Should I Include Sales Commission Before Calculating Gross Margin?
Use this expert calculator to compare the standard gross margin view, which typically excludes sales commissions, against an adjusted profitability view that includes commissions as a selling cost. This helps finance teams, founders, and sales leaders avoid mixing gross margin with contribution margin.

Should You Include Sales Commission Before Calculating Gross Margin?
The short answer is usually no. In most financial reporting contexts, sales commissions are not included in gross margin. Gross margin is generally calculated as revenue minus cost of goods sold, or COGS. COGS covers the direct costs required to produce or deliver the product or service sold, such as materials, direct labor tied to production, freight-in, or certain direct fulfillment costs. Sales commission, by contrast, is commonly treated as a selling expense, meaning it sits below gross profit on the income statement rather than inside COGS.
That said, many operators still ask the question because they are trying to answer a different management problem: “After I pay the salesperson who generated the deal, how much money is left to cover overhead and profit?” That is a useful question, but the metric that answers it is usually not gross margin. It is more often contribution margin, channel margin, or deal-level profitability. Mixing the two can make reports inconsistent, confuse board presentations, and lead teams to compare unlike numbers across periods or business units.
What Gross Margin Is Actually Measuring
Gross margin is meant to show how efficiently the core product or service is produced and sold before overhead, administrative costs, and most selling expenses. It helps stakeholders answer questions like:
- How much profit is left after direct production or delivery costs?
- Is pricing strong enough relative to product or fulfillment cost?
- Are sourcing, labor, or fulfillment costs rising faster than revenue?
- How does product economics compare to industry peers?
If you put sales commission into gross margin, you change what the ratio is measuring. You no longer have a clean production or service delivery profitability metric. Instead, you now have a hybrid number that blends cost of sales execution with cost of product delivery. That may be useful for a special internal analysis, but it should not usually replace standard gross margin reporting.
Basic Formula
Standard gross margin is:
Gross Margin % = (Revenue – COGS) / Revenue
If a company also wants to see profitability after sales commission, it can calculate:
Contribution-Style Margin % = (Revenue – COGS – Sales Commission) / Revenue
Both metrics can coexist. The key is naming them correctly.
Why Sales Commission Is Usually Excluded
There are several practical and accounting reasons sales commission is usually excluded from gross margin:
- It is a selling expense, not a production cost. Commissions are generally incurred to acquire revenue, not to manufacture the item or fulfill the service.
- Comparability matters. Banks, investors, owners, and managers expect gross margin to be calculated consistently over time and benchmarked against peers.
- Operational accountability is clearer. Gross margin helps operations and finance teams evaluate sourcing, labor, and delivery efficiency without sales compensation distorting the view.
- Commission plans vary widely. Quotas, accelerators, split credits, bonuses, and territory adjustments can cause commission cost to swing for reasons unrelated to product economics.
When Businesses Still Analyze Commission Alongside Gross Margin
Even though commission is usually excluded from gross margin, it is often highly relevant for management decisions. For example, a founder may want to know if a discount-heavy deal is still worth closing once variable compensation is paid. A SaaS company may compare first-year contribution after commissions and implementation costs. A distributor may evaluate account-level profitability including account executive commissions, rebates, and shipping. These are valid analyses, but they should be labeled as contribution margin, variable margin, or fully loaded deal margin.
| Metric | Typical Formula | Usually Includes Commission? | Best Use |
|---|---|---|---|
| Gross Margin | (Revenue – COGS) / Revenue | No | Core product or service profitability |
| Contribution Margin | (Revenue – COGS – variable selling costs) / Revenue | Often yes | Deal, channel, or customer profitability |
| Operating Margin | Operating income / Revenue | Yes, through operating expenses | Overall business performance after selling and admin costs |
A Practical Example
Suppose your company closes a $100,000 sale. The direct cost to produce and deliver the order is $60,000. The salesperson earns an 8% commission, or $8,000.
- Standard gross profit: $100,000 – $60,000 = $40,000
- Standard gross margin: $40,000 / $100,000 = 40%
- Contribution after commission: $100,000 – $60,000 – $8,000 = $32,000
- Contribution-style margin: $32,000 / $100,000 = 32%
If you incorrectly included commission in gross margin, you might say gross margin is 32%. But that would not be apples-to-apples with prior periods, lenders, peers, or standard financial statements. The better presentation is: gross margin is 40%, and margin after variable sales compensation is 32%.
