What Is Profit Margin? A Simple Guide for Small Businesses
Learn what profit margin means, why it matters for your business, and how to calculate it using a simple formula.
Profit margin is one of the most important financial metrics for any business. It tells you how much of your revenue is actual profit after accounting for costs.
What Is Profit Margin?
Profit margin is the percentage of revenue that remains as profit after all costs have been deducted. It measures how efficiently a business converts sales into profits.
Why Profit Margin Matters
Understanding your profit margin helps you:
- Set better prices — Know if your prices cover costs and generate enough profit.
- Compare performance — Track how your profitability changes over time.
- Make informed decisions — Decide whether to cut costs, raise prices, or change suppliers.
- Attract investors — A healthy margin signals a well-managed business.
Types of Profit Margin
Gross Profit Margin This measures profit after deducting the direct cost of goods sold (COGS). It shows how efficiently you produce or source your products.
Net Profit Margin This measures profit after deducting all expenses, including operating costs, taxes, and interest. It gives the most complete picture of profitability.
Example Calculation
If you sell a product for $100 and it costs you $60 to make:
- Profit = $100 − $60 = $40
- Profit Margin = $40 ÷ $100 × 100 = **40%**
This means 40 cents of every dollar earned is profit.
What Is a Good Profit Margin?
Profit margins vary by industry. A 10% net profit margin is generally considered average, while 20% or more is considered healthy. Service businesses often have higher margins than retail or manufacturing businesses.
