What is Gross Margin? Calculation, Interpretation and Examples
Gross margin is one of the most critical indicators showing the fundamental profitability of a company's business model.
Gross margin (gross profit margin) is the percentage of sales revenue that remains after subtracting the direct costs of producing or delivering the product/service from sales revenue.
At its core, it answers the question:
"When I make a sale, what percentage is left after paying the direct product cost?"
How to Calculate Gross Margin?
First, let's clarify two concepts:
- Revenue (Sales): Sales income
- Cost of Goods Sold (COGS): Direct costs required to produce/supply/deliver the product
- Gross Profit: Revenue − COGS
Formula
Gross Margin (%) = (Gross Profit / Revenue) × 100
That is:
Gross Margin (%) = ((Revenue − COGS) / Revenue) × 100
Gross Margin Example (Simple)
Let's say:
- Revenue: $1,000,000
- COGS: $650,000
Gross profit: 1,000,000 − 650,000 = $350,000
Gross margin: 350,000 / 1,000,000 = 35%
✅ The company keeps $0.35 in gross profit from every $1 of sales after direct costs.
What Does COGS Include? (What It Doesn't?)
For accurate gross margin calculation, correctly categorizing COGS is critical.
What's Included in COGS (typically)
- Raw material / product cost (retail purchase cost)
- Direct labor in production
- Direct production energy / packaging
- Logistics (in some models, direct delivery cost)
- Software/SaaS: hosting, third-party API costs, per-customer infrastructure expenses
What's NOT Included in COGS (typically)
- Marketing ad expenses
- Sales team salaries (mostly OPEX in most companies)
- Office, rent, accounting, management expenses
- R&D (mostly)
- Financing costs (interest, etc.)
Note: Some line items vary by industry. But the logic is the same: Direct production/delivery costs that increase with sales typically go into COGS.
Why is Gross Margin Important?
Gross margin is one of the most fundamental metrics showing whether a company's core business model is profitable.
- Do you have pricing power?
- Is cost control good?
- Does profitability improve as you grow (economies of scale)?
- Do you have a competitive advantage?
Particularly, investors and managers look at this before evaluating growth:
"Is this business's unit profitability solid?"
The Difference Between "Gross Margin" and "Net Profit Margin"
- Gross margin: Percentage remaining after direct costs only
- Net profit margin (net profit margin): Percentage remaining after all expenses including marketing, sales, management, financing, and taxes
A company's gross margin can be high but net profit low (if it spends aggressively on marketing, for example).
Interpreting Gross Margin by Industry
The question "is gross margin good or bad?" depends on the industry:
Generally lower margins
Mid-level, may improve with scale
Generally higher margins (infrastructure costs are relatively low)
This is why when comparing, you need:
- Same industry
- Similar business model
- Similar geography
to compare.
How to Improve Gross Margin?
The basic ways to increase gross margin:
- Raise prices (value-based pricing, bundling, premium plans)
- Lower COGS (supplier negotiation, production optimization, waste reduction)
- Change product mix (feature high-margin products)
- Efficiency/automation (reduce direct labor and operations costs)
- Delivery/logistics optimization (especially effective in e-commerce)
Frequently Asked Questions
What should gross margin be?
There's no single right answer. Industry comparison is needed. Also, company size, brand strength, and competition intensity determine it.
Are gross margin and markup the same thing?
No.
- Markup typically says how much you add on top of cost: (Sales − Cost) / Cost
- Gross margin says the profit relative to sales: (Sales − Cost) / Sales
The two produce different results.
If gross profit margin is declining, what does it mean?
Usually signals:
- Price pressure due to discounts/competition
- Rising COGS (exchange rates, raw materials, logistics)
- Product mix shifting to lower-margin products
- Operational inefficiency
Conclusion: What is Gross Margin?
Gross margin (gross profit margin) is the ratio of profit remaining after direct costs are deducted from sales. It shows the "fundamental profitability" of the business model and is central to pricing, cost control, and growth strategy decisions.
Healthy gross margin is one of the most important indicators of sustainable growth and operational success.
