Car Loans: What You’ll Really Pay and How to Pay Less

Most car buyers ask what the monthly payment is. The better question is what the whole loan costs.

A car loan is money you borrow to buy a vehicle and pay back in fixed monthly payments, usually over three to seven years. Your rate depends mostly on your credit score, the loan length and whether the car is new or used. The loan length matters more than people expect: at 8% APR, borrowing $30,000 over 84 months costs about $9,300 in interest, and over 48 months it costs about $5,200. This guide shows how car loan rates work, what each option really costs, and how to keep more of that interest in your own pocket.

What a car loan is, and the two ways to get one

A car loan is usually a secured installment loan: the lender holds a lien on the car’s title until you pay it off, and it can repossess the car if you stop paying. Because the car backs the loan, secured auto loans usually carry lower rates than unsecured borrowing.

You can get that financing in two places:

• Direct financing. You borrow from a bank, credit union or online lender before you shop, then show up at the dealer with a preapproval, which is about as close as car shopping gets to paying cash.
• Dealer financing. The dealer sends your application to lenders it works with and arranges the loan for you. It’s convenient, and it sometimes comes with manufacturer promotions, but the dealer can add to the rate the lender offered (more on that below).

There’s also a third route: an unsecured personal loan used to buy a car. No lien goes on the title, and the money lands in your bank account, so you can buy from a dealer or a private seller. The trade-off is usually a higher rate. We cover it in its own section further down.

Car loan rates: what moves the number you’re offered

Your car loan rate is set by the lender, based mainly on your credit score, the loan term, the car’s age and how much you put down. On a $20,000 loan over 60 months, the gap between a 7% and a 21% rate is about $8,700 in interest.

Here’s that same $20,000, five-year loan at four different rates:

Illustrative rates, not quotes or offers. Your actual rate depends on your credit profile and the lender.

Notice the monthly payment only moves by about $145 from the top row to the bottom one. The total moves by about $8,700. That’s why a lender, or a dealer, would much rather talk about the payment.

What pushes your rate up or down:

• Credit score. The biggest single factor. Borrowers with strong credit get the lowest rates, and each step down the score ladder usually costs you.
• Loan term. Longer loans often carry higher rates as well as more months of interest, a double hit.
• New or used. Used car loan rates usually run higher than new car rates for the same borrower, and older, higher-mileage cars can cost more still.
• Down payment. Putting more down means the lender has less at risk, which can improve your rate and keeps you from owing more than the car is worth.
• Debt-to-income ratio. Lenders compare your monthly debt payments with your income. Less existing debt makes you a safer bet.
• Where you borrow. Credit unions, banks, online lenders and dealers price loans differently, so the same borrower can get different offers on the same day.

The term trap: why 72- and 84-month car loans cost so much

Stretching a car loan from 48 to 84 months cuts the monthly payment by about $265 on a $30,000 loan at 8%, and it adds about $4,100 in interest. The payment feels better every month, and the total gets worse every month.

This example even assumes the rate stays at 8% for every term, and in real life longer loans often come with a higher rate, which makes the right side of that chart taller still.

There’s a second cost that doesn’t show up in the table. Cars lose value fastest in their first few years, while a long loan pays down the balance slowly. That combination can leave you “upside down,” owing more than the car is worth. The Consumer Financial Protection Bureau (CFPB) has warned that longer auto loans cost more over time, and that a loan can outlast the car, leaving you still paying after you’ve stopped driving it. If you trade in an upside-down car, the leftover balance often gets rolled into the next loan, and now you’re paying interest on a car you no longer own.

I’ll admit a lower payment is nice to look at on a budget spreadsheet. It’s not $4,100 nice. If the only way a car fits your budget is at 84 months, the car is telling you something.

Car loans with bad credit: what’s realistic

You can usually get a car loan with bad credit, but you’ll pay a higher rate, often in the double digits, and you may need a bigger down payment. On a $20,000 loan over five years, a 21% rate costs about $8,700 more in interest than a 7% rate.

