Refinancing means replacing your current car loan with a new one, usually at a lower interest rate
When you refinance, you pay off your existing loan with money from a new lender, then make payments to that new lender instead. The goal is usually to lower your monthly payment, reduce the total interest you pay over the life of the loan, or both. You keep the same car — refinancing is about the loan, not the vehicle itself.
Refinancing makes the most sense if your credit score has improved since you took out the original loan, if interest rates have dropped, or if you're struggling with your current payment. It can also help if you're paying a high rate because you had limited credit history or a lower score when you first borrowed.
Key Takeaways
- Refinancing works best when your credit score has risen or when current interest rates are lower than the rate on your existing loan.
- You'll need your current loan details, proof of income, and proof of insurance before you contact a lender.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary significantly between them.
- The process typically takes one to two weeks from process to funding, though some lenders are faster.
- Refinancing costs money upfront (title transfer fees, document fees) and resets your loan timeline, so calculate whether the monthly savings justify the cost.
Check your credit score and current loan terms first
Before you contact any lender, pull your credit report and check your credit score. You can get your credit report free once per year from AnnualCreditReport.com, which is the official site run by the three major credit bureaus. Your score determines what interest rate you'll be offered, so knowing it in advance helps you understand whether refinancing will actually save you money.
Next, gather the details of your current loan: the remaining balance, your current interest rate, and how many months are left to pay. You can find this on your loan statement or by calling your current lender. Calculate roughly how much you'll pay in total interest if you keep the loan as-is. This number is your baseline — any new loan should cost less in total interest, or have a lower monthly payment, to be worth refinancing.
Check your car's value using Kelley Blue Book or NADA Guides. Most lenders won't refinance a car worth significantly less than what you still owe on it, so knowing this number tells you whether you're even may be able to access.
Gather documents before you explore
Lenders will ask for the same basic information regardless of where you explore. Have these ready: your driver's license, proof of current auto insurance, your most recent pay stub, and your most recent tax return or W-2. You'll also need your current loan documents or the account number for your existing loan.
Some lenders ask for proof of residence (a utility bill or lease) and your vehicle identification number (VIN), which is on your registration or visible on the dashboard. Having everything prepared before you start applications speeds up the process and means you won't have to gather documents multiple times if you explore to more than one lender.
Compare rates from banks, credit unions, and online lenders
Interest rates for car refinancing vary widely depending on the lender and your credit profile. Banks like Chase and Wells Fargo offer refinancing, as do most credit unions if you're a member. Online lenders like LendingClub, Upstart, and SoFi also refinance car loans, and some specialize in it.
Contact at least three lenders and ask for a rate quote. Most will give you an estimate without a hard credit pull, which means it won't affect your credit score. A hard pull happens only when you formally explore. Comparing quotes takes an hour or two and can save you hundreds of dollars over the life of the loan.
When you compare, look at the interest rate, the loan term (how many months to pay it back), and any fees. Some lenders charge an origination fee, a document fee, or a title transfer fee. Ask each lender for the total cost of the loan, not just the monthly payment — a longer loan term lowers your payment but costs more in interest overall.
Understand the costs and timeline of refinancing
Refinancing is not free. You'll typically pay a title transfer fee (usually $50 to $200, depending on your state), and some lenders charge an origination fee (typically 1 to 5 percent of the loan amount). A few lenders advertise no fees, but read the fine print — they may straightforward roll the fees into the loan amount, which means you pay interest on them.
Calculate your break-even point: add up all the fees, then divide by your monthly savings. If your new payment is $50 lower per month and refinancing costs $300, you break even after six months. If you plan to keep the car longer than that, refinancing makes financial sense. If you're selling or trading the car soon, the fees may not be worth it.
The refinancing process typically takes one to two weeks from the time you submit your process to the time the new lender pays off your old loan and you start making payments to them. Some online lenders are faster — a few fund within three to five business days. During this time, you continue paying your original lender as usual.
explore to your chosen lender and complete the process
Once you've chosen a lender, you'll submit a formal process. This triggers a hard credit pull, which temporarily lowers your credit score by a few points. If you're explore to multiple lenders, do it within a two-week window — multiple hard pulls in a short time count as a single inquiry for credit scoring purposes.
After you explore, the lender will contact your current lender to get your exact payoff amount (the total you owe right now, including any interest accrued). They'll prepare loan documents for you to sign, usually electronically. You'll need to provide proof of insurance — most lenders require this before they'll fund the loan.
Once everything is signed, the new lender sends money directly to your old lender to pay off the loan. Your old lender releases the title, and the new lender files the title in their name. You'll receive new loan documents and payment instructions from your new lender, and your first payment to them is due according to the schedule they provide.
Decide whether to refinance for a lower payment or a shorter timeline
When you refinance, you can choose a new loan term. Many people refinance into a shorter loan (say, from 72 months to 48 months) to pay off the car faster, or into a longer loan to lower the monthly payment. A longer loan means more interest paid overall, but a lower payment each month. A shorter loan costs less in interest but raises your payment.
If your goal is to save money overall, choose the shortest term you can afford. If your goal is to free up cash flow each month, choose a longer term — but understand that you're paying more interest to do it. Some people refinance into a shorter term when their credit improves, because the lower interest rate makes the higher payment manageable.
Frequently Asked Questions
Can I refinance if I'm underwater on my car loan?
Being underwater means you owe more than the car is worth. Most lenders won't refinance in this situation because they have no collateral if you default. Some credit unions and specialized lenders will, but usually only if you have strong credit and a stable income. Call your credit union first — they're more flexible than banks.
Will refinancing hurt my credit score?
The hard credit pull lowers your score by a few points temporarily, usually recovering within a few months. Refinancing also resets your loan age, which can lower your score slightly. However, if refinancing lowers your overall debt or improves your payment history, your score will recover and improve over time.
What if my current lender won't release the title?
This is rare, but it happens. Your new lender handles the payoff and title transfer — they'll contact your old lender directly. If there's a problem, your new lender's title department will work it out. You don't have to contact your old lender yourself; the new lender manages the entire handoff.
How soon after refinancing can I refinance again?
Technically you can refinance anytime, but most lenders won't refinance a loan less than six months old. Refinancing twice in a short period costs you in fees and credit inquiries without much benefit. Wait at least a year, or until interest rates drop significantly, before refinancing a second time.
What happens to my old loan documents?
Your old lender will send you a final statement showing the loan is paid in full. Keep this for your records. Your new lender will send you new loan documents and a payment coupon or online payment instructions. Shred or securely destroy the old documents once you've confirmed the payoff with your old lender.
