Common Questions

Profit Margin FAQ

How do you calculate profit margin?

Subtract cost from revenue to get gross profit, then divide by revenue and multiply by 100. For example, $80 revenue minus $50 cost is $30 profit; $30 ÷ $80 = 37.5 percent margin. This calculator does it instantly and also shows the equivalent markup.

What is a good profit margin?

It varies by industry. As a rough guide, a 10 percent net margin is considered average, 20 percent is healthy, and 5 percent is low. Gross margins (what this tool calculates) run much higher because they exclude overhead. Compare against typical margins in your specific industry.

What is the difference between gross and net margin?

Gross margin counts only the direct cost of the product or service. Net margin also subtracts all other expenses — rent, payroll, marketing, taxes — to show what you actually keep. This tool calculates gross margin, which is the right starting point for pricing decisions.

Is this calculator free and private?

Yes. It is completely free, requires no signup, and runs entirely in your browser so your numbers never leave your device.
