Example
**Example: Buying a $35,000 Car** Vehicle Price: $35,000 | Down Payment: $5,000 | Trade-In: $3,000 Sales Tax: 7% | Interest Rate: 6.5% APR | Term: 60 months **Step 1:** Sales Tax = ($35,000 − $3,000) × 7% = $2,240 **Step 2:** Loan Amount = $35,000 + $2,240 − $5,000 − $3,000 = $29,240 **Step 3:** Monthly Payment = $29,240 × [0.00541(1.00541)⁶⁰] ÷ [(1.00541)⁶⁰ − 1] = **$572.36/mo** **Step 4:** Total Cost = $572.36 × 60 = $34,342 | Total Interest = $34,342 − $29,240 = $5,102 **Key Insight:** A lower interest rate or shorter term can save thousands in interest.

Frequently Asked Questions

What factors affect my monthly car payment?

Your monthly payment is primarily determined by the loan amount (vehicle price minus down payment and trade-in, plus sales tax), interest rate, and loan term. A higher down payment, lower APR, or shorter term all reduce your monthly payment.

Should I choose a shorter or longer loan term?

Shorter terms (36-48 months) have higher monthly payments but much lower total interest. Longer terms (72-84 months) have lower monthly payments but cost significantly more in interest over the life of the loan. We recommend the shortest term you can comfortably afford.

How does a down payment affect my auto loan?

A larger down payment reduces the loan amount, which lowers your monthly payment and total interest. A down payment of at least 20% is recommended to avoid being upside-down (owing more than the car is worth) in the first years of ownership.

What is a good APR for a car loan?

APR rates vary based on credit score, loan term, and market conditions. As of 2026, well-qualified buyers (720+ credit) might see rates of 4-7% for new cars and 6-10% for used cars. Improving your credit score before applying can save thousands over the life of the loan.
