Frequently Asked Questions
How much is a monthly car payment on a $35,000 car?+
With $5,000 down, $3,000 trade-in, 7% sales tax, 6.5% APR, and 60 months, the payment is about $620/month and total interest is roughly $3,600. Longer terms (72-84 months) lower the payment but add $1,000s in interest and can leave you upside down on the loan.
What is a good APR for a car loan in 2026?+
Excellent credit (720+) typically gets 4.5-6.5% on new cars in 2026. Good credit (690-719) 6.5-8%, and fair credit (630-689) 8-12%. Strong credit scores, shorter terms, and dealer incentives (0% offers) all lower your effective APR.
Should I include sales tax in my auto loan?+
Most dealerships finance the sales tax into the loan. Only a few states require paying tax upfront on trade-in credit. Financing the tax increases both your loan and your interest cost — paying it upfront saves money if you can afford it.
