Cost $60, price $100 — the dual pair
- Input
- Cost = $60, Selling price = $100
- Working
- Profit = 100 − 60 = $40. Margin = 40 / 100 × 100 = 40%. Markup = 40 / 60 × 100 = 66.67%. Same $40 of profit, two percentages — because margin measures it against the $100 price and markup against the $60 cost.
- Result
- Profit = $40; margin = 40%; markup = 66.67%
