Your car loan is probably one of the bigger monthly bills in your life, right after rent or a mortgage. If you took it out a year or two ago when rates were high, or before your credit score climbed, you may be paying more than you need to. Refinancing can trim your interest rate, drop your payment, or shorten the loan so you own the car sooner.
This guide walks through when refinancing makes sense, how much it can save, what lenders look at, and how to shop rates without hurting your credit. By the end, you will know whether a refi is worth the paperwork or whether you should just keep paying on your current loan.
When Refinancing Your Auto Loan Makes Sense
Refinancing works best in three situations. The first is when interest rates have dropped since you first took out the loan. Even a one percentage point cut can save hundreds of dollars over a few years. The second is when your credit score has gone up. If you were in the 600s and you are now in the 700s, you can likely qualify for a much lower rate.
The third is when your life has changed. Maybe you want a lower payment because cash is tight, or you want to pay off the car faster because you got a raise. Refinancing lets you reset the loan term, so you can stretch or shrink the payoff timeline. It may also let you drop a co-signer if you no longer need one. APRs vary by lender and credit profile.
How Much You Can Actually Save
The savings depend on three things: your current rate, your new rate, and how much you still owe. Say you have $18,000 left on a 60-month loan at 9 percent APR. Your monthly payment is about $374. If you refinance at 6 percent for the remaining 48 months, the new payment drops to around $423 on a 36-month term, or $331 if you keep a 60-month term.
Over the life of the loan, that rate cut can save $1,500 or more in interest. Most lenders offer free rate-check tools that show your potential savings before you commit. Use those before you apply anywhere.
Credit Score Requirements and Loan-to-Value
Most auto refinance lenders want a FICO of 660 or higher for their best rates. Scores from 600 to 659 can still get approved, but the rates are much higher. Below 580, options get thin and expensive.
Lenders also care about your loan-to-value ratio, or LTV. That is how much you owe divided by the car's current value. If your LTV is above 125 percent, meaning you owe significantly more than the car is worth, refinancing gets harder. Most lenders cap LTV at 125 to 140 percent. You can check your car's value on Kelley Blue Book or Edmunds before you apply.
Age and mileage matter too. Many lenders will not refinance cars older than 10 years or with more than 125,000 miles. Some are looser, some are stricter.
Best Refinance Lender for Rate Shopping: myAutoloan
myAutoloan is a marketplace that lets you compare up to four refinance offers with a single application. You fill out one form, and partnering lenders send back rates within minutes. This cuts the annoying part of auto refi, which is entering your info on five different lender sites.
It works for credit profiles from roughly 575 and up. Rates start in the mid-single digits for prime borrowers and climb from there. The credit pull for pre-qualification is a soft inquiry, so your score does not take a hit just for looking. Only when you pick a lender and formally apply does a hard pull happen. This setup matches the FICO rate-shopping window, which we will cover next.

The 14-Day Rate Shopping Window
Here is the piece most people miss. FICO lets you shop for auto loans within a 14 to 45 day window, and all the hard pulls count as just one inquiry on your score. This means you can apply at five lenders in one weekend and only see a single ding on your credit report, not five.
Use this window wisely. Do your homework, line up three to five lenders you want to try, and apply within a tight window. You can compare real offers side by side without wrecking your score. Start with soft-pull pre-qualification, then hard-pull the top two or three.
Best for Fair-to-Average Credit: MoneyLion
If your credit score sits below 660, or you have had rough months recently, mainstream refinance lenders may pass. MoneyLion offers personal loans and credit-builder products that can work alongside your auto loan refinance journey.
MoneyLion does not do direct auto refi, but their Credit Builder Plus loan can help raise your score in 6 to 12 months, which then opens up better auto refi offers. Think of it as a two-step play. Build your credit first, then refinance the car. For someone with a FICO in the 550 to 620 range, this sequence often yields a much bigger lifetime savings than rushing into a high-rate refi today. Terms apply.
Documents You Will Need
Most lenders ask for the same short list. Have your driver's license, pay stubs from the last 30 days, proof of residence like a utility bill, and your current loan payoff statement. You can get the payoff amount by logging into your current lender's website.
You also need the car's VIN, current mileage, and registration. Proof of insurance is required to close the loan. Gathering all this before you apply speeds things up. Online lenders can sometimes close in 2 to 5 business days once documents are uploaded.
Common Mistakes to Avoid
The biggest mistake is stretching the term too long. If you refinance a loan with 36 months left into a new 60-month loan, your payment drops but you pay more interest overall. Look at total cost, not just monthly payment.
Another pitfall is refinancing when you are underwater, meaning you owe more than the car is worth. This can work if your new rate is much lower, but most lenders will not touch a loan with LTV above 140 percent. Waiting a few months until your balance drops below the car's value can save you the headache.
Finally, do not forget prepayment penalties on your current loan. Most car loans do not have them, but a small number do. Check your contract before you start the refi.
Frequently Asked Questions
Will auto loan refinancing hurt my credit score?
You may see a small drop of 5 to 10 points from the hard inquiry and the new account. Shopping within a 14 to 45 day window counts multiple pulls as one inquiry. Most borrowers recover the points within a few months of on-time payments.
How soon after buying a car can I refinance?
Most lenders want to see at least 60 to 90 days of payment history on your current loan before they consider a refinance. Some require 6 months. Waiting also gives your title time to transfer fully, which some lenders require before they will fund a refi.
Can I refinance if I owe more than my car is worth?
Sometimes. Lenders usually cap loan-to-value at 125 to 140 percent. If your LTV is higher, you may need to pay down the balance before you qualify. Adding cash to the deal or waiting a few months to lower the balance can help.
What credit score gets the best auto refinance rates?
Borrowers with FICO scores of 720 or higher get the lowest rates, often starting in the mid-single digits. Scores of 660 to 719 can still get competitive offers. Below 660, rates rise significantly, and you may save more by building credit first with tools like MoneyLion before refinancing. APRs vary.
