<prompt> Human: Example: Car loan - 9635 balance remaining, 45 monthly payments 303month. I could refinance for 45 months 275 a month, saving me about 850 in interest. I could still pay the 303month, therefore paying an extra 28month to the loan balance.Or I could refinance for 51 months 245 a month, saving me about 450 in interest. I could still pay the 303month, therefore paying an extra 58month to the loan balance. Which way is more efficient to pay of the loan? Thanks in advance.  <response>: Stop looking at the payment. The better loan is the one with the lowest interest rate, and its best to pay that off in the shortest time that means paying over the minimum payment.Im not going to figure out the rates from your numbers, but the end goal should be minimum interest paid to the bank. Monthly payment does not tell you how much interest youre paying.
