It's determined by dividing gross profit by net sales and is normally communicated as a rate. Net sales less cost of goods sold (COGS), which is the direct cost of producing the goods sold, is gross profit.

It is simpler to compare profitability with that of other businesses and to examine trends in profitability over time when profit is calculated as a percentage of revenue.

The rate at which a company converts revenue into profit is commonly measured using ROS.
