Understanding Profit Margin
Profit margin is one of the most important metrics in business. It tells you what percentage of your revenue is actual profit after costs. Whether you’re pricing products, evaluating a business, or tracking financial health, understanding margin is essential.
Margin vs Markup: What’s the Difference?
These two terms are often confused, but they measure different things:
- Profit Margin = Profit / Revenue × 100
- Markup = Profit / Cost × 100
For example, if you buy something for $40 and sell it for $100:
| Note | Result |
|---|---|
| cost = 40 | 40 |
| price = 100 | 100 |
| profit = price - cost | 60 |
| profit / price * 100 | 60 |
| profit / cost * 100 | 150 |
The same transaction gives a 60% margin but a 150% markup.
The Profit Margin Formula
Profit Margin = ((Revenue - Cost) / Revenue) × 100
Example: E-commerce Product
You sell handmade candles for $35 each. Materials and shipping cost $12 per unit.
| Note | Result |
|---|---|
| candle price = 35 | 35 |
| unit cost = 12 | 12 |
| profit = candle price - unit cost | 23 |
| profit / candle price * 100 | 65.71 |
Types of Profit Margin
| Type | Formula | What It Measures |
|---|---|---|
| Gross margin | (Revenue - COGS) / Revenue | Production efficiency |
| Operating margin | Operating income / Revenue | Operational efficiency |
| Net margin | Net income / Revenue | Overall profitability |
Setting Prices Using Margin
If you know your cost and target margin, you can calculate the selling price:
Price = Cost / (1 - Target Margin / 100)
For a $25 product with a target 40% margin:
Price = 25 / (1 - 0.40)
Price = 25 / 0.60
Price = $41.67

Frequently Asked Questions
What is the difference between margin and markup?
Margin is the percentage of the selling price that is profit (profit / revenue x 100). Markup is the percentage added to the cost (profit / cost x 100). The same transaction gives different numbers: selling a $40 item for $100 yields a 60% margin but a 150% markup. Margin is always lower than markup for the same transaction.
What is a good profit margin?
Good profit margins vary by industry. Retail typically sees 2-5% net margins, while software companies may achieve 20-40%. Gross margins are higher: 50%+ is common in services. Compare your margin to industry benchmarks rather than an absolute number.
How do I calculate selling price from a target margin?
Use the formula: Price = Cost / (1 - Target Margin / 100). For a $25 product with a target 40% margin: Price = $25 / (1 - 0.40) = $25 / 0.60 = $41.67. This ensures your margin is calculated on the final selling price, not the cost.
