Periodic interest rates. You have a savings account in which you leave the funds for one year without adding to or withdrawing from the account. Which would you rather have: a daily compounded rate of 0.055%, a weekly compounded rate of 0.355%, a monthly compounded rate of 1.45%, a quarterly compounded rater of 4.50%, a semiannually compounded rate of 7%, or an annually compounded rate of 15%?
What is the effective annual rate (EAR) of a daily compounded rate of 0.055%?
_________% (Round to two decimal places.)

Which periodic rate would you rather have for your savings account? (Select the best response.)
A. Upper A quarterly compounded rate of 4.50%.
B. Upper A monthly compounded rate of 1.45%.
C. An annually compounded rate of 15%.
D. Upper A daily compounded rate of 0.055%.
E. Upper A weekly compounded rate of 0.355%.
F. Upper A semiannually compounded rate of 7%.
Daily: Periodic Rate = 0.055 %, Number of Periods in a Year = 365
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.00055]^(365) - 1 = 0.2222 or 22.22 %
Weekly:
Periodic Rate = 0.355 %, Number of Periods in a Year = 52
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.00355]^(52) - 1 = 0.2023 or 20.23 %
Monthly:
Periodic Rate = 1.45 %, Number of Periods in a Year = 12
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.0145]^(12) - 1 = 0.1886 or 18.86 %
Quarterly:
Periodic Rate = 4.5 %, Number of Periods in a Year = 4
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.045]^(4) - 1 = 0.1925 or 19.25 %
Semi-Annual:
Periodic Rate = 7 %, Number of Periods in a Year = 2
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.07]^(2) - 1 = 0.0.1449 or 14.49 %
Annual:
Periodic Rate = 15 %, Number of Periods in a Year = 1
Effective Annual Rate = [1+Periodic Rate]^(Number of Periods in a Year) - 1 = [1.15]^(1) - 1 = 0.15 or 15 %
As the Effective Annual Rate is highest for daily compounding, the same should be chosen.
