Key takeaways
- Net profit margin shows what percentage of revenue your business keeps as profit after paying all expenses, including operating costs, interest and taxes.
- You calculate net profit margin by dividing net profit by revenue, then multiplying by 100 to get a percentage.
- A higher net profit margin means your business is more efficient at converting revenue into actual profit.

What is net profit margin?
Net profit margin is net profit divided by revenue, multiplied by 100. It shows what portion of revenue your business keeps as profit after all expenses.
This percentage is one of the clearest indicators of your business's overall financial health. While revenue tells you how much money comes in, net profit margin reveals how much you actually keep. A business with €500,000 in revenue might seem successful, but if only 2% remains as profit, there's little room for growth or unexpected costs.

Net profit margin formula
The formula for net profit margin is straightforward.
Net profit margin = (net profit ÷ revenue) × 100
Here's what each part means:
- Net profit: the amount left after subtracting all business expenses from revenue, including cost of goods sold, operating expenses, interest and taxes
- Revenue: the total income your business earns from sales before any deductions
How to calculate net profit margin
To calculate your net profit margin, you need your total revenue and net profit figures from the same period. Here's a worked example using a cleaning business.
Suppose your cleaning business earns €20,000 in revenue for the month. Your cost of services is €8,000, giving you a gross profit of €12,000. From this, you pay €3,000 in operating expenses and €4,000 in taxes, totalling €7,000. Your net profit is €12,000 minus €7,000, which equals €5,000.
Now apply the formula:
Net profit margin = €5,000 ÷ €20,000 × 100 = 25%
This means your business keeps €0.25 of every euro earned as profit.
How to interpret your net profit margin
Your net profit margin tells you how efficiently your business converts revenue into profit. A 25% margin, for example, means you keep €0.25 of every €1 of revenue after covering all costs.
A rising margin over time suggests your business is becoming more efficient, whether through better pricing, lower costs or increased sales volume. A falling margin might signal rising expenses, pricing pressure or operational issues that need attention.
What is a good net profit margin?
What counts as a good net profit margin depends on your industry, business model and stage of growth. However, a common rule of thumb suggests that around 5% is considered low, 10% is healthy and 20% or above is high.
Service businesses, such as consultancies or cleaning companies, often run higher margins because they have lower material costs. Retail or hospitality businesses typically operate on thinner margins due to higher overheads and cost of goods sold. The key is to compare your margin against similar businesses in your sector and track how it changes over time. Use benchmarks to measure profitability and identify areas for improvement.
Net profit margin vs gross and operating profit margin
Gross profit margin, operating profit margin and net profit margin each measure profitability at a different stage of your business's finances. Understanding the distinction helps you pinpoint where money is being made or lost.
- Gross profit margin: calculated as gross profit divided by revenue, multiplied by 100. Gross profit equals revenue minus cost of goods sold. This margin shows how efficiently you produce or deliver your product or service.
- Operating profit margin: calculated as operating profit divided by revenue, multiplied by 100. Operating profit equals gross profit minus operating expenses, but before deducting interest and taxes. This margin reflects the profitability of your core business operations.
- Net profit margin: calculated as net profit divided by revenue, multiplied by 100. Net profit equals revenue minus all expenses, including cost of goods sold, operating expenses, interest and taxes. This margin shows your overall profitability after everything is paid.
In short, gross margin looks at production efficiency, operating margin examines operational efficiency, and net margin reveals the bottom line.
