Your local car dealership (be it Chevy, Kia, or Mercedes) is less a retail outpost and more a carefully engineered, multi-staged financial cyclotron. After working in dealerships for a few years in my University days, I learned that most dealership profits are made in the service department. Car finance is the second most profitable part of the car business, and used car finance is very profitable. Actually selling cars makes up only about 30% of a dealerships profits:
We hit so called “Peak Auto” of roughly 16 million units a decade ago; in 2025 we buy only about 15 million vehicles. That fact combined with dealers crying about the loss of business to direct sales (like Tesla) and the constant screaming about thinner margins, lead me to think that used car profits were now larger than new car profits. However after watching a few video’s from reliable sources (see the CNBC screenshot above) and doing my own research, it turns out I am wrong… sort of.
How Much Does a Car Dealer Make On a Vehicle?
According to Presidio Group, dealers made about 25% less on a used vehicle than they do on a new vehicle in Q2 of 2025:
However, there is more to used car profits than just the sale price. Used car buyers:
- pay MUCH higher interest rates on car loans than new car buyers
- often buy used car warranties and services that new car buyers have no interest in
- need more repair work in the future and usually return to the dealership for that work
Let’s walk through the math that makes used cars even more profitable that used cars.
The Car Profit Blueprint: Gross vs. Net Margin Dynamics
The used vehicle is disproportionately vital to a dealership’s financial health, despite lower transactional profitability compared to new cars.
| Vehicle Type | Average Gross Profit Per Unit (Q2 2025) | Ratio to New Car Profit |
| New Vehicle | USD $2,128 | 100% |
| Used Vehicle | USD $1,567 | ~74% |
The used vehicle department accounts for nearly 25% of a dealer’s total gross profit (including Finance & Insurance, or F&I). This transaction is merely the ignition switch for the dealership’s true Power Core: Service and Parts (generating approximately 50% of gross profit) and “F&I” (selling high-margin warranties and loans). Even better, the used car feeds the service bay, creating a decade or longer of high profit backend revenue.
Commission Effects?
The $1,567 Gross Profit per used vehicle is deceptively high because it excludes the cost of the sales team required to close the deal. Commissions are categorized as Operating Expenses (Overhead), not Cost of Goods Sold, and are thus subtracted after Gross Profit is calculated.
The typical used car commission structure pays a salesperson 20% to 30% of the Front Gross Profit, incentivizing them to maximize that margin. This commission structure fuels high earning potential: the average US used car salesman earns $60,321 annually but that includes ALL used car salesman.
We do not have specific numbers for used car salesman at new car dealers but we expect they are in the top 25% which would bring them to $68,950/ year. The top-performing 10% of used car sales staff make $76,807 and the very best of the best routinely exceed $100,000 per year.
- Front-End Commission: Top performers are usually on a tiered plan, placing them at the highest commission rate, typically 25% to 30% of the gross profit. This yields a base commission of approximately USD $390 to $470 per vehicle.
- Back-End Commission: The true leverage for a top earner lies in selling high-margin Finance & Insurance (F&I) products (warranties, gap insurance, etc.). Top sales professionals consistently achieve high F&I “penetration,” earning an additional percentage (typically 5% to 7%) of this back-end gross profit, which can easily add $100 to $300 per car!
This makes the sales team a significant cost center that converts the high Gross Profit into the thin 1-3% Net Profit margin that defines the dealership business.
The Margin Gap: Gross Profit vs. Net Profit
The difference between the high Gross Profit per unit ($1,567) and the final, low-single-digit Net Profit Margin is the sum of a dealer’s Operating Expenses (Overhead).
- Gross Profit is calculated by subtracting only direct costs (vehicle acquisition and reconditioning) from sales revenue
- Net Profit is the Gross Profit minus all Overhead.
This overhead, which typically consumes 97% of total revenue, includes costs not directly tied to a single car, such as:
- Personnel: Management salaries, and administrative wages
- Facility: Property taxes, rent/mortgage payments, and utilities (electricity, gas)
- Administrative: Advertising, floorplan interest (borrowing cost for inventory), and legal fees
Global Profit Protocols: The International Circuit
The US model of robust gross profit per unit is not universally replicated. Global markets often see dealers operating with thinner margins, placing greater emphasis on volume and supplementary income.
- United Kingdom (UK): Dealers target £2,000 to £2,500 gross margin on volume sellers, but the final net profit is often a narrow 2% to 5% due to high operational costs
- Canada: Used car dealers posted a national pre-tax profit margin of just 2.3% in 2023, with profitability highly volatile based on vehicle segment (e.g., SUVs vs. Sedans)
- European Union (EU): Across the broader EU, dealer gross margins on used vehicles generally average near 7%, reflecting a more structured, high-volume environment
The global data confirms that the future of used car profit is tied to supply acquisition (trade-ins vs. auctions) and defending the F&I/Service moat from digital disruptors like Amazon, which threaten dealer inventory.
The Cost of Quality: Risks of Used Vehicle Reconditioning (Recon)
New car dealers typically sell the best quality used vehicles (and they auction off the rest), sometimes requiring significant investment in reconditioning to meet high standards or qualify for Certified Pre-Owned (CPO) status.
A dealer’s average spend on recon is often over USD $1,300 per unit, covering:
- Mechanical/Safety: Engine work, brake repairs, fluid flushes, safety inspections, and the replacement of worn parts like new tires or windshields
- Cosmetic/Aesthetic: Professional cleaning, detailing, scratch removal, paintless dent repair (PDR), and interior fabric/leather repair
This investment ensures a higher retail price and stronger customer loyalty, but it confirms the used car’s complexity: it’s not a simple retail transaction but a full-scale re-manufacturing process.
Don’t let the dealer tell you they poured a lot of money into the car to get it to their quality standard. The dealer expected that cost and this does not effect the their average gross profit of about USD $1600 per vehicle, but what is not included is risk.
Sometimes a dealer buys a good looking vehicle only to find that it needs a lot of work and so they can actually loose money on sale price of the vehicle. Dealerships mitigate that risk by inflate their margins just a bit, on all used vehicles, to cover that risk.
The Wrap
New car dealers rely on used vehicle sales not for their high transactional profit, but as a critical feeder for the highest-margin departments: Service and F&I (Finance & Insurance).
The average used car generates a $1,567 Gross Profit (after the $1,300+ reconditioning cost is covered). However, this high figure is quickly absorbed by Operating Expenses (Overhead) like facility costs and sales commissions.
The typical salesperson’s commission for a top performer averages $700 to $800 per unit (including front-end profit and back-end F&I sales), ultimately driving the dealership’s true bottom line, an exceptionally thin 1-3% Net Profit margin.
So now you know, what you need to know to buy a used car from your local dealership.
