Frequently Asked Questions about the Auto Loan Calculator
What does this calculator include?
Vehicle price, down payment, trade-in value, sales tax, fees, term, and APR. It backs out the amount financed, the monthly payment, total interest paid, and the total out-of-pocket cost over the loan.
How is sales tax handled?
Most US states tax the vehicle price minus the trade-in value, not the full sticker price. This calculator follows that convention. A few states (CA, HI, VA) tax the full price; check your state if you need precision.
Can you give an example?
A $35,000 car with $5,000 down, no trade-in, 7% sales tax, $500 in fees, 60 months at 7% APR finances $32,600 and runs about $645 per month. Total interest paid is around $6,100.
Should I take a 72 or 84 month auto loan?
Longer terms cut the monthly payment but add interest and raise the risk of being underwater (owing more than the car is worth). Most lenders and consumer guides recommend 60 months or less for new cars.
What APR is reasonable in the US?
Rates depend on credit score and term. As of early 2026, prime borrowers see roughly 6-8% on new cars and 8-11% on used cars. Subprime borrowers can pay 15% or more. Always get quotes from a credit union too.
