What is Profit Margin? Simple explanation

Q: What is Profit Margin?

The percentage of revenue that remains as profit after deducting all costs and expenses of a business.

What is Profit Margin?

Profit margin is what’s left over from each dollar that comes in. If a company bills $100 and has $80 in costs, its profit margin is 20%. The larger the margin, the more efficient the business is.

Types of Margin

Gross Margin

(Revenue - Cost of Products) ÷ Revenue × 100
Shows efficiency in production/purchase

Operating Margin

(Revenue - Costs - Operating Expenses) ÷ Revenue × 100
Shows efficiency of operation

Net Margin

Net Profit ÷ Revenue × 100
Shows how much is really left over at the end

Practical example (clothing store)

	Value	Margin
Billing	$10,000	-
Cost of clothes	$4,000	Gross: 60%
Expenses (rent, salaries)	$4,000	Operational: 20%
Taxes	$1,000	Net: 10%
Net Profit	$1,000

What it’s for (investor)

When analyzing stocks, the profit margin shows:

Companies with high margins have a competitive advantage
Increasing margins indicate improving efficiency
Very low margins indicate a fragile business

For personal finance

You also have a “margin”: how much is left over from your salary after all expenses. If you earn $1,000 and $200 is left over, your personal margin is 20%. The ideal is at least 20% (50-30-20 rule).
