What Is a Florida Alimony Calculator?

A Florida alimony calculator (also called a spousal support or durational alimony estimator) is an online tool that estimates how much monthly alimony one spouse may pay or receive after divorce in Florida. Unlike child support, which has a strict statewide guideline formula, alimony was historically left to wide judicial discretion. That changed dramatically on July 1, 2023, with Senate Bill 1416. Today’s calculators use the updated Florida Statute §61.08 to give you a realistic range based on:

• Length of marriage (from wedding date to filing date)
• Each spouse’s net monthly income (after taxes, per §61.30 guidelines)
• The lower-earning spouse’s reasonable monthly expenses (to maintain the marital standard of living)

These tools are estimates only — not guarantees. A judge makes the final call after reviewing all evidence. But a good calculator gives you clarity, bargaining power in mediation, and peace of mind before you hire an attorney.

Why use one in 2026?

• Permanent alimony is gone for all new cases.
• Maximum amounts and durations are now capped by law.
• You can run “what-if” scenarios in minutes instead of paying hundreds for an initial consultation.

Major Changes to Florida Alimony Laws

The 2023 reform (SB 1416) was the biggest overhaul in decades. Key updates that every Florida divorcing couple must know:

• Permanent (lifetime) alimony eliminated for divorces finalized after July 1, 2023.
• Only four types of alimony remain: temporary, bridge-the-gap, rehabilitative, and durational.
• Durational alimony is now the primary long-term option.
• Strict duration caps tied to marriage length.
• Strict amount cap: the lesser of (1) the recipient’s demonstrated need or (2) 35% of the difference between the spouses’ net incomes.
• Retirement, cohabitation, and adultery (if it has economic impact) can now more easily modify or terminate alimony.

These changes make Florida one of the more predictable states for spousal support nationwide.

The 4 Types of Alimony in Florida in 2026

1. Bridge-the-Gap Alimony – Short-term (max 2 years), non-modifiable, helps transition from married to single life.
2. Rehabilitative Alimony – Max 5 years, requires a specific plan (school, job training) to become self-supporting.
3. Durational Alimony – The most common long-term award; time-limited but can be substantial.
4. Temporary Alimony – Paid only while the divorce case is pending.

Our calculator focuses on durational alimony — the type most people mean when they search “Florida alimony calculator.”

How Florida Alimony Is Calculated

Florida Statute §61.08(8) provides a clear two-step process:

Step 1: Determine Maximum Duration Marriage length categories:

• Short-term (< 10 years): max 50% of marriage length
• Moderate-term (10–20 years): max 60% of marriage length
• Long-term (20+ years): max 75% of marriage length

Example: 12-year marriage = moderate-term → maximum 7.2 years of alimony.

Step 2: Determine Maximum Monthly Amount Amount = the lesser of:

• Recipient’s reasonable need (monthly expenses minus their net income), OR
• 35% of the difference between the higher-earner’s net income and the lower-earner’s net income.

Net income definition (important!): Use Florida child-support guideline net income (§61.30): gross pay minus federal & state taxes, FICA, mandatory union dues, and individual health insurance premiums. Do not use take-home pay after 401(k) or voluntary deductions.

Real-Life Example: 12-Year Marriage in Florida

Let’s use realistic numbers (same as our calculator demo):

• Marriage length: 12 years
• Higher earner net monthly income: $6,500
• Lower earner net monthly income: $2,800
• Lower earner reasonable monthly expenses: $4,500

Calculation:

1. Income difference = $6,500 – $2,800 = $3,700
2. 35% cap = $3,700 × 0.35 = $1,295
3. Demonstrated need = $4,500 – $2,800 = $1,700
4. Monthly alimony = lesser of $1,295 or $1,700 = $1,295 (capped at 35%)

Duration: Moderate-term marriage (12 years) → 60% × 12 = 7.2 years (7 years and 2–3 months).

Visual result: After alimony, the higher earner nets ~$5,205; lower earner nets ~$4,095 — both closer to maintaining the marital lifestyle.

This is exactly what our calculator outputs in seconds.

Additional Factors Florida Judges Must Consider (§61.08)

Even with the caps, judges still weigh these 12+ factors:

• Standard of living during marriage
• Age, physical/emotional condition of each spouse
• Financial resources and assets distributed in divorce
• Earning capacities and education levels
• Time needed for education or training
• Contributions to the marriage (including homemaking and child-rearing)
• Tax consequences
• Sources of income (including retirement accounts)
• Any adultery and its economic impact

A calculator gives you the statutory ceiling — the final award could be lower if other factors apply.

Common Mistakes People Make

• Using gross income instead of net
• Including voluntary 401(k) deductions
• Forgetting marriage length starts at filing date
• Expecting permanent alimony
• Not documenting reasonable expenses accurately
