Interest in Oregon

Under Oregon’s prejudgment interest statute, the rate is set at 9% per year. Or. Rev. Stat. § 82.010 establishes this fixed annual rate for interest on judgments, decrees, and other obligations when the parties have not agreed to a different rate in a contract. The statute applies from the date the amount becomes due until the date of judgment. The law does not provide a sliding scale or variable rate; the 9% figure is the single statutory rate specified in the code. The example below shows how the 9% annual rate is applied over a given period. For a precise estimate based on the specific principal amount and time frame in a case, use the DocketMath calculator. The full statutory text is available at the Oregon Legislature’s official site.
