What is Profit Margin?
Profit margin is a measure of profitability expressed as a percentage. It shows how much of each dollar in revenue becomes profit. Higher margins indicate a more profitable business.
Types of Profit Margin
1. Gross Profit Margin
Measures profitability after direct production costs.
2. Net Profit Margin
Measures overall profitability after all expenses.
Calculating Profit Margin
Example:
You sell a product for $100, and it costs you $60 to make:
- Profit = $100 - $60 = $40
- Profit Margin = ($40 ÷ $100) × 100 = 40%
Markup vs Margin
These are NOT the same! Margin is based on selling price, markup is based on cost.
| Metric | Formula | Example |
|---|---|---|
| Margin | Profit ÷ Price × 100 | $40 ÷ $100 = 40% |
| Markup | Profit ÷ Cost × 100 | $40 ÷ $60 = 66.7% |
Margin to Markup Conversion
Margin = Markup ÷ (1 + Markup)
Industry Benchmarks

Frequently Asked Questions
How do I calculate profit margin?
Margin = (revenue − cost) ÷ revenue × 100. Selling for $100 something that cost $60 gives a $40 profit, which is 40 ÷ 100 × 100 = 40%.
What is the difference between gross and net margin?
Gross margin subtracts only the direct cost of the goods. Net margin subtracts every expense, including rent, salaries and tax, so it is always lower and shows what the business really keeps.
Is margin the same as markup?
No. Margin is profit as a share of the selling price; markup is profit as a share of the cost. The same $40 profit on a $100 sale is a 40% margin but a 66.7% markup.
