Profit Margins

Metrics showing what percentage of revenue translates into profit at various levels.

What Are Profit Margins?

Profit margins measure how much of every dollar of revenue a company keeps as profit. There are three main types, each revealing different aspects of a company's financial health:

The Three Types

  • Gross Margin: (Revenue - Cost of Goods Sold) ÷ Revenue. Shows efficiency of production/service delivery. A software company might have 80% gross margins; a grocery store might have 25%.
  • Operating Margin: Operating Income ÷ Revenue. Includes all operating expenses (sales, R&D, admin). This shows how efficiently the company runs its core business.
  • Net Margin: Net Income ÷ Revenue. The bottom line after everything — interest, taxes, and all expenses. This is what ultimately accrues to shareholders.

Margin Trends Matter More Than Levels

While absolute margin levels vary dramatically by industry, the direction of margins is universally important. Expanding margins (especially operating margins) signal improving efficiency and pricing power. Contracting margins warn of rising costs, pricing pressure, or competitive threats.

Margins and Earnings Surprises

During earnings season, margin expansion is often the key driver of EPS beats. A company can beat EPS estimates even with in-line revenue if its margins expanded more than expected. This is why analysts focus heavily on margin guidance alongside revenue guidance.
