Gross margin, net margin, markup — these terms are often confused. Here's exactly how to calculate each one and what they tell you about your business.
Why Profit Margin Matters More Than Revenue
Revenue tells you how much business you're doing. Profit margin tells you whether that business is actually making you money.
A business with $500,000 revenue and 5% net margin makes $25,000 profit. A business with $100,000 revenue and 40% net margin makes $40,000 profit. The smaller revenue business is more profitable.
Understanding your margins — and how to improve them — is one of the most valuable financial skills a business owner can develop.
Three Types of Profit Margin
1. Gross Profit Margin
This measures profitability after deducting the direct costs of producing your goods or services (cost of goods sold / COGS).
Formula:
Gross Profit Margin = (Revenue − COGS) ÷ Revenue × 100
Example:
Revenue: $80,000
COGS (materials, direct labour): $32,000
Gross Profit: $48,000
Gross Margin: ($48,000 ÷ $80,000) × 100 = 60%
What this means: for every $1 of revenue, you keep $0.60 after covering your direct production costs.
2. Operating Profit Margin
This deducts operating expenses (rent, salaries, software, marketing) on top of COGS.
Formula:
Operating Margin = (Revenue − COGS − Operating Expenses) ÷ Revenue × 100
Example (continuing above):
Operating Expenses: $25,000
Operating Profit: $48,000 − $25,000 = $23,000
Operating Margin: ($23,000 ÷ $80,000) × 100 = 28.75%
3. Net Profit Margin
The bottom line — after all costs including tax, interest, and one-off items.
Formula:
Net Margin = Net Profit ÷ Revenue × 100
Example:
Tax + other: $5,000
Net Profit: $18,000
Net Margin: ($18,000 ÷ $80,000) × 100 = 22.5%
Profit Margin vs Markup: The Confusion
Many business owners confuse margin and markup. They're calculated differently and give different numbers even from the same data.
Markup = Profit ÷ Cost × 100
Margin = Profit ÷ Revenue × 100If something costs you $60 and you sell it for $100:
When someone says "we mark up 50%," they mean the selling price is 50% above cost. The margin on a 50% markup is 33.3%, not 50%.
This distinction matters when negotiating pricing, comparing to benchmarks, and setting targets.
What Is a Good Profit Margin?
It varies enormously by industry:
Software/SaaS: Net margins of 20–30%+ are common. Professional services (consulting, law, design): Gross margins 60–80%, net margins 20–40%. Retail: Gross margins 20–50%, net margins 2–8%. Restaurants: Net margins 3–9%. Manufacturing: Net margins 5–20% depending on product.
Compare your margins to industry benchmarks rather than arbitrary targets. What matters most is whether your margins are improving over time and whether they're sufficient to sustain and grow your business.
How to Improve Your Profit Margin
Increase prices. The most direct lever, and often underutilised. A 10% price increase on $100,000 revenue with no change in costs adds $10,000 straight to profit.
Reduce COGS. Better supplier terms, reduced waste, more efficient production.
Cut unnecessary operating expenses. Audit subscriptions and overheads annually.
Improve your sales mix. Focus on high-margin products or services. Not all revenue is equally profitable.
Track monthly. Margin trends are more useful than single-period snapshots. A declining margin over 6 months is a warning sign. An improving margin confirms your strategy is working.
