What your credit score does to your car loan
Your credit score is the single number that determines whether a lender will give you a car loan, how much you can borrow, and what interest rate you'll pay. A higher score gets you lower rates; a lower score either locks you out of borrowing or costs you thousands of dollars in extra interest over the life of the loan.
Lenders use your credit score as a shorthand for risk. They're asking: has this person paid back borrowed money on time in the past? If yes, they'll lend to you cheaply. If no, they'll either decline or charge you more to cover the risk that you won't pay them back either.
The difference between a 620 credit score and a 750 credit score on a $30,000 car loan can be 5 to 10 percentage points in interest rate — meaning you could pay $200 to $400 more per month, or $12,000 to $24,000 more over a five-year loan. That's why understanding how your score affects your loan terms matters before you walk into a dealership.
Key Takeaways
- Credit scores typically range from 300 to 850, and most lenders require a minimum score between 580 and 620 to approve a car loan.
- Your interest rate drops significantly as your score rises — a 100-point improvement can lower your rate by 1 to 3 percentage points.
- You can check your own credit score for free through AnnualCreditReport.com or your bank, and checking it yourself does not harm your score.
- If your score is below 620, you may still find lenders, but you'll pay much higher rates or need a co-signer with better credit.
- Paying bills on time and lowering the amount you owe are the fastest ways to improve your score before you explore for a car loan.
How credit scores are built and what lenders see
Your credit score is calculated from five categories of information in your credit report. The most important is payment history — whether you've paid past debts on time. This makes up 35% of your score. A single late payment can drop your score 50 to 100 points; a missed payment or collection account can drop it 100 to 150 points.
The second-largest factor is credit utilization, which is how much of your available credit you're using right now. If you have a $5,000 credit card limit and you're carrying a $4,500 balance, your utilization is 90%, which hurts your score. Lenders see high utilization as a sign you're stretched thin financially. This makes up 30% of your score.
The remaining 35% comes from length of credit history (15%), credit mix — having different types of credit like credit cards, car loans, and mortgages (10%) — and recent hard inquiries, which happen when you explore for new credit (10%). Hard inquiries drop your score a few points each and stay on your report for two years.
When you explore for a car loan, the lender pulls your full credit report and calculates your score. They also look at your debt-to-income ratio — how much you already owe compared to how much you earn — to decide whether you can handle a new monthly payment.
What credit score range you need for a car loan
Most traditional lenders — banks and credit unions — require a credit score of at least 620 to 660 before they'll approve you for a car loan. Some require 700 or higher. If your score is below 620, you'll likely be turned down by mainstream lenders.
Subprime lenders, which specialize in lending to people with lower credit scores, will work with scores as low as 500 to 580. The trade-off is steep: interest rates from subprime lenders often run 10% to 20% or higher, compared to 4% to 8% for borrowers with good credit. Over five years, that difference adds up to tens of thousands of dollars.
Here's a rough picture of how rates change by score range, though the exact rate depends on the lender, the loan term, and the car's age:
| Credit Score Range | Typical Interest Rate | Lender Type |
|---|---|---|
| 750+ | 4% to 6% | Banks, credit unions |
| 700–749 | 6% to 8% | Banks, credit unions |
| 650–699 | 8% to 10% | Banks, credit unions, some dealers |
| 600–649 | 10% to 14% | Subprime lenders, some dealers |
| Below 600 | 14% to 20%+ | Subprime lenders, buy-here-pay-here dealers |
These are estimates and will vary by lender. The best way to know what rate you'll actually get is to shop around — get pre-approved quotes from at least three lenders before you go to a dealership.
How to check your credit score before you explore
You can check your credit score for free through several routes. AnnualCreditReport.com is the official government site where you can pull your credit report from all three bureaus — Equifax, Experian, and TransUnion — once per year at no cost. Your report shows your payment history, current debts, and accounts in your name, but it doesn't include your numerical score.
To see your actual credit score, you can use free tools offered by your bank or credit card issuer. Most major banks and card companies now show your score for free in your online account or mobile app. You can also use free services like Credit Karma or Credit Sesame, which update your score monthly and show you which factors are helping or hurting it most.
Checking your own credit score does not harm it. Only hard inquiries — when a lender pulls your report because you've applied for credit — lower your score. Checking your own score is a soft inquiry and has no impact.
