Why Do Dealerships Want You to Finance Instead of Paying Cash?
Published August 6, 2025
You’re at the dealership and you finally found the perfect car, negotiated a fair price, and then the salesperson asks, “Will you be paying cash or financing today?” Your first thought is probably, “Well, paying cash has to be the best right?” Today you’ll find out why dealerships want you to finance in-house.
How Dealership Financing Actually Works
First of all, dealerships make money a few different ways through financing, but one main one is called buy rate mark-up. The buy rate is the interest rate your lender approves you for. In some cases and depending on the lender agreement, the dealer is allow to mark up the interest rate up to 1%. They get to keep some of this depending on the agreement and how much interest is paid over the life of the loan. This is called reserve.
It’s important to remember that financing in-house isn’t automatically a bad deal. Often times, dealerships are able to offer competitive interest rates because they work with multiple lenders. You may even get the best interest rate from the dealership. The goal is the view the whole picture.
Depending on the lender agreement, the dealership has to pay back some or all of the reserve if the loan is paid or refinanced. The finance manager may ask you to keep the loan for 3 to 6 months. Not because you have to keep the loan that long, because they have to pay some or all of that money back if you pay it off.
When it comes to promotional offers from the dealer, like 0% financing, you might ask, “Why would they even finance it then?” Often times the manufacturer will give the dealership a kickback for the promotion and finance it through their own financial department. Depending on the company, there can be lots of different subsidies from the manufacturer such as promotional financing, warranties, and floorplan interest grace periods.
Speaking of Warranties…
When the finance manager comes out to greet you and bring you to the finance office, they get excited. Why? Because they get the chance to sell you various products for your new vehicle. They may introduce you to several products designed to provide value to your vehicle purchase. These products often have high markups such as $2000 for rust proofing that cost them $450. All of the products they sell you go directly to the dealership’s and sometimes, they will make it hard for you to cancel the products if they allow for it. Each dealership varies.
This doesn’t necessarily mean these products are malicious or rip-offs though and can pay themselves off sometimes. If you have a long term loan and little money down, GAP insurance can be a great purchase for you. Maybe you’re buying a 10 year old car and plan to keep it for a long time. The extended warranty might provide you a great deal of value. The value of each product depends on what you need, the situation, and the price you pay for them.
These financial products aren’t bad, they’re designed to truly provide value to you, but they come with high profit margins for the dealership and can serve as big chunk of the dealership’s profit. It can do a great deal to research these products and see if you can possibly find cheaper alternatives or to see if these products provide value to you.
How Can I Get The Best Possible Deal?
First of all, weigh the pros and cons of paying cash vs. financing. They may be the same or different, getting the whole picture is crucial.
Paying cash may make sense if:
You have enough savings remaining after the purchase.
The loan’s interest rate is too high
There are no incentives or rebates for financing
You want to immediately own the vehicle outright.
Financing may make sense if:
You qualify for low promo APRs.
Financing unlocks some sort of rebate or incentive.
You want to preserve cash for other goals or an emergency.
Your cash may earn more elsewhere than the interest the loan is accruing.
Ask Questions
The best salesman asks the best questions to land you on the right vehicle. The best buyer asks the best questions to make informed financial decisions.
The questions to ask:
What interest rate am I being offered?
How long do I have to keep the loan for?
Am I being offered buy rate?
Can I have an itemized breakdown of everything in this deal?
Is there a prepayment penalty?
Can I use this warranty anywhere?
Can I cancel this product later?
The Bottom Line
Dealerships aren’t asking you how you want to pay simply to converse. Financing is a major part in many dealerships business model through reserve, finance products, and manufacturer incentives. This doesn’t automatically mean financing through the dealer is bad, it simply means dealerships have strong incentives to offer it.
Your goal shouldn’t be to avoid financing or to avoid cash. Instead, I encourage you to understand how the process works, compare your options, and choose the method that best fits your financial decision. Remember, the best buyer asks the best questions.
Dealerships aren’t inherently bad. They can provide great value for many people. I’m not bashing dealerships, I’m here to inform you how some of these systems work so you can make informed financial decisions.
