Expert Guide: Should You Include Sales Commission Before Calculating Gross Margin?
The short answer is usually no for formal financial reporting and sometimes yes for internal profitability analysis. In most accounting frameworks, gross margin is meant to measure the relationship between revenue and the direct cost of producing or delivering the product or service. Sales commissions are commonly treated as selling expenses, which means they are generally recorded below gross profit, not inside cost of goods sold. However, many managers, founders, and revenue leaders still subtract commission before evaluating deal quality because they want a truer picture of what each sale contributes after variable selling costs. That is where confusion begins.
If you are asking, “Should I include sales commission before calculating gross margin?” you are really deciding between two different analytical goals. The first goal is external consistency: lenders, investors, auditors, and most financial statements expect gross margin to be based on revenue minus cost of goods sold. The second goal is internal decision quality: if commission changes with each sale, then excluding it can make a low-quality sale appear healthier than it really is. Both views can be valid, but they answer different questions.
What Gross Margin Is Supposed to Measure
Gross margin measures how much revenue remains after direct production or direct service-delivery costs are removed. In a product business, this typically includes raw materials, direct labor connected to manufacturing, freight-in, and other direct inventory-related costs. In a service business, this can include labor and delivery costs directly attributable to serving the client. The purpose of gross margin is to show how efficiently the company turns revenue into gross profit before operating expenses like sales, marketing, administration, and overhead.
That is why many accountants place sales commission below gross profit. Commission is generally tied to acquiring revenue, not producing the item sold. It is a selling expense. From this viewpoint, including commission inside gross margin can distort comparability across businesses and periods. Two firms with identical production economics may appear to have different gross margins simply because one uses salaried sales staff and the other uses high commissions.
Why Managers Sometimes Want Commission Included Anyway
Management teams often care less about textbook classification and more about economic reality. If a sale only occurs because a 12% commission is paid, that commission behaves like a variable cost of winning the order. For deal-level decisions, excluding commission can cause three problems:
- Overstated deal quality: A sale may look highly profitable on a gross margin basis even if commission consumes most of the residual value.
- Poor pricing decisions: Discounts may be approved because standard gross margin still looks acceptable, even though net contribution is weak.
- Misleading channel comparisons: Direct sales, inside sales, distributors, affiliates, and commissioned reps can have very different acquisition economics.
For these reasons, many sophisticated companies keep the formal gross margin metric intact while also tracking a second metric such as contribution margin, gross profit after variable selling cost, or sales contribution. This dual approach preserves accounting clarity without sacrificing operational insight.
Standard Financial Reporting vs Internal Analysis
Think of it this way:
- Financial reporting question: “How profitable is our product or service before sales and administrative overhead?”
- Managerial question: “How much money does this sale contribute after the variable costs needed to close it?”
These questions sound similar, but they are not identical. The first points to gross margin. The second points to contribution margin or unit economics. Trying to force one metric to answer both questions creates confusion.
Simple Formula Comparison
Here is the practical difference:
- Standard Gross Margin = (Revenue – Cost of Goods Sold) / Revenue
- Commission-Adjusted Margin = (Revenue – Cost of Goods Sold – Sales Commission) / Revenue
- Contribution Margin can also subtract other variable selling or fulfillment costs, not just commission.
Suppose your company sells a product for $100,000, cost of goods sold is $60,000, and sales commission is $8,000. Standard gross margin is 40%. If you subtract commission before the margin calculation, the result drops to 32%. Neither number is “wrong.” They simply represent different layers of profitability.
Industry Benchmarks Show Why Classification Matters
Comparability matters because gross margin varies dramatically by sector. A software company can support a much higher gross margin than a grocery or commodity distributor. If one company includes commissions inside gross margin and another does not, benchmarking becomes unreliable. The table below illustrates how broad the spread can be across industries using sector-level gross margin observations compiled by the NYU Stern margins database.
| Industry | Typical Gross Margin | Why It Varies |
|---|---|---|
| Software (System and Application) | About 71.5% | Low incremental delivery cost once the product is built. |
| Pharmaceuticals | About 66.7% | High intellectual property value and strong pricing power. |
| Retail (General) | About 27.6% | Competitive pricing and significant product acquisition costs. |
| Food Processing | About 29.9% | Material, packaging, logistics, and commodity cost pressure. |
Source context: NYU Stern publishes annual industry margin snapshots that are often used for benchmarking. If you include sales commissions in one business but not another, the benchmark loses meaning because the metric definition has changed.