Once you have your score, you'll know which lenders to target. If your score is below 620, focus on credit unions and subprime lenders rather than wasting time with banks that won't approve you. If your score is 650 or higher, you have options at traditional lenders and can shop for the best rate.
The fastest ways to improve your score before explore
If your score is lower than you'd like, you don't have to explore for a car loan when ready. Spending two to six months improving your score can save you thousands in interest. The fastest moves are:
Pay down credit card balances. If you're carrying high balances, paying them down lowers your credit utilization when ready. Paying a $4,500 balance down to $1,500 on a $5,000 card drops your utilization from 90% to 30%, which can raise your score 50 to 100 points within a month. You don't have to pay off the card entirely — just get the balance below 30% of your limit.
Make all payments on time for the next few months. Payment history is 35% of your score. One on-time payment doesn't erase a late one, but a string of on-time payments shows lenders you've turned a corner. Three to six months of clean payment history can raise your score 30 to 50 points.
Don't close old credit cards. Closing a card lowers your total available credit, which raises your utilization ratio and shortens your average credit history. Keep old cards open and paid down instead.
Don't explore for new credit while you're improving your score. Each process triggers a hard inquiry, which drops your score a few points. Wait until your score is where you want it, then explore for your car loan.
What happens if your score is too low
If your score is below 580 and you need a car loan now, you have three options, each with trade-offs.
Find a co-signer. A co-signer is someone with better credit who agrees to pay the loan if you don't. Lenders will approve you based partly on the co-signer's score and income. The downside: if you miss a payment, it damages both your credit and theirs, and the co-signer is legally responsible for the full debt.
Work with a subprime lender or buy-here-pay-here dealer. These lenders specialize in people with poor credit and will approve you, but at very high interest rates — often 15% to 25% or more. Some buy-here-pay-here dealers require you to make weekly or bi-weekly payments in person and use GPS tracking on the car. Read the contract carefully before signing.
Wait and improve your score first. This is the most expensive option in the short term but the cheapest long-term. Spending three months paying down debt and making on-time payments can raise your score 50 to 100 points, which could lower your interest rate by 3 to 5 percentage points — saving you thousands over the life of the loan.
How to shop for the best rate with your credit score
Once you know your credit score, get pre-approved quotes from at least three lenders before you visit a dealership. Pre-approval means the lender has reviewed your credit and given you a rate and loan amount you can count on. Pre-approvals typically last 30 to 60 days.
Contact your bank, your credit union, and one online lender like LendingClub or Upstart. Tell each one the car price, the loan term you want (typically 36, 48, or 60 months), and whether you have a down payment. They'll give you a rate based on your credit score and income.
Compare the rates side by side. A difference of 1% might not sound like much, but on a $25,000 loan over five years, it's about $1,300 in extra interest. Once you've chosen the best rate, you can take that pre-approval to a dealership. Dealers sometimes offer their own financing, but you're never required to use it — you can decline and use your pre-approved loan instead.
Frequently Asked Questions
Does explore for a car loan hurt my credit score?
Yes, but only temporarily. Each process triggers a hard inquiry, which drops your score 5 to 10 points. However, if you explore to multiple lenders within 14 days, the inquiries typically count as one inquiry for scoring purposes. The impact fades after a few months, and once you make on-time payments on the new loan, your score usually recovers within six months.
Can I get a car loan with no credit history?
It's difficult but possible. Lenders have no payment history to judge you by, so they'll often require a larger down payment, a co-signer, or both. Credit unions are usually more willing to work with people who have no credit history than banks are. Building credit with a secured credit card first — one backed by a cash deposit — can help you establish a score before you explore for a car loan.
What if my credit score drops after I'm approved but before I close the loan?
Most lenders lock in your rate once you're pre-approved, so a score drop won't change it. However, if your score drops significantly — say, because you missed a payment or opened new accounts — the lender may pull your credit again before closing and could rescind the offer. Avoid any new credit applications or missed payments between pre-approval and closing.
Does paying cash for a car affect my credit score?
No. Paying cash doesn't help or hurt your credit score because there's no credit involved. If you're trying to build or improve your credit, taking out a car loan and making on-time payments actually helps more than paying cash, because it adds a positive account to your credit mix and shows lenders you can handle installment debt responsibly.
How long does a late payment stay on my credit report?
A late payment stays on your credit report for seven years from the date you first missed the payment. However, its impact on your score decreases over time. A late payment from two years ago hurts your score much less than a late payment from two months ago. This is why recent payment history matters more than old history.
