Car loan refinancing replaces your current auto loan with a new one that has better terms. You keep the same car but get a different interest rate, monthly payment, or loan length.
The process is straightforward: a new lender pays off your existing auto loan, and you start making payments to them instead. If rates have dropped since you bought your car, or your credit score has improved, you could save a significant amount of money.
Borrowers who refinanced their car loans in Q3 2025 saved an average of 2.08 percentage points on their interest rate, according to Experian. That translates to roughly $77 per month in savings for the average borrower. Some refinancing platforms report even higher savings, with customers reducing their monthly payments by $141 on average.
This guide walks you through everything you need to know about car loan refinancing: when it makes sense, what it costs, and a step-by-step process to get the best deal.
Why Refinance Your Car Loan?
There are four main reasons borrowers refinance their auto loans. Each one can put real money back in your pocket, depending on your situation.
Lower your interest rate. If your credit score improved or market rates dropped, you could qualify for a significantly lower rate. Even a 1-2% rate reduction on a $25,000 loan saves hundreds over the life of the loan.
Reduce your monthly payment. Refinancing to a lower rate or longer term brings your monthly payment down. This frees up cash for other expenses or savings.
Shorten your loan term. Want to pay off your car faster? Refinancing from a 60-month to a 36-month term means you own the car sooner and pay less total interest.
Remove or add a co-signer. If your financial situation has changed, refinancing lets you restructure who is responsible for the loan.
Current Car Loan Refinancing Rates
Auto loan refinancing rates vary widely based on your credit score, loan amount, and vehicle age. Here is what borrowers can expect in 2026.
The average 60-month new car loan rate sits at 6.93%, the first time it has dropped below 7% since June 2023. Refinance rates follow similar patterns.
Credit score is the single biggest factor in the rate you will get. Experian data from Q4 2025 shows the spread clearly:
| Credit Tier | Score Range | Avg. New Car Rate | Avg. Used Car Rate |
|---|---|---|---|
| Super Prime | 781+ | 4.66% | 5.67% |
| Prime | 661-780 | 6.57% | 8.41% |
| Near Prime | 601-660 | 9.49% | 12.03% |
| Subprime | 501-600 | 12.28% | 16.54% |
| Deep Subprime | 300-500 | 16.01% | 20.64% |
Rate outlook
Experts project auto loan rates will continue their gradual decline through 2026. The average 60-month new car loan rate could drop from around 7% to 6.40%, according to Bankrate's senior industry analyst. Even a small rate decline means savings for borrowers who refinance at the right time.
6 Steps to Refinance Your Car Loan
Follow these steps to refinance your auto loan and get the best available deal for your situation.
Check your credit score
Start by pulling your credit report from all three bureaus at AnnualCreditReport.com. Your credit score directly determines the interest rate you will be offered.
If your score has improved since you took out the original loan, you are in a strong position to refinance. If it has dropped, consider working on improving it first. Even a 20-30 point increase can move you into a better rate tier and save you hundreds of dollars.
Gather your documents
Collect everything you will need before applying:
- Proof of income (pay stubs or tax returns)
- Proof of residence (utility bill or lease agreement)
- Current auto insurance policy
- Current loan details (remaining balance, interest rate, term)
- Vehicle information (make, model, year, VIN, mileage)
- Driver's license
About 90% of lenders also require proof of insurance. Having everything ready upfront speeds up the process and prevents delays.
Compare rates from multiple lenders
This is the most important step. Do not accept the first offer you get.
Compare rates from banks, credit unions, and online lenders. Credit unions tend to offer the best refinance savings, with an average monthly reduction of $95, compared to $56 at banks and $18 at other finance companies (Experian Q3 2025 data).
When comparing, look beyond just the interest rate. Check for origination fees, prepayment penalties, and the total cost over the life of the loan. Use our car loan comparison tool to see multiple offers side by side.
Get pre-qualified
Most lenders offer pre-qualification, which lets you see potential rates without a hard credit pull. This is a soft inquiry that will not affect your score.
Apply for pre-qualification with several lenders within a 14-day window. Credit scoring models treat multiple auto loan inquiries within this period as a single inquiry, so you can shop around without worrying about your score taking multiple hits.
Submit your formal application
Once you have identified the best offer, submit a formal application. This will trigger a hard credit inquiry, which may temporarily lower your score by 5-10 points.
Double-check all information before submitting. Errors or inconsistencies can delay the process or result in denial.
Review and accept the offer
If approved, carefully review the new loan terms. Compare the new interest rate, monthly payment, loan duration, and total cost against your current loan. Make sure the numbers actually work in your favor.
Ask for clarification on anything you do not understand. Once you accept, the new lender pays off your old loan and you start making payments to them.
Car Loan Refinancing Requirements
Every lender has slightly different criteria, but most car loan refinancing lenders evaluate these factors:
Credit score: Most lenders want a minimum of 600, though some work with scores as low as 510-560. A higher score gets you better rates.
Payment history: Lenders expect you to be current on your existing loan payments. Many require at least 6 months of on-time payments.
Debt-to-income ratio: Your total monthly debt payments divided by your gross monthly income. Most lenders prefer this to be below 50%.
Loan amount range: Minimum refinance amounts typically fall between $3,000 and $7,500. Maximum amounts cap around $75,000 for most lenders.
Vehicle age and mileage: Older vehicles with high mileage may not qualify. Many lenders set limits, such as vehicles less than 10 years old with under 150,000 miles.
Loan-to-value ratio: Your loan balance should not exceed the car's current market value. Being "underwater" (owing more than the car is worth) makes refinancing harder.

When to Refinance Your Auto Loan
Timing matters. Refinancing at the right moment maximizes your savings, while refinancing at the wrong time can cost you money.
