How this auto loan calculator works
Enter the vehicle price, your down payment (or trade-in value), the interest rate, and the loan term to estimate your monthly payment and total interest — using the same fixed-rate amortization math a dealership finance office uses. It doesn't include sales tax, title/registration fees, or add-ons some dealers roll into the loan, so your actual financed amount may be a bit higher.
Shorter terms mean a higher monthly payment but far less total interest — try adjusting the term to see the trade-off. New car loans typically carry lower rates than used car loans; if you already have a quote, plug in that exact rate for the most accurate estimate.
