Quick Answer
Markup = profit as a % of cost. Margin = profit as a % of selling price. Same profit, different denominators. A 50% markup always equals a 33.3% margin — never 50%.
The Example That Makes It Click

You buy a product for $60. You sell it for $100. Your profit is $40.

Markup
66.7%
$40 / $60 (cost)
Margin
40.0%
$40 / $100 (price)
Profit
$40
Same either way

Both describe the same $40 profit. Markup divides by cost ($60). Margin divides by selling price ($100). That's the entire difference.

Why This Confusion Costs Money

Imagine your boss says "I want a 30% margin on everything." If you accidentally apply a 30% markup instead, you'd only get a 23% margin. On $1 million in revenue, that mistake costs you $70,000 in lost profit.

The #1 pricing mistake: Using markup when you mean margin. The #2 mistake: Using margin when you mean markup. Always clarify which one you're talking about.

When to use markup: When you know your cost and want to set a price. Common in retail and wholesale.

When to use margin: When you're analyzing financial performance. Used in financial statements, investor reports, and business planning.
