How Each Financing Path Works
When you finance a car, money flows differently depending on which path you choose. Understanding that difference is the first step to making a sound decision. For a deeper grounding in loan mechanics, see our guide to how auto loans work — it covers APR, term length, and how monthly payments are actually calculated.
Dealer Financing (Indirect Lending)
When you finance through a dealer, the dealership acts as a middleman. It submits your credit application to one or more lenders, receives a rate offer, and then typically presents you with a rate that may include a markup — often called a "dealer reserve." The dealer earns a portion of the interest you pay over the life of the loan. This is legal and widespread; it's simply part of how dealership finance offices generate revenue.
Bank or Credit Union Financing (Direct Lending)
With direct lending, you apply for a loan with a financial institution before or after choosing a vehicle. If approved, you receive a pre-approval letter stating the maximum loan amount and interest rate. At the dealership, you negotiate the vehicle price independently of financing, then use your pre-approved funds to complete the purchase. Credit unions — which are nonprofit, member-owned cooperatives — often offer rates below those of commercial banks, though terms vary.
| Criterion | Dealer Financing | Bank or Credit Union |
|---|---|---|
| Rate transparency | Rate may include markup | Rate quoted is rate paid |
| Convenience | Single-location process | Requires separate application step |
| Promotional rates | Sometimes available (manufacturer-subsidized) | Not applicable |
| Negotiating leverage | Limited without outside benchmark | Strong with pre-approval in hand |
| Credit union membership required | No | Yes (credit unions only) |
| Typical approval speed | Same day at dealership | Hours to a few business days |
| Best scenario | Qualifying promotional APR offer | Standard-rate vehicle purchase |
The Rate Markup Reality
One of the most consequential differences between the two paths is rate transparency. With direct lending, the rate you're quoted is the rate you pay. With dealer financing, the lender's actual buy rate — the rate the lender would accept — may never be disclosed to you. The dealer can mark that rate up within limits set by the lender, often by 1–2.5 percentage points.
Over a 60-month loan, even a 1.5% markup on a $30,000 vehicle adds up to a meaningful difference in total interest paid. Your credit score shapes the base rate you're offered regardless of channel — borrowers with stronger profiles have more room to compare and negotiate.
Promotional rates — often advertised as 0% or very low APR through manufacturer captive finance arms — are a genuine exception. These subsidized rates are funded by the automaker (not the dealer's markup) and can be excellent value. The catch: they typically require top-tier credit, apply only to specific models or trim levels, and may be structured with shorter terms than standard loans.
1–2.5%
Typical dealer rate markup range
Lenders generally allow dealers to mark up the buy rate by up to 1–2.5 percentage points, depending on lender agreements and loan term.

New-car buyers who finance through dealership
Industry estimates consistently show the majority of new-vehicle buyers use dealer-arranged financing, in part due to convenience and promotional offers.

Most common new-car loan term
According to Experian automotive finance data, 60-month terms are the most frequently chosen for new-vehicle purchases in the U.S.
Using Pre-Approval as a Negotiating Tool
Getting pre-approved by a bank or credit union before you shop is less about commitment and more about information. A pre-approval gives you three things: a realistic rate benchmark, a ceiling on what you can borrow, and the ability to walk into a dealership without urgency around financing.
When you separate the price negotiation from the financing conversation, you avoid one of the more common dealership dynamics — monthly payment anchoring. Some finance offices focus discussions on monthly payment rather than total vehicle price or interest rate, which can obscure the true cost of the loan. Knowing your pre-approved rate lets you evaluate any dealer counter-offer on equal terms.
If the dealer can beat your pre-approved rate after you've negotiated the vehicle price, that's a straightforward win. If not, you simply use your pre-approval. Either way, you're not entering the finance office without a reference point.

Which Path Makes Sense for You
Neither option is universally better. The right choice depends on your credit profile, the vehicle you're buying, and how much time you want to invest before arriving at the lot.
If you're buying a new vehicle from a brand running aggressive promotional financing, it's worth checking whether you qualify — and then comparing that offer against what a bank or credit union would provide. If a subsidized promotional rate is available and you qualify, it may outperform anything on the open market.
If you're buying a used vehicle or a model without promotional offers, direct lending through a bank or credit union generally gives you more transparency and a stronger negotiating position. Shopping at least two or three lenders — including a credit union if you have membership access — gives you a reliable rate range to work with.
If financing is one part of a broader decision about whether to buy at all, it's also worth reviewing how leasing compares structurally before committing to a purchase loan. The two paths involve meaningfully different obligations and long-term costs.
