Return on Sales (ROS) is a vital financial ratio. It measures operational efficiency by comparing net profit to total revenue. Learn how to calculate ROS, focusing on its role in evaluating profit from sales.
Return on sales ratio – definition
Return on sales is a financial ratio that measures a company's operational efficiency. It calculates how much profit a company makes from its sales by comparing net profit to total revenue.
To determine ROS, you divide operating income (earnings before interest and taxes, or EBIT) by net sales.
This metric is essential for evaluating a company's profitability, specifically how effectively it converts sales into profit. Operating expenses, operating costs, and cost of goods sold (COGS) all affect the ROS ratio.
Businesses use ROS to analyze cash flow efficiency, improve return on sales, and enhance operational efficiency and financial health.
What is return on sales (ROS)?
Return on Sales (ROS) measures a company's operational efficiency. It reveals the profit the company makes from every dollar of sales. High ROS shows increased efficiency, while low ROS may indicate financial problems. ROS is closely related to operating profit margin.
Formula and calculation of return on sales
First, find the company's net sales and operating profits on its income statement. Use this formula:
ROS = Operating Income / Net Sales
Operating profit equals earnings before interest or EBIT.
What return on sales reveals
When calculating return on sales, investors should note whether companies report net sales or revenue. Net sales equal gross revenues minus refunds and return credits. Retail companies usually report net sales, while others report their turnover. Here's how to calculate ROS:
Determine net sales or revenues on the income statement.
Find operating profit, excluding non-operating activities and expenses such as taxes and interest.
Divide operating profit by net sales.
Understand sales profitability
ROS calculates how efficiently a company generates profits from revenues. Shows the percentage of revenues that are converted into operating profits. Investors, creditors, and others depend on this ratio.
It indicates a company's ability to generate operating cash flow from revenues, indicating potential profits and the ability to repay debt.
ROS compares current and past periods to analyze trend and internal efficiency. It also compares ROS ratios across companies, but only within the same industry due to different sector margins.
Example of using ROS
Consider a company with sales of $100,000 and costs of $90,000 versus another company with sales of $50,000 and costs of $30,000. The latter is more efficient. A company can become more efficient by selling more and spending less. Alternatively, they can spend less and still get the same or more money.
ROS vs Operating Margin
Although similar, ROS and operating margin differ in the derivation of the formula. Operating margin is operating income divided by net sales, while ROS typically uses EBIT as the numerator.
Limits of ROS
ROS only compare companies in a similar industry that have similar business models and sales volume.
Different industries have different operating margins, which makes comparisons using EBIT confusing. To make broader comparisons, analysts often use EBITDA to neutralize the effects of financing, accounting, and tax policy.

Special considerations
You should only compare sales profitability between companies that operate in the same industry and have similar business models and sales volume. Comparing companies across different industries using earnings before interest, tax, and depreciation (EBIT) can be misleading due to varying operating margins.
Analysts often use EBITDA, which includes factors such as depreciation and amortization, to make more accurate comparisons across different industries and companies. This approach adjusts for the effects of finance, accounting and tax policies.
Instructions
What is a good ROS ratio?
A good ROS ratio varies by industry, but in general, a higher ROS ratio indicates better efficiency and profitability.
Is EBIT the same as ROS?
Return on sales (ROS) and operating margin are very similar profitability ratios, and are often used interchangeably. EBIT (earnings before interest and taxes) is not the same as ROS.
EBIT shows how profitable a company is, while ROS shows the profit a company makes from sales. ROS measures the efficiency of a company's profits from sales. ROI measures the return on investment in a company.
What is the difference between ROS and ROI?
ROS (return on sales) measures operational efficiency by comparing profit to sales, while return on investment (ROI) measures the return on total investment in the company.
What is the difference between ros and rock?
ROS (Return on Sales) compares profit with sales to evaluate operational efficiency, while ROC (Return on Capital) measures the return on invested capital of a company.
