Profit Margin
Last reviewed 2026-05-11 by Asad Ali, Founder & CEO
Net income divided by revenue, expressed as a percentage — the share of each revenue dollar kept as profit.
Profit margin shows what percentage of revenue translates into profit after a defined set of costs is subtracted. Three margins are tracked at different levels of the income statement: gross profit margin (revenue minus COGS, divided by revenue) measures core pricing and production efficiency; operating profit margin or EBIT margin (operating income divided by revenue) measures profitability after operating expenses but before interest and taxes; and net profit margin (net income divided by revenue) is the bottom-line efficiency metric after every cost, interest, and tax has been paid. The unqualified term "profit margin" almost always refers to net profit margin. Average margins vary enormously by industry — software and SaaS companies often achieve 15–30%+ net margin, professional services 10–20%, manufacturing 5–10%, restaurants 3–9%, and grocery stores 1–3%. Improving profit margin requires raising prices, growing revenue mix toward higher-margin offerings, reducing cost of goods sold, controlling operating expenses, or some combination. Margin trends matter at least as much as absolute levels — a steadily falling margin is an early warning sign even if the company is still profitable.
Formula
Net Profit Margin = (Net Income ÷ Revenue) × 100. Gross Profit Margin = (Gross Profit ÷ Revenue) × 100. Operating Profit Margin = (Operating Income ÷ Revenue) × 100.Example
A consulting firm earns $400,000 in annual revenue with $80,000 in direct project costs, $200,000 in operating expenses (salaries, rent, software, marketing), $10,000 in interest expense, and $50,000 in income tax — total expenses $340,000, net income $60,000. Gross profit margin = ($400,000 − $80,000) ÷ $400,000 = 80%. Operating profit margin = ($400,000 − $80,000 − $200,000) ÷ $400,000 = 30%. Net profit margin = $60,000 ÷ $400,000 = 15%. If the firm raises bill rates 10% with no cost change, revenue rises to $440,000, net income to $100,000 (after additional tax), and net margin jumps to roughly 23% — a 10% price increase translated into an 8-point margin gain.
Why It Matters for Your Business
Profit margin tells you how much of every revenue dollar you actually keep. High-revenue businesses with thin margins are fragile — a small cost increase or revenue dip wipes out profitability entirely.
Practical Tips
- •Track all three margins (gross, operating, net) trended monthly — a drop in gross margin points to pricing or production issues, while a drop in operating margin points to overhead creep
- •Benchmark against your industry, not against unrelated businesses — a 5% net margin is great in grocery and terrible in software
- •Watch margin compression as the earliest warning sign of competitive pressure — usually shows up 2–3 quarters before revenue growth slows
- •A 1-point margin improvement on $1M of revenue is $10,000 of pure profit and typically requires far less effort than chasing the equivalent in new sales
Common Questions About Profit Margin
How is profit margin calculated?
The formula is: Net Profit Margin = (Net Income ÷ Revenue) × 100. Gross Profit Margin = (Gross Profit ÷ Revenue) × 100. Operating Profit Margin = (Operating Income ÷ Revenue) × 100.. See the worked example below for a step-by-step calculation using realistic numbers.
What is an example of profit margin?
A consulting firm earns $400,000 in annual revenue with $80,000 in direct project costs, $200,000 in operating expenses (salaries, rent, software, marketing), $10,000 in interest expense, and $50,000 in income tax — total expenses $340,000, net income $60,000. Gross profit margin = ($400,000 − $80,000) ÷ $400,000 = 80%. Operating profit margin = ($400,000 − $80,000 − $200,000) ÷ $400,000 = 30%. Net profit margin = $60,000 ÷ $400,000 = 15%. If the firm raises bill rates 10% with no cost change, revenue rises to $440,000, net income to $100,000 (after additional tax), and net margin jumps to roughly 23% — a 10% price increase translated into an 8-point margin gain.
