Hi everyone, I financed a car in June of 2006. The original loan payment was about $336 a month for 72 months with an APR of about 9%. I financed something over $18,000. I figured I would send in an even $340 every month. Since then, my payment has continued to lower and lower, to the point where the last payment was only $280. My question is, why has it lowered? Also, if I pay only the lower amount, will the next payment go back to the original amount of $336? I would like to try sending them the $280 and then the extra $60 as a principal only payment, but I'm afraid then it will go back up and do more harm than good. Basically, I would like to have this loan paid off way before 72 months to avoid paying all that interest. What is my best option? Sorry for all the questions. Kinda new to loans and money and all this. Thanks!
