Profitability metric

Gross Margin

Measures the percentage of revenue left after direct costs of producing goods or services.

Formula

Gross Margin = (Revenue - Cost of Revenue) / Revenue x 100%

Worked example$10 billion of revenue minus $6 billion of direct costs leaves $4 billion, producing a 40% gross margin.

Calculation steps

  1. Subtract $6 billion of cost of revenue from $10 billion of revenue.
  2. The result is $4 billion of gross profit.
  3. Divide $4 billion by $10 billion and multiply by 100 to get 40%.

How to interpret it

Rising gross margin can indicate pricing power, better product mix, or production efficiency; falling margin can flag cost or pricing pressure.

Industry context

Software, retail, manufacturing, and banking economics are structurally different. Compare margins within a relevant peer group.

Common mistakes

  • Confirm how the company classifies costs.
  • Do not confuse gross margin with gross profit.
  • Check whether acquisitions or product mix changed the comparison.
