Question

You’ve worked out a line of credit arrangement that allows you to borrow up to $40 million at any time. The interest rate is .615 percent per month. In addition, 5 percent of the amount that you borrow must be deposited in a noninterest-bearing account. Assume that your bank uses compound interest on its line-of-credit loans.

What is the effective annual interest rate on this lending arrangement?

Explanation / Answer

Interest for a Month = 40,000,000 * 0.615%

Interest for a Month = 246,000

Amount for Use = 40,000,000 * (1 - 5%)

Amount for Use = 38,000,000

Interest rate Monthly = 246,000/ 38,000,000

Interest rate Monthly = 0.6473684%

Effectiva Rate = (1 + 0.6473684%)12 - 1

Effective Rate = 8.05%
