What a preapproved car loan is
A preapproval is a lender's conditional promise to loan you a specific amount of money for a car purchase, based on information you've already provided. It is not a may provide — the lender can still say no when you actually buy the car — but it tells you roughly how much you can borrow and at what interest rate, before you walk into a dealership.
The key word is "conditional." The lender has checked your credit report and income, but they haven't seen the actual car you plan to buy, haven't verified your employment by calling your employer, and haven't run a final background check. A preapproval is good for a set period — usually 30 to 90 days — and only for the amount stated in the letter.
Preapprovals come from banks, credit unions, and online lenders. They do not come from the dealership itself, though a dealership can help you find lenders who offer them. Getting preapproved before you shop gives you negotiating power: you know your budget, you can walk away from a bad deal, and you're not dependent on the dealership's financing.
Key Takeaways
- A preapproval is a lender's conditional offer to loan you money at a specific rate, based on your credit and income, and is valid for 30 to 90 days.
- Preapprovals do not lock in your rate or may provide final approval — the lender can still deny you or change the terms when you buy the actual car.
- You can get preapproved from a bank, credit union, or online lender without visiting a dealership, and the process usually takes one to three business days.
- Shopping for preapprovals from multiple lenders within two weeks does not significantly harm your credit score, because credit bureaus treat multiple auto loan inquiries as a single search.
- A preapproval letter gives you a negotiating advantage at the dealership because you know your budget and can decline dealer financing if it's worse than your preapproved terms.
How to get preapproved before you shop
Start by contacting lenders directly — your bank, your credit union, or online lenders like LendingClub, Upstart, or Lightstream. You can also visit the websites of major banks and credit unions to find their auto loan pages. Each lender has an online form or phone line where you can request a preapproval.
You will need to provide your Social Security number, date of birth, current income, employment status, and the amount you want to borrow. The lender will pull your credit report and may ask for recent pay stubs or tax returns to verify your income. This process usually takes one to three business days, though some lenders offer same-day decisions.
The lender will then send you a preapproval letter stating the loan amount, the interest rate, and the term (usually 36 to 72 months). This letter is what you bring to the dealership. It shows the dealer you have financing lined up and that you're a serious buyer.
If you want to compare rates from multiple lenders, do it within a two-week window. Credit bureaus treat multiple auto loan inquiries made close together as a single search, so your credit score will take only one small hit instead of one for each inquiry. After two weeks, each new inquiry counts separately and can lower your score more.
What preapproval does and does not may provide
A preapproval does not lock in your interest rate. If market rates rise between the time you get preapproved and the time you actually buy the car, your final rate could be higher. Some lenders offer a "rate lock" for an extra fee, which guarantees the rate for a set period — usually 30 to 60 days — but this is not automatic.
A preapproval also does not may provide final approval. The lender can still deny you if your employment changes, your credit score drops significantly, or if you miss a payment on another account between preapproval and purchase. The lender will also verify your employment by calling your employer, and if that verification fails, approval can be withdrawn.
The preapproval is tied to you, not to a specific car. You can use it to buy any car within the approved amount. However, if you buy a car that is significantly older, has very high mileage, or is in poor condition, some lenders may refuse to finance it even though you're preapproved, because the car itself is considered too risky as collateral.
Using your preapproval at the dealership
Bring your preapproval letter to the dealership. Tell the salesperson you have outside financing and show them the letter. This signals that you're not dependent on the dealership's financing and that you know your budget.
The dealership may still offer you financing — sometimes at a better rate than your preapproval, sometimes worse. Compare the two offers carefully. Look at the interest rate, the loan term, and the total amount you'll pay over the life of the loan. If the dealership's offer is worse, decline it and use your preapproved loan instead.
Some dealerships will try to convince you that their financing is better or that you need to finance through them to get a warranty or rebate. This is usually not true. Warranties and rebates are separate from financing, and you can get them whether you use the dealership's loan or your own. If a dealership insists otherwise, that's a sign to shop elsewhere.
