Net Profit Margin

Net Profit Margin (or Net Margin) is the most comprehensive profitability metric, showing what percentage of revenue translates into actual profit after ALL expenses, including taxes and interest.

Formula:

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

Example:

Component	Value
Revenue	$1,000,000
COGS	$600,000
Operating Expenses	$250,000
Interest Expense	$20,000
Taxes	$30,000
Net Income	$100,000
Net Margin	10%

What Reduces Net Margin (vs Operating Margin):

• Interest expense (debt costs)
• Income taxes
• One-time charges
• Non-operating gains/losses

Industry Benchmarks:

Industry	Typical Net Margin
Software	15-25%
Banking	20-30%
Pharma	15-20%
Retail	2-5%
Airlines	2-8%
Grocery	1-3%

Interpretation:

Net Margin	Implication
> 20%	Highly profitable business
10-20%	Healthy profitability
5-10%	Acceptable for competitive industries
< 5%	Thin margins, volume-dependent
