What is Net Profit Margin?
Net Profit Margin is a key financial metric that measures the percentage of revenue that remains as profit after all expenses have been deducted. It represents the ultimate measure of a company's profitability, showing how much of every dollar earned translates into actual profit.
Unlike gross margin or operating margin, net profit margin accounts for ALL costs including cost of goods sold, operating expenses, interest, taxes, and any other expenses. This makes it the most comprehensive profitability ratio for assessing a company's financial health.
Net Profit Margin = (Net Profit / Total Revenue) × 100
Where:
Net Profit = Total Revenue - All Expenses
Understanding the Components
Total Revenue
Total revenue (also called gross revenue or sales) represents all income generated from a company's primary business activities before any deductions. This includes:
- Product sales
- Service fees
- Subscription revenue
- Licensing income
Net Profit
Net profit (also called net income or the "bottom line") is what remains after deducting all expenses from revenue:
- Revenue
- − Cost of Goods Sold (COGS)
- = Gross Profit
- − Operating Expenses
- = Operating Income (EBIT)
- − Interest Expense
- + Other Income
- − Taxes
- = Net Profit
How to Calculate Net Profit Margin
- Determine Total Revenue: Sum all sales and income for the period
- Calculate All Expenses: Add up COGS, operating expenses, interest, and taxes
- Find Net Profit: Subtract total expenses from revenue
- Calculate the Margin: Divide net profit by revenue and multiply by 100
Example Calculation
Consider a company with the following financials:
| Total Revenue | $500,000 |
| Cost of Goods Sold | ($200,000) |
| Gross Profit | $300,000 |
| Operating Expenses | ($216,000) |
| Operating Income | $84,000 |
| Interest Expense | ($8,000) |
| Other Income | $2,000 |
| Income Before Taxes | $78,000 |
| Income Taxes | ($28,000) |
| Net Profit | $50,000 |
Interpreting Net Profit Margin
Indicates strong profitability and efficient cost management. The company retains a significant portion of revenue as profit.
Falls within a typical range for many industries. May indicate room for improvement through cost reduction or pricing strategies.
Signals potential profitability issues. A negative margin means the company is losing money on every dollar of revenue.

| Operating Margin | Operational efficiency | Operating Income / Revenue |
| Net Profit Margin | Overall profitability | Net Profit / Revenue |
