# Comment for Appendix J - Annual Percentage Rate Computations for Closed-End Credit Transactions

1. **Use of appendix J.** Appendix J sets forth the actuarial equations and instructions for calculating the annual percentage rate in closed-end credit transactions. While the formulas contained in this appendix may be directly applied to calculate the annual percentage rate for an individual transaction, they may also be utilized to program calculators and computers to perform the calculations.

2. **Relation to Bureau tables.** The Bureau's Annual Percentage Rate Tables also provide creditors with a calculation tool that applies the technical information in appendix J. An annual percentage rate computed in accordance with the instructions in the tables is deemed to comply with the regulation. Volume I of the tables may be used for credit transactions involving equal payment amounts and periods, as well as for transactions involving any of the following irregularities: odd first period, odd first payment and odd last payment. Volume II of the tables may be used for transactions that involve any type of irregularities. These tables may be obtained from the Bureau, 1700 G Street, NW, Washington, DC 20006, upon request.
