There is a formula for calculating the TOTAL amount paid for a loan. (See attached).
r = monthly loan rate = 8.25 / 1,200 =
0.006875
p = principal = 27,000
n = number of payments = 11 years*12 months = 132
TOTAL Loan Cost =
0.006875
* 27,000 * 132 / 1 -(1.006875)^-132
TOTAL Loan Cost = 24,502.5 / (1 -
0.4047868312
)
TOTAL Loan Cost = 24,502.5 /
0.5952131688
TOTAL Loan Cost =
41,165.92
