What refinancing a car loan means and when it saves you money
Refinancing a car loan means replacing your current loan with a new one from a different lender. You pay off the old loan in full with money from the new lender, then make payments to the new lender instead. The new loan has its own interest rate, term length, and monthly payment.
Refinancing makes financial sense when the new interest rate is lower than what you're currently paying. A lower rate reduces your monthly payment, cuts the total interest you'll pay over the life of the loan, or both. The savings depend on how much lower the new rate is, how much time remains on your current loan, and how long you plan to keep the car.
You might also refinance to change the loan term — stretching payments over more months to lower your monthly bill, or shortening the term to pay off the car faster. Refinancing can also help if your credit score has improved since you took out the original loan, which often qualifies you for better rates.
Key Takeaways
- Refinancing works best when your new interest rate is at least 1 to 2 percentage points lower than your current rate, though even smaller drops can save money over time.
- You need to know your current loan balance, interest rate, and remaining term before shopping for a new loan, because lenders will ask for all three.
- The refinancing process typically takes 3 to 7 business days from process to funding, during which you keep making payments on your original loan.
- Refinancing costs include a credit check (usually free), title transfer fees (typically $50 to $300 depending on your state), and sometimes an early payoff penalty on your original loan.
- Refinancing makes less sense if you have only a few months left on your current loan, owe more than the car is worth, or have poor credit with no recent improvement.
How to find your current loan details and check your credit before shopping
Before you contact any lender, gather information about your existing loan. Log into your lender's website or app, call the customer service number on your loan statement, or request a payoff quote in writing. You need three numbers: your current loan balance (what you still owe), your interest rate, and how many months remain on the loan.
Check your credit report and credit score next. You can get your credit report free once per year from each of the three major bureaus — Equifax, Experian, and TransUnion — through AnnualCreditReport.com. Your credit score is separate; many banks and credit card issuers show your score free in their online accounts, or you can check it through services like Credit Karma or NerdWallet. Knowing your score before you explore helps you understand what rates you're likely to see and whether refinancing will actually improve your situation.
If your credit score has dropped since you took out the original loan, or if you have recent late payments, refinancing may not save you money — new lenders might offer rates higher than what you're already paying. If your score has improved, you're in a stronger position to negotiate better terms.
Where to shop for a refinance loan and what to compare
You can refinance through banks, credit unions, online lenders, and sometimes your current lender. Each type has different approval standards and rates. Credit unions often offer lower rates to members, but you must be a member to borrow. Banks and online lenders typically have faster process processes and wider geographic reach. Your current lender may offer a streamlined refinance with less paperwork since they already have your information.
Get quotes from at least three lenders before deciding. When you request a quote, lenders will perform a soft credit inquiry (which doesn't hurt your score) or a hard inquiry (which does, but only by a few points). Multiple hard inquiries within 14 to 45 days usually count as a single inquiry for credit scoring purposes, so shopping around in a short window minimizes the damage.
Compare these numbers across quotes: the interest rate, the loan term in months, the monthly payment, and the total amount you'll pay over the life of the loan. Use an online auto refinance calculator to see how much you'll save overall, not just on the monthly payment. A longer term might lower your payment but cost you more in total interest.
Costs and fees involved in refinancing
Refinancing is not free, though some costs are smaller than others. A credit check is usually free. Your new lender will order a title search and handle the paperwork to transfer the lien from your old lender to the new one; this typically costs $50 to $300 depending on your state and lender. Some lenders roll this fee into the loan, others charge it upfront.
Check whether your current loan has an early payoff penalty — a fee charged if you pay off the loan before the term ends. This is less common now than it once was, but some lenders still use them. Your loan documents or a call to your lender will tell you whether one applies. If the penalty is large, factor it into your savings calculation; sometimes the penalty eats up most or all of the benefit from a lower rate.
You may also incur a small fee if your new lender requires a vehicle inspection or appraisal, though many online lenders skip this step. Ask each lender upfront what fees explore to your situation so you can compare the true cost of refinancing, not just the interest rate.
The refinancing timeline and what happens to your current loan
Once you've chosen a lender and been approved, the refinancing process usually takes 3 to 7 business days. Your new lender will order the title, contact your current lender to request a payoff quote, and prepare the new loan documents. You'll sign the paperwork (often electronically) and the new lender will send the payoff amount directly to your old lender.
During this time, keep making your regular payment to your original lender on schedule. Your old loan doesn't close until the new lender's money arrives and pays it off. Missing a payment during the refinance window can damage your credit and may cause the new lender to back out of the deal.
Once the refinance is complete, your old loan is closed and you'll receive a title release from the original lender. Your new lender will hold the title as security for the new loan. You'll start making payments to the new lender according to the new loan's schedule.
When refinancing doesn't make financial sense
Refinancing is not the right move in several situations. If you have only a few months left on your current loan, the savings from a lower rate won't offset the refinancing costs. As a rough rule, you need at least 12 to 24 months remaining to make refinancing worthwhile, though this depends on how much lower the new rate is.
If you owe more than the car is worth — called being "underwater" on the loan — refinancing becomes harder. Some lenders won't refinance an underwater loan at all. Others will, but at a higher rate because the risk is greater. You can check your car's value using Kelley Blue Book or NADA Guides and compare it to your loan balance.
If your credit has not improved since you took out the original loan, or if you've had recent late payments, new lenders may offer rates higher than your current rate. In that case, refinancing would cost you money rather than save it. Wait until your credit improves before trying again.
Refinancing versus other ways to lower your car payment
Refinancing is one option, but not the only one. If your current lender is willing, you can sometimes modify your existing loan — extending the term to lower the payment without going through a full refinance. This is faster and involves fewer fees, but you'll pay more interest overall because you're spreading payments over more months.
If refinancing isn't available to you, you might also consider selling the car and buying a less expensive one, or using a side income to pay down the loan faster. These are more drastic steps, but they're worth considering if refinancing won't help or if you're struggling with the payment.
Frequently Asked Questions
Will refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score when the lender performs a hard inquiry and opens a new account. The dip is usually 5 to 10 points and recovers within a few months. The long-term benefit of a lower interest rate and on-time payments to the new lender typically outweighs this short-term impact.
Can I refinance if I'm behind on payments?
Most lenders will not refinance a loan if you're currently behind on payments. You'll need to bring the account current first. Some lenders may reconsider after you've made several on-time payments in a row, but this varies by lender.
What if my car has a lot of miles or is very old?
Some lenders have age or mileage limits — for example, they may not refinance cars older than 10 years or with more than 120,000 miles. Check with lenders upfront about their vehicle requirements. Credit unions and some online lenders are often more flexible than traditional banks on older vehicles.
Do I need to have the car inspected or appraised for refinancing?
Many online lenders skip inspections and appraisals entirely, relying on the vehicle identification number and your loan history. Banks and credit unions are more likely to require an inspection or appraisal, especially for older cars or if you're refinancing a large amount. Ask each lender what they require before you explore.
How much money can I actually save by refinancing?
Savings depend on your current rate, the new rate, how much you owe, and how long you keep the car. A rough example: if you owe $15,000 at 8% with 48 months left, and you refinance to 5%, you'd save roughly $1,200 in interest over the remaining term. Use an online calculator with your actual numbers to see your potential savings.
