Florida Alimony Calculator (2026)

Fla. Stat. § 61.08, amended by SB 1416 in 2023, reshaped Florida alimony: permanent support vanished for cases filed on or after July 1 2023, and durational alimony now follows a strict 35% income‑difference guideline and marriage‑length caps.

The law behind this calculator: Florida Statutes, Section 61.08 — durational alimony — Fla. Stat. § 61.08 (as amended by SB 1416, 2023).

How Florida calculates it

  • Calculate the net‑income difference: higher earner minus lower earner.
  • Take 35% of that difference – this is the guideline support amount.
  • Compare the guideline amount to the recipient’s reasonable need; the alimony awarded is the lesser of the two.
  • Determine the marriage‑length category (short, moderate, long) and apply the corresponding cap (up to 50%, 60% or 75% of the marriage length).
  • If the marriage lasted less than 3 years, no durational alimony may be awarded.

Worked example

In the example, the higher‑earning spouse earns $100,000 per year net and the lower‑earning spouse earns $40,000 per year net, creating a difference of $60,000. Thirty‑five percent of $60,000 equals $21,000 per year, or about $1,750 per month, subject to the recipient’s actual need. For an eight‑year marriage, which is classified as short‑term, the duration is capped at 50% of the marriage length, or roughly 48 months.

Frequently asked questions

Can I get durational alimony if my marriage lasted only 2 years?

No. Florida law bars durational alimony for marriages that lasted less than 3 years.

How does Florida calculate the amount of durational alimony?

The amount is the lesser of the recipient’s reasonable need or 35% of the difference between the spouses’ net incomes.

What is the maximum duration for alimony in a 15‑year marriage?

For a marriage of 10–20 years, Florida caps durational alimony at up to 60% of the marriage length.

Is permanent alimony still available for divorces filed after July 1 2023?

No. Permanent alimony was abolished for any case filed on or after July 1 2023 under the 2023 amendment.

Do I owe Florida state tax on alimony received under the new rules?

Florida has no state income tax, so alimony is not subject to state tax, though it may still be taxable at the federal level.

Is the calculation different in Jacksonville, Miami or Tampa?

No. Fla. Stat. § 61.08 (as amended by SB 1416, 2023) applies statewide, so courts in Jacksonville, Miami, Tampa and every other county start from the same guideline. Local practice can differ in how judges weigh deviation factors and in typical negotiated outcomes, but the formula on this page is the one used across Florida.
