Florida Alimony / Spousal Support Calculator
Generic planning model for Florida alimony scenarios using entered gross incomes and marriage length. Does not apply Florida law or predict a court order.
Estimate only — these are not official figures
This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. The model does not determine legal eligibility, need, ability to pay, the legally relevant income measure, taxes, assets or debts, marital standard of living, earning capacity, health, misconduct, child-support or custody interactions, deviations, the actual payer or recipient, or a court-ordered amount or duration. The Florida approach classification and official citation are context, not encoded law.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Florida Statutes §61.08: https://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0000-0099/0061/Sections/0061.08.html; federal tax context: IRS Topic 452: https://www.irs.gov/taxtopics/tc452.

How This Calculator Works
Calculation methodology and assumptions
This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. The model does not determine legal eligibility, need, ability to pay, the legally relevant income measure, taxes, assets or debts, marital standard of living, earning capacity, health, misconduct, child-support or custody interactions, deviations, the actual payer or recipient, or a court-ordered amount or duration. Every result is therefore modeled or derived, not an official state-law calculation.
Key State Information
Florida is broadly classified as follows: the official framework relies on case-specific statutory or judicial factors rather than this site’s universal formula. This classification is legal context only and never changes the calculator’s math. Section 61.08 requires a factual finding of actual need and the other party’s ability to pay before its listed factors and statutory forms and duration limits are applied. Florida law does not use this calculator’s gross-income-difference formula.
Example Calculation
Here is how this site’s generic planning model works; it is not a Florida alimony calculation.
With entered annual gross incomes of $120,000 and $45,000, no minor children selected, and a 12-year marriage, the model uses 33% of the positive $75,000 difference: $24,750 per year, rounded to $2,063 per month. Its disclosed horizon is 12 × 8 = 96 months.
Result: Modeled result: $24,750 per year (about $2,063 per month) and a 96-month model horizon. The calculator has not tested legal eligibility, need, ability to pay, taxes, child support, assets, or any state factors, so this is not a court-award estimate.

Our editorial standardsFrequently Asked Questions
How is alimony calculated in Florida?
Florida Statutes §61.08 is the official starting point. Section 61.08 requires a factual finding of actual need and the other party’s ability to pay before its listed factors and statutory forms and duration limits are applied. Florida law does not use this calculator’s gross-income-difference formula. This planning tool does not implement the state guideline or factors. This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. None of its results determines a court award.
How long does alimony last in Florida?
This tool’s “duration” is only the disclosed model horizon, not a prediction of a court order. It cannot determine whether support is legally available or which statutory form, limit, exception, modification rule, or termination event applies. Check Florida Statutes §61.08 at https://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0000-0099/0061/Sections/0061.08.html.
Is alimony tax deductible in Florida?
This calculator does not calculate federal or state tax effects. IRS Topic 452 says payments under instruments executed after 2018 generally are not deductible by the payer or included by the recipient; pre-2019 instruments generally retain the former treatment unless a later modification expressly adopts the repeal. State treatment can differ. See https://www.irs.gov/taxtopics/tc452.
