What Is Net Profit Margin?

Net profit margin is the percentage of revenue that remains as profit after all expenses are paid. It is the ultimate measure of how much money your business keeps from each euro of sales and directly reflects overall business efficiency and profitability. A higher net profit margin means the business is converting more of its revenue into actual profit.

Net profit margin accounts for all costs: cost of goods sold, operating expenses, interest, taxes, and any other expense. This makes it more comprehensive than gross profit margin, which only considers production costs. For example, two businesses might have identical gross margins but very different net margins due to differences in operating expenses, tax rates, or financing costs.

Net profit margin varies widely by industry. Capital-intensive or highly competitive sectors like retail typically run on thin margins, while asset-light industries such as software often sustain much higher margins. Comparing your net margin to your industry average helps you gauge competitive performance and identify improvement opportunities.

Formula

Net Profit Margin = (Net Income ÷ Revenue) × 100%

Example

A software reseller has annual revenue of €500,000 and net income (profit after all expenses and taxes) of €50,000. Net profit margin = (€50,000 ÷ €500,000) × 100% = 10%. This means the business keeps 10 cents profit for every euro of sales.
