Payment Plan Math in Pennsylvania

Pennsylvania’s payment plan math is governed by 73 P.S. § 1001, which caps the interest rate a seller may charge on an installment sale at 6% per year. This statute applies to retail installment contracts and sets the maximum lawful rate for time-price differentials. The rule does not prescribe a single formula for calculating total payments; instead, it establishes the upper limit for interest, leaving the specific amortization method to the contract terms. The official source, linked below, contains the exact statutory text. The worked example on this page demonstrates how the 6% ceiling applies in a typical calculation. For an estimate tailored to a particular agreement, use DocketMath’s payment plan calculator.
