Stretching the term to fit the budget
Long terms can increase total interest and keep you upside down on the vehicle for longer.
Determine your car loan monthly payment based on vehicle price, interest rate, and loan length.
Auto loan payments are determined by the vehicle price (minus any down payment or trade-in), the interest rate, and the loan term. Unlike mortgages, auto loans are typically shorter — ranging from 24 to 84 months — because vehicles depreciate in value over time.
Interest rates for auto loans vary widely based on credit score, whether the car is new or used, and the lender. New car loans typically carry lower rates than used car loans. Dealership financing may be convenient, but credit unions and banks often offer more competitive rates, so it pays to shop around.
While longer loan terms (72 or 84 months) lower your monthly payment, they come with risks. You may end up "upside down" on the loan — owing more than the car is worth — for a longer period. Financial experts generally recommend keeping auto loans at 60 months or less to minimize total interest and avoid negative equity.
The total cost of the vehicle minus your down payment and trade-in value. A larger down payment reduces both the loan amount and total interest paid.
Auto loan rates depend on your credit score, loan term, and whether the vehicle is new or used. Rates can range from under 3% to over 15%.
Common auto loan terms are 36, 48, 60, and 72 months. Shorter terms mean higher monthly payments but lower total interest costs.
New cars typically qualify for lower interest rates but depreciate faster. Used cars may have higher rates but cost less overall.
A good auto loan rate depends on your credit profile and market conditions. Borrowers with excellent credit (750+) can often secure rates between 3% and 5% for new cars. Used car rates are typically 1-2% higher. Rates above 10% are considered high and may indicate it is worth improving your credit before purchasing.
