Dealership Expense Benchmarks 2026: Operating Costs by Category | DealerInt

Why expense benchmarking matters

Revenue growth does not guarantee profit growth. A dealership can sell more vehicles, generate more F&I income, and increase service traffic—and still see net profit decline if expenses outpace revenue. Expense discipline is the other half of the profitability equation, and it requires the same rigor as gross profit management.

Benchmarking your dealership's expenses against industry averages reveals where you are efficient, where you are overspending, and where improvement will have the most impact. The most useful benchmark basis is expenses as a percentage of total gross profit, because gross profit is the money available to cover costs. A store with high gross and high expenses may look fine on revenue but poor on net margin. Percentage-of-gross analysis reveals the truth.

The major expense categories

Dealership operating expenses fall into five major categories. Each has industry benchmarks that vary by franchise, market, and store size, but the ranges below represent NADA composite data and 20-group averages for 2024–2026:

1. Personnel expense (48–55% of gross profit)

Personnel is the single largest expense at any dealership. It includes:

• Sales staff compensation (base + commission)
• F&I manager compensation
• Sales management compensation
• Service advisor and technician compensation (if not in COGS)
• Parts staff compensation
• Administrative and back-office staff
• Management (GM, controller, office)
• Benefits (health insurance, retirement, PTO)
• Payroll taxes

Benchmark: Well-run stores keep total personnel expense between 48% and 52% of gross profit. Stores above 55% are overstaffed, underpaying (and compensating with headcount), or underproductive. Stores below 45% may be understaffed, which manifests as burnout, turnover, and missed opportunities.

How to reduce personnel expense without cutting headcount:

• Increase productivity — More deals per salesperson, more hours per service advisor, more ROs per technician. Volume per head is the most sustainable efficiency lever.
• Realign incentives — Ensure commission structures reward profitable behavior, not just volume. Flat-rate commissions on gross (not revenue) align incentives with dealership goals.
• Reduce turnover — Replacing a salesperson costs $15,000–$25,000 in recruiting, training, and lost productivity. Retention through culture, training, and fair pay is cheaper than constant hiring.
• Automate admin — BDC scheduling, DMS data entry, and report generation can be partially automated, reducing headcount needs for non-customer-facing roles.

2. Advertising (7–9% of gross profit)

Advertising has shifted decisively toward digital. The average franchise dealer spends $600–$800 per new vehicle retailed on advertising. As a percentage of gross profit, total advertising should run 7–9%.

Breakdown by channel:

Stores spending more than 9% of gross on advertising should audit their channel mix. Common waste areas: legacy TV or radio buys with declining ROI, overlapping third-party listing subscriptions, and OEM-mandated programs that don't generate measurable traffic.

Cost per vehicle retailed is a more actionable metric than percentage of gross for advertising specifically. If you spend $150,000 per month on advertising and retail 200 units, your cost per unit is $750. If a peer retails 250 units on the same spend, their cost is $600. The gap is either market-driven or efficiency-driven—and it is worth understanding which.

3. Floorplan interest (3–5% of gross profit)

Floorplan is the cost of financing vehicle inventory. It is a variable cost driven by three factors: interest rates, inventory levels, and turn speed. In the current rate environment (2024–2026), floorplan interest has become a more significant expense than during the low-rate era of 2015–2021.

Benchmark: 3–5% of gross profit. Stores above 5% are either carrying too much inventory, turning too slowly, or both.

Levers to reduce floorplan cost:

• Faster turn — Every day a vehicle sits on the lot is a day of carrying cost. A 45-day turn target for used vehicles and aggressive pricing on aged new inventory reduces average days in inventory.
• Right-size inventory — Carrying 90-day supply in a 60-day market creates unnecessary interest expense. Match inventory to actual sales pace.
• Negotiate floorplan terms — Rates are not always fixed. Large groups and high-turn stores can negotiate better terms, credit offsets, and longer interest-free periods.
• Leverage manufacturer credits — Most manufacturers offer floorplan assistance. Ensure these credits are captured and properly applied.

4. Rent and facilities (8–12% of gross profit)

Occupancy costs include rent (or mortgage payments), property taxes, utilities, maintenance, insurance, and any franchise-required facility upgrades. This is a semi-fixed cost—it does not change with sales volume, which means it hurts disproportionately in slow months.

