Small business profit margin shows how much of every sales dollar your business keeps as profit. Two businesses can earn the same dollar profit and still be very different, because one may need far more sales to get there. Looking at your margins turns raw profit numbers into percentages you can track and compare over time.
This guide explains what profit margin is, the three main types, how to calculate each one, and how to improve your margins. It also includes a worked example with sample numbers.
What Is Small Business Profit Margin?
Profit margin is the percentage of your sales that remains as profit after costs are deducted. Each type of margin uses a different profit figure, but all of them divide that profit by revenue and multiply by 100.
For these calculations, revenue means net sales, which is sales after discounts, returns, and allowances.
Profit vs. Profit Margin
Profit is a dollar amount, such as $10,000. Profit margin is a percentage, such as 10%. The percentage tells you how much profit you make on each dollar of sales, which makes it easier to compare different months or years.
Why Small Business Profit Margin Matters
Tracking your margins helps in several ways:
- It shows what you keep from each sale. A net margin of 10% means you keep 10 cents of profit from every dollar of sales.
- It makes periods comparable. A margin shows whether profit is keeping pace with sales, even when your sales go up or down.
- It highlights trouble spots. Ratios do not prove a problem exists, but they point to areas worth reviewing.
- It supports decisions. You can see how pricing and cost changes affect what you keep.
The Three Types of Profit Margin
Gross Profit Margin
Gross profit margin shows what remains after the direct costs of making your product or delivering your service.
Gross profit margin = (Revenue − Cost of goods sold) ÷ Revenue × 100
Operating Profit Margin
Operating profit margin goes a step further. It subtracts operating expenses, which are the day-to-day costs of running the business, such as rent, staff, and marketing.
Operating profit margin = (Gross profit − Operating expenses) ÷ Revenue × 100
Net Profit Margin
Net profit margin shows what remains after all expenses, including interest and taxes. It is also called return on sales.
Net profit margin = Net profit ÷ Revenue × 100
How to Calculate Small Business Profit Margin
Follow these steps, using the figures from your profit and loss statemen:
- Find your revenue for the period.
- Calculate gross profit by subtracting cost of goods sold from revenue.
- Calculate operating profit by subtracting operating expenses from gross profit.
- Calculate net profit by subtracting interest, taxes, and any other remaining expenses from operating profit.
- Divide each profit figure by revenue and multiply by 100.
Small Business Profit Margin Example
Here is a simple example. These numbers are hypothetical.
- Revenue: $100,000
- Cost of goods sold: $60,000
- Operating expenses: $25,000
- Interest and taxes: $5,000
Gross profit: $100,000 − $60,000 = $40,000
Gross profit margin: $40,000 ÷ $100,000 × 100 = 40%
Operating profit: $40,000 − $25,000 = $15,000
Operating profit margin: $15,000 ÷ $100,000 × 100 = 15%
Net profit: $15,000 − $5,000 = $10,000
Net profit margin: $10,000 ÷ $100,000 × 100 = 10%
In this example, the business keeps 10 cents of net profit from every dollar of sales.
Margin vs. Markup
Margin and markup are not the same. Margin is profit divided by the selling price. Markup is profit divided by cost.
For example, suppose an item costs $60 and sells for $100. The profit is $40.
- Margin: $40 ÷ $100 = 40%
- Markup: $40 ÷ $60 = about 66.7%
The same $40 of profit produces two different percentages, so mixing them up can lead to pricing mistakes.
How to Improve Small Business Profit Margin
A margin improves when your costs fall or when your prices rise without hurting sales. There are three main levers.
Raise Your Prices
A higher price increases revenue without changing your costs. However, test price changes carefully, because a higher price may also affect demand. Our guide to break even analysis for small business shows how price changes affect the sales you need.
Reduce the Cost of Goods Sold
Lower direct costs raise your gross margin. Using the example above, if cost of goods sold falls from $60,000 to $55,000, gross profit rises to $45,000. The gross margin becomes 45%, and operating profit rises to $20,000, which is a 20% operating margin.
Reduce Operating Expenses
Lower running costs raise your operating margin. If operating expenses in the example fall by $3,000, operating profit becomes $18,000, which is an 18% operating margin. Our guide to small business expenses explains how to track and review your spending.
Interest and taxes depend on your situation, so changes in your costs will also affect your net margin.
How to Interpret Your Profit Margin
A margin is most useful when you compare it with something meaningful:
- Compare it with your own past results. Reviewing your margins over several periods helps you see whether they are improving or slipping.
- Be careful with industry comparisons. What counts as a good net margin differs quite a bit from one industry to another. For example, a grocery store usually has a very low net profit margin, while a jewelry store’s is typically higher.
- Remember that ratios use past data. They may not predict future results, and they point to possible problems rather than prove them.
For more detail on how these ratios are used, see this OpenStax Introduction to Business chapter on analyzing financial statements.
Common Profit Margin Mistakes
- Mixing up margin and markup. They use different denominators, so they give different percentages.
- Changing the revenue figure. Use the same definition of revenue each time so your results stay comparable.
- Looking at only one margin. Gross, operating, and net margins each show a different part of the picture.
- Comparing with a different type of business. Margins vary by industry, so comparisons work best between similar businesses.
- Confusing profit with cash. Margins come from your income statement and do not show when money comes in and goes out. See our guide to small business cash flow for that.
Frequently Asked Questions
What is a profit margin?
It is the percentage of sales that remains as profit after costs are deducted.
What is the difference between gross, operating, and net profit margin?
Gross margin subtracts only the direct costs of making a product or delivering a service. Operating margin also subtracts operating expenses. Net margin subtracts all expenses, including interest and taxes.
How do I calculate net profit margin?
Divide net profit by revenue and multiply by 100.
What is a good profit margin for a small business?
It depends on the industry. Compare your margin with your own past results and with similar businesses rather than relying on a single target.
What is the difference between margin and markup?
Margin is profit divided by the selling price. Markup is profit divided by cost.
How can I improve my profit margin?
You can raise prices, reduce the cost of goods sold, or reduce operating expenses. Each change affects your margins differently, so review the results after you make them. Planning ahead also helps, as explained in our guide to small business budgeting.
Conclusion
Small business profit margin turns your profit into a percentage you can track, compare, and improve. By calculating gross, operating, and net margins from your income statement, you can see where your profit is made and where it is lost. Review your margins regularly, compare them with your own history, and use them to guide your pricing and cost decisions.
