The rate itself, and the date interest starts running, which differs by claim type in most states.
Statutory interest rate
8.06% / year (effective Jul 1, 2026 through Sep 30, 2026)
The Chief Financial Officer sets the rate quarterly, with new rates taking effect Jan 1, Apr 1, Jul 1 and Oct 1 each year (the CFO publishes each new rate roughly a month ahead, around Dec 1, Mar 1, Jun 1 and Sep 1). Has ranged roughly 8%-9.5% over the past two years, trending downward from a 9.50% peak in late 2024.

Confirmed against the Florida CFO judgment interest rate page and corroborated by a Florida Bar News notice; current published rate is 8.06% for the quarter beginning Jul 1, 2026, unchanged from the prior research pass. Correction from prior entry: the CFO's quarterly rates take effect on calendar-quarter starts (Jan 1, Apr 1, Jul 1, Oct 1), not Dec 1/Mar 1/Jun 1/Sep 1 as previously noted; those dates are closer to when the CFO announces the upcoming rate. No Oct 1, 2026 rate has been published yet as of this check. Compounding was not independently confirmed against primary statutory text this pass.
Accrual: breach of contract claim
Measured as of the breach date, but courts have equitable discretion to pick a different trigger date
Repair/replacement damages are typically measured as of the breach date, but Florida courts (e.g., Broward County v. Finlayson) recognize an equitable exception letting the court choose a different date, such as substantial completion, when that produces a fairer result.

The link goes to Argonaut, the seminal case both rely on and the one with a free full-text copy available. A free, directly-linkable full-text copy of Finlayson itself wasn't found this pass; the exact accrual date can genuinely move based on case facts and this is one of the more court-discretion-dependent entries in this batch.
Accrual: property damage / tort claim
From date of loss ('loss theory'), once a verdict liquidates the damages amount
Under Florida's 'loss theory,' once a verdict fixes damages as of a prior date, prejudgment interest follows from that date as a matter of law, not judicial discretion. The Florida Supreme Court reasoned the loss itself is a wrongful deprivation of the plaintiff's property from that date forward.

This case-law rule applies to property damage/tort claims; personal-injury awards are excluded per the same opinion.
