How to Calculate Profit Margin
Profit margin measures how much of each dollar of revenue a business keeps as profit. It is one of the most important metrics for evaluating business health.
Two types of margin:
- Gross Margin = (Revenue − COGS) / Revenue — only direct costs
- Net Margin = (Revenue − All Expenses) / Revenue — includes overhead, taxes, etc.
- Markup = (Revenue − Cost) / Cost × 100 — profit relative to cost, not price
Example: Revenue $100,000 − Cost $60,000 = Profit $40,000 → 40% margin, 66.7% markup

Frequently Asked Questions
What is profit margin?
Profit margin is the percentage of revenue that remains as profit after costs are deducted. A 40% profit margin means that for every dollar of revenue, $0.40 is profit. It is calculated as (Revenue − Cost) / Revenue × 100.
What is the difference between gross margin and net margin?
Gross margin only subtracts the direct cost of goods sold (COGS) from revenue. Net margin subtracts all expenses — including operating costs, taxes, interest, and overhead. Net margin is always lower than gross margin and gives the most complete picture of actual profitability.
How do you calculate profit margin?
Profit Margin = (Revenue − Cost) / Revenue × 100. For example, if revenue is $100,000 and cost is $60,000, the margin is ($100,000 − $60,000) / $100,000 × 100 = 40%.
What is a good profit margin?
It varies significantly by industry. Software companies often see 70–90% gross margins. Retail typically runs 25–50% gross. Restaurants average just 3–9% net margin. Any margin above your industry average is generally considered good. Improving margin over time is the key indicator of business health.
What is the difference between margin and markup?
Margin is profit as a percentage of the selling price (revenue). Markup is profit as a percentage of cost. Selling something for $100 that cost $60 gives a 40% margin but a 66.7% markup. Markup is always a higher number than margin for the same transaction.
How do I calculate revenue from margin and cost?
Revenue = Cost / (1 − Margin/100). For example, if cost is $60,000 and desired margin is 40%, revenue = $60,000 / (1 − 0.40) = $60,000 / 0.60 = $100,000.
