Stated Rate (APR) Number of Times Compounded Effective Rate (EAR)
8.2 % Quarterly %
17.2 Monthly
13.2 Daily
10.2 Infinite

Answer 1

a. 8.46%

b. 18.62%

c. 14.11 %

d. 10.74%

Step-by-step explanation:

Effective annual rate = (1 + periodic interest rate)^m - 1

Periodic interest rate = APR / number of compounding

m = number of compounding

a. (1 + 0.082 / 4 ) ^4 - 1 = 8.46%

b. (1 + 0.172 / 12) ^12 - 1 = 18.62%

c. (1 + 0.132 / 365) ^365 - 1 = 14.11 %

d. EAR = е^0.102 - 1 = 10.74%
