Mini Case: 27 – 33
p. The brothers need $100,000 and are considering a 1-year bank loan with a
quoted annual rate of 8%. The bank is offering the following alternatives: (1)
simple interest, (2) discount interest, (3) discount interest with a 10%
compensating balance, and (4) add-on interest on a 12-month installment loan.
What is the effective annual cost rate for each alternative? For the first three of
these assumptions, what is the effective rate if the loan is for 90 days, but
renewable? How large must the face value of the loan amount actually be in each
of the 4 alternatives to provide $100,000 in usable funds at the time the loan is
originated?
Answer: 1. With a simple interest loan, they gets the full use of the $100,000 for a year, and
then pay 0.08($100,000) = $8,000 in interest at the end of the term, along with the
and the effective annual rate is 8.24 percent:
EARsimple = (1.02)4 – 1 = 1.0824 – 1 = 0.0824 = 8.24%.
In general, the shorter the maturity (within a year), the higher the effective
cost of a simple loan.
the effective annual rate is 8.7 percent:
