What is Gross Margin? Definition and Best Practices

Gross margin is the percentage of revenue remaining after subtracting the cost of goods sold. It measures how much money a business retains from each sale before accounting for operating expenses. For product businesses, gross margin is one of the primary indicators of pricing strength and production efficiency.

Gross margin is calculated by subtracting cost of goods sold from revenue, then dividing the result by revenue. The formula produces a percentage: if a product sells for $100 and costs $60 to produce and deliver, the gross margin is 40%. This percentage tells operators how much of each revenue dollar is available to cover overhead, sales, marketing, and profit.

What counts as cost of goods sold varies by business model, which affects gross margin comparability. Manufacturers typically include raw materials, direct labor, and manufacturing overhead. Consumer goods brands often include product cost, inbound freight, and packaging. Companies that include more costs in COGS report lower gross margins, even if the underlying economics are identical to competitors that classify some of those costs below the gross margin line.

Gross margin benchmarks vary significantly by industry and channel. A software company might target 70-80% gross margins, while a consumer goods brand selling through retail often operates at 40-55%. Understanding where your gross margin sits relative to industry norms helps operations leaders identify whether the issue is pricing, cost structure, or both.

Gross margin has two inputs: revenue and cost of goods sold. Revenue is the net amount received from customers after discounts, returns, and allowances. Cost of goods sold includes all costs directly tied to producing and delivering the product. For physical product businesses, this typically includes manufacturing or purchase cost, inbound freight, duties, and direct packaging costs.

Landed cost is a frequent addition to COGS for imported goods. It captures all costs to bring a product from the point of manufacture to the distribution center, including ocean freight, customs duties, port fees, and drayage. Companies that exclude landed cost from COGS overstate their gross margin relative to the true profitability of each unit.

Operations leaders use gross margin to evaluate individual SKUs, product lines, and channels. A product with a below-average gross margin may still be worth carrying if it drives volume in a high-margin channel or supports a retail relationship. A product that looks profitable in isolation may drag overall margin if its COGS is understated because landed costs are booked elsewhere.

Supplier negotiations directly affect gross margin. Reducing the unit cost of a key input, renegotiating inbound freight rates, or shifting from air to ocean freight on slow-moving SKUs all improve gross margin without changing the selling price. Operations teams that actively manage input costs are often more effective at protecting gross margin than those focused primarily on pricing.

Gross margin should be tracked at the SKU level, not just at the company level. Blended gross margin can mask significant variation across products. A company reporting 45% gross margin may have individual SKUs at 20% and others at 65%. SKU-level margin analysis tells operations teams which products to prioritize, which to reprice, and which to discontinue.

• Cost of Goods Sold (COGS) is the direct cost input used to calculate gross margin, and how COGS is defined determines the accuracy of the gross margin figure.
• Landed Cost captures the full cost of bringing a product to your distribution center, and including it in COGS gives a more accurate gross margin for imported goods.
• Inventory Turnover Ratio measures how quickly inventory sells relative to the cost of that inventory, and pairing it with gross margin reveals whether high-margin products are actually generating returns efficiently.
• Total Cost of Ownership (TCO) extends beyond gross margin to account for all costs associated with a product or supplier relationship, including returns, warranty, and logistics costs not captured in COGS.