Benchmark: 8–12% of gross profit. Stores at the high end are often in expensive real estate markets (coastal metro areas) or carrying the cost of recent OEM-mandated facility upgrades (image programs).

Facility costs are difficult to reduce in the short term. Long-term strategies include renegotiating leases, consolidating operations (shared prep centers, centralized BDC), and evaluating whether satellite lots or offsite storage reduce total cost.

For stores that own their real estate, the imputed rent (what the property could earn on the open market) should be included in this calculation to provide an apples-to-apples comparison with leasing stores.

5. Other expenses (10–15% of gross profit)

The "other" category includes:

• Technology and software — DMS fees, CRM, website platform, desking tools, inventory management, digital retailing, and other SaaS subscriptions. Average: 2–3% of gross.
• Insurance — General liability, garage keepers, property, workers' comp. Average: 2–3% of gross.
• Professional fees — Legal, accounting, consulting. Average: 1–2% of gross.
• Office and shop supplies — A small but persistent expense. Average: 1% of gross.
• Training — Sales, F&I, service, management development. Average: 0.5–1% of gross.
• Miscellaneous — Everything else. Should be less than 2% of gross.

Technology costs deserve special attention. Many dealerships accumulate software subscriptions over time without rationalizing the stack. A quarterly technology audit—listing every subscription, its monthly cost, its primary user, and its measurable impact—often reveals redundancies and unused tools.

Expense benchmarks by store type

Expense structures vary by franchise type and store size. Directional benchmarks:

Luxury stores tend to have higher facility costs (OEM image requirements) but lower advertising costs per unit (brand carries more weight). Domestic stores often have higher personnel and advertising costs due to competitive market dynamics and higher incentive complexity.

How to benchmark your store

Effective benchmarking requires consistent data and appropriate peers. Steps:

1. Standardize your chart of accounts — Use the NADA/NCM standard format. If your accounting system uses custom categories, map them to NADA equivalents before comparing.

2. Calculate each expense category as a percentage of total gross profit — Not revenue. Gross profit is the denominator that makes comparisons meaningful across stores of different sizes and revenue mixes.

3. Compare to NADA composites — NADA publishes annual composite data by franchise. Your manufacturer may also provide performance benchmarks through its dealer reporting system.

4. Join a 20-group — Peer performance groups (NCM, NADA 20-group, or private) provide monthly benchmarking with stores of similar size, franchise, and market. The accountability and specificity of 20-group data is significantly more useful than industry averages.

5. Trend over time — A single month's data is noisy. Look at trailing 3-month and 12-month trends. Is personnel expense creeping up? Is advertising yield improving or declining? Is floorplan cost per unit rising?

6. Investigate outliers — If any category is more than 2 percentage points above benchmark, investigate. The cause may be legitimate (market-specific factors) or addressable (inefficiency, waste, drift).

The hidden expense: uncontrolled overrides

There is one "expense" that never appears on the financial statement: the margin lost to uncontrolled pricing overrides. When a desk manager gives away $1,000 to match a competitor, that is not an expense line—it is a reduction in gross profit. When an F&I manager waives a $500 product, the F&I line is lower, but there is no "waiver expense" to explain it.

The effect is the same as an expense: net profit is reduced. But because it is invisible in standard accounting, it is not benchmarked, not tracked, and not managed. Industry estimates suggest 2–5% of gross profit is lost to uncontrolled overrides. On a store generating $8 million in gross, that is $160,000–$400,000 per year.

Treating overrides as an expense category—measuring them, benchmarking them, and managing them—is the single highest-ROI expense management initiative most dealerships can undertake. DealerInt provides this capability by capturing every override reason, aggregating the data, and surfacing patterns that leadership can act on.

Building an expense management discipline

Expense benchmarking is not a one-time exercise. It is a discipline. The most profitable dealerships review expense ratios monthly, benchmark quarterly, and audit annually. They challenge every category, renegotiate vendors regularly, and hold department managers accountable for their expense lines.

Start with the big three: personnel, advertising, and floorplan. These account for 60–70% of total expenses. Get them to benchmark levels and net profit improves immediately. Then address facilities, technology, and the rest. Layer on override visibility to capture the hidden expense that financial statements miss.

The goal is not cost-cutting for its own sake. The goal is efficiency—spending the right amount in each category to generate maximum gross profit with minimum waste. When expenses are lean and gross is strong, net-to-gross ratios climb toward the 15–20% range that separates top performers from the pack.