The sweet spot is 2-3 years into your loan. Auto loans front-load interest payments, so refinancing early lets you capture more savings. Refinancing within the first 6 months is usually too soon because lenders want to see a history of on-time payments. Refinancing in the last year of your loan is usually not worth it because you have already paid most of the interest.
Refinancing makes the most sense when:
- Your credit score has improved significantly since the original loan
- Market interest rates have dropped
- You need to lower your monthly payment due to a change in your financial situation
- You want to remove a co-signer from the loan
- You are unhappy with your current lender's service
Avoid refinancing when rates are higher than your current rate, when your car is worth less than you owe, or when you are close to paying off the loan.
How Much Does It Cost to Refinance a Car Loan?
Unlike mortgage refinancing, auto loan refinancing has minimal upfront costs. Most lenders do not charge application or origination fees for car refinances. However, there are a few potential costs to watch for:
- Prepayment penalty: Some lenders charge a fee for paying off your current loan early. Check your existing loan agreement before refinancing.
- Title transfer fee: Your state may charge a fee to transfer the vehicle title from your old lender to the new one. This typically ranges from $5 to $75.
- Re-registration fee: Some states require you to re-register your car after refinancing, which carries a small fee.
- Sales tax (in some states): A handful of states charge sales tax on the refinanced amount.
These fees are usually small enough that the interest savings from refinancing still outweigh the costs. Some lenders roll the fees into the loan, so there is nothing to pay out of pocket. Use a car loan refinancing calculator to run the numbers and make sure you come out ahead after accounting for all fees.
Refinancing with Bad Credit
Refinancing a car loan with bad credit is possible, but it comes with trade-offs. Interest rates for borrowers with poor credit can be 10 percentage points or more above rates for those with excellent credit, which means your total cost could be significant.
Most lenders require a minimum credit score of 600 for refinancing, but some work with lower scores. iLending approves borrowers with FICO scores as low as 560, and requires just six months of credit history.
Options if your credit score is below 600
Add a co-signer with good credit to strengthen your application
Try credit unions, which tend to be more flexible than big banks
Explore lenders that specialize in car loans for bad credit
Work on improving your credit score first, then refinance once you qualify for better rates
Before refinancing with bad credit
Run the numbers carefully. If refinancing with bad credit means extending your loan term at a higher rate, you could end up paying more in total interest than your current loan. Only refinance if the new terms genuinely improve your situation.
Getting Preapproved for a Car Loan Refinance
Pre-qualification (also called pre-approval) is a critical step that many borrowers skip. Here is why it matters and how to do it right.
Check your credit report first. Review your credit report for errors that could be dragging your score down. Fixing inaccuracies could improve your rate offers.
Apply to multiple lenders within 14 days. Credit scoring models count all auto loan inquiries within a 14-day window as a single inquiry. Use this to your advantage.
Use credit unions. If you have an existing relationship with a bank or credit union, check their rates first. Members often get preferential pricing.
Compare the full picture. Look at the APR (not just the interest rate), fees, and total cost of the loan over its full term.
Consider a co-signer. If your credit is not ideal, a co-signer with strong credit can help you qualify for better terms. Both of you are responsible for the loan, so make sure you can handle the payments.
How Does Refinancing Affect Your Credit Score?
Refinancing your car loan will have a temporary, minor impact on your credit score. Here is what to expect:
The hard inquiry from your formal application typically lowers your score by 5-10 points. If you applied to multiple lenders within a 14-day window, it should count as a single inquiry.
Closing your old loan and opening a new one changes your credit mix and average account age, which can cause a small dip. However, if the refinance lowers your monthly payment and helps you stay current on all your debts, the long-term impact on your score is positive.
Most borrowers see their score recover within a few months. Over time, a car loan with consistent payments can actually raise your credit score.

Frequently Asked Questions
How does refinancing a car loan work?
Refinancing replaces your existing auto loan with a new one, typically from a different lender. The new lender pays off your old loan, and you start making payments to them. If you qualify for a lower interest rate, you save money on monthly payments and total interest. Borrowers who refinanced in Q3 2025 reduced their rate by an average of 2.08 percentage points.
Can you refinance a car loan with bad credit?
Yes, though your options are more limited and rates will be higher. Most lenders require a minimum credit score of 600, but some like iLending work with scores as low as 560. Adding a co-signer, using a credit union, or waiting to improve your score can help you get better terms.
How much can you save by refinancing your auto loan?
Average savings vary by lender type. Experian data shows borrowers save an average of $77 per month, with credit union refinances saving $95 per month. Over the life of a typical loan, refinancing saves borrowers roughly $1,000 to $2,200 in total interest.
Is refinancing your car loan a good idea?
It depends on your situation. Refinancing makes sense when interest rates have dropped, your credit score has improved, or you need lower monthly payments. It is not worth it if your current rate is already competitive, your car is nearly paid off, or you would extend the term so much that total interest increases.
How does refinancing a car loan affect your credit score?
Refinancing causes a temporary dip of 5-10 points from the hard credit inquiry. Closing the old loan and opening a new one also affects your credit mix and average account age. However, most borrowers see their score recover within a few months, and consistent payments on the new loan can improve your score over time.
What is the 2% rule for refinancing?
The 2% rule is a general guideline suggesting that refinancing is worth it if you can reduce your interest rate by at least 2 percentage points. For example, if your current rate is 8%, refinancing would make sense at 6% or lower. This is not a hard rule, though. Even a 1% reduction can save meaningful money on a large loan balance.
When is the best time to refinance a car loan?
The sweet spot is typically 2-3 years into your loan. You need at least 6 months of payment history for most lenders to consider you, and refinancing in the last year of your loan rarely saves enough to be worthwhile. Watch for rate drops, credit score improvements, or changes in your financial situation as triggers to start shopping.
