Is it worth it to refinance my auto loan? see details....?

My current auto loan is at 9.1 % interest and was for 60 months. It has been one year and all my payments have been on time and I have good credit. I would have the opportunity to refinance at 7.99% for the remaining 48 months. Would this be worth the hassle? How much would I even save?

Your total savings depends on how much your car cost.

I assumed $15,000, and found that you would pay $2463.53 in interest if you keep the old loan, and pay $2148.33 in interest if you take the new loan.

That's saving you around $315, assuming the $15,000 car. That also assumes that there are no refinancing charges or fees.

Tell me how much the car is worth and I will provide you with a more accurate cost savings.

I'd say if the hassle was low go for it...
hi
depending on you finance. and how long you have been paying on the 9.1%
If you refinace you will start at the top by paying the interest first.

you can check at kelly blue book for more info
Unless we know how much you financed in the first place and what your principal balance currently is, there is no way to figure out how much you would save.

However, assuming that your current balance is $15,000 (I picked the number out of the sky), you would save approximately $340 over the next 5 years in interest. If your current balance is higher or lower then that, the number would be different.
There are some points of concern you have left out. Do you have enough equity in the car. Most people with 60 month loans are "upside down" in the loan (they owe more than the car is worth) to avoid this 15% down is the minimum. Many financial institutions will only finance a percentage of the blue book value (80 to 90 percent) That's a very good rate, are you sure it's for a used car (used is a higher rate than new) and is it for a 48 month loan, a lot of "teaser" rates are for 18 or 24 months. Be very careful about the terms, there are many "sub prime" loans available with unique terms that favor the lender.
The above answers are generally correct. Given the relatively small savings offered by refinancing, why not consider paying something extra each month to reduce the balance, the length of the loan and, consequently, the amount of interest paid. Even an extra $50/month might result in significant savings.
