Markup vs. Margin: They're Not the Same
People mix these up constantly. Markup is profit as a percentage of cost. Margin is profit as a percentage of selling price. Same dollar amount of profit, different denominators, completely different numbers.
Buy a shirt for $20, sell it for $30. Your profit is $10. Markup = $10 / $20 = 50%. Margin = $10 / $30 = 33.3%. Same shirt, same $10 profit.
The Formula
Profit = Selling Price − Cost
Margin% = Profit ÷ Selling Price × 100

Common Markup Rates by Industry
There's no universal "correct" markup. It depends entirely on your industry, competition, and overhead costs:
- Grocery stores: 25-50% markup on most items, lower on staples
- Clothing retail: 100-300% (the term "keystone" refers to exactly 100%)
- Electronics: 5-20%, razor-thin margins offset by volume
- Restaurants: 200-400% on food, 400-600% on drinks
- Jewelry: 100-400%, higher on fashion pieces
