How Bad Credit Affects Your Car Loan Rate
When you have bad credit, lenders see you as higher risk, so they charge you a higher interest rate to compensate. The difference is substantial: someone with excellent credit might get a car loan at 4 percent, while someone with a credit score below 580 might see rates between 18 and 29 percent, depending on the lender and the loan term. Your actual rate depends on your credit score, the age of negative marks on your report, how much you're putting down, and which lender you approach.
The credit score ranges that matter most are: 300–579 (very poor), 580–669 (fair), 670–739 (good), and 740 and above (excellent). Most traditional banks won't lend below 620. Credit unions and subprime lenders — companies that specialize in bad credit loans — will work with lower scores, but their rates reflect that risk. A rate that seems high is not a scam; it's how these lenders price the loan to account for the chance you might not repay it.
Key Takeaways
- Bad credit car loans typically carry interest rates between 12 and 29 percent, compared to 4 to 8 percent for borrowers with good credit.
- Your exact rate depends on your credit score, down payment size, loan term, and which type of lender you use — credit unions, banks, or subprime specialists.
- A larger down payment reduces the lender's risk and often lowers your interest rate by one to three percentage points.
- Comparing offers from multiple lenders before you buy can save you thousands in interest over the life of the loan.
- Negative marks older than two years have less impact on your rate than recent ones, so timing matters when you shop.
Where Your Credit Score Sits and What That Means for Rate
Your credit score is a three-digit number that summarizes your payment history, amounts owed, length of credit history, credit mix, and recent inquiries. The most common scoring model is FICO, which ranges from 300 to 850. Most car lenders use FICO scores, though some use alternative scores like Vantage Score.
If your score is between 580 and 619, you're in the subprime range. Traditional banks will decline you, but credit unions and subprime lenders will work with you. Expect rates in the 18 to 29 percent range. If your score is between 620 and 659, you're borderline; some banks will lend, but at higher rates (usually 12 to 18 percent). Above 660, you move into the prime market, where rates drop to 8 to 12 percent. The jump from 619 to 620 can mean a 3 to 5 percentage point difference in your rate.
Recent negative marks hurt more than old ones. A bankruptcy from seven years ago affects your rate less than a missed payment from three months ago. If you have the option to wait six months to a year before buying, your score will likely improve enough to lower your rate by 2 to 4 percentage points.
How Down Payment Size Changes Your Rate
The more money you put down, the less the lender has to risk. A 20 percent down payment typically lowers your rate by 1 to 3 percentage points compared to a 0 percent down deal. If you're looking at a $15,000 car and can put $3,000 down instead of nothing, you might move from 22 percent to 19 percent — a real difference over a five-year loan.
Down payment also affects how long you'll be underwater on the loan (owing more than the car is worth). With bad credit, you're already paying more in interest, so a larger down payment protects you if the car needs major repairs early or loses value faster than expected. Lenders know this too, which is why they reward it with lower rates.
If you don't have cash for a down payment, some lenders will accept a trade-in. The value of your trade-in counts as your down payment. If you have no trade-in and no cash, you'll pay the highest rate the lender offers, but you can still get approved.
Comparing Rates From Banks, Credit Unions, and Subprime Lenders
You have three main sources for a bad credit car loan: traditional banks, credit unions, and subprime lenders. Each prices risk differently, so your rate will vary by lender even if your credit score is the same.
Traditional banks (Wells Fargo, Chase, Bank of America) usually require a credit score of 620 or higher. If you may have access to, their rates are lower than subprime lenders — typically 10 to 16 percent for bad credit borrowers. The downside: approval takes longer, and they may require a co-signer.
Credit unions are nonprofit organizations owned by their members. They often offer rates 2 to 4 percentage points lower than banks for the same credit profile, and they're more flexible about credit score minimums. You must be a member to borrow, but membership is often free or costs $5 to $25. If you work for a large employer, are part of a professional association, or live in a certain area, you likely may have access to for a credit union. Start by searching your employer's name plus "credit union" or visiting CO-OP Network to find one near you.
