Payment Plan Math in Oregon

Oregon law sets the maximum interest rate for most written contracts at 9 percent per year, as specified in Or. Rev. Stat. § 82.010. This rate applies when parties have not agreed on a different rate in writing. The statute governs how interest accrues on unpaid balances under payment plans, including installment agreements and deferred payments. No additional charges may exceed this statutory ceiling unless another Oregon statute authorizes a higher rate for a specific type of transaction. The worked example below demonstrates how the 9 percent annual rate translates into periodic payments under a standard plan. For an estimate tailored to a particular agreement’s principal and term, the calculator uses the statutory rate and the official source’s framework to compute the result.
