Profit Margin

Net income divided by revenue as a percentage.

Profit margin (net profit margin) shows what percentage of revenue translates into actual profit after all expenses, taxes, and costs are subtracted. It's the bottom-line efficiency metric. Average net margins vary by industry—professional services may achieve 15–25%, while restaurants often operate at 3–9%. Improving profit margin requires either increasing revenue without proportional cost increases or cutting costs.

Formula

Profit Margin = (Net Income ÷ Revenue) × 100

Example

A consulting firm earns $400,000 in revenue with $340,000 in total expenses (including taxes), yielding $60,000 net income and a 15% profit margin.

Why It Matters for Your Business

Profit margin tells you how much of every dollar you keep—even high-revenue businesses can struggle if margins are razor-thin.
