What Is a Profit Margin and How Do I Calculate It?
Profit margin is the percentage of your revenue that's actually profit after costs — it tells you how much of each dollar you keep. The basic formula is simple: profit divided by revenue, times 100. If you earn $10,000 and keep $2,000 after expenses, your profit margin is 20%. Margin matters more than raw revenue because a business can bring in a lot of money and still keep almost none of it. Knowing your margin is how you tell a healthy business from a merely busy one.
Here's how to calculate and use it.
The formula, plainly
Take your profit (revenue minus costs), divide by revenue, and multiply by 100 to get a percentage. You'll hear about gross margin (after the direct cost of what you sell) and net margin (after all expenses). Net margin is the truest picture of what your business keeps.
Why margin beats revenue as a signal
Revenue is what comes in; margin is what stays. The SBA's guidance on managing your finances stresses understanding your numbers, and margin is one of the most telling. A thin margin means small problems — a price cut, a cost bump — can wipe out your profit, so it directly shapes how you price.
Track it and improve it
Calculate margin regularly, not once a year. Free tools like SCORE's finance and cash-flow templates make it easier to see the numbers behind your margin. You improve margin two ways: raise price or value, or lower costs — and knowing your current margin tells you which lever to pull first.
Where the how comes in
Turning "I know the formula" into pricing and cost decisions that actually raise your margin is the real work. The Business Starter Program helps you understand your numbers and use them to build a business that keeps more of what it earns.

Frequently asked questions
What's a good profit margin for a small business?
It varies widely by industry, so compare to your field rather than a universal number. The key is knowing yours and watching the trend.
What's the difference between gross and net margin?
Gross margin is after the direct cost of goods or services; net margin is after all expenses. Net margin shows what you truly keep.
How often should I calculate my margin?
Regularly — monthly or quarterly. Frequent checks catch problems while you can still fix them.
Can a business have high revenue but low margin?
Absolutely. Plenty of busy businesses keep very little per dollar. Margin, not revenue, tells you if you're actually profitable.
