Gross margin per car: what is actually left
The gross margin of a car dealer is the difference between the retail selling price and the purchase price of the vehicle. Without other costs. Only the difference between what you paid and what you charged.
In the Spanish second-hand vehicle market in 2025 and 2026, the usual ranges are as follows:
Type of vehicle | Typical purchase price | Usual gross margin |
|---|---|---|
Economic city car (up to €5,000) | €2,000-€4,500 | €500-€1,000 |
Mid-range saloon/SUV (€5,000-€15,000) | €7,000-€12,000 | €1,200-€2,500 |
Premium SUV or high-end saloon (€15,000-€30,000) | €16,000-€25,000 | €2,500-€5,000 |
Luxury or classic vehicle (+€30,000) | Variable | Variable, can exceed €8,000 |
These margins are gross. They do not include any operating costs. They are simply the difference in price.
The average gross margin of the sector for an independent medium-sized dealership (between 15 and 60 cars per month) lies between 1,500 and 2,200 euros per vehicle. Dealers working in lower segments or who face high local competition may be below 1,000 euros of gross margin.
The costs that reduce the margin and which many underestimate
Here is the real problem of many car dealers: they calculate the gross margin well but do not track costs properly, and the result is that they work hard to earn less than they think.
Vehicle preparation. Cleaning, servicing, replacing basic parts (tyres, brake pads, filters), repairing minor dents. For a mid-range vehicle, professional preparation costs between 300 and 800 euros. If you prepare 20 cars a month, that is between 6,000 and 16,000 euros monthly of preparation costs alone.
Advertising and portals. The presence on portals such as coches.net, AutoScout24, Wallapop or Milanuncios has variable costs. A professional plan on the main portals can cost between 400 and 1,500 euros per month, depending on the number of adverts and the featured options hired.
Document management and administration. Each transfer of ownership has an administrative processing cost of between 50 and 150 euros. With 20 sales per month, that is between 1,000 and 3,000 euros. Add the vehicle history reports prior to purchase (between 15 and 30 euros per vehicle) and the possible regularisation costs of any vehicle with issues.
Stock financing. If you have funded stock, each car generates interest while in inventory. At an annual rate of 7% and with an average purchase value of 9,000 euros per vehicle, each day in stock costs approximately 1.73 euros per car. If you have 25 cars and they take 60 days on average to sell, that is 2,595 euros in interest.
The cost of having a car sitting in stock is higher than it seems when all factors are calculated.
Rent or mortgage of the premises. Premises of between 500 and 1,500 m² in an area with reasonable traffic in Spain can cost between 1,500 and 5,000 euros per month in rent, depending on the city and location.
Staff. A sales representative with a basic salary of 1,400 euros gross plus commissions represents a total cost for the company of between 1,800 and 2,200 euros monthly. Many dealers work alone at the start, but from 20-25 cars per month, it becomes difficult without help.
Taxes and social contributions. As a self-employed person (autónomo), the minimum Social Security contribution in 2026 is 320 euros monthly. If you pay tax as a company, corporation tax (25% of profit) must be added. The personal income tax (IRPF) of the self-employed person is calculated on the net profit.
The REBU is the tax scheme that allows dealers to pay tax only on the margin: this guide explains how it works and how to apply it correctly
How many cars you need to sell to have a profitable business
With the previous ranges, a realistic estimate for an independent car dealer working alone or with one employee:
A dealer selling 10 cars a month with an average gross margin of 1,800 euros obtains 18,000 euros of gross margin. If their monthly fixed and variable costs (premises, portals, preparation, administration, insurance, self-employed contribution) are 8,000-10,000 euros, their net profit before tax is between 8,000 and 10,000 euros. Annualised, it is between 96,000 and 120,000 euros gross. After IRPF or corporation tax, the actual net profit is between 65,000 and 85,000 euros.
A dealer selling 5 cars a month with the same gross margin has 9,000 euros of gross margin. With the same fixed costs, they may run into a loss or a very tight profit. The usual break-even point for an independent dealer is around 7-8 cars sold per month.
These are averages. A dealer specialising in high-end vehicles with margins of 4,000-5,000 euros can make a good living selling 4 or 5 cars a month.
Having clear concessionaire KPIs is essential to know where the actual profitability of your business stands at any given moment.
Differences in profitability depending on the vehicle segment
Not all segments are equally profitable. Data from the sector shows significant differences:
Cheap city cars (up to 5,000 euros) have low margins in absolute terms but fast turnover. These are cars that sell in less than 30 days if the price is right. The problem is that preparation costs are proportionally high relative to the margin.
Mid-range SUVs (between 8,000 and 18,000 euros) are the sweet spot of the Spanish market. High demand, reasonable margins (1,500-2,500 euros) and buyers who generally accept financing, which can generate additional income from the finance company's commission.
