Same profit, different denominator

If an item costs 75 and sells for 120, gross profit is 45. Margin divides 45 by the 120 selling price. Markup divides 45 by the 75 cost. Because the denominator differs, the percentages are not interchangeable.

Margin is useful for revenue planning

Gross margin shows how much of each sales currency unit remains after direct cost. It is commonly used when evaluating product economics and how much revenue is available to cover overhead.

Markup is useful for setting price from cost

If you start with known cost and apply a markup rule, markup can be intuitive. But a markup target must be translated correctly if management reports profitability as margin.

Use the right cost base

If “cost” excludes freight, packaging, wastage or direct labor that truly scales with the product, the reported gross margin can look healthier than the underlying economics.

Discounts reduce margin faster than many sellers expect

A 10% discount on selling price is not a 10% reduction in gross profit when margin is limited. Model the actual discounted selling price before approving promotions.
