- Gross Profit/Loss: Revenue (₹1,00,000) - Cost (₹70,000) = ₹30,000
- Profit Margin: (30000 ÷ 100000) × 100 = 30%
- Cost Share of Revenue: (70000 ÷ 100000) × 100 = 70%
- Equivalent Markup on Cost: (30000 ÷ 70000) × 100 = 42.86%
Understanding Commercial Profit Margin
Learn how to measure gross margin, optimize product unit economics, and avoid confusing margin with markup.
1. What is Gross Profit Margin?
Gross Profit Margin is a key financial ratio measuring the percentage of revenue remaining after subtracting direct costs (Cost of Goods Sold / COGS). It indicates how efficiently a business converts top-line sales into gross earnings to cover operating expenses and net profits.
2. Core Formulas
Gross Profit = Revenue - Cost
Profit Margin % = (Gross Profit ÷ Revenue) × 100
Where Revenue > 0.
3. Margin vs. Markup: The Crucial Difference
The most frequent mistake in business pricing is mixing up Margin and Markup. Although both use the same rupee profit, their denominators are completely different:
| Metric | Formula | Denominator | Example (Cost ₹70, Sell ₹100) |
|---|---|---|---|
| Profit Margin | (Profit ÷ Revenue) × 100 | Selling Price (₹100) | 30.00% |
| Markup | (Profit ÷ Cost) × 100 | Cost (₹70) | 42.86% |

- Cost Exceeding Revenue: If selling price is ₹70 while cost is ₹80, the business experiences a net loss of ₹10, resulting in a negative margin (-14.29%).
- Ignoring Indirect Overhead: Gross profit margin only reflects direct production costs. Rent, marketing, salaries, and interest must be covered by this margin before net profit is realized.
