Profit Margin Calculator: Gross & Net Margin
Calculate gross profit margin and net profit margin from revenue, COGS, and operating expenses. Free business profitability analysis tool.
What Is the Profit Margin Calculator?
The Profit Margin Calculator computes two core business profitability metrics: gross profit margin (revenue minus cost of goods sold, as a margin percentage of revenue) and net profit margin (revenue minus all expenses, as a percentage of revenue). Use it as a gross margin calculator, a business profit calculator, or both. These metrics are foundational to financial analysis, business planning, pricing decisions, and investor communication.
Key Features
- Calculate gross profit and gross margin %: the first line of profitability analysis.
- Calculate net profit and net margin %: the bottom-line profitability measure.
- Supports revenue, COGS, and operating expenses: all three main P&L line items.
- Instant business profitability analysis: suitable for any business size.
How to Use the Profit Margin Calculator
Step 1: Enter Revenue
Total revenue (or net sales) for the period. This is the top-line figure before any deductions.
Step 2: Enter Cost of Goods Sold (COGS)
Direct costs attributable to producing goods or delivering services sold: materials, direct labor, manufacturing overhead. Do not include selling, general and administrative (SG&A) expenses in COGS.
Step 3: Enter Operating Expenses
Selling, general and administrative expenses (SG&A), research and development, depreciation, and any other operating costs not included in COGS.
Practical Examples
Example 1: Retail business
Revenue: $500,000. COGS: $300,000. Operating expenses: $120,000.
Gross profit: $200,000. Gross margin: 40%. Net profit: $80,000. Net margin: 16%.
Example 2: Software company (high margin)
Revenue: $2,000,000. COGS: $200,000 (hosting, support). Operating expenses: $800,000 (salaries, marketing).
Gross margin: 90%. Net margin: 50%. Net profit: $1,000,000.
Example 3: Restaurant (thin margin)
Revenue: $600,000. COGS: $210,000 (food cost). Operating expenses: $330,000 (labor, rent).
Gross margin: 65%. Net margin: 10%. Net profit: $60,000.
Tips and Best Practices
Gross margin tells you about pricing and cost structure. A declining gross margin over time signals either rising input costs or competitive pricing pressure. Monitor it closely relative to competitors.
Net margin reveals operational efficiency. High gross margins combined with low net margins indicate excessive overhead. Identify the largest operating expense categories and evaluate whether they drive commensurate revenue.
Industry benchmarks vary widely. Grocery: 1%–3% net margin. Software: 15%–40%. Pharmaceuticals: 15%–25%. Restaurants: 3%–9%. Always compare to industry peers, not absolute targets.
Use margin, not absolute dollars, for trend analysis. A business that doubles revenue but keeps the same absolute net profit has seen its net margin cut in half, a warning sign even though total profit looks stable.
Price increases improve margins faster than cost cuts at the same scale. A 1% price increase on $1 million revenue adds $10,000 directly to profit (assuming constant volume). A 1% cost cut on $600,000 of costs adds $6,000. Pricing power is the most effective margin lever.
Common Issues and Troubleshooting
Net profit is negative. Your operating expenses exceed gross profit. This is sustainable short-term (during growth phases) but requires a clear path to profitability. Identify which expense line is largest and evaluate its necessity.
Gross margin is negative. This means COGS exceeds revenue, so you are selling below cost. This is rarely intentional and usually indicates a pricing or accounting error. Verify COGS includes only direct production costs.

Frequently Asked Questions
What is a good profit margin? "Good" depends entirely on industry. SaaS companies target 20%–40% net margins. Manufacturing might target 5%–10%. Retail grocery might be profitable at 2%–3%. Always benchmark against industry comparables.
What is the difference between gross margin and contribution margin? Gross margin deducts COGS from revenue. Contribution margin deducts only variable costs from revenue; it excludes fixed manufacturing overhead that gets included in COGS under absorption accounting. Contribution margin is used in break-even analysis.
Can I use this calculator for a service business? Yes. For service businesses, COGS typically includes direct labor costs for service delivery (consultant salaries, technician wages) rather than physical materials.
