Many small businesses confuse margin with markup โ and the mistake quietly costs them thousands. Here is the difference, the formulas, and why your margin is the number that actually matters.
Gross Margin vs Net Margin
- Gross margin = profit after only the cost of the product (revenue โ cost of goods)
- Net margin = profit after ALL expenses (rent, salaries, marketing, taxes)
The Margin Formula
Margin % = ((Revenue โ Cost) รท Revenue) ร 100
Example: You Sell an Item for $100 That Costs You $50
Margin = (($100 โ $50) รท $100) ร 100 = 50%
That means half of every sale dollar is gross profit.
Margin vs Markup: The Trap
Markup is the percentage added to your cost:
Markup % = ((Price โ Cost) รท Cost) ร 100
A 50% markup is NOT a 50% margin. Here is why:
| Cost | Markup | Selling Price | Actual Margin |
|---|---|---|---|
| $50 | 50% | $75 | 33% |
| $50 | 100% | $100 | 50% |
| $50 | 150% | $125 | 60% |
| $50 | 200% | $150 | 67% |
If you think a 50% markup gives you a 50% margin, you are underpricing by a third.
Converting Markup to Margin
Margin = Markup รท (1 + Markup)
Example: 100% markup โ 100 รท (1 + 1) = 50% margin.
