Think about it
Two companies have identical operating margins. One's net margin is half the other's. What happened in between?
Story
Let's picture it
Two identical bakeries earn ₹20 of operating profit on ₹100 of sales. One took a large loan to expand and pays ₹8 in interest. The other expanded slowly from its own savings. After tax, the first keeps about ₹9, the second about ₹15. The ovens are identical; the balance sheets are not.

From operating margin to net margin
Operating margin
Core business profitability
− Interest
Cost of debt
± Other income / one-offs
Non-core items
− Tax
Statutory obligation
= Net margin
The shareholder's final share
Plain English
The simple explanation
Net margin is net profit divided by revenue. It captures everything: operations, financing, tax and one-off items.
The gap between operating margin and net margin is the story. A wide gap usually means heavy interest costs, high tax, or reliance on non-operating income.
Because one-offs sit inside net profit, always recompute net margin excluding exceptional items before comparing across years.
Real world
HDFC Bank
For banks, margin analysis works differently, net interest margin matters more than a manufacturing-style net margin. This is a reminder that financial companies need their own toolkit, which is why analysts never apply one template to every sector.
Watch out
Common mistakes
- Comparing net margins without checking debt levels.
- Including one-off gains in trend analysis.
- Applying manufacturing margin logic to banks and NBFCs.
Did you know?
A company can have a positive net margin and negative cash flow in the same year, profit and cash are measured on different rules.
