Answer:
For Loan A = 3.170%
For Loan B = 3.174%
Loan B has a higher effective annual rate.
Explanation:
The computation of effective annual rates for the loans is shown below:-
For Loan A
We will assume effective annual rate is a
Stated rate(r) = 3.125% compounded monthly
= Number of periods in an year n = 12
So,
(1 + a) = (1 + r ÷ n) × n
= a = (1+0.03125 ÷ 12) × 12 - 1
= 0.03170
or
= 3.170%
For Loan B
We will assume the effective annual rate is b
Stated rate (r) = 3.15% compounded semi annually
= Number of periods in an year n = 2
So
(1 + a) = (1 + r ÷ n) × n
= a = (1 + 0.0315 ÷ 2) × 2 - 1
= 0.03174
or
= 3.174%
From the above calculation we can see that Loan B, is greater than Loan A and has a higher effective annual rate.
