Frequently Asked Questions

What is the monthly payment on a $18,000 car loan?
At a typical 7% APR over a 60-month term, the monthly payment on a $18,000 car loan is about $356.42. Your exact payment depends on your credit score, the lender, and whether the car is new or used.
What's a good auto loan interest rate?
As of 2025, a good APR for buyers with excellent credit (750+) is typically 5%–7% for new vehicles and 7%–10% for used vehicles. The average across all credit tiers is closer to 7%–11% for new cars and 11%–14% for used cars.
Do new and used cars have different loan rates?
Yes. Used car loans typically carry higher APRs than new car loans — often 2–4 percentage points higher — because lenders see older vehicles as higher risk collateral.
Does a longer loan term cost more overall?
Yes. A longer term (60–84 months) lowers your monthly payment but increases total interest paid and raises the risk of owing more than the car is worth. Financial experts generally recommend terms of 60 months or less.
