A loan of $12,000 is to be repaid within one year with level
monthly payments, due at the beginning of each month. The 12
payments equal $1,000 each. A finance charge of $632 is also due
with the first payment. Which of the following is closest to the
effective annual interest rate on the loan?
(A) 12.7% (B) 12.9% (C) 13.1% (D) 13.3% (E) 13.5%
I'd appreciate it if you could let me know...
At the Interest rate - |
Outflow = Inflow |
Present Value of Payments = Loan Amount |
1000+632 + [1000 x ( PVAF(r%,11))] = 12000 |
1000 x PVAF(r%,11) = 12000-1632 |
PVAF(r%,11) = 10368/1000 |
PVAF(r%,11) = 10.368 |
Using Annuity Table - |
PVAF(1%,11) = 10.9676 |
This is approximately equal to 10.368 |
Therefore r = 1% per month Compounded Monthly |
Annual interest rate = [(1+0.01)^12]-1 |
r =[1.01^12 ] -1 |
r = 12.68% |
or |
12.70% |
