Profitability
Who earns — and how much
What to learn
Reading revenue, profit, and margin together — not in isolation.
- Revenue giants ≈ $400–600B
- Retail margins ~2–5% vs. software margins ~25–35%
- Double-digit YoY growth (>15–20%) reads as strong
The tell
Always check margin alongside revenue size — a huge top line can still carry a thin (or negative) profit.
Common misconception
Assuming high revenue automatically means high profit.
Reading revenue and margin together
Company A reports $500B in revenue with a 3% net margin. Company B reports $40B in revenue with a 28% net margin. Which one is more profitable in dollar terms?
- Convert each to dollar profit: Company A ≈ $500B × 3% = $15B net income.
- Company B ≈ $40B × 28% ≈ $11.2B net income.
- Despite Company B's much higher margin, Company A's revenue scale gives it slightly more absolute profit.
A huge top line with a thin margin can still out-earn a smaller company with a fat margin — always multiply revenue by margin before comparing.
