Return on sales calculator is a tool which makes it easier for you to calculate return on sales (ROS in short). If you wonder what it is, you're at a right place  in this short article, we will explain how to calculate the return on sales and how to evaluate the result. Additionally, we will provide you with a simpletouse return on sales formula and illustrate its usefulness with a stepbystep example.
What is the return on sales?
Return on sales is an indicator which measures both the profitability and efficiency of a company. It tells us how much net profit a company produces from its sales revenue after deducting all of the costs and taxes. In simple words, it shows what percentage of each dollar of sales is converted into profit. For example, if a company keeps $0.17 out of each dollar of sales, it means that its ROS is at a level of 17%.
Return on sales is especially useful when comparing the profitability of a company between different periods. When the value of ROS increases, it is a sign that a company is growing efficiently and its financial condition is improving; when it decreases over time, it may mean that a company has some troubles converting revenue into profit.
Return on sales formula
The return on sales is calculated by dividing the operating profit of a company by its net sales. As this indicator is always expressed by a percentage, the last step of calculations is multiplying the obtained fraction by 100%.
ROS = operating profit / net sales * 100%
The return on sales formula uses the following variables:

Operating profit  the profit from a company's business operations, so the gross profit decreased by operating expenses, depreciation and amortization. If a company doesn't have any nonoperating revenue (e.g., from interests or sales of assets), its operating profit is equal to EBIT.

Net sales  gross sales of a company adjusted by discounts, allowances, or returns.
How to calculate the return on sales?
Imagine a company "Sports Extreme" that sells sports equipment. It generates $200k net sales each month but requires $170k of costs in order to generate this revenue. Its competitor, "Star Active," has sales at the level of $50k, but their costs are much lower  only $35k. Which of the two companies has a higher return on sales?
 Calculate the operating profit of "Sports Extreme" by deducting their costs from the net sales:
operating profit = $200k  $170k = $30k
 Divide this result by the net sales to obtain ROS:
ROS = $30k / $200k = 15%
 Repeat the steps above for "Star Active":
operating profit = $50k  $35k = $15k
ROS = $15k / $50k = 30%
 Return on sales for "Sports Extreme" is at a reasonably high level of 15%. The second company, though, managed to achieve an astonishingly high ROS of 30%! Most enterprises out there are usually satisfied with a return on sales at the level of 510%; it means that both companies we just analyzed are indeed profitable. Naturally, to have a full picture, it would be highly advisable to take a look at the changes in ROS over the period of 23 years.
