Understanding Profit Margins
Profit margin measures how much of every dollar of revenue becomes profit after expenses. It's one of the most important metrics for evaluating business health, comparing companies, and making strategic decisions.
There are three key margin types, each telling a different story about your business's financial performance.
The Three Key Margins
Gross Profit Margin
Gross Margin = (Revenue - COGS) / Revenue × 100
Measures production efficiency
Gross margin shows how efficiently you produce or source your products. A 40% gross margin means $0.40 of every $1 in revenue is available after covering direct production costs.
What's Included in COGS?
Operating Profit Margin
Operating Margin = (Gross Profit - Operating Expenses) / Revenue × 100
Measures operational efficiency
Operating margin shows how well you run day-to-day operations. It captures both production efficiency AND overhead management. Also called EBIT margin (Earnings Before Interest and Taxes).
Net Profit Margin
Net Margin = Net Profit / Revenue × 100
The bottom line
Net margin is the ultimate measure — what's left after every single expense. This is actual profit that can be reinvested, distributed to owners, or saved.

Interpreting Your Margins
Gross Margin Issues
Low gross margin typically indicates:
- Products priced too low

- Excessive discounting
Operating Margin Issues

- Overhead too high relative to revenue
- Too many employees for sales volume
- Expensive office/facility costs
- Marketing spending not generating returns
- Need to increase scale
Net Margin Issues
Low net margin (with healthy operating margin) points to:

Improving Your Margins
Short-Term Tactics

- Reduce discounting and promotions
- Improve inventory management
Long-Term Strategies
- Improve product mix toward higher-margin items

- Understand the relationship between all three margins
- Set margin targets and hold teams accountable
Frequently Asked Questions
Q: What's a good profit margin?
A: It depends heavily on industry. Generally, 10%+ net margin is good, 15%+ is excellent. But a 3% net margin in grocery is great while 10% in SaaS is concerning.
Q: Can margins be too high?
A: Potentially. Very high margins might mean you're underpricing (leaving money on the table) or you could reinvest more in growth. High margins also attract competition.
Q: Why do margins decrease as companies grow?
A: Not always, but often due to: price discounting for volume, entering less profitable segments, increased overhead, and competition forcing prices down.
Q: Should I focus on revenue or margin?
A: Both matter, but profit (the combination) is what counts. A 10% margin on $1M revenue ($100k profit) beats a 20% margin on $300k revenue ($60k profit).
Q: How do I calculate margins for a service business?
A: COGS for services typically includes direct labor costs and any materials/software used to deliver the service. Everything else is operating expense.
Q: What's the difference between margin and markup?
A: Margin is profit as % of selling price. Markup is profit as % of cost. If you buy for $60 and sell for $100: margin = 40%, markup = 67%.
