What Is Gross Margin?

How Gross Margin Is Calculated

Gross Margin = (Revenue − Cost of Goods Sold) ÷ Revenue × 100%. COGS includes direct production inputs: raw materials, manufacturing labour, and direct overhead. It excludes indirect costs like headquarters rent, executive salaries, or marketing spend (those appear below gross profit in the income statement). Software companies can reach 70–80%+ gross margins because their marginal cost to serve an additional customer approaches zero. Physical goods manufacturers typically see 20–50%. Grocery retail is often below 25%.

Why Gross Margin Reveals Competitive Moat

A high and stable or expanding gross margin is strong evidence of pricing power — the ability to charge more than competitors without losing customers. Apple's hardware gross margins have expanded from 37% to over 46% over a decade as its brand premium and ecosystem lock-in have strengthened. When gross margins compress over multiple quarters, it often signals competitive pressure — rivals are forcing price cuts, or input costs are rising faster than prices can be raised. Persistent margin compression is a key early warning of business deterioration.

Gross Margin vs Operating Margin vs Net Margin

These three margins measure different levels of the income statement:

• Gross margin — revenue minus direct production costs; measures production efficiency and pricing power
• Operating margin — gross profit minus operating expenses (R&D, S&M, G&A); measures overall business efficiency
• Net margin — operating profit minus interest, taxes, and one-times; measures final bottom-line profitability
• A company can have a high gross margin but a poor operating margin if it spends heavily on R&D or sales (common in early-stage tech). The trajectory of each margin over time is as important as the absolute level.

Gross Margin in GlobalTrack's Factor Model

GlobalTrack tracks gross margin trend as part of its Quality factor — one of the five factors in the proprietary factor ranking system. A company with expanding gross margins over 4 consecutive quarters scores higher on the Quality factor than one with contracting margins. Gross margin trend, combined with FCF stability and revenue growth trajectory, gives a comprehensive picture of business quality that is more forward-looking than backward-looking volatility metrics.
