Accuracy of annual percentage rate.
Accuracy of annual percentage rate.
(1) The annual percentage rate is a measure of the cost of credit, expressed as a yearly rate, that relates the amount and timing of value received by the consumer to the amount and timing of payments made. The annual percentage rate shall be determined in accordance with either the actuarial method or the United States Rule method. Explanations, equations and instructions for determining the annual percentage rate in accordance with the actuarial method are set forth in appendix J to this part. An error in disclosure of the annual percentage rate or finance charge shall not, in itself, be considered a violation of this part if:
(i) The error resulted from a corresponding error in a calculation tool used in good faith by the creditor; and
(ii) Upon discovery of the error, the creditor promptly discontinues use of that calculation tool for disclosure purposes and notifies the Bureau in writing of the error in the calculation tool.
(2) As a general rule, the annual percentage rate shall be considered accurate if it is not more than 1/8 of 1 percentage point above or below the annual percentage rate determined in accordance with paragraph (a)(1) of this section.
(3) In an irregular transaction, the annual percentage rate shall be considered accurate if it is not more than 1/4 of 1 percentage point above or below the annual percentage rate determined in accordance with paragraph (a)(1) of this section. For purposes of this paragraph (a)(3), an irregular transaction is one that includes one or more of the following features: multiple advances, irregular payment periods, or irregular payment amounts (other than an irregular first period or an irregular first or final payment).
(4) Mortgage loans. If the annual percentage rate disclosed in a transaction secured by real property or a dwelling varies from the actual rate determined in accordance with paragraph (a)(1) of this section, in addition to the tolerances applicable under paragraphs (a)(2) and (3) of this section, the disclosed annual percentage rate shall also be considered accurate if:
(i) The rate results from the disclosed finance charge; and
(ii)
(A) The disclosed finance charge would be considered accurate under § 1026.18(d)(1) or § 1026.38(o)(2), as applicable; or
(B) For purposes of rescission, if the disclosed finance charge would be considered accurate under § 1026.23(g) or (h), whichever applies.
(5) Additional tolerance for mortgage loans. In a transaction secured by real property or a dwelling, in addition to the tolerances applicable under paragraphs (a)(2) and (3) of this section, if the disclosed finance charge is calculated incorrectly but is considered accurate under § 1026.18(d)(1) or § 1026.38(o)(2), as applicable, or § 1026.23(g) or (h), the disclosed annual percentage rate shall be considered accurate:
(i) If the disclosed finance charge is understated, and the disclosed annual percentage rate is also understated but it is closer to the actual annual percentage rate than the rate that would be considered accurate under paragraph (a)(4) of this section;
(ii) If the disclosed finance charge is overstated, and the disclosed annual percentage rate is also overstated but it is closer to the actual annual percentage rate than the rate that would be considered accurate under paragraph (a)(4) of this section.