Subprime lenders (Santander, Westlake Financial, DriveTime) specialize in borrowers with scores below 620. They approve faster — sometimes same-day — but charge the highest rates, typically 15 to 29 percent. They also often require you to buy the car from their dealership, which limits your choice of vehicle. Use subprime lenders only if banks and credit unions have declined you.
What Happens When You Shop Around
Getting rate quotes from multiple lenders is free and does not lock you into anything. When you request a quote, the lender performs a hard inquiry on your credit report, which temporarily lowers your score by a few points. However, multiple inquiries for the same type of loan (car loans) within 14 to 45 days count as a single inquiry, depending on the scoring model. This means you can shop around without major damage to your score.
Collect quotes from at least three lenders: one traditional bank, one credit union, and one subprime lender if you're below 620. Write down the interest rate, loan term (36, 48, 60, or 72 months), and any fees. A lower rate on a longer term might cost you more in total interest than a higher rate on a shorter term, so compare the total amount you'll pay, not just the rate.
Once you've chosen a lender, that quote is usually good for 30 to 60 days. You can then shop for a car knowing your budget and your rate. Do not let a car dealer shop for financing on your behalf if you've already been approved elsewhere; dealer financing often carries higher rates and additional fees.
The Real Cost of a High Interest Rate Over Time
A high interest rate compounds over the life of the loan. On a $15,000 car financed over 60 months, the difference between 10 percent and 20 percent is roughly $4,000 in extra interest. Over 72 months, that gap widens to $5,500. These numbers are why down payment and loan term matter: a larger down payment reduces the principal, and a shorter term means less time for interest to accumulate.
Some borrowers with bad credit are tempted to take a 72-month or 84-month loan to lower the monthly payment. This is usually a mistake. You'll pay far more in interest, and you'll be at higher risk of owing more than the car is worth if it needs major repairs. A 60-month loan is a better balance for bad credit borrowers: the payment is manageable, and you're not buried in interest.
If your rate is above 18 percent, consider waiting six months to a year to improve your credit score before buying. A score improvement of 40 to 60 points can lower your rate by 3 to 5 percentage points, which saves thousands over the life of the loan.
Frequently Asked Questions
Can I get a better rate if I have a co-signer?
Yes. A co-signer with good credit can lower your rate by 2 to 5 percentage points because the lender can pursue them if you don't pay. The co-signer's credit score and income are considered alongside yours. Be aware that the loan appears on both your credit reports, so missed payments hurt both of you.
What if I'm denied by a bank or credit union?
A denial usually means your credit score is below their minimum or you have recent serious delinquencies (missed payments, collections, bankruptcy). You can still borrow from a subprime lender, but expect rates in the 18 to 29 percent range. Ask the lender that denied you what specific factors led to the denial; sometimes it's fixable (like a recent error on your report) and worth addressing before you explore elsewhere.
Does the type of car I buy affect my interest rate?
Yes, slightly. Lenders prefer newer cars and popular models because they're easier to repossess and resell if you default. A 2022 Honda Civic will get you a lower rate than a 2015 Kia with 120,000 miles, all else equal. However, the difference is usually 1 to 2 percentage points, so don't overspend on a newer car just to save on interest.
What if my rate is locked in but my credit improves before closing?
Most lenders will not re-quote you after a rate lock. However, if your credit score improves significantly (50+ points) between the quote and closing, it's worth asking. Some lenders will re-pull your credit and adjust the rate if the improvement is substantial. There's no harm in asking, and you have nothing to lose.
Can I refinance my car loan later if my credit improves?
Yes. After 12 to 24 months of on-time payments, your credit score will improve, and you can refinance to a lower rate with a different lender. A refinance replaces your original loan with a new one at a better rate. You'll pay closing costs (typically $200 to $500), but if your rate drops by 3 or more percentage points, the savings usually justify the cost. Refinancing also resets your loan term, so be careful not to extend it beyond your original payoff date.
