Profit Margin Explained — Formula, Types & Real Examples

Profit margin is one of the most important metrics in business. It tells you how much of every dollar in revenue you actually keep as profit. Learn the formula, the three types of margin, and how to benchmark yours against industry standards.

What Is Profit Margin?

Profit margin is the percentage of revenue that remains as profit after costs are deducted. A 20% profit margin means that for every $100 in sales, $20 is profit and $80 covers costs.

It's expressed as a percentage, making it easy to compare businesses of different sizes. A small business with $200K revenue and 30% margin is more efficient than a large company with $10M revenue and 5% margin.

The Three Types of Profit Margin

Gross Profit Margin

(Revenue − COGS) ÷ Revenue × 100

Measures how efficiently you produce or source your product. Excludes operating expenses, taxes, and interest.

Operating Profit Margin

(Revenue − COGS − Operating Expenses) ÷ Revenue × 100

Shows how profitable your core business operations are before financing costs and taxes.

Net Profit Margin

Net Profit ÷ Revenue × 100

The true bottom line — profit after ALL costs including taxes, interest, and one-time items.

How to Improve Your Profit Margin

Raise Prices

Even a 5–10% price increase with no volume loss dramatically improves margin. Test with a small segment first.

Cut COGS

Negotiate with suppliers, buy in bulk, or find alternative vendors. Every dollar saved in COGS goes straight to margin.

Eliminate Low-Margin Products

Focus on your highest-margin offerings. Dropping unprofitable SKUs often increases overall margin.

Automate Operations

Reducing labor costs through automation improves operating margin without affecting revenue.

Frequently Asked Questions

What is a good profit margin?

It depends on the industry. For retail, 5% net margin is acceptable. For software, 20%+ is expected. Always compare against your industry benchmark rather than a universal number.

Is gross margin or net margin more important?

Both matter for different reasons. Gross margin shows production efficiency. Net margin shows overall business health. Investors typically focus on net margin for valuation purposes.

Can profit margin be over 100%?

Net profit margin cannot exceed 100% (you can't profit more than your revenue). However, gross margin can theoretically approach 100% for pure digital products with near-zero COGS.

How does profit margin differ from markup?

Markup is calculated on cost: (Price − Cost) ÷ Cost × 100. Margin is calculated on revenue: (Price − Cost) ÷ Price × 100. A 50% markup equals a 33% margin.
