10 Car Loan Mistakes That Cost You Thousands

1. Not Checking Your Credit Score First

Your credit score plays a significant role in the interest rate you're offered and the terms you qualify for. Without knowing your score, you might accept a loan with a higher interest rate than necessary, costing you hundreds or thousands of dollars over the life of the loan.

Before visiting a dealership or applying for a loan, obtain your credit score from a reputable source. Regularly reviewing your credit report for errors can also help you improve your score and negotiate better loan terms.

2. Skipping Pre-Approval

Pre-approval from a lender gives you a clear picture of how much you can borrow and the interest rate you qualify for. Without it, you may be at the mercy of dealership financing, which often includes higher rates and less favorable terms.

Getting pre-approved from a credit union, bank, or online lender before shopping allows you to compare offers and negotiate from a position of strength. It also helps you focus on cars within your budget.

3. Focusing Only on Monthly Payment

Many car shoppers focus solely on the monthly payment, but this can lead to overpaying in the long run. Dealers may extend the loan term to lower the monthly payment, which increases the total interest you pay.

Instead, consider the total cost of the loan—including the interest and fees—and ensure the car itself is within your budget. The Consumer Financial Protection Bureau (CFPB) advises comparing offers based on the APR, loan term, and total cost, not just the monthly payment.

For example, a $20,000 loan at 4.75% interest with a 36-month term results in $1,498 total interest, while the same loan over 72 months results in $3,024 total interest—more than twice as much.

4. Ignoring Loan Term Total Cost

The loan term directly affects how much interest you pay. A longer term lowers your monthly payment but increases the total interest paid, and it also increases the risk of owing more than the car is worth.

Financial experts, including the CFPB, recommend keeping your auto loan to five years or less. Before signing, calculate or ask for the total cost of the loan and the interest rate, and decide whether the longer term is truly worth the lower monthly payment.

Be especially cautious with terms of 72 months or longer, as they often lead to being 'upside down' on the loan, where you owe more than the vehicle's value.

5. Not Negotiating the Interest Rate

Many borrowers accept the first interest rate offered, but you can negotiate. The CFPB states that you can negotiate the interest rate and length of the loan, as well as additional fees and optional add-ons.

Before negotiating, know your credit score and compare rates from multiple lenders. If a dealership offers a higher rate, you can use your pre-approval as leverage or simply walk away if they won't match it.

6. Neglecting Fees and Add-Ons

Car loans often come with additional fees and add-ons that can inflate the total cost. These may include financing charges, documentation fees, extended warranties, and GAP insurance. The monthly payment includes the principal, interest, and any optional add-ons you choose.

Be wary of add-ons you don't need or can purchase elsewhere at a lower price. Ask the dealer for a detailed breakdown of all fees and negotiate or decline unnecessary ones. Always review the contract to ensure the APR, amount financed, finance charge, and total payments match what you agreed to.

7. Taking a Loan for Too Long

An extended loan term of 72 months or more may lower your monthly payment, but it also increases the total interest paid and the risk of being 'upside down' on the loan. The CFPB warns that longer loans are more likely to result in owing more than the vehicle is worth.

If you can afford the higher monthly payment, a shorter loan term—such as 36 or 48 months—is usually a wiser financial choice. As a rule, aim to pay off your car loan within five years or less.

8. Not Reading the Contract

Before signing any car loan contract, carefully read every detail. The CFPB advises ensuring that the APR, amount financed, finance charge, and total of all payments match what was agreed upon. Make sure you receive signed copies of all documents.

If you spot any discrepancies or unexpected fees, address them before signing. If the dealer pressures you to sign without time to review, consider that a red flag and take the contract home to read it thoroughly.

9. Skipping Gap Insurance

Gap insurance covers the difference between your car's value and the amount you owe if the car is totaled or stolen. While it's an optional add-on, it can be a financial lifesaver if you have a long-term loan or put down a small down payment, as these situations increase the risk of owing more than the car is worth.

Check whether your existing auto insurance policy includes gap coverage, and compare prices with what the dealer offers. If you're buying gap insurance, make sure it's clearly listed in the contract and understand its terms.

10. Not Refinancing When Rates Drop

Interest rates can change over time, and refinancing your auto loan when rates drop can save you money. However, refinancing also involves fees and may extend your loan term, so weigh the costs and benefits.

If your credit score has improved since you took out the loan, you might qualify for a better rate. Compare offers from lenders and consider the total cost of refinancing before deciding. Always check the terms of your current loan for any prepayment penalties.
