Where to Get a Used Car Loan: Credit Unions, Banks, Online Lenders, or Dealerships?

The Main Categories of Used Car Lenders

Used car loans come from several different kinds of lenders. Credit unions, banks, online lenders, and dealership financing are the four main options you will encounter. Each category has its own approach to rates, fees, and approval, so the best choice often depends on your credit profile and how much time you want to spend.

Credit Unions: Low-Rate, Membership-Based Lenders

Credit unions are not-for-profit cooperatives that serve their members. They typically offer lower loan rates than banks and dealerships because they return earnings to members in the form of better terms. To get a loan from a credit union, you must first become a member—usually by living in a certain area, working for an eligible employer, or belonging to a qualifying organization.

Because credit unions do not add the dealer markup that a dealership might, their rates tend to be lower than dealer-arranged financing. That makes them a strong first stop for borrowers with good or excellent credit. Membership requirements vary, so you will need to check with each institution to see if you qualify.

• Membership requirement: yes
• Approval criteria: relationship-based; credit union members may get more personalized underwriting

Banks: Familiar and Widely Available

Large national banks, regional banks, and community banks all offer used car loans. Banks are one of the leading sources of auto financing—as of Q1 2026, banks held a 30.7% market share of the auto loan market, according to Experian data cited by LendingTree. They generally offer competitive rates for borrowers with strong credit, and they often provide online applications and preapproval tools.

Like credit unions, banks tend to offer lower rates than dealer-arranged financing because they do not add a dealer markup. However, bank rates may not be as low as credit union rates for the same credit profile. Banks usually have stricter credit requirements than online lenders, which can be a hurdle for subprime borrowers.

• Convenience: many banks offer online preapproval and local branches

Online Lenders: Convenient and Subprime-Friendly

Online lenders operate entirely on the web, which can make the application process fast and convenient. Many online lenders allow you to prequalify with a soft credit check, so you can see potential rates without affecting your credit score. This can be especially helpful if you are still comparing options.

Online lenders may cater to a wider range of credit profiles, including those with less-than-perfect credit. However, rates for subprime borrowers can be high.

• Prequalification with soft credit check: offered by some online lenders
• Approval criteria: vary; some online lenders specialize in bad-credit loans
• Convenience: fully online application and customer service

Dealership Financing: Convenient but Often Priced Higher

Dealership financing is the process of arranging a loan through the car dealer itself. The dealership acts as an intermediary, submitting your application to one or more lenders and then presenting you with the best offer it receives. This can be the most convenient option because you can complete the purchase and financing in one place.

The catch is that dealerships often add a markup to the rate they receive from the lender. This markup—typically 1 to 2 percentage points—goes to the dealer as profit. Because of this addition, dealership-arranged rates are often higher than what you could get from a credit union or bank, even if you have good credit.

You can still negotiate the rate with the dealership, but it helps to come in with a preapproved offer from another lender so you have a benchmark. Understanding the markup and asking for a lower rate can save you money over the life of the loan.

• Rate transparency: may include 1–2% markup over buy rate
• Typical rates: often higher due to dealer markup
• Convenience: one-stop shopping for car and loan

How Rates and Fees Compare by Lender Type

Rates vary significantly by credit score, ranging from 6.30% for super-prime (781+) to 21.77% for deep subprime (300–500). Your actual rate will depend on your credit tier and the lender you choose.

Fees for car loans may include origination fees, application fees, documentation fees, and prepayment penalties. However, these fees are not applied uniformly; each lender sets its own fee schedule. In general, credit unions and banks may charge modest documentation or processing fees, while online lenders may include origination fees or higher rates to cover their costs. Dealership financing may include additional fees such as documentation or conveyance fees. When you receive a loan offer, ask for a complete breakdown of all fees so you can compare the total cost.

The table below summarizes what we know about typical rates and fee behavior by lender type. Keep in mind that rates and fees vary by institution and your personal credit profile.

Approval Requirements by Lender Type

Each lender type evaluates your creditworthiness differently. Credit unions often consider your relationship with the institution and may be more flexible with membership. Banks typically rely on strict credit scores and income verification. Online lenders may have more lenient credit standards and offer specialized products for subprime borrowers, but their rates can be higher. Dealership financing usually works with a network of lenders, which can help if you have unique credit challenges, but the markup may increase your rate.

Specific eligibility criteria—such as minimum credit scores, income thresholds, debt-to-income ratios, or employment history—are not uniform across lenders. For example, credit unions may require membership based on geographic area, employer, or affiliation, but the exact rules vary by institution. Banks often look for a credit score in the 'good' range (typically 670 or above) and a stable income, but each bank sets its own standards. Online lenders may accept lower credit scores but require proof of income and may charge higher rates to offset risk. Dealerships, through their lending partners, may have more flexible criteria but may also require a larger down payment or impose a higher APR. Always ask individual lenders about their specific approval requirements and documentation needs.

• Credit unions: membership required, often based on geography, employer, or affiliation; relationship history may help
• Banks: good credit (typically 670 or higher) and stable income often required, but each bank's criteria vary
• Online lenders: may accept lower credit scores and specialize in subprime; proof of income usually needed
• Dealerships: can access multiple lenders but may require higher down payments or accept higher APRs

How to Compare Offers Side by Side

When you are ready to compare loan offers, you can use a simple process to keep track of the numbers that matter. Start by gathering quotes from at least two different lender types—say, a credit union and an online lender—so you can see how they stack up.

For each offer, write down the APR, loan term, monthly payment, and any fees (such as origination fees or prepayment penalties). Also note the lender's requirements and any convenience factors, such as online application or local branch access.

Remember that APR is the annual percentage rate, which includes the interest rate plus certain fees. When comparing offers, always compare APRs rather than just the nominal interest rate.

• Check the APR, not just the interest rate
• Look at the total finance charge over the full loan term
• Ask about any upfront fees or penalties
• Preapproval from a direct lender (credit union, bank, or online) gives you a negotiating chip at the dealership
