Three margins, three stories
Profit isn't a single number — it's a cascade. Gross margin tells you how efficiently you produce what you sell. Operating margin tells you how well you run the business. Net margin tells you what's actually left for shareholders after everything — including taxes and interest — is paid.
What each margin reveals
- High gross, low operating: Production is efficient, but overhead is bloated. Cut SG&A.
- Low gross, high operating: Production is expensive, but you're running lean. Negotiate supplier costs or raise prices.
- High operating, low net: The business works, but debt service or taxes are crushing it. Restructure debt.
Benchmark margins by industry
- Software / SaaS: 70–80% gross, 20–40% net
- Restaurants: 60–70% gross, 3–9% net
- Retail: 30–50% gross, 2–6% net
- Manufacturing: 25–35% gross, 5–10% net
- Consulting / services: 50–70% gross, 10–20% net
Profit margin is a percentage, not a dollar amount. A 2% margin on $100M revenue ($2M profit) is more profit than a 30% margin on $5M revenue ($1.5M profit) — but the higher-margin business is more defensible against price competition.
Frequently asked questions
What is a good profit margin?
It depends on the industry. Software/SaaS: 20-40% net. Restaurants: 3-9% net. Retail: 2-6% net. Manufacturing: 5-10% net. Consulting: 10-20% net. Compare to your industry average — being above average is good; below average signals a problem.
What is the difference between gross and net margin?
Gross margin = (revenue − COGS) ÷ revenue. Net margin = (revenue − ALL expenses) ÷ revenue. Gross shows production efficiency; net shows overall business profitability. A company can have high gross margin but low net margin if overhead is bloated.
Why is my gross margin high but net margin low?
Common causes: (1) high SG&A (sales, general, administrative) expenses, (2) high rent or salaries, (3) significant debt interest, (4) high tax burden, (5) one-time expenses. Review your income statement line by line to identify the bleed.
Should I prioritize margin or revenue growth?
Both matter, but margin is more sustainable. A common mistake: chasing revenue growth at the expense of margin (discounting, low-margin product lines, expensive customer acquisition). Rule of 40 (SaaS): revenue growth rate + profit margin should equal 40+. Below 40 = underperforming.
How do I improve my profit margin?
Three levers: (1) raise prices (test elasticity — many businesses underprice), (2) reduce COGS (negotiate suppliers, improve processes), (3) cut operating expenses (audit SG&A, automate, outsource). The fastest is usually price increases; the most sustainable is COGS reduction.
What is contribution margin?
Price per unit minus variable cost per unit. The amount each sale 'contributes' toward fixed costs and profit. Used in break-even analysis. A $75 product with $32 variable cost has $43 contribution margin.
Is a 10% net margin good?
For most industries, yes — 10% net margin is above average. For software/SaaS, 10% is mediocre (should be 20%+). For restaurants, 10% is exceptional. For retail, 10% is exceptional. Always compare to your specific industry benchmark.
Glossary of key terms
- Gross Profit
- Revenue minus Cost of Goods Sold (COGS). Shows production efficiency.
- Operating Profit
- Gross profit minus operating expenses (SG&A). Shows business operations profitability.
- Net Profit
- Operating profit minus taxes and interest. What's left for shareholders.
- COGS (Cost of Goods Sold)
- Direct costs of producing goods/services: materials, direct labor, manufacturing overhead.
- SG&A (Sales, General, Administrative)
- Operating expenses not directly tied to production: salaries, rent, marketing, insurance.
Common mistakes to avoid
- Confusing markup with margin — 50% markup = 33% margin, not 50%
- Not tracking margins by product line — some products may be losing money
- Ignoring industry benchmarks — 5% net margin is great for grocery, terrible for software
- Discounting to grow revenue without calculating margin impact
- Not factoring in owner's compensation — many 'profitable' small businesses underpay the owner
Pro tips
- Track margins by product line — some products may be subsidizing others.
- Compare to industry benchmarks — public companies' financials are free on SEC EDGAR.
- Test price increases — many businesses underprice. A 10% price increase with 30% gross margin requires only 25% volume loss to break even.
- Audit SG&A annually — recurring subscriptions and 'zombie' expenses accumulate over time.
- Calculate 'contribution margin' per product — focus sales effort on highest-contribution items.