A few moves that make a real difference when your score is low:

1. Check your credit reports first. Errors happen. You can get your reports free at AnnualCreditReport.com and dispute anything that’s wrong before a lender sees it.
2. Put more down. Every dollar you don’t borrow is a dollar you don’t pay 15% or 21% on, and it lowers the lender’s risk.
3. Pick a cheaper car. Keeping the loan small matters most at high rates. At 21%, $12,000 borrowed instead of $20,000 saves you about $5,000 in interest over five years.
4. Keep the term short. A higher rate over a longer term compounds the damage. Aim for 48 months or less if the payment works.
5. Consider a cosigner. A cosigner with stronger credit can get you a lower rate, but they’re on the hook for every payment you miss, and the loan shows up on their credit.
6. Plan to refinance. Twelve months of on-time payments can lift your score enough to refinance at a lower rate (see the refinancing section below).

Be careful with “buy here, pay here” lots, where the dealer is also the lender. They approve buyers other lenders won’t, but they often charge high rates on older cars, and some may not report your on-time payments to the credit bureaus, so the loan may not help rebuild your credit. Ask before you sign. Our bad credit loans guide covers what else is realistic with a lower score.

Your car financing options side by side

The cheapest way to finance a car is usually a direct auto loan from a bank or credit union. Here’s how the main options compare.

General comparison. Actual rates, fees and terms depend on your credit profile, the lender and the vehicle.

How to get a car loan, step by step

1. Set a total budget, not a payment. Decide the most you’ll spend on the car, including taxes and fees, and the shortest term you can manage. A common rule of thumb is 20% down, four years or less, and total car costs under 10% of your gross income.
2. Check your credit. Know your score and fix report errors before you apply.
3. Get preapproved. Apply for an auto loan with a bank, credit union or online lender so you walk in with an offer the dealer has to beat.
4. Shop within a short window. Credit scoring models count multiple auto loan inquiries in a short period (14 to 45 days, depending on the model) as a single inquiry, so compare offers quickly.
5. Negotiate the car’s price first. Agree on the out-the-door price before you talk about financing or your trade-in. Mixing all three makes it easy to lose track of the numbers.
6. Let the dealer try to beat your rate. If they offer a lower APR in writing, good. If not, use your preapproval.
7. Read the contract before you sign. Check the APR, the amount financed, the term, the total of payments and any add-ons. Federal law requires the creditor, which is often the dealer, to disclose the APR, finance charge, amount financed, total of payments and payment schedule before you sign.

The driveway math: two ways to buy a car

Financing a $35,000 SUV for 84 months at 9% costs about $12,300 in interest. Buying a $15,000 used car on a 36-month loan at the same rate and investing the difference could leave you with about $34,000 after seven years.

Picture two neighbors with the same commute and the same 9% rate.

Neighbor one finances a new $35,000 SUV over 84 months. The payment is about $563 a month. Over seven years they pay about $47,300, which means roughly $12,300 went to interest. At the end, they own a seven-year-old SUV.

Neighbor two buys a reliable used car for $15,000, financed over 36 months. That payment is about $477 a month, and the loan costs about $2,200 in interest. They invest the $86 a month they’re saving compared with neighbor one. When the loan is paid off after three years, they keep writing the same $563 check every month, just to an index fund instead of a lender.

Assume a modest 5% yearly return, which is not guaranteed and not a promise. After seven years, neighbor two has about $34,000 invested and a paid-off car. Neighbor one has a finished loan.

The SUV is nicer to sit in. I doubt it’s $34,000 nicer.

You don’t have to drive a beater to use this. The lesson is about the two levers you control: how much you borrow and how long you take to pay it back. Shrink either one and the savings add up faster than most people expect.

Illustrative example. Loan figures assume a fixed 9% APR. The investment figure assumes $86 a month for 36 months, then $563 a month for 48 months, at a 5% annual return compounded monthly. Returns are not guaranteed.

Using a personal loan to buy a car

You can use a personal loan to buy a car. Because it’s usually unsecured, it typically costs more than a secured auto loan: $15,000 over four years at 15% costs about $2,100 more in interest than the same loan at 9%.