Compensation Data Also Explains Why Sales Commission Is Usually Treated Separately
Labor statistics reinforce the idea that sales compensation is often viewed as a selling function rather than a production function. According to U.S. Bureau of Labor Statistics occupational wage data, compensation for sales professionals and sales managers is typically tracked separately from direct production labor. That distinction is one reason many finance teams classify commissions under selling, general, and administrative expense instead of cost of goods sold.
| Occupation | Median Annual Pay | Relevance to Margin Analysis |
|---|---|---|
| Sales Managers | $135,160 | Usually part of sales overhead, not product cost. |
| Wholesale and Manufacturing Sales Representatives | $73,080 | Compensation often tied to selling activity and commission structures. |
| Production Workers | Varies by manufacturing role | Direct labor may be included in inventory or cost of goods sold depending on role. |
These figures help explain the logic behind classification: production and delivery costs support gross margin, while selling labor and commissions often support operating expense analysis. Data source context: U.S. Bureau of Labor Statistics occupational outlook and pay data.
When You Should Exclude Sales Commission from Gross Margin
In most of the following cases, you should calculate gross margin without subtracting sales commission:
- External financial statements: Consistency and comparability matter most.
- Investor reporting: Investors expect gross margin to reflect production economics.
- Banking and covenant analysis: Definitions should stay stable and conventional.
- Board decks using benchmark comparisons: Industry averages usually assume standard gross margin definitions.
- Inventory-based accounting: Commission usually does not qualify as inventoriable cost.
If your objective is to compare your gross margin to competitors, peers, or historical internal periods, preserving the standard definition is usually the safest choice.
When You Might Include Sales Commission Before a Margin Calculation
There are still valid reasons to subtract commission before evaluating a sale. You may choose a commission-adjusted margin or contribution margin approach when:
- Commissions are directly variable by transaction.
- You are analyzing sales channel profitability.
- You are approving discounts or custom quotes.
- You need customer-level or rep-level economics.
- Your business has high sales acquisition cost variability.
In these situations, the key is not to relabel the result as standard gross margin unless your company has clearly defined and documented that internal version. A better label might be “gross margin after commission,” “contribution margin,” or “deal contribution.”
The Best Practice: Track Both Metrics
For most companies, the best answer is not choosing one metric forever. It is creating a metric stack:
- Revenue
- Gross Profit = Revenue – Cost of Goods Sold
- Gross Margin = Gross Profit / Revenue
- Contribution Profit = Gross Profit – Sales Commission – Other Variable Selling Costs
- Contribution Margin = Contribution Profit / Revenue
This layered model gives your accounting team, leadership team, and sales organization the specific lens each group needs. It also avoids endless debate over a single overloaded metric.
Common Mistakes to Avoid
- Mixing definitions across reports: If one dashboard includes commissions in margin and another does not, decisions quickly break down.
- Benchmarking mismatched metrics: Compare gross margin to gross margin, not contribution margin to gross margin.
- Ignoring other variable costs: If you subtract commission but ignore payment processing, rebates, freight, implementation, or channel fees, you may still overstate profitability.
- Using the wrong metric for the wrong decision: Gross margin is excellent for production economics; contribution margin is often better for pricing and sales management.
- Failing to document policy: Your finance manual and management reporting package should define each metric clearly.
A Practical Decision Framework
If you are unsure what to do, ask these questions:
- Is this number for audited statements, tax, lenders, or investors?
- Am I trying to evaluate the profitability of the product itself or the profitability of winning the sale?
- Does commission vary significantly by customer, channel, or rep?
- Will this metric be compared with outside benchmarks?
- Do decision-makers understand the difference between gross margin and contribution margin?
If the metric is external, benchmarked, or tied to standard reporting, exclude commission. If the metric is internal, tactical, and variable-cost focused, include commission in a separate contribution-style analysis.

Final Answer
So, should you include sales commission before calculating gross margin? Usually no, if you mean standard gross margin. Sales commission is generally treated as a selling expense and placed below gross profit. But yes, sometimes, if you are building an internal profitability metric that reflects variable selling cost. In that case, the clearer term is usually contribution margin or commission-adjusted margin rather than gross margin.
The most effective finance teams do not force one number to do every job. They preserve standard gross margin for comparability and external reporting, then add a second layer that subtracts commission for internal sales and pricing decisions. That approach gives you clean accounting, better unit economics, and fewer arguments in the next management meeting.
