal advice throughout the process, and prepare all the necessary legal documents, including the agreement.
If your case involves a child born outside of marriage, ask about flat-fee paternity services to establish paternity, set a parenting plan, or get child support in place.
On the other hand, if you have questions about your legal rights about divorce, paternity and related family issues, schedule a $250 case assessment session and I will walk you through your rights and the process for your particular situation.

FAQ: Florida Alimony Calculations
Is there an official Florida alimony calculator?
No single government calculator exists. Some legal websites offer estimate tools based on the 35% formula and duration caps, but these only produce a rough ceiling — not a legally binding number. Your actual award depends on the full set of statutory factors applied to your case.
Does adultery affect alimony in Florida?
A court may consider adultery and any resulting economic impact when deciding alimony, but it is one factor among many — not an automatic penalty or bar to receiving support.
Is alimony taxable in Florida?
For divorce agreements executed after 2018, alimony is generally not tax-deductible for the payer and not taxable income for the recipient under federal law. Consult a tax professional for guidance specific to your situation.
What if my spouse and I agree on the alimony amount ourselves?
Courts generally respect a fair settlement agreement reached between spouses, provided it’s supported by full financial disclosure. Agreeing on alimony is often what allows couples to qualify for a flat-fee uncontested divorce instead of costly litigation.
