Car Refinancing Rates: What to Expect
If you took out an auto loan a few years ago, your interest rate might be costing you thousands. Car refinancing—replacing your existing loan with a new one at a lower rate—can save you real money. But what rates can you actually expect? That depends on your credit score, the lender, and today's market conditions.
Average Car Refinancing Rates by Credit Score
Lenders set refinancing rates based primarily on your credit score. Here's what you can generally expect:
Excellent credit (740+): 4.5–6.5% APR Good credit (670–739): 6.0–8.5% APR Fair credit (580–669): 8.0–12.0% APR Poor credit (below 580): 12.0–16.0%+ APR
These are approximate ranges. Individual lenders vary, and market conditions shift monthly. The gap between what someone with excellent credit pays and what someone with poor credit pays can be significant—potentially thousands in interest over the life of the car loan.
If your credit score has improved since your original loan, refinancing could mean a substantial rate drop.
When Does Refinancing Make Sense?
Not every refinance is worth it. Consider refinancing if:
Your credit score has improved. If you've built credit since your original loan, you likely qualify for a lower rate. Even a 1-2% reduction saves hundreds or thousands.
Interest rates have dropped. Market rates fluctuate. If the prime rate is significantly lower than when you borrowed, it's worth comparing refinance offers. Understanding the difference between interest rate and APR can help you evaluate offers accurately.
You want to shorten your loan term. Refinancing into a 3-year loan instead of 5 years means paying less interest overall, though your monthly payment will increase.
You want to lower your monthly payment. Refinancing into a longer term reduces your payment, though you'll pay more interest overall. This is useful if cash flow is tight.
Skip refinancing if you're very close to paying off your loan or if refinancing fees eat up your savings.
How to Get the Best Refinancing Rate
Shop around. Don't accept the first offer. Banks, credit unions, and online lenders all have different rates. Get quotes from at least 3–5 lenders. An auto loan marketplace like myAutoloan lets you compare refi offers from 20+ lenders with a single form—no separate applications needed.
Check your credit score first. Know where you stand before applying. Many lenders offer free credit score checks.
Improve your credit before applying. If you're planning to refinance soon, delay the application a few months to pay down high credit card balances or fix any errors on your credit report. Even small score improvements can mean better rates.
Consider a credit union. Credit unions often offer lower rates than banks, especially if you have a membership. Working with a credit union or other alternative lender can yield better terms.
Get pre-approval offers. These typically don't require a hard credit pull and let you compare rates without the commitment.
Watch out for fees. Some lenders charge application, appraisal, or prepayment penalty fees. Calculate the total cost, not just the rate.
Impact on Your Credit
Refinancing affects your credit in both positive and negative ways:
Hard inquiry. When you apply for a refinance, lenders check your credit score (a hard inquiry). This typically drops your score by a few points temporarily.
New account. Your new loan creates a new account, which lowers the average age of your accounts—another small, temporary hit.
Improved credit mix. If you're adding installment loan diversity, this can actually help your credit over time.
On-time payments. Making consistent payments on your refinanced loan rebuilds credit and offsets the initial dip.
The impact is usually short-term. Within 6–12 months of making on-time payments, your score often bounces back higher than before, especially if the lower payment helps you manage your budget better.
Should You Refinance?
Refinancing makes sense if the savings outweigh the costs and hassle. Use a refinance calculator online to see exact numbers for your situation. If refinancing saves you $1,000+ over the remaining life of the loan, it's usually worth the effort.

Frequently Asked Questions
What credit score do I need to refinance a car loan? Most lenders prefer a credit score of 600 or higher for auto refinancing. However, the best rates go to borrowers with scores of 700+. If your score has improved significantly since you took out your original loan, refinancing can yield meaningful savings even if your score isn't perfect.
When is the best time to refinance a car loan? The best time to refinance is when your credit score has improved since your original loan, when market interest rates have dropped, or when you're early in your loan term (before you've paid most of the interest). Avoid refinancing if you're more than halfway through repayment or if you're close to paying it off.
Does refinancing a car hurt your credit score? Briefly, yes. Applying for refinancing triggers a hard inquiry, which temporarily reduces your score by 5–10 points. A new account also lowers your average account age slightly. Both effects are temporary—consistent on-time payments on the refinanced loan typically outweigh the initial dip within 6–12 months.
How much can refinancing a car save me? Savings depend on your loan balance, current rate, new rate, and remaining term. For example, refinancing a $15,000 balance from 12% to 7% APR over 36 months saves approximately $1,200 in interest. Use an online auto refinance calculator to see exact numbers for your situation.
Can I refinance a car loan with bad credit? Yes, but your options are limited and rates will be higher. If your credit has improved even slightly since your original loan, you may still qualify for a better rate. Credit unions are often more flexible than banks for borrowers with fair or poor credit. Building credit before refinancing—even by a few months—can make a meaningful difference in the rate you're offered.
