As a potential borrower, which bank would you go to for a new loan?

First United Bank

 

Explanation:

For discrete compounding, to find the EAR, we use the equation:

EAR = [1 + (APR / m)]m − 1

So, for each bank, the EAR is:

First National: EAR = [1 + (.143 / 12)]12 − 1 = .1528, or 15.28%

First United: EAR = [1 + (.146 / 2)]2 − 1 = .1513, or 15.13%

Notice that the higher APR does not necessarily mean the higher EAR. The number of compounding periods within a year will also affect the EAR.
