Refinancing replaces your current car loan with a new one, usually at a different interest rate
When you refinance a car loan, you take out a new loan from a different lender to pay off what you still owe on your current loan. The new lender pays your old lender in full, and you start making payments to the new lender instead. The main reason people refinance is to get a lower interest rate, which means smaller monthly payments or paying off the car faster.
The rate you receive depends on your credit score, the age and mileage of the car, how much you still owe, and current market rates. Someone with a credit score above 750 might receive a rate around 4–6%, while someone with a score between 600–650 might see rates between 10–15%. These ranges shift as the Federal Reserve adjusts its benchmark rate, which affects what banks charge across the board.
Refinancing is not automatic — you have to seek it out. Your current lender will not call you to suggest it. You contact new lenders (banks, credit unions, online lenders) directly, provide information about your car and loan, and they tell you what rate they would offer. If you like the offer, you move forward; if not, you stay with your current loan.
Key Takeaways
- Refinancing makes sense when the new interest rate is at least 1–2 percentage points lower than your current rate, because lenders charge fees that eat into your savings.
- Your credit score, the car's age and mileage, and how much you still owe all affect the rate a new lender will offer you.
- The refinancing process takes one to two weeks from process to funding, and your car title transfers to the new lender during that time.
- Refinancing resets your loan term, so you might pay the same amount per month but over a longer period, which costs more in total interest.
When refinancing saves you money versus when it costs you
Refinancing saves money only if the new rate is meaningfully lower than your current rate. If you are paying 9% and refinance to 7%, you save. If you are paying 5% and refinance to 4.5%, the savings are usually too small to cover the costs involved.
Those costs are real. Most lenders charge an origination fee (typically 0.5–2% of the loan amount), and some charge process or processing fees. A few states also charge a title transfer fee. On a $15,000 loan with a 1.5% origination fee, you would pay $225 upfront. You also lose any interest you had already paid on your old loan — that money does not transfer or refund.
The math works like this: calculate how much you would save per month with the new rate, multiply that by how many months remain on the new loan, then subtract the fees. If the result is positive and meaningful (usually at least $500), refinancing is worth considering. If it is under $300, the hassle and risk usually outweigh the benefit.
How your credit score affects the rate you receive
Lenders use your credit score to decide how risky you are as a borrower. A higher score means you have a history of paying bills on time, so lenders offer lower rates. A lower score means more risk, so rates are higher.
The ranges vary by lender, but generally: a score of 750 or above typically qualifies for rates in the 4–6% range; 700–749 usually sees 6–8%; 650–699 often gets 8–11%; and below 650 may face 12% or higher. These are not fixed — the same score might receive different offers from different lenders, and rates change daily based on market conditions.
If your credit score has improved since you took out your original loan, refinancing becomes more attractive. If it has dropped, you might not receive a better rate at all, and refinancing would waste time and money.

The car's age, mileage, and loan balance all matter
Lenders care about the car itself because they want to know what it is worth. If you owe $12,000 on a car worth $10,000, you are "underwater" — you owe more than the car is worth. Most lenders will not refinance underwater loans, or will only do so at a higher rate because the risk is greater.
Cars lose value as they age and accumulate miles. A car with 40,000 miles is worth more than the same model with 100,000 miles. Most lenders have cutoffs — some will not refinance cars older than 10 years, or with more than 150,000 miles. A few will go higher, but rates rise as the car gets older.
The amount you still owe also matters. Lenders prefer larger loans because the origination fee generates more revenue. Some lenders have minimum loan amounts of $5,000 or $7,500, so if you only owe $3,000, you cannot refinance with them. Smaller loans are harder to place, so you may have fewer options.
How long the refinancing process takes and what happens to your car
From the moment you submit an process to the moment the new lender funds the loan and pays off your old one usually takes 7–14 days. The lender will order a vehicle inspection (sometimes done at a dealership or inspection center, sometimes waived if the car is newer), verify your information, and prepare the paperwork.
