Frequently asked questions
What is the monthly payment on a $18,000 car loan?
At the average 8.5% rate, $18,000 runs about $444 a month over 48 months or $320 over 72 months.
Is a longer car loan term a good idea?
A longer term lowers the monthly payment but raises total interest and keeps you underwater on the car longer. Compare the all-in interest across terms, not just the monthly figure.
