Car refinancing happens through banks, credit unions, and online lenders — not through your current lender

When you refinance a car, you take out a new loan from a different lender to pay off your existing car loan. The new lender sends money directly to your current lender to close that loan, and you then owe the new lender instead. You keep the same car and the same lender does not have to agree — the new lender handles the payoff on your behalf.

The places that offer car refinancing are the same places that offer original car loans: banks, credit unions, and online lenders. Each has different approval standards, interest rates, and how quickly they move. Where you refinance matters because the rate you receive can vary by several percentage points depending on the lender, your credit score, and the age of your car.

Key Takeaways

  • Banks, credit unions, and online lenders all refinance cars, and rates vary significantly between them — getting quotes from at least three lenders helps you compare.
  • Credit unions typically offer lower rates than banks if you are a member, but you must join first and membership requirements vary by location and employer.
  • Online lenders move faster than traditional banks but may charge higher rates, and some specialize in people with lower credit scores.
  • Your car's age, mileage, and condition affect whether a lender will refinance it — most lenders have a cutoff around 10 years old or 100,000 miles.
  • You will need your current loan details, proof of income, and a clear title to the car before you contact any lender.

Banks and what to expect from them

Traditional banks refinance cars, but they move slowly and have strict approval standards. Most banks want a credit score of 650 or higher, a car that is less than 10 years old, and proof that you have been employed for at least two years. They also typically require that you have paid down at least 20 percent of your original loan before they will refinance.

The advantage of a bank is that rates are often competitive if your credit is good, and you may already have a relationship with them that speeds up the process. The disadvantage is that approval can take two to four weeks, and if your credit score is below 650 or your car is older, many banks will decline you outright. Call your current bank first to ask whether they refinance cars and what their requirements are — some do not offer this service at all.

Credit unions and membership requirements

Credit unions almost always offer lower rates than banks for car refinancing, sometimes by 1 to 2 percentage points. They also tend to have more flexible approval standards and will work with people whose credit is fair rather than excellent. The catch is that you must be a member of the credit union before you can refinance through them.

Membership requirements vary. Some credit unions are open to anyone who lives or works in a specific county. Others require that you work for a particular employer, belong to a certain profession, or are related to someone who already belongs. Start by searching for credit unions in your area using the CO-OP Network locator or Alliant Credit Union's locator tool — both show which unions will accept you based on where you live or work. Once you join, you can refinance when ready, and the process typically takes one to two weeks.

Online lenders and faster timelines

Online lenders like LendingClub, Upgrade, and Lightstream refinance cars and often provide decisions within 24 to 48 hours. They handle everything by phone and email, so you never visit a physical location. Many online lenders also work with people whose credit is fair or poor, making them an option if traditional banks have declined you.

The trade-off is that online lenders' rates are often higher than banks or credit unions, especially if your credit score is below 700. Some online lenders also charge origination fees (typically 1 to 5 percent of the loan amount) that get added to what you owe. Read the full loan agreement before you accept an offer, because the lowest advertised rate may not be the rate you actually receive. Online lenders are most useful when you need money quickly or when your credit makes you ineligible elsewhere.

Comparing rates and what documents you need

Before you contact any lender, gather your current loan documents, a recent pay stub, and your car's title. You will also need the current payoff amount on your existing loan — call your current lender and ask for this number, which is different from your current balance. Write down the car's year, make, model, mileage, and condition, because lenders ask for these details.

Contact at least three lenders and ask for a rate quote. Most lenders can give you a preliminary rate over the phone without a hard credit pull, which means it does not affect your credit score. Once you have three quotes, compare not just the interest rate but also the loan term (how many months you will pay), any fees, and how long approval takes. A lower rate over 72 months might cost you more in total interest than a slightly higher rate over 60 months — ask each lender for the total amount you will pay over the life of the loan.

Age and mileage limits that disqualify cars

Most lenders will not refinance a car that is more than 10 years old or has more than 100,000 miles, though some will go to 12 years or 120,000 miles. A few lenders specialize in older cars but charge significantly higher rates. If your car is at or near these limits, contact lenders before you spend time gathering documents — a quick phone call can tell you whether they will even consider your car.

The reason for these limits is that older cars are more likely to break down, which means you might stop paying the loan while the car is worthless. Lenders protect themselves by refusing to finance cars they consider too risky. If your car is too old for traditional refinancing, you may be stuck with your current loan, or you may need to look into a personal loan instead (which does not require the car as collateral but typically has a higher interest rate).

What happens after you are approved

Once a lender approves you, they will send the funds directly to your current lender to pay off your existing loan. This usually takes three to seven business days. During this time, you still owe your original lender, so keep making payments on schedule unless the new lender tells you to stop. Once the payoff is complete, your original lender will send you a release of lien, which means they no longer have a claim on the car.

You will then owe the new lender instead, and your monthly payment will change based on the new interest rate and loan term. The new lender will send you a loan agreement and payment instructions. If you refinanced to a lower rate, your monthly payment will likely drop. If you extended the loan term to lower the payment, you will pay more interest overall even if the rate is lower — this is why comparing the total cost matters, not just the monthly payment.

Frequently Asked Questions

Can I refinance a car I still owe money on?

Yes — that is the entire point of refinancing. The new lender pays off what you still owe, and you then owe them instead. You do not need permission from your current lender. The only requirement is that the car's value is at least as much as what you still owe (called being "right-side up" on the loan).

Will refinancing hurt my credit score?

A hard credit pull (which happens when you formally explore) will lower your score by a few points temporarily. However, if you get quotes from multiple lenders within a two-week window, most credit scoring models count them as a single inquiry. Your score will recover within a few months, especially if you make on-time payments on the new loan.

What if my car is worth less than what I owe?

Most lenders will not refinance if you are underwater on the loan, because they have no collateral if you stop paying. Some credit unions and online lenders will refinance the difference as an unsecured loan, but the rate will be higher. Your other option is to pay down the loan until you owe less than the car is worth.

How long does the whole refinancing process take?

Online lenders typically take one to two weeks from process to funding. Banks usually take two to four weeks. Credit unions fall in the middle at one to three weeks. The payoff of your old loan happens after funding, which adds another three to seven business days before you officially owe the new lender.

Should I refinance if I only have a year or two left on my loan?

Probably not. Refinancing costs time and involves a credit inquiry, and the savings need to be large enough to justify that. If you have less than 18 months left, the interest you save is usually too small to matter. Calculate the total interest you will pay under both scenarios before you decide.
