How to Refinance a Car Loan in 7 Steps

To refinance a car loan: check your credit, confirm your car and balance meet lender minimums, gather proof of income and insurance, request a 10-day payoff quote from your current lender, compare offers inside a two-week window, and let the new lender pay off the old loan. Most refinances close in one to two weeks.

That is the whole map. The details are where refinances go sideways — a term extension that quietly costs more than the rate cut saves, a missed payment on a loan you thought was closed, a GAP policy that vanished with the old loan. I’ve refinanced three of my own cars and completed two lease buyouts, and the process rewards preparation far more than it rewards speed. Here is each step in order, with the numbers and deadlines that matter.

Step 1: Run the numbers on your current loan

Pull up your loan statement and find three things: your current APR, your remaining balance, and how many months you have left. Refinancing only works when the new rate beats the old one by enough to cover the small costs and the paperwork hassle — and the way that usually happens is that your credit improved since you signed, or you overpaid at the dealership in the first place.

Here is what a realistic move looks like. Say you financed a used car two years ago at near-prime pricing and your score has since climbed into prime territory. Using Experian’s Q1 2026 average APRs for those tiers on a $20,000 balance with 48 months left:

That is $51 a month back and about $2,463 in interest avoided — without adding a single month to the loan. Your numbers will differ, so run your own balance and rate through our auto refinance calculator before you apply. If the math shows savings of only a few dollars a month, stop here; refinancing is not free money, and a marginal rate cut rarely justifies the effort.

Step 2: Check your credit score

Your credit tier sets your price, so know it before any lender does. Experian puts the threshold for the best terms at a FICO score of 670 or higher, but the more useful view is the full pricing ladder. These are the average APRs lenders charged in Q1 2026, per Experian’s credit-tier data:

Notice the jumps between tiers. Crossing from near prime into prime is worth more than five percentage points on a used-car loan — that is the single biggest lever in this entire process. If you are within 10 or 20 points of the next tier and a few months of on-time payments would get you there, waiting can be worth real money. While you are at it, pull your free credit reports and dispute any errors; a wrongly reported late payment can cost you a tier.

Step 3: Confirm your car and loan qualify

Lenders refinance the car as much as the borrower, and each one publishes its own box the deal must fit inside. Capital One, for example, requires a loan between $7,500 and $75,000 on a vehicle 10 years old or newer, and will not touch commercial vehicles, salvage titles, or lease buyouts. Specialty refinance lenders are often looser: RefiJet’s published guidance describes typical industry limits of 100,000 to 150,000 miles depending on the lender, minimum balances often around $5,000, and roughly 24 months remaining on the term.

Three quick self-checks before you apply anywhere: your loan balance clears the lender’s minimum, your car is under the age and mileage caps, and your current loan is in good standing. If your odometer is the problem, limits vary enough between lenders that it pays to target the right ones — our guide to refinancing a high-mileage car covers who accepts what. And if you are trying to keep a leased car rather than refinance a loan, that is a different transaction with its own process — see our lease buyout guide.

Step 4: Gather your documents

Every lender asks for roughly the same stack. Assembling it before you apply is the cheapest way to shave days off the timeline, because most funding delays are really document delays. Based on Experian’s checklist and RefiJet’s requirements list, plan on:

• Driver’s license (a valid government-issued ID)
• Proof of income — typically pay stubs from the last two pay periods, or tax returns if self-employed
• Proof of residence — a utility bill or mortgage statement
• Proof of active auto insurance
• Vehicle details: VIN, year, make, model, and current mileage (some lenders want an odometer photo)
• Current loan details: lender name, account number, balance, rate, and payment
• A 10-day payoff statement from your current lender (next step)

Step 5: Get your 10-day payoff quote

Having refinanced three of my own cars, I can tell you the step people skip is this one. Your loan balance on the app is not your payoff amount — interest accrues daily, so the number the new lender must send is the balance plus interest through the payoff date. That exact figure comes from a 10-day payoff quote: a statement from your current lender, valid for 10 days, showing precisely what it takes to close the loan. Request it by phone or through your lender’s online portal; it is free.

In my own refinances this was the least painful step of the whole process: one phone call to the current lender, quote in hand almost immediately, no surprises against what the app showed. Don’t let the easiest step be the one you skip.

Time the request so the quote is fresh when your new loan funds. A stale quote means the new lender underpays or overpays the old one by a few days of interest — a small mess, but an avoidable one.

