What Is a Profit Margin?

Profit Margin Definition

Profit margin measures how much money your business keeps as profit after paying for all expenses. It’s typically shown as a percentage of your total revenue.

Here’s the basic formula:

Profit Margin = (Net Profit ÷ Revenue) × 100

In plain English, if your business makes $100,000 in sales and keeps $20,000 after expenses, your profit margin is 20%.

2. Why Profit Margin Matters to Small Business Owners

Profit margin is one of the most important indicators of financial health and pricing strategy.

• It tells you how efficiently your business operates—whether your pricing covers not only costs but also generates a sustainable return.

• It helps you compare performance over time or against competitors.

• Lenders and investors often use it to evaluate your business’s stability and risk.

• A healthy profit margin gives you room to reinvest in growth, handle slow seasons, or withstand economic downturns.
  

In short, profit margin shows whether you’re running a thriving business or just staying busy.

3. Common Examples or Use Cases

There are a few types of profit margins you’ll encounter:

• Gross Profit Margin – Revenue minus the cost of goods sold (COGS). It shows how efficiently you produce or deliver your product.

• Operating Profit Margin – Reflects profit after accounting for overhead like payroll, rent, and marketing.

• Net Profit Margin – The “bottom line” after all expenses, interest, and taxes.

Example: If you sell coffee for $5 and it costs $2 in ingredients, your gross profit margin is 60%.After rent, payroll, and utilities, your net profit margin might drop to 10%.

4. Related Terms or Misconceptions

Profit vs. Cash Flow

• Profit margin shows how much you earn, but cash flow shows when you get paid. A business can be profitable on paper and still struggle with cash shortages.
  

Revenue vs. Profit

• Revenue is your total income. Profit is what’s left after expenses.
  

Markup vs. Margin

• Markup is the percentage added to cost to determine price.

• Margin is the percentage of sales that becomes profit. They’re related but not the same—confusing the two can lead to poor pricing strategy decisions.
