Frequently Asked Questions
What is net profit margin?
Net profit margin is the percentage of revenue that becomes actual profit after ALL expenses—COGS, operating costs, interest, and taxes. Formula: Net Income / Revenue × 100. This is your "bottom line".
Why is net margin lower than gross margin?
Net margin deducts ALL costs (COGS + operating + interest + taxes), while gross margin only deducts COGS. The difference is your operating expenses. If net is much lower than gross, your overhead is high.
What factors reduce net profit margin?
High operating expenses (rent, salaries, marketing), interest on loans, inefficient operations, price competition, and high tax rates all eat into net margin.
Mastering Net Profit Margin
Understanding the Profit Waterfall
Revenue flows down through various cost layers:
**Revenue**: ₹100
↓ Minus COGS: ₹40
**Gross Profit**: ₹60 (60% Gross Margin)
↓ Minus Operating Expenses: ₹35
**Operating Profit**: ₹25 (25% Operating Margin)
↓ Minus Interest: ₹3
↓ Minus Taxes: ₹5.5
**Net Profit**: ₹16.5 (16.5% Net Margin)
Each layer shows where money is going. Low net margin could mean high COGS, high overhead, or high financing costs.