Step 6: Compare offers inside the rate-shopping window

Do not take the first approval. Rate spreads between lenders on the same borrower are real, and the credit-scoring system is built to let you shop: FICO scores count multiple auto loan inquiries within a shopping window as a single inquiry. Newer FICO versions use a 45-day window; older versions still in use at some lenders use 14 days. The practical rule: submit every application within the same two weeks and your score takes roughly one inquiry’s worth of impact, not five.

Many lenders will also prequalify you with a soft pull first — a rate estimate with no score impact at all — and only run the hard inquiry when you formally apply. Start there. When offers arrive, compare APR (not the monthly payment), the term in months, and any fees, holding the term equal to what remains on your current loan so the comparison is honest. Our rundown of the best auto refinance companies breaks down where each lender is strong if you want a starting list.

Step 7: Close the new loan and confirm the old one is paid

Once you accept an offer, the new lender handles the heavy lifting: it pays off your old loan directly using the payoff quote and files the paperwork to put itself on the title as lienholder. Your two jobs at this stage are less glamorous but critical.

First, keep making payments on the old loan until you have written confirmation it is paid off. Payoffs in transit can straddle a due date, and a late mark on a loan you were days from closing is a painful own goal. If you overpay in the transition, the old lender refunds the difference.

Second, expect some small closing costs and know where they come from. Per SoFi’s breakdown, the usual suspects are a state title-transfer fee, possible re-registration depending on your state, processing fees at some lenders, and — worth checking before you ever apply — an early payoff penalty on your existing loan, which some contracts carry. None of these are typically large, but read the fine print so nothing surprises you. One more carryover item: GAP coverage does not transfer to the new loan. The old policy dies with the old loan; if you paid for it upfront you can request a prorated refund, and if you still owe more than the car is worth, price a new policy for the refinanced loan.

What lenders check when you apply

Underwriting a refinance is a four-part question, and knowing the parts tells you where an application can wobble:

• Your credit. Score and history set the rate tier. Published minimums, where they exist at all, tend to sit around 600— but a minimum is an admission ticket, not a good price.
• Your income and debts. Lenders verify income and prefer a debt-to-income ratio under roughly 35%, per RefiJet’s guidance. A raise since your original loan helps; new debts hurt.
• The car. It is the collateral, so age, mileage, condition, and title status all matter — and so does how the balance compares to the car’s value. Owing far more than the car is worth makes approval harder.
• The existing loan. Good standing and a clean recent payment history on the current loan are close to non-negotiable.

How long refinancing takes

Faster than most people expect. The application itself takes minutes to a few hours of gathering and uploading, and Chase pegs the entire process at one to two weeks, stretching longer mainly when documents trickle in slowly. The title work — moving the lien from the old lender to the new one — continues in the background for weeks after funding, but that is the lenders’ problem, not yours.

The bigger timing question is how soon after buying the car you can refinance at all. Experian notes the title transfer from your purchase can take 60 to 90 days, some lenders will not refinance a loan younger than six months, and waiting about six months generally means more lender options plus time for your score to recover from the purchase inquiry. The exception worth acting on early: if your credit has jumped a full tier since you signed, or your original dealer-arranged rate was clearly above your tier’s average, the savings from moving sooner can outweigh the wait.

Mistakes that erase your savings

Chasing a payment instead of a rate. The seductive version of refinancing is stretching the term. Take the Step 1 example: refinancing that $20,000 balance at 8.77% over 72 months instead of 48 drops the payment to $358 — $189 a month of relief — but you would pay about $2,008 more total interest than the same-term refinance. A longer term is sometimes the right call for genuine cash-flow strain; just make it knowingly, with the total-interest number in front of you.

Rate shopping in slow motion. One application this month, another next month, a third in the fall — each lands as a separate hard inquiry. Compress your shopping into a single two-week burst and FICO treats it as one.

Refinancing while your score is still deep subprime. Honesty matters here: if your score is in the low 500s or below, the average used-car APR in your tier is 19% to 22% per Experian’s Q1 2026 data. Swapping one very high rate for another very high rate rarely moves the needle, and each attempt costs an inquiry. Six to twelve months of clean payments that lift you a tier will do more than any lender can at your current score.

Going silent on the old loan too early. The refinance is not done when you sign — it is done when the old lender confirms a zero balance. Keep autopay on until then.

Forgetting the GAP policy. It does not follow you to the new loan, and the refund on an upfront-paid policy is not automatic — you have to ask for it.

Refinancing is one of the few personal-finance moves where an hour of paperwork can return a four-figure sum, and having done it three times myself, the pattern is consistent: the people who save real money are the ones who ran the numbers first and shopped inside the window.
