Refinancing a car can cause a small, temporary dip in your credit score. That usually happens when a lender runs a hard credit check after you formally apply for a new loan.
But checking refinance rates does not always hurt your credit. With Caribou, you can check your rate with a soft credit pull, which does not affect your credit score. If you decide to move forward with a lender offer, the lender may run a hard credit pull as part of the application process.
For many borrowers, the short-term credit impact may be worth it if refinancing helps lower your APR, reduce your monthly payment or make your car loan easier to manage.
Why refinancing could lower your score
Refinancing replaces your current auto loan with a new one. During that process, your credit score can be affected in two main ways:
A lender may run a hard credit check
A hard credit check, also called a hard inquiry, may happen when you formally apply for a loan. A hard inquiry can cause a small, temporary drop in your credit score.
The impact is usually minor, but it depends on your full credit profile. If you already have several recent credit applications, another hard inquiry may have a bigger effect.
Your old loan is paid off and a new loan is opened
Refinancing closes your original auto loan and opens a new one. That can temporarily change the average age of your accounts and add new activity to your credit report.
This does not mean refinancing is bad for your credit. It just means your credit report may show a change for a short time.
Your payment history still matters most
The most important thing is whether you keep making payments on time. If refinancing gives you a more manageable monthly payment, it may help you stay current on your loan.
That’s why it helps to look at the full picture before you apply. The pros and cons of refinancing your car loan can depend on your rate, payment, loan term and credit situation.
Will checking refinance rates hurt your credit?
Checking refinance rates does not have to hurt your credit.
Many lenders and marketplaces use a soft credit pull to show estimated rates. A soft pull lets you compare options without affecting your credit score.
With Caribou, checking your rate uses a soft credit pull. Your credit score will not be affected just because you look at your options.
A hard credit pull may happen later if you choose a lender offer and submit a formal application.
If you’re comparing options, it can help to understand how auto refinance pre-qualification works before you move forward.

Soft pull vs. hard pull
Here’s the simple difference between a soft credit pull and a hard credit pull:
| Credit check type | When it usually happens | Credit score impact |
|---|---|---|
| Soft pull | When you check rates or prequalify | Does not affect your credit score |
| Hard pull | When you formally apply with a lender | May temporarily lower your credit score |
The key thing to know is that checking your options is not the same as completing a full loan application.
How much can refinancing lower your credit score?
For most people, the drop is small. A hard credit inquiry may lower your score by a few points, but the effect is usually temporary.
Your score may also change slightly because your old loan is closed and your new loan is added to your credit report.
That does not mean refinancing is bad for your credit. If you make your new payments on time, the impact may fade as the loan ages and you build a positive payment history.
How long does refinancing affect your credit?
A hard inquiry can stay on your credit report for up to two years, but it usually affects your score for less time than that.
The bigger factor is what you do after refinancing. Making on-time payments, avoiding missed payments and not applying for too much new credit at once can help your score recover over time.
Can refinancing help your credit?
Refinancing does not automatically improve your credit score. But it may help your credit over time if the new loan makes your payment easier to afford.
For example, refinancing may help if it gives you:
- A lower monthly payment.
- A lower APR.
- A loan term that better fits your budget.
- More breathing room to avoid missed payments.
Payment history is one of the biggest factors in your credit score. If refinancing helps you pay on time, that can be good for your credit in the long run.
When refinancing may be worth the credit dip
A small, temporary credit dip may be worth it if refinancing helps you lower your rate, reduce your payment or make your loan easier to manage.
Refinancing may make sense if:
- Your credit score has improved since you got your original loan.
- Interest rates are lower than when you first borrowed.
- Your current monthly payment is too high.
- You want to remove or add a co-borrower.
- You can qualify for a lower APR or better loan terms.
- You want to compare offers without affecting your score.
If your main goal is a more affordable monthly payment, refinancing is one option. You can also look at other ways to decrease your car payment depending on your loan, budget and vehicle.
When you may want to wait
Refinancing is not always the right move right away.
You may want to wait if:
- You’re about to apply for a mortgage.
- You recently opened several new credit accounts.
- Your credit score recently dropped.
- You are behind on your current auto loan.
- You are unlikely to qualify for a better rate.
- The new loan would stretch your debt out too long.
Timing matters. For example, if you’re planning to buy a home soon, a new hard inquiry and new loan account may matter during the mortgage process. Before making a decision, it may be worth reading more about whether you should refinance your car before buying a house.
How to reduce the credit impact of refinancing
You can take a few steps to limit the credit impact of refinancing.
Check rates with a soft pull first
Start by checking rates in a way that does not affect your credit score. This helps you see whether refinancing may be worth it before you formally apply.
Compare offers in a short window
If you decide to formally apply, try to do your rate shopping in a short period of time. Credit scoring models may treat multiple auto loan inquiries as one inquiry when they happen close together.
Avoid applying for other credit at the same time
Try not to apply for multiple credit cards, personal loans or other financing while you’re refinancing your car. Too many new applications can make you look riskier to lenders.
Keep making payments on your current loan
Do not stop paying your current loan while you’re waiting for the refinance to be completed. Keep making payments until your old lender confirms that the loan has been paid off.
What if your credit score is low?
You may still be able to refinance with a lower credit score, but your options may be more limited.
Lenders usually consider more than your credit score. They may also look at your income, payment history, loan balance, vehicle value, mileage and current loan terms.
If your credit has improved since you first got your loan, refinancing may be worth checking. If your credit has gone down, you may not qualify for a better rate right away.
That does not always mean refinancing is off the table. Here’s what to know if you want to refinance an auto loan with bad credit.
Does refinancing restart your loan?
Refinancing replaces your current loan with a new one. That means you may get a new rate, new monthly payment and new loan term.
A longer loan term can lower your monthly payment, but it may also increase the total interest you pay over time. Before refinancing, compare your monthly savings with your total loan cost.
That’s where loan length matters. Understanding how loan terms affect the cost of credit can help you avoid choosing a lower payment that costs more in the long run.
Bottom line
Refinancing your car may cause a small, temporary dip in your credit score. But checking your rate through Caribou uses a soft credit pull, so you can compare options without affecting your score.
If refinancing helps you lower your APR, reduce your monthly payment or make your loan easier to manage, the short-term credit impact may be worth it. Just make sure you compare the full cost of the new loan, not only the monthly payment.