Once you've agreed on a car and a price, you'll contact your preapproval lender to finalize the loan. You'll provide the car's details — make, model, year, VIN, and purchase price — and the lender will do a final verification of your employment and credit. If everything checks out, the lender will send the money to the dealership or to you, depending on the arrangement you made.
When preapproval makes sense and when it doesn't
Preapproval makes sense if you're shopping around, want to know your budget before you visit a dealership, or want to compare the dealership's financing offer to an outside offer. It also makes sense if you have fair or average credit and want to lock in a rate before shopping, because rates can vary significantly based on credit score.
Preapproval is less useful if you have excellent credit and can get a very low rate from the dealership itself, or if you're buying a used car from a private seller who may not accept outside financing. It's also unnecessary if you're paying cash or if you're buying from a dealership that offers special financing deals (like zero percent for 60 months) that are better than what you'd get from a bank.
If you're not sure whether to get preapproved, the answer is usually yes. There's no cost to get preapproved, and it takes only a few minutes. The worst case is that you have a preapproval letter you don't use. The best case is that you discover the dealership's financing is worse than your preapproval, and you save money by using your own loan.
How preapproval affects your credit score
When a lender pulls your credit report to consider you for a preapproval, that inquiry shows up on your credit report as a "hard inquiry" or "hard pull." A single hard inquiry typically lowers your credit score by a few points — usually five to ten points — and the impact fades over time.
If you explore for preapprovals from multiple lenders within a two-week window, credit bureaus count all those inquiries as a single search for auto financing. This means you take only one small hit to your score, not one for each lender. This is by design, to encourage you to shop around without penalty.
After two weeks, the window closes. Any new preapproval inquiries after that will be counted separately, and each one will lower your score a bit more. So if you're going to shop around, do it all within two weeks.
The impact of hard inquiries fades quickly. After a few months, the inquiry has almost no effect on your score. After one year, it falls off your credit report entirely. So even if you take a small hit now, it won't affect your ability to get other credit in the near future.
Preapproval versus prequalification
A prequalification is a preliminary estimate based on information you provide, but the lender has not verified any of it. You might fill out a form on a website saying you make $60,000 a year, and the lender gives you a rough estimate of what you could borrow — but they haven't checked your credit, haven't called your employer, and haven't seen any documents.
A preapproval, by contrast, involves a hard credit check and verification of at least some of your information. It's a more serious offer and carries more weight with a dealership.
Prequalifications are useful for getting a ballpark idea of your budget without any impact on your credit score. Preapprovals are useful when you're ready to actually shop and want a concrete offer from a lender. If a lender offers you a prequalification and you want to move forward, you can usually convert it to a preapproval by providing more information and allowing a credit check.
Frequently Asked Questions
Can I get preapproved if I have bad credit?
Yes, but your interest rate will be higher. Lenders offer preapprovals to borrowers across the credit spectrum, from excellent to poor. If your credit score is low, you may still get preapproved, but the rate will reflect the higher risk. Getting preapproved lets you see what rate you'd actually get, rather than guessing.
Does preapproval mean the dealership has to accept it?
No. The dealership can decline your outside financing and insist you finance through them, though this is rare. More commonly, the dealership will accept your preapproval but will also offer you their own financing option for comparison. You're free to use either one, or to walk away if neither works for you.
What if my preapproval expires before I find a car?
Contact your lender and ask for an extension or a new preapproval. Most lenders will renew a preapproval if your credit and employment haven't changed. The process is usually quick and may not require another hard credit check, depending on the lender's policy.
Can I use a preapproval from one lender and then finance through a different lender?
Yes. A preapproval is just an offer. You're not obligated to use it. You can get preapproved from Bank A, then decide to finance through Bank B, a credit union, or the dealership instead. However, each new lender will do their own credit check, so you'll take multiple hard inquiries if you wait too long between applications.
Does preapproval cover the down payment?
No. A preapproval is for the loan amount only. The down payment comes from your own money. If you're preapproved for $20,000 and the car costs $25,000, you'll need to provide the $5,000 down payment yourself. Some lenders allow you to roll the down payment into the loan, but that increases the total amount you borrow and the interest you pay.
