Frequently Asked Questions — Auto Loan Calculator
How is a car loan payment calculated?
Car loan monthly payment uses the same formula as a mortgage: M = P × [r(1+r)^n] / [(1+r)^n − 1]. P is the loan amount (vehicle price + tax − down − trade-in), r is monthly interest rate, and n is the number of months. The result is a fixed payment that fully amortizes the loan.
Should I choose a shorter or longer loan term?
Shorter terms (36–48 months) have higher monthly payments but significantly lower total interest. Longer terms (72–84 months) lower monthly payments but you pay much more in interest and risk being "underwater" — owing more than the car is worth — as vehicles depreciate quickly.
What is a good interest rate for an auto loan?
As of 2024, average new car loan rates are around 6–8% APR for good credit (700+). Used car loans are typically 1–3% higher. Credit unions often offer lower rates than dealerships. Always compare financing offers before agreeing to dealer financing.