So why would anyone choose it? A personal loan makes sense in a few situations:

• You’re buying from a private seller and want cash in hand instead of arranging a private-party auto loan.
• The car is old or high mileage and doesn’t meet an auto lender’s age or mileage limits.
• You want a clean title from day one, with no lien and no lender’s name on the paperwork.
• You’re covering part of the price, such as a down payment or the gap on an inexpensive car, and the amount is small.

One more difference. The new federal car loan interest deduction (see below) only applies to loans secured by a first lien on the vehicle, so interest on an unsecured personal loan doesn’t qualify. Our secured vs. unsecured loans guide explains the trade-offs in more detail.

Illustrative rates, not quotes or offers. Your actual rate depends on your credit profile and the lender.

Used car and private-party loans

Used car loans work like new car loans, but rates usually run a bit higher, and some lenders cap the car’s age or mileage. The upside is that the car costs less to begin with, so you borrow less, and a smaller loan is the easiest money you’ll ever save.

Buying from a private seller takes a few extra steps. Some banks, credit unions and online lenders offer private-party auto loans. The lender usually pays the seller directly, checks the title and handles the lien. If you use a personal loan instead, you pay the seller yourself, so make sure the seller’s name is on the title and there’s no existing lien before money changes hands. A pre-purchase inspection by an independent mechanic costs far less than a surprise transmission.

Refinancing a car loan

Refinancing replaces your current car loan with a new one, ideally at a lower rate. Moving a $22,000 balance with 54 months left from 14% to 9% saves about $54 a month and roughly $2,900 in total interest.

Refinancing is worth checking when:

• your credit score has improved since you bought the car
• rates have dropped since you took the loan
• you took dealer financing without comparing offers

Keep the remaining term the same or shorter. If you stretch it longer, a lower payment can still mean more total interest. Check for a prepayment penalty on your current loan and any fees on the new one, and remember that very old or high-mileage cars can be harder to refinance.

Illustrative example assuming fixed rates and the same 54-month remaining term. Not a quote or offer.

Lease buyout loans

A lease buyout loan lets you buy the car you’ve been leasing at the end of the lease, for the buyout price in your contract. It’s worth doing when that price is below what similar cars sell for, or when you’ve gone over your mileage limit and would owe charges anyway. Compare the buyout price with the car’s market value, and shop the loan the same way you would for any used car.

The car loan interest tax deduction

Under the federal tax law passed in 2025, you may be able to deduct up to $10,000 a year of interest on a loan for a new car, for tax years 2025 through 2028. The rules are specific:

• the vehicle must be new, bought for personal use, weigh under 14,000 pounds (gross vehicle weight rating) and have its final assembly in the United States; cars, SUVs, vans, pickups and motorcycles can qualify
• the loan must be taken out after December 31, 2024 and secured by a first lien on the vehicle, so unsecured personal loans and leases don’t count
• the deduction shrinks, and can phase out entirely, above $100,000 of modified adjusted gross income ($200,000 for married couples filing jointly)
• you can take it whether or not you itemize, and you’ll need to report the vehicle’s VIN on your return
• a refinanced loan keeps qualifying only up to the balance of the original qualifying loan

You can check where a car was assembled on its window sticker or with the NHTSA VIN decoder. Keep in mind the deduction reduces your taxable income, not your tax bill dollar for dollar, and it’s currently scheduled to end after 2028, while a seven-year loan taken out now would keep charging interest well past then. It’s a nice discount on interest. It’s not a reason to borrow more. Check with a tax professional about your own situation.

Dealer financing red flags

The most expensive part of a car deal is often the financing, not the car. A dealer markup of just 2 percentage points on a $30,000, 60-month loan costs you about $1,700.

