Net Profit Margin

What is Net Profit Margin?

Net profit margin is a financial ratio that measures how much of a company’s revenue remains as profit after all expenses (including operating costs, interest, taxes, and other charges) have been deducted.

It expresses profitability as a percentage, helping businesses, investors, and analysts evaluate how efficiently a company converts revenue into actual profit. As one of the most important indicators of financial health, net profit margin highlights overall cost control, pricing strategy, and operational performance.

Key takeaways

• Bottom‑line profitability: Shows how much profit a company earns for every dollar of revenue.
• Comprehensive measure: Includes all expenses, unlike gross or operating margins.
• Indicator of efficiency: Reflects cost management, pricing power, and overall financial performance.
• Useful for comparisons: Helps assess performance across companies, industries, and time periods.
• Sensitive to one‑time items: Extraordinary gains/losses can distort the margin.

How net profit margin is calculated

Formula:

Net Profit Margin = (Net Income / Revenue) × 100

Example:

If a company earns $2 million in revenue and $300,000 in net income:
Net Profit Margin = (300,000 / 2,000,000) × 100 = 15%

Why net profit margin matters

For investors:
