Arizona Maximum Interest Rate on Payment Plans Under A.R.S. § 44-1201

Arizona law sets the maximum interest rate that may be charged on a payment plan at 10% per year under A.R.S. § 44-1201. This statute governs the legal rate of interest when a contract does not specify a different rate or when the parties agree to a payment arrangement. The 10% figure applies as the ceiling for any finance charge or interest on unpaid balances in such plans. The statute does not prescribe a single formula for calculating payments; instead, it sets the interest limit while the specific payment schedule and principal amount are left to the agreement. The worked example below illustrates how this rate applies in a typical calculation. To estimate your own payment plan figures, use the DocketMath calculator with your specific principal and term.
