Prejudgment interest in Florida compensates a winning party for losing the use of money between the date of loss and the judgment. Florida treats it as an element of pecuniary damages, not a penalty. It applies when the loss is a fixed sum on a fixed date, and the statutory rate usually governs.
What Prejudgment Interest Means in Florida Business Disputes
When a company wins a commercial case, the verdict often arrives years after the harm. Meanwhile, the money stayed with the other side. Prejudgment interest closes that gap. It is added to the damages award so that the winner is made whole for the delay.
Florida follows what courts call the loss theory. In Argonaut Insurance Co. v. May Plumbing Co., 474 So. 2d 212 (Fla. 1985), the Florida Supreme Court described prejudgment interest as “merely another element of pecuniary damages.” Once a verdict fixes damages as of a date certain, the court called the computation “merely a mathematical computation,” a ministerial duty rather than a discretionary choice.
This matters for planning. A plaintiff in a breach of contract, partnership or construction dispute should plead and prove the amount and the date of loss. Our business litigation practice sees this gap often, because teams focus on liability and treat interest as an afterthought.
When Florida Courts Award Prejudgment Interest
Florida courts look for two prerequisites. First, the plaintiff must show an out-of-pocket pecuniary loss. Second, the loss must be fixed as of a date, either by the evidence or by the verdict. The First District stated this two-part test in H&S Corp. v. U.S. Fidelity & Guaranty Co., 667 So. 2d 393 (Fla. 1st DCA 1995).
Contract claims
Contract claims fit the test most easily. A sum due on a stated date, such as an unpaid invoice, is a liquidated amount. Interest generally runs from the date payment was due. Courts allow interest on liquidated claims, meaning sums that are certain but that the defendant refuses to pay. See Air Ambulance Professionals, Inc. v. Thin Air, 809 So. 2d 28 (Fla. 4th DCA 2002).
For claims for breach of an agreement, the practical question is therefore whether the contract itself fixes a payment date. If it does, the argument for interest from that date is strong. If it does not, the plaintiff must show another date on which the loss became fixed.
Unjust enrichment and tort claims
Interest is also available outside contract when the pecuniary loss is clear from the outset. A federal court in the Southern District of Florida applied that rule to unjust enrichment and tort claims in TracFone Wireless, Inc. v. Hernandez, 196 F. Supp. 3d 1289 (S.D. Fla. 2016). Still, courts have refused interest where the damages were not a commercial obligation due on a date certain.
When the verdict fixes the date
Sometimes the evidence does not fix a date until the jury speaks. In that case, interest runs from the verdict to the final judgment. Likewise, once a verdict liquidates the plaintiff’s pecuniary loss, interest is due as a matter of law. See Capital Environmental Services, Inc. v. Earth Tech, Inc., 25 So. 3d 593 (Fla. 1st DCA 2009). Federal courts applying Florida law have said that “prejudgment interest can be awarded properly from the latest possible date of loss.” The Eleventh Circuit used that formulation in SEB S.A. v. Sunbeam Corp., 148 F. App’x 774 (11th Cir. 2005).
| Claim type | Typical date fixing the loss | Authority discussed above |
|---|---|---|
| Contract with a stated due date | The payment due date | Air Ambulance Professionals (Fla. 4th DCA 2002) |
| Unjust enrichment or tort with a clear pecuniary loss | The date the loss was clear | TracFone Wireless (S.D. Fla. 2016) |
| Loss fixed only by the jury | The verdict date or the date the verdict fixes | Capital Environmental (Fla. 1st DCA 2009) |
How Florida Sets the Prejudgment Interest Rate
For most disputes, the starting point is section 687.01. It provides that, where interest accrues without a special contract for the rate, the rate is the one provided in section 55.03 of the Florida Statutes. That section directs the Chief Financial Officer to set the statutory rate and to adjust it quarterly. In the statute’s own words, “the rate is the rate provided for in s. 55.03.”
The Department of Financial Services publishes the rates. For 2026, the department’s rate table lists these figures:
- 8.44% per year, effective January 1, 2026
- 8.25% per year, effective April 1, 2026
- 8.06% per year, effective July 1, 2026
- 7.87% per year, effective October 1, 2026
Because the rate changes each quarter, a long-running dispute can involve several rates. Therefore, parties should ask the court to state the rate and the periods on the face of the judgment. Section 55.03 also carries a savings clause: “Nothing contained herein shall affect a rate of interest established by written contract or obligation.” For scale, the department lists a daily rate of .000215616 for the quarter beginning October 1, 2026, so a $100,000 sum would accrue roughly $21.56 per day at that rate. In the first quarter of 2026, the listed daily rate of .000231233 produced roughly $23.12 per day on the same sum.
Contract Terms That Change the Interest Analysis
A well-drafted agreement can remove most of the uncertainty. A clause that states an interest rate on late payments typically controls over the statutory rate. A clause that fixes a payment date also supplies the date of loss. Conversely, a contract that is silent leaves both questions to the court.
Parties should review these terms before a dispute starts. Specifically, they should check the late-payment rate, the payment dates, any notice requirements and any fee-shifting language. A strategic settlement offer can also change the economics, as our guide to the Florida proposal for settlement rules explains.
From Prejudgment to Postjudgment Interest
Interest does not stop when the court enters judgment. Under section 55.03, a money judgment must state the rate on its face. The rate is fixed when the judgment is obtained, and it is then adjusted each January 1 to the rate in effect on that date until the judgment is paid.
Prejudgment interest also becomes part of the judgment. In Quality Engineered Installation, Inc. v. Higley South, Inc., 670 So. 2d 929 (Fla. 1996), the Florida Supreme Court held that prejudgment interest merges into the total sum adjudged, so it bears postjudgment interest like the other components.
Common Mistakes That Cost Interest
- Skipping the pleading. A complaint should ask for interest and identify the date from which it runs.
- Proving damages without a date. Evidence of the amount alone may not fix the date of loss.
- Ignoring the verdict form. If the jury does not fix a date, the accrual date can become a post-trial fight.
- Assuming one rate applies for the whole case. The statutory rate changes quarterly and judgments are adjusted each January.
- Overlooking the contract. A written rate or payment date may control the outcome.
Steps to Preserve a Prejudgment Interest Claim
- Read the contract for a late-payment rate, payment dates and notice terms.
- Plead interest in the complaint and identify the date it should run from.
- Prove the amount of the out-of-pocket loss and the date it was fixed.
- Ask for a verdict form line that fixes the loss date if the evidence is disputed.
- Ask the court to state the statutory rate on the face of the judgment.

Frequently Asked Questions
It is interest added to a damages award for the period between the date of loss and the judgment. Florida treats it as an element of pecuniary damages that makes the winner whole for the delay.
Where no contract sets a rate, section 687.01 points to the rate in section 55.03. The Chief Financial Officer adjusts that rate quarterly, and the 2026 rates range from 7.87% to 8.44%.
Yes. Section 55.03 states that it does not affect a rate of interest established by a written contract or obligation. Therefore, parties should read the late-payment clause first.
Generally, yes. The Florida Supreme Court held in Higley South that prejudgment interest merges into the judgment and bears postjudgment interest with the other components.
Conclusion
Prejudgment interest can add a meaningful sum to a Florida judgment, but it must be earned with a fixed loss and a fixed date. The statutory rate under section 55.03 supplies the default, and a written contract can displace it. Good records and a clear pleading make the difference.
