Calculate Your Net Income Margin
Enter revenue and net income to calculate net profit margin. Net income can be negative if the business is operating at a loss.
What is net income margin?
Net income margin (also called net profit margin) measures how much profit a company keeps from each dollar of revenue after all expenses are paid. Those expenses include operating costs, interest, taxes, depreciation, and other costs.
This metric is one of the most practical ways to evaluate business profitability because it captures the final “bottom line.” A higher margin usually indicates stronger cost control and better financial efficiency, while a lower margin can signal tight profits or excessive spending.
Net income margin formula
Standard formula
Net Income Margin = (Net Income ÷ Revenue) × 100
- Net income: Profit left after all expenses
- Revenue: Total sales before expenses
- Result: A percentage showing how much profit is retained per dollar of sales
Example: If a company has $500,000 in revenue and $50,000 in net income, the margin is 10%. That means the company keeps 10 cents in profit for every $1 of revenue.

Why net income margin matters
Revenue growth is great, but it doesn’t guarantee financial health. A business can increase sales and still struggle if costs rise faster than income. Net income margin helps you focus on what actually remains after everything is paid.
- Tracks true profitability over time
- Helps compare performance against industry peers
- Supports pricing, expense, and budgeting decisions
- Gives investors and lenders a quick view of financial quality

Net income margin

What is a good net income margin?
There is no single “perfect” margin. Good margins vary by sector, business model, and scale. Capital-intensive industries may run lower margins, while software businesses may achieve much higher margins.
- Under 5%: Often considered low, may indicate tight profitability
- 5% to 10%: Solid in many industries
- 10% to 20%: Strong profitability for many businesses

Always benchmark against similar companies rather than using universal targets.