Watch for these:

• Rate markup. When a dealer arranges your loan, the lender may give the dealer a rate, and the dealer may be able to add to it and keep part of the difference. Going from 7% to 9% on $30,000 over five years adds about $29 a month. A preapproval is your best defense.
• “What payment are you looking for?” Answering this first lets the deal be built around the payment by stretching the term or trimming your trade-in value. Talk about the total price.
• Add-ons packed into the loan. Extended warranties, GAP coverage, service contracts and similar products are optional. Some can be useful, but each one should be priced separately and you can say no. Anything rolled into the loan also collects interest.
• Deals that aren’t final. In a “spot delivery,” you drive home before the financing is approved. If the dealer later says the loan fell through, you may be pressured to sign a new contract at a higher rate. Ask whether the financing is final before you take the car, and get the answer in writing.
• Guaranteed approval, fees before funding. A lender offering “guaranteed approval” without looking at your finances, or asking for a fee before you get the loan, is a warning sign.

Markup example is illustrative, assuming fixed rates over 60 months.

How a car loan affects your credit score

A car loan causes a small, temporary dip when you apply and can help your credit over time if you pay on time. Here’s how it plays out:

• When you shop, each application usually triggers a hard inquiry, but scoring models treat several auto loan inquiries within a short window as one, so compare rates within a couple of weeks.
• Opening the loan lowers the average age of your accounts a little.
• On-time payments are reported to the credit bureaus and help build your history. A single payment 30 or more days late can do real damage, and repossession stays on your reports for years.

Our guides to your credit score and improving your credit explain what moves it.

Is a car loan right for you?

A car loan makes sense when you need a car to get to work, can’t pay cash without draining your emergency fund, and can afford the payment on a term of about four to five years.

It’s probably a good fit if:

• the payment leaves room in your budget for insurance, fuel and repairs, which can add up to as much as the payment itself
• you’re borrowing for a reliable car that fits your needs, not the top trim level
• you can keep the term to 60 months or less
• you’ve compared at least one offer outside the dealership

It’s worth pausing if the only way to afford the car is a 72- or 84-month term, you’d be rolling negative equity from your current car into the new loan, or your rate is high enough that saving a few more months for a bigger down payment would change the math.

Here’s your homework. If you already have a car loan, dig out the paperwork and check two numbers: your APR and the months left. If your credit has improved or the rate looks high, a refinance quote costs you ten minutes. And the next time someone asks what monthly payment you’re comfortable with, answer with a question of your own: what’s the total price?

Frequently asked questions

What is a good interest rate for a car loan?

A good car loan rate is one at or below what lenders offer borrowers with your credit score for the same term and vehicle age. Rates change with the market, so compare at least two or three offers, including one from outside the dealership, within a short shopping window.

How long should a car loan be?

Most buyers are better off with a car loan of 60 months or less, and 48 months or less if the payment fits. Longer loans lower the payment but add interest: at 8% APR, $30,000 over 84 months costs about $4,100 more in interest than over 48 months.

Can I get a car loan with bad credit?

Yes, many lenders offer car loans to borrowers with bad credit, but the rate will be higher and a larger down payment may be required. Borrowing less, keeping the term short and refinancing after a year of on-time payments are the best ways to limit the cost.

Is it better to get financing from the dealer or a bank?

It’s usually best to get preapproved by a bank, credit union or online lender first, then let the dealer try to beat that rate. Dealer financing can include manufacturer promotions, but a dealer may also add a markup to the lender’s rate.

Can I use a personal loan to buy a car?

Yes. A personal loan puts cash in your account that you can use to buy a car from a dealer or a private seller, with no lien on the title. It usually costs more than a secured auto loan, and its interest doesn’t qualify for the federal car loan interest deduction.

How much should I put down on a car?

A common rule of thumb is 20% down on a new car and at least 10% on a used one. A bigger down payment lowers your loan amount, can improve your rate and helps keep you from owing more than the car is worth.

Does shopping for a car loan hurt my credit?

Only slightly, if you shop within a short window. Credit scoring models count multiple auto loan inquiries made within 14 to 45 days, depending on the model, as a single inquiry.

Is car loan interest tax deductible?

For tax years 2025 through 2028, you may deduct up to $10,000 a year of interest on a loan for a new, U.S.-assembled vehicle bought for personal use, if the loan is secured by a first lien on the car. The deduction phases out at higher incomes and doesn’t apply to used cars, leases or unsecured loans.
