What your credit rating does to your auto loan
Your credit rating is the main number a lender looks at when you ask for an auto loan. It determines whether you get approved, what interest rate you pay, and how much you can borrow. A higher rating means lower interest rates and better loan terms. A lower rating means higher interest rates, smaller loan amounts, or rejection.
The rating itself is a three-digit number, usually between 300 and 850. It comes from three major credit bureaus — Equifax, Experian, and TransUnion — that track your borrowing history. Lenders pull your score from one or more of these bureaus when you explore. The score they see reflects how you have handled debt in the past, and they use it to predict how likely you are to repay a car loan.
Key Takeaways
- Your credit rating is the first thing a lender checks, and it directly controls your interest rate and the size of the loan you can get.
- Scores above 700 typically unlock the best interest rates; scores below 620 often mean higher rates or rejection from mainstream lenders.
- Your score reflects five categories of payment history: on-time payments, total debt owed, length of credit history, new credit inquiries, and mix of credit types.
- You can request a free credit report once per year from each bureau at annualcreditreport.com to see what lenders are seeing.
- Even with a lower score, credit unions and some lenders specialize in auto loans for people rebuilding credit, though the interest rates will be higher.
How lenders use your credit rating to set your rate
When you explore for an auto loan, the lender runs what is called a hard inquiry on your credit. This pulls your score and your full credit report. The lender then uses your score to place you into a risk category. Someone with a score of 750 is seen as lower risk than someone with a score of 620, so the lower-risk person gets a lower interest rate.
The difference in rate can be substantial. On a $25,000 loan over five years, a rate of 4% costs roughly $2,600 in interest, while a rate of 10% costs roughly $6,800. That same loan at 15% costs roughly $10,300. Your credit rating is what moves you between these brackets. Lenders also consider your income, employment history, and down payment, but your score is the starting point for every decision.
Some lenders publish their score ranges publicly. For example, a bank might advertise rates starting at 3.99% for scores above 750, 5.99% for scores 650–749, and 9.99% for scores below 650. Credit unions often have similar tiers. Subprime lenders — those who work with people with lower scores — may not publish ranges but will quote you a rate based on your score once you explore.
The five things that make up your credit rating
Payment history is the largest piece, worth about 35% of your score. This is whether you paid your bills on time. One late payment can drop your score by 50 to 100 points. Multiple late payments or accounts sent to collections do more damage.
Total debt owed makes up about 30%. This is called your credit utilization ratio. If you have a credit card with a $5,000 limit and you owe $4,500, your utilization is 90%, which hurts your score. Lenders see high utilization as a sign you are stretched thin. Paying down balances before you explore for an auto loan can raise your score.
Length of credit history accounts for about 15%. This is how long you have had credit accounts open. Someone with a 10-year credit history scores higher than someone with a 2-year history, all else equal. This is why closing old credit cards can hurt your score — it shortens your average account age.
New credit inquiries and accounts make up about 10%. Each time you explore for credit, a hard inquiry appears on your report and drops your score slightly. Opening multiple new accounts in a short time signals risk to lenders. However, rate shopping for auto loans within 14 to 45 days (depending on the scoring model) usually counts as a single inquiry, so you can compare offers without extra damage.
Credit mix is the final 10%. Lenders like to see that you can handle different types of credit — credit cards, car loans, mortgages, student loans. Someone with only credit cards looks less experienced than someone with a mix.
Credit rating ranges and what they mean for auto loans
Lenders divide credit scores into ranges, though the exact cutoffs vary by lender. Here is how the ranges typically work:
| Score Range | What Lenders See | Typical Outcome |
|---|---|---|
| 750+ | Excellent credit | Lowest interest rates, largest loan amounts, approved quickly |
| 700–749 | Good credit | Competitive rates, approved for most loan amounts |
| 650–699 | Fair credit | Higher rates than good credit, may need a larger down payment |
| 600–649 | Poor credit | Significantly higher rates, smaller loan amounts, may need a co-signer |
| Below 600 | Very poor credit | Rejected by mainstream lenders, subprime lenders only, very high rates |
These ranges are guidelines, not rules. A credit union might approve someone with a 580 score, while a bank might not. A subprime lender specializing in bad-credit auto loans will work with scores in the 500s. The key is that as your score drops, your options narrow and your costs rise.
