We find error in the trial court holding that the interest rate on a judgment increased at various times in accordance with statutory increases enacted by the Legisla*442ture. Judgment was entered on the 19th day of September, 1979, and at that time interest accrued at the rate of 8% per an-num on judgments rendered in circuit court.1 The interest rate on judgments was increased to 10%, effective October 1, 1980.2 The interest rate on judgments was again increased to 12%, effective October 1, 1981.3
Generally the interest rate would change on an unsatisfied final judgment as the statute proscribing the rate of interest is amended, unless otherwise provided in the basic agreement upon which the final judgment was rendered. See Glades County, Fla. v. Kurtz, 101 F.2d 759 (5th Cir.1939); Anno. 41 ALR 4th 694, § 6 p. 703 and cases cited therein. However, in the instant case the several statutes which alter the interest rate specifically excluded the application of the new rate in a retroactive manner.4 Therefore, for reasons stated, the final order under review is reversed and remanded to the trial court for reconsideration and the entry of a total amount due based on interest accrued at the rate of 8% per an-num in accordance with Sec. 55.03(1), Florida Statutes (1991).
Reversed and remanded with directions.
