When you’re in the market for a new or used car, one of the biggest factors to consider is how you’ll finance your purchase. Auto loans are often the preferred method for many car buyers, allowing you to spread the cost over time. However, getting the best interest rate on your auto loan can save you thousands of dollars over the life of the loan. Understanding how to secure the best rates is crucial, and the process involves several key steps and factors. In this article, we’ll walk you through strategies to secure the lowest possible interest rates on your auto loan.
Key Takeaways
- Credit Score Matters: Your credit score plays a major role in determining the interest rate you will receive. Higher scores generally lead to better rates.
- Loan Term Affects Your Rate: Opt for a shorter loan term if possible, as it often comes with lower interest rates.
- Shop Around for the Best Rates: Don’t settle for the first offer; compare rates from various lenders, including banks, credit unions, and online lenders.
- Larger Down Payment Equals Lower Rates: A down payment of at least 20% can help you secure a better interest rate.
- Consider Refinancing: If interest rates drop or your credit score improves, refinancing your loan can save you money.
Understanding Auto Loan Interest Rates

Before diving into the specifics of getting the best interest rates, it’s important to understand how they work. The interest rate on an auto loan is essentially the cost of borrowing money, expressed as a percentage of the loan amount. The rate is added to your principal amount, and over time, you’ll pay both the principal and interest back to the lender.
There are two primary types of interest rates for auto loans:
- Fixed Rate: This rate remains the same for the duration of the loan, providing predictability in your monthly payments.
- Variable Rate: This rate can change over time, typically tied to a benchmark interest rate, such as the Federal Reserve’s rate. Your payments may fluctuate as the rate adjusts.
The interest rate you are offered will depend on several factors, which we will explore in the following sections.
Factors That Influence Your Auto Loan Interest Rate
Credit Score
One of the most significant factors determining your interest rate is your credit score. Lenders use your credit score to assess your creditworthiness, or how likely you are to repay the loan.
- Excellent Credit (750+): Those with excellent credit scores often qualify for the lowest interest rates.
- Good Credit (700-749): Borrowers with good credit may still qualify for competitive rates but might face slightly higher interest.
- Fair or Poor Credit (below 700): If your credit score is below 700, you may be offered higher interest rates, as lenders perceive you as a higher risk.
Loan Term
The length of your loan term can also impact your interest rate. Shorter loan terms (such as 36 or 48 months) typically come with lower interest rates because they are seen as less risky for the lender. However, the shorter the term, the higher your monthly payments will be. Longer loan terms (60 months or more) may have higher rates, but they offer lower monthly payments, making them attractive to some buyers.
Down Payment
Making a larger down payment can help you secure a lower interest rate. A substantial down payment reduces the amount you need to borrow, which makes the loan less risky for the lender. A down payment of at least 20% is often recommended for securing better terms.
Vehicle Type and Age
The type of vehicle you’re purchasing also plays a role in determining your interest rate. New cars typically come with lower interest rates because they are less likely to lose value quickly. Used cars, especially those that are several years old, may come with higher interest rates, as they are considered riskier investments for lenders.
Debt-to-Income Ratio
Your debt-to-income ratio (DTI) is another factor lenders consider. The DTI ratio compares your monthly debt payments to your monthly income. The lower your DTI ratio, the more favorable you’ll appear to lenders. Ideally, your DTI should be under 36% for the best loan rates.
Loan Amount
The size of your loan also impacts the interest rate. Larger loans typically come with higher interest rates, as they represent a greater risk for the lender. If you can lower the amount you need to borrow through a larger down payment or a less expensive car, you might be able to secure a better rate.
Lender Type
Different lenders offer different interest rates. Traditional banks, credit unions, online lenders, and dealership financing all have varying terms and rates. Credit unions often offer some of the best interest rates, but they may require membership. Online lenders and banks might offer competitive rates as well, but terms vary.
How To Get The Best Interest Rate On Your Auto Loan
Improve Your Credit Score
The higher your credit score, the better the interest rate you’re likely to receive. If your credit score is low, take some time to improve it before applying for an auto loan. Pay off outstanding debt, avoid missing payments, and keep your credit utilization low. Even a small increase in your score can make a significant difference in the interest rate you qualify for.
Shop Around
It’s essential to shop around and compare rates from multiple lenders before committing to a loan. Start by getting pre-approved for an auto loan, which will give you a clear idea of the interest rate you might qualify for. Don’t just settle for the first offer – compare rates from banks, credit unions, online lenders, and even dealership financing to ensure you’re getting the best deal.
Consider a Co-Signer
If your credit score is not great, consider asking a family member or friend with better credit to co-sign your loan. A co-signer provides the lender with additional security and may help you qualify for a lower interest rate. However, this is a big responsibility for the co-signer, so make sure to keep communication open and stay on top of payments.
Choose a Shorter Loan Term

While longer loan terms may seem appealing due to lower monthly payments, they typically come with higher interest rates. If you can afford higher monthly payments, opt for a shorter loan term. Not only will this help you pay off your loan faster, but you’ll also save money in interest.
Make a Larger Down Payment
A larger down payment reduces the total amount you need to borrow and shows the lender that you’re financially responsible. By putting down at least 20%, you may be able to lower your interest rate and avoid paying private mortgage insurance (PMI) in some cases.
Avoid Multiple Hard Inquiries
When shopping around for a loan, avoid having multiple lenders pull your credit report (also known as “hard inquiries”) in a short period of time. While comparing rates is important, having too many inquiries can hurt your credit score, potentially resulting in higher interest rates.
Consider Loan Pre-Approval
Getting pre-approved for an auto loan allows you to know exactly how much you can borrow and at what interest rate. It also puts you in a stronger negotiating position when you go to the dealership. Many lenders offer online pre-approval, making it quick and easy to compare your options.
