Things to Know
Essential concepts for understanding your results
Rate ComparisonHow do dealer and credit union auto loan rates compare?
Credit unions typically offer rates 1-2% lower than dealership financing. Average rates: credit unions 5.5-7.5%, bank auto loans 6-8%, dealer financing 6.5-10%+ (varies widely). Exception: manufacturer promotional rates (0-2.9% through dealer) can beat any credit union — but these apply only to specific new models, require excellent credit, and often replace rebates worth $2,000-5,000. Always get a credit union pre-approval before visiting the dealer to have a benchmark.
Dealer MarkupHow do dealers make money on financing?
Dealers act as loan brokers — they submit your application to multiple lenders, receive rate quotes, then mark up the rate by 0.5-2% (the dealer reserve). If a lender approves you at 5.5%, the dealer may offer 7.0% — pocketing the 1.5% spread as profit. This is completely legal and adds $1,500-4,000 in interest on a typical loan. Having a pre-approved credit union rate in hand forces the dealer to match or beat it, eliminating their markup profit.
NegotiationHow do you use credit union pre-approval as leverage?
Get pre-approved before visiting any dealer. When discussing financing, let the dealer present their rate first. Then reveal your credit union rate: 'I am pre-approved at 5.5% through my credit union. Can you beat that?' Dealers can often match or beat your rate by reducing their markup — they would rather earn a smaller dealer reserve than lose the financing entirely. This one step typically saves $1,500-3,000 in interest over the loan term.
Total CostWhy is the monthly payment a misleading metric?
Dealers focus on monthly payments because stretching the term hides the total cost. A $30,000 loan at 7%: 48 months = $718/month, $4,455 total interest. 72 months = $513/month, $6,946 total interest. 84 months = $455/month, $8,208 total interest. The 84-month payment seems 'affordable' but costs $3,753 more than the 48-month loan. Always negotiate the total price and rate first, then choose the shortest term you can comfortably afford.

Dealers often markup interest rates by 1-3% above what the lender actually approved, keeping the difference as profit. Credit unions and banks offer direct-to-consumer rates without this markup, which is why pre-approval before visiting the dealer is so important.
Why Credit Unions Often Win
Credit unions are member-owned nonprofits that typically offer rates 0.5-2% lower than dealer financing. They don't add rate markups, and many waive origination fees. On a $30,000 loan, even a 1% rate difference saves $800-1,500 over the loan term.
When Dealer Financing Might Be Better
Manufacturers sometimes offer promotional 0% or very low rates through their captive finance companies. These special rates can beat even credit union rates — but they're usually available only to buyers with excellent credit and may require you to forgo other incentives like cash rebates.
Best Strategy: Get Pre-Approved First
Get pre-approved at your bank or credit union before visiting the dealer. This gives you a rate to compare against and negotiating leverage. If the dealer can beat your pre-approval, great. If not, you already have a better deal in hand.
How Dealer Financing Works
When you finance through a dealer, they act as a middleman between you and a lending institution. Dealers can mark up the interest rate by 1-3% above the bank's buy rate and keep the difference as profit. This is legal and common — it's one of the dealer's primary revenue sources beyond the vehicle sale itself.
Why Credit Unions Often Offer Better Rates
Credit unions are nonprofit member-owned institutions that return profits to members in the form of lower loan rates, higher savings rates, and fewer fees. Auto loan rates at credit unions are typically 1-2% lower than dealer financing, and they don't mark up rates. Membership requirements have also become very broad — many credit unions are open to anyone in a geographic area.
The Best Strategy
Get pre-approved at your credit union or bank before visiting the dealer. Then let the dealer try to beat your rate. Sometimes dealer financing through manufacturer captive lenders (like Ford Motor Credit or GM Financial) offers promotional rates (0-2.9%) that beat any credit union. Having a pre-approval gives you leverage and a fallback option.
