Suppose that you borrow $17,000 for five years at 6% toward the purchase of a car. Find the monthly payments and the total interest for the loan.
PMT=PV . R .{[1 +R]^N / [1 + R]^N - 1}
PMT= 17,000 x 0.005 x {[1 + 0.06/12]^(6*12) / [1 + 0.06/12]^(6*12) - 1]}
PMT= 85.00 x 3.3145776.....
PMT=$281.74
$281.74 x 72 =$20,285.28 Total principal + interest.
$20,285.28 - $17,000 =$3,285.28 Total interest on the loan.
