3. Use the result to decide whether to reprice, cut costs, or change your mix.
4. Validation: Use the same currency for all inputs. Values must be 0 or higher. If Revenue is 0, margin is undefined. A negative result indicates a loss after all expenses.

Understanding Your Result

Net Profit Margin (%) = (Net Profit ÷ Revenue) × 100.
Net Profit = Revenue − (COGS + Operating Expenses + Interest + Taxes).
This shows the percentage of revenue left after every major expense. Positive, rising net margin signals efficient operations and healthy pricing. Negative or falling margins indicate pressure in costs, price, or debt service.

Why Net Margin Matters?

It reflects true profitability, resilience, and capacity to reinvest in growth.

When to Use It?

• Monthly and quarterly close reviews to track profitability.
• Before large spend decisions such as hiring or tooling.
• While planning promotions or fee changes that affect revenue mix.
• During supplier negotiations and budget resets.
• To compare products, business units, or markets on a like for like basis.

Practical Examples

Example 1: Standard case

Revenue = ₹20,00,000
COGS = ₹12,00,000
Operating Expenses = ₹4,00,000
Interest = ₹50,000
Taxes = ₹1,50,000
Net Profit = 20,00,000 − (12,00,000 + 4,00,000 + 50,000 + 1,50,000) = ₹2,00,000

Net Profit Margin = (2,00,000 ÷ 20,00,000) × 100 = 10%

Interpretation: Ten percent of revenue remains as profit after all costs.

Example 2: Cost pressure scenario

Revenue = ₹9,00,000
COGS = ₹6,00,000
Operating Expenses = ₹2,40,000
Interest = ₹30,000
Taxes = ₹15,000
Net Profit = 9,00,000 − (6,00,000 + 2,40,000 + 30,000 + 15,000) = ₹15,000
Net Profit Margin = (15,000 ÷ 9,00,000) × 100 ≈ 1.67%

Interpretation: Very thin net margin suggests renegotiating COGS, trimming opex, or revisiting pricing.
