Gross Margin

profitability

The percentage of revenue remaining after subtracting the direct costs of producing goods or services (COGS). It measures production efficiency before operating expenses.

Definition

Gross margin is the first and most important profitability metric for any business. It tells you what percentage of each revenue dollar survives the direct cost of making or delivering your product. A 70% gross margin means $0.70 of every dollar is available to cover operating expenses, marketing, R&D, and profit. A 20% gross margin means only $0.20 is available.

Gross margin varies enormously by business model. Software companies typically have gross margins of 70-90% because the marginal cost of each additional user is minimal. Retail businesses operate at 25-50%. Restaurants average 60-70% on food but far less after labor and rent. Understanding your industry benchmark is essential for evaluating whether your margins are healthy.

Tracking gross margin trends over time is more valuable than any single snapshot. Declining gross margins may indicate rising material costs, pricing pressure from competitors, a shift toward lower-margin products, or inefficient production. Improving gross margins usually creates more value than cutting operating expenses because the gains compound across every unit sold.

Formula

Gross Margin = ((Revenue - COGS) / Revenue) x 100

Example

A SaaS company generates $500,000 in monthly revenue. Server costs, third-party APIs, and customer support (direct costs) total $75,000. Gross margin = ($500,000 - $75,000) / $500,000 x 100 = 85%.
