Profit Margin vs Gross Margin: What's the Difference?
Two of the most important profitability metrics in business — yet many people confuse them. Learn exactly how profit margin and gross margin differ, when to use each, and how to calculate them accurately.
Introduction
Profit margin and gross margin are two essential profitability metrics, but they measure different things. Understanding the difference is critical for accurate financial analysis, pricing decisions, and business performance evaluation.
In this guide, we’ll break down the key differences, show the formulas with examples, and explain when to use each metric.
What Is Gross Margin?
Gross margin measures profitability after subtracting the direct cost of goods sold (COGS) from revenue. It shows how efficiently a company produces or acquires its products.
Gross Margin % = (Revenue − Cost of Goods Sold) ÷ Revenue × 100
What Is Profit Margin?
Profit margin (also called net profit margin) measures overall profitability after all expenses have been deducted — not just cost of goods sold.
Profit Margin % = (Net Profit ÷ Revenue) × 100
Key Differences
| Aspect | Gross Margin | Profit Margin |
|---|---|---|
| Focus | Production efficiency | Overall profitability |
| What it excludes | Operating expenses, taxes, interest | None — includes all costs |
| Typical % range | Higher (30–70%) | Lower (5–25%) |
When to Use Each Metric
Use Gross Margin when evaluating production costs, supplier negotiations, or pricing strategy for individual products.
Use Profit Margin when assessing overall business health, comparing companies, or making strategic decisions.
Worked Example
A business has £100,000 revenue, £40,000 COGS, and £35,000 operating expenses.
- Gross Profit = £60,000 → Gross Margin = 60%
- Net Profit = £25,000 → Profit Margin = 25%
Conclusion
Gross margin tells you how efficiently you produce goods. Profit margin tells you how profitable the entire business is. Both are important, but they serve different purposes.

Frequently Asked Questions
