Calculate Return on Sales

Objective: To increase your understanding of a company's operational efficiency and profitability by analyzing changes in its Return on Sales over a period of 2-3 years.

Return on Sales (ROS) is a financial metric that measures a company's operational efficiency by calculating the percentage of revenue that is converted into profit. It is calculated by dividing Profit (Net Income) by Net Sales.

Return On Sales is part of the Income|Outcome triangle of key ratios.
The Income|Outcome Triangle shows Return On Sales (i.e. the Profitability Ratio).

A higher ROS indicates that a company is more effective at converting sales into actual profit, reflecting strong operational performance. Conversely, a lower ROS may suggest inefficiencies in managing expenses relative to revenue.

However, in some contexts, Operating Profit (Operating Income or EBIT) is used in the calculation of ROS to assess a company's operational efficiency, excluding non-operating factors like taxes and interest. This version of ROS is often referred to as Operating Profit Margin.

Instructions

1. Select a Company for analysis (your company, a customer, a competitor, or a company you are considering investing in).

2. Gather the data for several years (or you can compare 2 or 3 companies).

Return on Sales (ROS)

ROS =
Net Income
Sales
× 100 %

Use the Visual Finance App OR locate an annual report for the company and open the Income Statement,

The annual report will show financial data for the reporting year and 1 or 2 years previous. Remember it may have a different name:

  • Statement of Earnings
  • Profit and Loss Statement (P&L)
  • Statement of Profit and Loss
  • Statement of Operations
  • Statement of Comprehensive Income


3. Look at the Return on Sales for each year.

Enter Revenue, Operating Profit, and Net Profit for three years (or three companies). You can edit the labels if needed.

Calculate ROS (Return on Sales) and Operating ROS. Operating ROS is used by companies that focus on core profitability before interest and taxes.

You can also find an ROS calculator at the Return On Sales entry in the Visual Finance Glossary.

4. Identify Key Factors:

Analyze the components that affect ROS, such as revenue growth, cost management, and expense control.  If there is a dramatic change in the ROS ratio, you will need to look more closely at the Income Statement to identify what is driving the change.  

  • Look for any one-time events or unusual items that impacted the ROS.
  • Events that are not part of regular operations will be detailed in Adjustments (line item(s) near the bottom of the Income Statement).
  • You may find additional information in the Notes to the Financial Statements.  


5. What is Your Analysis?

  • Did the ROS increase or decrease? By how much?
  • What might have contributed to this change (e.g., changes in revenue, cost of goods sold, operating expenses)?


6. Earn Bonus Points: Use the Visual Finance App to quickly bring up one or more competitors for your selected company.  Which company has the better ROS? Can you determine why?

This Return on Sales exercise drives deeper insights into a company's operational efficiency and profitability. Happy analyzing!