How Industry Practices Differ
Industry matters because the line between fulfillment cost and selling cost can be more complicated in some models. Service companies, agencies, and SaaS businesses often have unusual cost structures. But even then, the cleanest approach is to preserve standard gross margin for reporting and create a second metric for economics after commissions.
| Industry | Typical Gross Margin Range | Typical Sales Commission Range | Interpretation |
|---|---|---|---|
| Wholesale distribution | 20% to 30% | 2% to 10% of sales | Commission can materially change account profitability, but gross margin is still typically reported before commission. |
| Manufacturing | 25% to 40% | 3% to 8% of sales | Gross margin should isolate production efficiency; commissions belong in selling expense analysis. |
| SaaS | 70% to 85% | 8% to 15% of first-year contract value in many teams | Boards often monitor both gross margin and CAC-related metrics, which keeps commission outside gross margin but still highly visible. |
| Staffing / agency | 15% to 35% | 5% to 12% of gross profit or revenue depending on plan | Many firms maintain a spread or contribution metric after commissions while preserving standard gross margin conventions. |
The ranges above are broad directional benchmarks, not universal rules. The important point is that industries often monitor more than one profitability measure because a single margin number rarely tells the full story.
What Accounting Guidance and Reporting Norms Suggest
Public company reporting and standard financial statement presentation generally separate cost of sales from selling, general, and administrative costs. Sales commissions typically appear in SG&A or a similar operating expense category, unless a company uses a special internal format for management reporting. In other words, the formal question is often not “Can I include commission?” but “What metric am I trying to calculate?”
For businesses that capitalize certain contract acquisition costs under applicable accounting guidance, the treatment can become more nuanced on the balance sheet and through amortization. But that still does not automatically mean commission becomes part of gross margin. It simply means the company must follow the relevant accounting rules for recognition, capitalization, and amortization while keeping metric definitions consistent.
When Including Commission Can Be Useful Internally
There are valid reasons to run an “after commission” analysis. You may want that view when:
- Reviewing channel profitability by rep, partner, or territory
- Approving discounts or custom pricing
- Calculating account profitability for renewals
- Comparing direct sales vs partner sales
- Assessing first-year cash payback on new customer acquisition
- Setting minimum margin thresholds for custom quotes
In those cases, the issue is not that the analysis is wrong. The issue is naming. Use labels such as margin after commission, contribution margin, sales contribution, or deal-level profitability. That preserves decision usefulness without corrupting standard financial reporting.
Common Mistakes to Avoid
- Using the same term for two different formulas. If one report includes commission in “gross margin” and another excludes it, you will create confusion instantly.
- Mixing fixed and variable compensation carelessly. Base salary, bonuses, and commission may belong in different analytical buckets depending on purpose.
- Ignoring timing differences. Revenue may be recognized in one period while commission payout or accrual falls in another.
- Comparing across teams with different pay plans. One team may have high commissions and another may have higher base salaries, making “after commission” comparisons misleading if labor structures differ.
- Benchmarking against external companies using nonstandard definitions. Always confirm how peers define margin metrics.
A Good Reporting Framework for Most Businesses
If you want clarity, a layered approach works best:
- Revenue
- Less: COGS
- Equals: Gross profit and gross margin
- Less: Sales commissions and other variable selling costs
- Equals: Contribution margin or sales contribution
- Less: fixed operating expenses
- Equals: Operating income
This structure gives each team the right lens. Operations gets a clean gross margin measure. Sales leadership sees the economics after commissions. Executives and investors can trace the bridge from top-line revenue to operating income without ambiguity.

Final Verdict
In most cases, you should not include sales commission before calculating gross margin. Gross margin should normally reflect revenue minus COGS only. If you want to understand profitability after paying salespeople, calculate a separate metric such as contribution margin or margin after commission. Doing so keeps your accounting cleaner, your management reporting more useful, and your comparisons more credible.
So if your question is “Should I include sales commission before calculating gross margin?” the best expert answer is: usually no for standard gross margin, but yes as a separate internal profitability lens if you label it correctly.