To accurately calculate the margin left by each transaction, this guide for calculating gross and net margin on used cars is the starting point
Premium second-hand vehicles (from 20,000 euros) have higher margins in absolute terms but more risk: more demanding buyers, higher probability of complaints, higher preparation costs and lower demand. They require greater technical and commercial expertise.
Second-hand electric vehicles are in a moment of uncertainty: demand is growing but supply is too, and prices have fallen significantly since 2022. In 2025 and 2026 there are opportunities in electrics but also more risk of buying above market price if not monitored properly.
What variables separate the most profitable car dealerships
Dealers who consistently rank high in the sector's profitability range share several patterns:
They buy better than average. They have access to sourcing channels that give them a price advantage: professional auctions, direct relationships with leasing companies, agreements with workshops that bring them private vehicles. Profitability starts with the purchase, not the sale.
The sourcing channels where dealers buy make the difference in the entry cost of stock
They control the days in stock per vehicle. They know at all times which cars have been in inventory for more than 45 days and take action: they lower the price, increase visibility on portals or call buyers who have already shown interest. Idle cars are the biggest margin destroyer in the sector.
They sell additional services. Extended warranty, car insurance, buyer financing: each of these services can generate between 200 and 600 additional euros per transaction. A dealer who closes 40% of their sales with financing and 30% with an extended warranty significantly improves their profitability per vehicle.
They keep operating costs under control. They do not oversize the premises, do not hire more staff than necessary and use tools that automate publishing on portals and document management so as not to pay for repetitive work.
How much the owner makes: real salary of the self-employed person or entrepreneur
The most common confusion among dealership owners is mixing business profit with their personal salary. They are not the same thing.
If you have a company with a net profit of 80,000 euros a year, that does not mean you make 80,000 euros. If you pay yourself a salary of 30,000 euros gross as a manager, that salary is a company expense. Profit after salary and corporation tax can be 35,000-40,000 euros, which you can distribute as dividends or reinvest.
As a self-employed person, the net profit is your IRPF taxable base. With a net profit of 70,000 euros, the tax bill in 2026 (state IRPF bands plus regional ones) can exceed 25,000 euros. The actual net available would be about 45,000 euros.
An independent dealer selling 12-15 cars a month with well-controlled operations can have a personal net income of between 40,000 and 70,000 euros annually. One selling 5-7 cars a month can be between 20,000 and 35,000 euros. Extremes exist in both directions.
Dealcar and real-time margin control
One of the most common problems in dealerships with several vehicles in stock is not having clear visibility of the actual margin for each car. The purchase price and the sales price are known, but preparation costs, financing days and administration expenses get mixed up, and at the end of the month, it is difficult to know exactly how much each deal has generated.
Form Dealcar, you can record all costs associated with each vehicle from the moment of purchase, allowing you to see the real net margin on each operation and make more informed decisions about the sale price and rotation priority. If you want to see how it works, you can request a demo at dealcar.io.
Frequently asked questions
Is it necessary to be registered as a car dealer to sell cars regularly?
Yes. If you sell vehicles regularly for profit, you are required to register as a car dealer under the corresponding IAE heading and pay tax on that activity. The occasional sale of one's own vehicles has a different tax treatment, but beyond a certain number of annual transactions, the Tax Agency may consider that there is an economic activity even if you are not registered.
Is the margin on second-hand electric cars different?
In 2025 and 2026, the margin on used electrics has more variance than on combustion vehicles. The depreciation of some models has been very aggressive, which creates cheap buying opportunities but also the risk of the market continuing to fall after purchase. Dealers experienced in electrics are getting good results on high-demand models like the Tesla Model 3 or the Volkswagen ID.4, but the technical and market knowledge required is higher than in combustion.
How much can be earned from buyer financing?
Financial intermediation commissions vary by entity and volume. For an independent dealer, the average commission per financed transaction is typically between 1% and 3% of the financed capital. On a 12,000 euro vehicle with 80% financed (9,600 euros), that represents between 96 and 288 additional euros per transaction.
What is the difference between invoicing with REBU or normal VAT?
The REBU (Special Scheme for Second-Hand Goods) allows dealers to pay VAT only on the transaction margin, not on the total sale price. This significantly reduces the tax burden on buyer-seller operations with private individuals, where there is no purchase invoice with VAT. Using the REBU correctly is one of the factors that most impacts the tax profitability of a dealer.
Is it more profitable to specialise in a segment or have a varied stock?
Sector data suggests that dealers specialising in a specific segment usually have better margins than generalists, because they know the market better, have better sourcing channels and build more trust among buyers in that segment. However, specialisation also implies more risk if the demand for that segment drops.
