Sell price from cost + markup %.
Selling price = cost × (1 + markup%). Markup is different from margin — 60% markup is not 60% margin.
60% markup on $40 = $64 sale price; margin on that sale = $24/$64 ≈ 37.5%.
This gap between markup and margin percentages widens as the markup gets larger, which is why relying on markup alone can make a pricing strategy look more profitable on paper than the actual margin delivers.
$40 cost × (1 + 60%) = $64.00 selling price.
Markup is profit as a % of cost; margin is profit as a % of selling price. Higher markups always give lower margins for the same profit.
Wildly variable: grocery 5–15%, clothing 100–300%, jewelry 200–500%. Depends on turnover and category norms.
100% markup — a common point of confusion, since it's tempting to assume a 50% markup gives a 50% margin, but the two only converge at zero.