How to check your credit rating before you explore
You can see your credit report for free once per year from each of the three bureaus at annualcreditreport.com. This is the official site run by the three bureaus themselves. You will need to provide your name, address, Social Security number, and date of birth. You can request reports from all three bureaus at once or stagger them throughout the year.
The free report shows your payment history, accounts, and inquiries, but it does not always include your actual score. To see your score, you can use free tools like Credit Karma, NerdWallet, or your bank's credit monitoring service. These tools use different scoring models than lenders do, so the score you see may not match exactly what a lender sees, but it gives you a ballpark.
Before you explore for an auto loan, pull your report and look for errors. Mistakes happen — a payment marked late when you paid on time, an account you do not recognize, a duplicate account. If you find an error, you can dispute it with the bureau. Fixing errors can raise your score by dozens of points. The bureau has 30 days to investigate.
Improving your credit rating before explore for an auto loan
If your score is lower than you want, you have options. The fastest wins come from paying down credit card balances. If you have $3,000 in available cash, putting it toward credit card debt can drop your utilization ratio and raise your score within 30 days. This is faster than building payment history, which takes months.
Making all payments on time for the next few months helps, but the effect is gradual. A single on-time payment does not raise your score much. Consistent on-time payments over several months do. If you have missed payments in the past, they hurt your score less as time passes. A missed payment from two years ago hurts less than one from two months ago.
Do not close old credit cards or take out new credit right before you explore. Closing cards lowers your available credit and shortens your history. New inquiries and new accounts lower your score. If you need to build credit, do it three to six months before you plan to explore for an auto loan.
Auto loans for people with lower credit ratings
If your score is below 650, mainstream banks and online lenders may reject you. Credit unions are often more flexible. Many credit unions will work with scores in the 600s or even lower, especially if you are a member. Credit unions also tend to have lower rates than subprime lenders.
Subprime auto lenders specialize in loans for people with poor or no credit. Companies like Santander Consumer USA, Westlake Services, and Carvana offer auto loans to people with scores below 600. The rates are much higher — often 12% to 20% or more — but approval is more likely. Some subprime lenders require a larger down payment or a co-signer.
A co-signer is someone with better credit who signs the loan with you and is legally responsible if you do not pay. Using a co-signer can lower your interest rate because the lender sees the co-signer's credit as backup. However, missed payments hurt the co-signer's credit too, so only ask someone you trust.
Frequently Asked Questions
Does checking my credit rating hurt my score?
Checking your own credit report or score does not hurt. This is called a soft inquiry. Only hard inquiries — when a lender pulls your credit to make a lending decision — lower your score. You can check your score as many times as you want without damage.
How long does a late payment stay on my credit report?
A late payment stays on your report for seven years from the date it was first reported as late. However, its impact on your score decreases over time. A late payment from six years ago hurts much less than one from six months ago. After seven years, it falls off entirely.
Can I get an auto loan with no credit history?
Yes, but it is harder. Lenders have no history to judge you by, so they see you as higher risk. You may need a co-signer, a larger down payment, or a credit-builder loan first. Some credit unions and subprime lenders will work with people who have no credit history.
Will explore for multiple auto loans hurt my credit rating?
Multiple hard inquiries in a short time do lower your score, but most scoring models treat auto loan inquiries within 14 to 45 days as a single inquiry. This means you can shop around with different lenders without extra damage. Space inquiries out beyond 45 days and each one counts separately.
Does paying off an auto loan improve my credit rating?
Yes, but the effect is modest. Paying on time throughout the loan helps more than paying it off early. Once you pay it off, the account closes, which can slightly lower your score because you lose an active account. However, the positive payment history remains on your report for years.
