Today's goals
By the end of class, you'll be able to…
- Distinguish gross, operating, and net profit
- Calculate a profit margin
- Explain what margins reveal about a business
Warm-up
Business A made $1 million in profit on $50 million of sales. Business B made $1 million on $2 million of sales. Which is more impressive? Why?
Think, then write your answer.
The big idea
Profit and Margins
Gross profit, net profit, and why margins tell you more than totals.
Understanding Businesses · Lesson 2
"Profit" means different things at different stages. Analysts look at three:
- Gross profit = revenue − cost of goods sold (COGS). How much is left after paying for what was sold.
- Operating income = gross profit − operating expenses. What the core business earns.
- Net profit (net income) = operating income − interest and taxes. The bottom line.
Vocabulary
Margin
A profit number divided by revenue, shown as a percentage. A 10% net margin means the company keeps 10 cents of every dollar of sales.
Understanding Businesses · Lesson 2
Margins let you compare businesses of different sizes. They also reveal the type of business: software companies often have very high gross margins because an extra copy costs almost nothing to make, while grocery stores famously run on thin net margins — often just a few percent.
Understanding Businesses · Lesson 2
Thin margins aren't bad by themselves, but they leave little room for error. A small rise in costs can erase all the profit.
See it
Revenue of $120,000 becomes gross profit of $78,000 (65% margin), operating income of $18,000 (15%), and net profit of $14,000 (11.7%).

Real example
Same profit, very different businesses
Two hypothetical companies each earn $1 million in net profit.
- Company A has $2 million in revenue — a 50% net margin.
- Company B has $50 million in revenue — a 2% net margin.
Now suppose costs rise by 3% of revenue for both. Company A still earns a healthy profit. Company B's $1.5 million cost increase wipes out its entire profit — it now loses $500,000. Same profit on paper; very different fragility.
Try it together
Try it: margin calculator
This is Company B: $50 million in revenue and a 2% net margin. Raise operating expenses by $1,500,000 and watch the profit disappear.
Your numbers
Direct costs of what was sold: ingredients, inventory, materials.
Running the business: wages, rent, marketing, software.

Margin Match
- Give groups four made-up net margins — 2%, 6%, 15%, and 30% — and four business types: grocery store, restaurant, jewelry store, and software company.
- Groups match each margin to a business and explain their reasoning (how much does each sale cost to produce?).
- Reveal a sensible match and discuss: which business is most fragile if costs rise 5%?
Check for understanding · 1 of 3
A company has $500,000 in revenue and $300,000 in cost of goods sold.
What's its gross margin?
- A60%
- B$200,000
- C40%
- D30%
C. 40%
Gross profit = $500,000 − $300,000 = $200,000. $200,000 ÷ $500,000 = 40%. (The $200,000 is gross profit, not the margin.)

Why do software companies often have very high gross margins?
- AThey don't pay employees.
- BDelivering one more copy of software costs very little.
- CThey don't have customers.
- DTaxes don't apply to software.
B. Delivering one more copy of software costs very little.
Once software is built, each extra sale adds little cost of goods sold — though building it and running the company still cost a lot.
Check for understanding · 3 of 3
A business with a 2% net margin is more vulnerable to rising costs than one with a 30% net margin.
- True
- False
True
With thin margins, a small cost increase can erase all the profit.
Remember
Key takeaways
- Gross → operating → net: three levels of profit.
- Margin = profit ÷ revenue.
- Margins reveal the kind of business and its fragility.
- Thin margins leave little room for rising costs.
Discuss
Talk it over
- Would you rather run a high-margin business with few customers or a low-margin business with many? Why?
- What could a grocery store do to protect its thin margins?
