The term gross profit margin refers to the ratio between revenue and gross profit. If the business is said to have a low margin, such as a grocery store, it means that the cost of sales is high in relationship to revenues. 100% markup becomes a 50% margin. With a cost of $1.00 and a 100% markup, the markup is $1.00 and gross revenue is $2.00. The markup is 100% of the cost (markup of $1.00/Cost of $1.00=100%). However, the margin is 50% â the markup divided by gross revenue (markup [or gross profit] of $1.00/Revenue of $2.00=50%).
