New car, used car or refinance — compare auto loan options before you visit the dealership. Knowing your numbers first puts you in a stronger negotiating position.
- New, used and refinance options in one place
- Fixed monthly payments and clear terms
- Get pre-approved before you shop
Know your numbers first
Dealer financing can be convenient, but it isn't the only option. A little preparation can help you avoid paying for the wrong loan.
Set a total budget
Decide what you can afford each month and overall — including insurance, fuel, maintenance and registration.
Get pre-approved
A pre-approval gives you a rate and amount to compare against dealer financing — without committing to buy.
Negotiate the price, not just the payment
A long term can make any car look affordable. Focus on the out-the-door price and total interest.
How auto loans work
An auto loan is a secured installment loan: the vehicle serves as collateral, and the lender may repossess it if you stop making payments. You typically pay a fixed interest rate over a set term, usually 24 to 84 months. The longer the term, the lower the monthly payment — but the more interest you pay overall, and the longer you stay upside down on the car.
Your rate depends on the lender, your credit history, the loan term, the vehicle's age and value, your down payment and the amount financed. Comparing several offers helps you see which combination of rate and term actually costs less.
New, used or refinance?
| Loan type | Best suited to | Watch out for |
|---|---|---|
| New vehicle | Buying from a dealer, often with manufacturer incentives | Long terms, add-ons and depreciation in the first years |
| Used vehicle | Lower purchase price, certified pre-owned or private sale | Higher rates, mileage limits and inspection requirements |
| Refinance | Replacing an existing loan with a lower rate or better term | Fees, prepayment penalties and the remaining balance |
Compare more than the interest rate
- APR: includes interest and certain fees, making it a better apples-to-apples comparison.
- Term length: shorter terms usually cost less overall but have higher monthly payments.
- Down payment: a larger down payment reduces the amount financed and can improve your rate.
- Fees: look for origination, documentation, title and prepayment fees.
- Total cost: multiply the monthly payment by the number of months, then add your down payment.
Rule of thumb: many advisers suggest keeping total vehicle costs — loan payment plus insurance — within about 15–20% of your take-home pay. Your own budget should account for fuel, maintenance and emergencies too.
Dealer financing vs. pre-approval
Dealers often work with multiple lenders and can be convenient, especially if you want to drive away the same day. But it's worth getting a pre-approval from a bank, credit union or online lender first. You'll know your rate and maximum amount, and you can use that as a benchmark when the finance office presents its offer.
If you let the dealer arrange financing, ask for the APR, term, amount financed, total of payments and any add-ons in writing. You are not obligated to accept extras such as extended warranties, GAP insurance or paint protection.
Avoiding common auto loan mistakes
- Shopping by monthly payment alone and stretching the term to fit.
- Rolling negative equity from an old loan into a new one without understanding the cost.
- Skipping a pre-purchase inspection on a used vehicle.
- Forgetting that a shorter loan term can save significant interest.
- Signing before comparing at least a couple of offers.

Common car loan questions
Should I get pre-approved before car shopping?
It's generally a good idea. A pre-approval tells you how much you can borrow and at what rate, so you can shop within budget and compare the dealer's offer. Ask whether the lender performs a hard credit inquiry and how long the pre-approval lasts.
What is a good auto loan term?
Shorter terms cost less in total interest but have higher monthly payments. Many buyers choose 36 to 60 months. Longer terms can make an expensive car look affordable, but you may owe more than the car is worth for longer. Choose the shortest term your budget can comfortably handle.
Can I refinance a car loan?
Yes, refinancing replaces your current loan with a new one, ideally at a lower rate or with better terms. It can make sense if your credit has improved or rates have fallen. Compare the new loan's fees and total cost against your current balance before switching.
Does a car loan require a down payment?
Not always, but a down payment reduces the amount you finance and may improve your approval odds and rate. It also helps prevent negative equity. Some lenders require a minimum down payment, especially for used vehicles or lower credit scores.
