Return On Sales, often abbreviated as ROS, is a fundamental financial metric that sheds light on a company's profitability. It’s important because it reflects a company’s efficiency in converting sales into profits

How to Calculate Return on Sales

ROS is calculated by dividing the company's Profit (Net Income) by its total Sales and then multiplying the result by 100 to get a percentage.  In simpler terms, ROS represents profit as a  percentage of sales revenue. 

Return on Sales (ROS)

ROS =
Net Income
Sales
× 100 %

Look at the 2023 results for Apple Inc.

Apple has great Return on Sales.
Visual Finance for Apple Inc. 2023

Divide the Net Income(96,995) by Sales (383,285) and multiply by 100 (to express it as a %). For Apple’s 2023 Results, Return On Sales is 25%.

Return on Sales (ROS) Calculation

ROS =
Net Income (96,995)
Sales (383,285)
× 100%

ROS = 25%

This means for every dollar Apple made in sales revenue, they kept $0.25 as profit.

What Is a Good Return on Sales?

A high Return On Sales percentage, like the 25% achieved by Apple in September 2023, indicates strong profitability. Most companies typically aim for a Return On Sales of 5-10%, making Apple's 2023 performance particularly noteworthy.

Other companies with noteworthy ROS:  In 2023 Google had ROS of 24%, Facebook was 29%, and Microsoft 2023 was a whopping 36%!

What Is a Negative Return on Sales?

In the other direction: 2021 is the last year for Twitter being publicly traded, and they had a negative Return On Sales (-4%).

Twitter had a loss in 2021 so the Return on Sales was also negative.

If you’re unprofitable and losing money, your bottom line will be a negative number and you will have a negative Return On Sales.

Negative Net Income and ROS signifies that a company is operating at a loss (expenses exceed sales revenue); but it does not tell the whole story. If your Gross Margin is positive, increasing sales volume could potentially turn the situation around by covering fixed costs and leading to profitability.

Twitter had a positive Gross Profit (or Gross Margin) in 2021.

Twitter had a positive Gross Profit (or Gross Margin) in 2021.

However, the Operating Expenses were significant, and the Operating Income was negative.  (So was the Net Income at the bottom of the Income Statement!). 

In general, businesses need to carefully manage expenses and revenue streams to achieve sustainable profitability.

THE TRIANGLE OF RATIOS

It's important to note that Return On Sales is a single metric. It doesn't provide a complete picture but it does serve as a key component in evaluating overall financial health, especially when considered alongside other metrics such as Asset Turnover and Return On Assets.

Key Financial Metrics

Return on Sales: = Profit Sales (as %)

Asset Turnover: = Sales Assets

Return on Assets: = ROS × ATO = Profit Assets (as %)

These three ratios work together as a triangle,  but you must understand each individual term to make sense of the relationship.

Looking at the Income|Outcome business simulation game board, you can see that the Triangle of Ratios actually connects the Income Statement and the Balance Sheet – you need both financial statements for the ‘big picture’.

Using Return on Sales

Objective: To enhance your understanding of a company's operational efficiency and profitability by analyzing changes in its Return on Sales over two years.

Instructions

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

2. Use the Visual Finance App OR locate an annual report for the company and open the Income Statement (and get out a calculator)

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.

ROS =
Net Income
Sales
× 100 %

You can 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 (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. 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!
