Profit Margin vs Markup: What's the Difference?
A 50% markup and a 50% margin sound like the same thing. They're not, and confusing them is one of the most expensive mistakes small businesses make. On a $12 product, 50% markup means you sell it for $18. A 50% margin means you sell it for $24. That's a $6 difference per unit. On a 500-unit wholesale order, that confusion costs $3,000 in revenue.
Here's exactly how each one works, a conversion table, and which one to use when.
The Definitions
Markup is how much you add to your cost to get your selling price. It's based on cost.
Margin is how much of the selling price is profit. It's based on revenue.
Same transaction, two different numbers. Always.
Chen's Candle Math
Each candle costs Chen $12 to make (wax, wick, jar, fragrance, label). He sells them for $24.
- Markup: ($24 – $12) ÷ $12 = 100%. He doubled his cost.
- Margin: ($24 – $12) ÷ $24 = 50%. Half the selling price is profit.
Same candle. 100% markup. 50% margin. These are not interchangeable.
Where Chen Went Wrong
The hotel asked for his markup. Chen said "50%." But he was thinking about margin. he wanted to keep 50% of revenue as profit. A 50% markup on a $12 candle means selling at $18 ($12 × 1.50). A 50% margin means selling at $24 ($12 ÷ 0.50).
By saying "50% markup" when he meant "50% margin," he sold 500 candles at $18 instead of $24. That's $3,000 in lost revenue and $1,200 in lost profit after costs.
The Quick Conversion
| Markup | Margin |
|---|---|
| 25% | 20% |
| 33% | 25% |
| 50% | 33% |
| 75% | 43% |
| 100% | 50% |
| 150% | 60% |
| 200% | 67% |
Notice: markup is always a bigger number than margin for the same transaction.
Which Should You Use?
Use markup when you're setting prices from cost. "My product costs $10, I want a 50% markup, so I'll charge $15."
Use margin when you're analyzing profitability. "Of every dollar in revenue, how many cents are profit?" Investors, lenders, and accountants all think in margin.
Most retail businesses price using markup but report results using margin. If you only learn one, learn margin. It's what shows up on your P&L and what anyone evaluating your business will ask about.
Frequently Asked Questions
Is a 50% margin the same as a 50% markup?
No. A 50% margin means you keep 50 cents of every dollar of revenue. A 50% markup means you add 50% to your cost. On a $10 item: 50% margin = $20 selling price. 50% markup = $15 selling price. Very different.
What is a good markup for retail?
Most retail businesses target 50–100% markup (equivalent to 33–50% margin). Luxury goods can go higher. Groceries are typically 25–50% markup.
How do I convert between markup and margin?
Margin = Markup ÷ (1 + Markup). Markup = Margin ÷ (1 – Margin). Or just use a calculator. It's faster.