During this time, your car's title is in transition. The old lender holds it until the new lender pays them off, then the new lender takes possession of the title. You can still drive the car — nothing changes about your use of it. But you cannot sell it or trade it in until the title transfer is complete.
You will need to provide the new lender with your current loan documents, proof of insurance, and the vehicle identification number (VIN). Some lenders ask for recent pay stubs or bank statements to verify income. Have these ready before you explore so the process moves faster.
Refinancing to a longer loan term can lower your payment but cost more overall
When you refinance, you do not have to keep the same loan term. If your original loan had 3 years left and you refinance, you could choose a new 3-year term, a 4-year term, or even a 5-year term. A longer term spreads the payments over more months, so each payment is smaller.
But spreading payments over more time means you pay more interest overall. If you refinance $10,000 at 6% over 3 years, you pay roughly $955 in interest. If you refinance the same amount at the same rate over 5 years, you pay roughly $1,600 in interest. The monthly payment drops, but the total cost rises.
This is a real trade-off. If your budget is tight and you need the lower monthly payment, extending the term might be necessary. But if you can afford the same payment as before, keeping the original term or shortening it saves you money in the long run.
Where to get refinancing quotes and what to compare
You can refinance through banks, credit unions, or online lenders. Credit unions often offer competitive rates to their members, so if you belong to one, start there. Banks offer refinancing but may have stricter requirements. Online lenders are often faster and may accept lower credit scores, but rates are sometimes higher.
When you contact lenders, ask for the interest rate, any fees (origination, process, processing, title transfer), the loan term options, and the estimated monthly payment. Request this in writing or take notes — verbal quotes can change. Compare at least three offers side by side.
Be aware that when you explore, the lender will pull your credit report, which causes a small temporary dip in your score. Multiple pulls within 14 days usually count as one inquiry, so explore to several lenders within a short window if you want to compare. Waiting weeks between applications means each one hits your score separately.
Reasons refinancing might not work for you
If you are underwater on your loan (owe more than the car is worth), most lenders will decline you. Some will refinance if you have a co-signer or if you pay down the balance first, but options are limited. If your car is very old or has very high mileage, lenders may refuse or offer only high rates that do not save you money.
If you are near the end of your loan — say, 6 months or less remaining — refinancing rarely makes sense. The fees and the short payoff window mean you will not recover the costs. If your credit score has dropped since you took out the original loan, you might not receive a better rate, making refinancing pointless.
If you are planning to sell or trade in the car soon, refinancing is usually a waste of time. The new lender holds the title until the loan is paid off, so you cannot complete a sale or trade until refinancing is done. By then, you may have already moved on.
Frequently Asked Questions
Will refinancing hurt my credit score?
The credit inquiry from explore will cause a small, temporary dip — usually 5–10 points. This recovers within a few months. If you make on-time payments on the new loan, your score will likely improve over time. The risk is if you miss payments on the new loan; that will damage your score much more than the initial inquiry.
Can I refinance if I still owe money on my car?
Yes, that is the whole point of refinancing. You refinance the amount you still owe. If you owe $8,000 on a car worth $10,000, most lenders will refinance the $8,000. If you owe $10,000 on a car worth $8,000, you are underwater and most lenders will decline.
What happens if I refinance and then want to pay off the loan early?
Most car loans have no prepayment penalty, meaning you can pay off the balance whenever you want without extra fees. Check the loan documents before you sign to confirm. Paying off early saves you interest, so if you have the money, it is usually worth doing.
Do I need to tell my current lender I am refinancing?
No. The new lender handles everything — they pay off the old loan directly. You do not need permission from your current lender. You will receive a payoff letter from them once the new lender has paid them in full, confirming the old loan is closed.
Can I refinance with the same lender I currently use?
Yes, though it is less common. Some banks and credit unions allow you to refinance with them. The advantage is they already have your information on file, which can speed up the process. The disadvantage is you may not receive their best rate if you are already a customer — new customers sometimes get promotional rates.
