Standard retail markup varies by product category but commonly falls between 50-100%, known as keystone pricing. Fashion and accessories often use 100%+ markup, while electronics may use 20-40%. The right markup depends on your market positioning and competitive landscape.

Markup is calculated as a percentage of cost, while margin is calculated as a percentage of the selling price. A 100% markup (doubling the cost) results in a 50% margin. Both measure profitability but from different reference points, so it is important not to confuse the two.

No. Different product categories have different competitive dynamics and customer price sensitivity. High-demand commodity products may need lower markups to stay competitive, while unique or exclusive products can support higher markups. Use a category-specific markup strategy for best results.
