Profit Margin Calculator — Gross, Operating, and Net Margin Explained
Calculate gross, operating, and net profit margins for your business. Understand which costs are eating your revenue at each level of the P&L.
Revenue is vanity, profit is sanity — but even "profit" isn't one number. There's gross profit, operating profit, and net profit, and each one tells a different part of the story. The CalcHub Profit Margin Calculator calculates all three from your revenue and cost inputs, so you can pinpoint exactly where your margin is leaking.
The Three Margin Levels
Gross Margin = (Revenue − COGS) / Revenue × 100 Tells you: how efficiently do you deliver your product/service? Operating Margin = (Revenue − COGS − Operating Expenses) / Revenue × 100 Tells you: how well does the core business run before financing? Net Margin = Net Profit After Tax / Revenue × 100 Tells you: what actually stays in the business after everything?A Full P&L Example
A clothing brand with ₹50 lakhs in monthly revenue:
| Line Item | Amount | Margin |
|---|---|---|
| Revenue | ₹50,00,000 | 100% |
| COGS (fabric, manufacturing, freight) | ₹22,00,000 | − |
| Gross Profit | ₹28,00,000 | 56% |
| Operating Expenses (salaries, marketing, rent, SaaS) | ₹18,00,000 | − |
| Operating Profit (EBIT) | ₹10,00,000 | 20% |
| Interest on business loan | ₹1,00,000 | − |
| Tax (30% effective) | ₹2,70,000 | − |
| Net Profit | ₹6,30,000 | 12.6% |
Industry Margin Benchmarks
Margins vary wildly by industry. What's good in one sector is terrible in another:
| Industry | Typical Gross Margin | Typical Net Margin |
|---|---|---|
| Software / SaaS | 65–85% | 15–30% |
| E-commerce (branded) | 40–60% | 5–15% |
| Restaurant / F&B | 60–70% (food cost) | 3–9% |
| Manufacturing | 25–40% | 5–10% |
| Consulting / Services | 40–70% | 10–25% |
| Grocery / FMCG | 20–30% | 1–5% |

Where Margins Typically Leak
Gross margin erosion:- Rising raw material or supplier costs not passed to customers
- Higher returns or wastage rates
- Freight and logistics cost increases
- Headcount growing faster than revenue
- Marketing spend with declining efficiency
- SaaS tool sprawl — subscriptions nobody's reviewing
- Debt taken on for growth (interest expense)
- Tax surprises from complex structures
What's considered a healthy profit margin for a startup?
Most early-stage startups have negative or near-zero net margins — they're investing in growth. Gross margins are more important early: a SaaS startup with 70% gross margins and -30% net margins is in a very different position than a marketplace with 15% gross margins and -30% net. High gross margins signal that the unit economics can work; net margins improve as the company scales fixed costs over more revenue.
Gross margin vs gross profit — what's the difference?
Gross profit is the absolute rupee figure (Revenue − COGS). Gross margin is gross profit as a percentage of revenue. Both matter but serve different purposes: gross profit tells you the absolute value created per sale; gross margin tells you the efficiency of that creation regardless of scale.
Should I include depreciation in COGS or operating expenses?
Depreciation on production equipment (machinery, tools directly used in making the product) typically goes in COGS. Depreciation on office equipment, vehicles, and non-production assets goes in operating expenses. Getting this right affects gross vs operating margin comparisons — but doesn't change net profit or cash flow.
