This situation actually happened to me at Toyota of Garden Grove, although the numbers were changed for the benefit of simplicity: You are about to pay $10,000 cash for a new car. The finance manager, wanting to loan you money, asks you what interest rate you could earn on that money if you didn’t spend it. You answer 6%, compounded monthly. The finance manager then says that he will give you a loan at 7.5% interest, compounded monthly, with a five year term. He then shows you on his computer that if you invested the $10,000 on your own you would earn $3,488.50 in interest in five years. Then he shows you that your payments on the car would be $200.38 a month, making total interest paid on the car $2,022.7
