4. What Does the Net Profit Margin Indicate?

The Net Profit Margin is one of the most important profitability indicators. It tells you how much of every rupee of revenue a company actually keeps as profit after covering all expenses—including cost of goods sold, operating costs, interest, and taxes.
In other words, this ratio answers a fundamental question:
"After paying for everything—materials, salaries, rent, debt, and taxes—how much profit does the company actually keep?"

Net Profit Margin: The Formula

Net Profit Margin (%) = (Net Profit / Revenue) × 100

What Does It Show?

The Net Profit Margin measures the efficiency of a business in converting revenue into actual profit. It reflects the company's capability to control costs across production, operations, financing, and taxation.

Key Insights from Net Profit Margin
RangeMeaning
High Net MarginStrong cost control, efficient operations, and effective tax management.
Moderate Net MarginNormal for stable industries or companies with average pricing power.
Low Net MarginRising expenses, thin margins due to pricing pressure, inefficiencies.
Negative MarginThe company is making a net loss (not profitable).
Example Calculation

Let’s consider a company:

Net Profit Margin = (20,00,000 / 2,00,00,000) × 100 = 10%
This means the company keeps ₹10 as profit from every ₹100 it earns in sales.

Real-World Investor Uses

  1. Comparing Companies:
    An investor comparing two companies with similar revenues can use net margin to identify the more profitable one.

  2. Tracking Performance Over Time:
    If a company’s margin improves YoY, it may be controlling costs better or increasing pricing power.

  3. Valuation and Stock Screening:
    Consistently high margins may indicate a competitive moat or strong brand.

Example: Stock Decision Based on Margin

Let’s say you're comparing two companies:

MetricCompany ACompany B
Revenue₹500 Cr₹500 Cr
Net Profit₹75 Cr₹35 Cr
Net Margin15%7%

Even though both have equal revenue, Company A is more profitable, keeping over twice the profit as Company B.
