Determination of annual percentage rate

The annual percentage rate applicable to any extension of consumer credit shall be determined, in accordance with the regulations of the Bureau, in the case of any extension of credit other than under an open end credit plan, as Where a creditor imposes the same finance charge for balances within a specified range, the annual percentage rate shall be computed on the median balance within the range, except that if the Bureau determines that a rate so computed would not be meaningful, or would be materially misleading, the annual percentage rate shall be computed on such other basis as the Bureau may be regulation require. The disclosure of an annual percentage rate is accurate for the purpose of this subchapter if the rate disclosed is within a tolerance not greater than one-eighth of 1 per centum more or less than the actual rate or rounded to the nearest one-fourth of 1 per centum. The Bureau may allow a greater tolerance to simplify compliance where irregular payments are involved. The Bureau may authorize the use of rate tables or charts which may provide for the disclosure of annual percentage rates which vary from the rate determined in accordance with subsection (a)(1)(A) by not more than such tolerances as the Bureau may allow. The Bureau may not allow a tolerance greater than 8 per centum of that rate except to simplify compliance where irregular payments are involved. In the case of creditors determining the annual percentage rate in a manner other than as described in subsection (d), the Bureau may authorize other reasonable tolerances.
