Many small business owners are excellent at calculating their revenues to the dollar and can even approximately calculate their profit. Ask them about the gross margin, and many will give you an empty stare something only accountants and investors care about.
Gross margin is, in fact, one of the critical figures in a company’s income statement reflecting how much of the money from sales is left after direct costs incurring to actually produce or deliver a product or service sold. In other words, it is the amount of money the company has to pay for its rent, employees, advertising, and interest on loans taken, with profit being the final stage.
And when the gross margin decreases, which it regularly does, every item on the final P&L statement suffers, unless the owner hasn’t noticed it yet.
Gross profit and gross margin are essentially the same metric, with gross profit being the actual amount of money derived from sales and gross margin, the percentage that figure represents from the total revenue.
Gross profit and gross margin both measure how efficiently a business produces its goods or services but they express the same information differently. Gross profit is an absolute dollar figure; gross margin is a percentage. Understanding both helps you price correctly, benchmark against your industry, and identify where margin is leaking.
The most common way I see gross margin erode without anyone noticing is costs creeping up on products whose prices never changed. A supplier raises prices a few percent, shipping costs go up, a discount code runs longer than planned, and each change is too small to feel.
Revenue is growing, so the owner assumes things are fine, but gross margin has quietly dropped five points over a year. A simple monthly check catches it: compare gross margin with the same month last year, by product line if you can. A drop of more than a point or two deserves an explanation.

Gross Profit = Revenue − Cost of Goods Sold (COGS)
COGS includes all direct costs of producing the product or delivering the service: raw materials, direct labour, packaging, and direct production overhead. It does NOT include operating expenses like rent, marketing, salaries of non-production staff, or interest.
Example: Revenue $200,000 − COGS $120,000 = Gross Profit $80,000
What is Gross Margin?
Gross Margin (%) = (Gross Profit / Revenue) x 100
Using the same example: ($80,000 / $200,000) x 100 = 40% gross margin
Gross margin converts the dollar profit into a percentage, useful for comparing across periods, against competitors, or across product lines of different sizes.
Industry-Specific Gross Margin Benchmarks
What counts as a good gross margin varies enormously by sector:
| Industry | Typical Gross Margin Range | Key Driver |
|---|---|---|
| SaaS / Software (product) | 70 to 85% | Low marginal cost of delivering software; no physical COGS |
| Professional Services (consulting, legal, accounting) | 60 to 80% | Labour is COGS; depends on utilisation and billing rate |
| E-commerce (branded products) | 40 to 60% | Buying margin and fulfilment costs are the main levers |
| Manufacturing | 25 to 40% | Raw material and direct labour cost management |
| Retail (physical goods) | 25 to 50% | Varies by category, apparel higher, electronics lower |
| Restaurants | 60 to 70% | Gross margin is high; net margin is low due to labour/rent overhead |
| Construction / Project-Based | 15 to 30% | Labour and materials dominate; subcontractor cost management critical |
| Healthcare | 30 to 50% | Staffing is the primary COGS component |
Implication: A 40% gross margin is excellent for a manufacturer, adequate for an e-commerce business, and a warning sign for a SaaS company. Always benchmark against your own sector, not a generic number.
Gross Margin vs Gross Profit: Key Differences
| Gross Profit | Gross Margin | |
|---|---|---|
| Format | Dollar amount ($) | Percentage (%) |
| Formula | Revenue − COGS | (Gross Profit / Revenue) × 100 |
| Used for | Absolute profitability; trend tracking in $ terms | Comparison across periods, products, and competitors |
| Scale sensitivity | Grows with revenue | Stays constant if efficiency is maintained |
| Example | $80,000 | 40% |
Can a Business Have High Gross Profit but Low Gross Margin?
Yes and it is common in high-revenue, low-margin businesses. A retail chain doing $10M in revenue with 25% gross margin earns $2.5M gross profit. A boutique agency doing $500K revenue with 65% gross margin earns $325K gross profit. The chain has higher absolute gross profit but a structurally less efficient cost model small drops in revenue hit the bottom line harder.
What's the Difference Between Gross Margin and Profit Margin?
Gross margin stops at COGS, it does not deduct operating expenses, interest, or taxes. Profit margin (net margin) is after everything. A business with 60% gross margin but $200K in monthly overheads, $30K interest, and $20K taxes might end up with a 5% net margin. The gap between gross and net margin is where overhead, debt service, and tax efficiency matter.
CLIENT QUOTE
We thought our margins were healthy because we were looking at total sales and profit, but a closer review showed that several costs had been classified incorrectly and one of our product lines was barely profitable. Profitjets separated the COGS correctly and helped us review pricing and product-level margins, which showed us where we needed to raise prices and where we were spending more than the product was actually worth.

FAQs
Is gross margin the same as gross profit?
No, though they come from the same numbers. Gross profit is the dollar amount left after subtracting the cost of goods sold from revenue. Gross margin expresses that amount as a percentage of revenue.
What is a good gross margin?
It depends on your industry and your overhead. Software and service businesses usually run much higher gross margins than retailers, manufacturers, or construction companies. The practical test is whether your gross margin leaves enough to cover operating expenses and produce the profit you need, and whether it's holding steady over time.
How do you calculate gross margin?
Gross margin is calculated by subtracting the cost of goods sold (COGS) from revenue, then dividing the gross profit by revenue and multiplying by 100. For example, if a business generates $100,000 in revenue and has $60,000 in COGS, its gross profit is $40,000 and its gross margin is 40%.
Why is gross margin important for a business?
Gross margin shows how much revenue remains after covering the direct costs of producing or delivering goods and services. Tracking it over time can help businesses identify changes in pricing, direct costs, product mix, and overall profitability before those changes affect the bottom line.
What is the difference between gross margin and net margin?
Gross margin measures the revenue left after deducting the direct costs of goods or services sold, while net margin measures the profit remaining after all business expenses, including operating costs, interest, and taxes. Gross margin helps assess the profitability of the core offering, while net margin shows the overall profitability of the business.
