Quick Answer
Return on Assets (ROA) is a metric that shows how profitable a company is relative to the total money tied up in its assets. To calculate it, divide your annual Net Income by your Average Total Assets (the average of your assets at the start and end of the year).
Key Takeaways
- ✓ Efficiency Metric: ROA tells you how effectively the management team is using the company's equipment, cash, and inventory to generate a return.
- ✓ Higher is better: A higher ROA indicates that the company earns more money on less investment. Generally, an ROA of 5% is considered good, and 20% is considered excellent.
- ✓ Compare apples to apples: Never compare the ROA of a software company to the ROA of an airline. Capital requirements are totally different.
ROA versus ROE (Return on Equity)
Both ROA and ROE are measures of profitability, but they answer different questions.
ROA measures efficiency across all assets, regardless of who paid for them. It doesn't matter if the assets were bought with investor cash (equity) or bank loans (debt).
ROE measures return against the owner's equity. If a company takes on a massive amount of debt to buy new factories, those new factories are assets. Total assets increase, which drives ROA down. But because that money was borrowed, the owner's equity doesn't change. If those factories generate even a slight profit, ROE will skyrocket. Looking at both metrics together tells you if management is relying on high-risk debt to juice their returns.
Frequently Asked Questions
What is Return on Assets (ROA)?
Return on Assets (ROA) is a financial ratio that shows how profitable a company is relative to its total assets. It gives investors an idea of how effective the company is at converting the money it invests in assets into net income.
What is a good ROA?
A "good" ROA varies heavily by industry. Capital-intensive industries (like manufacturing or airlines) require massive expensive equipment, so their ROA is naturally lower (often 2-5%). Software or service businesses require very few assets to generate revenue, so their ROA can easily exceed 15-20%.
What is the difference between ROA and ROE?
ROA measures efficiency against all assets, regardless of how they were financed (debt vs. equity). Return on Equity (ROE) only measures profitability against the shareholders' equity. A company that takes on massive debt to buy assets might have a low ROA but a high ROE.
How do you calculate ROA?
The formula for ROA is Net Income divided by Average Total Assets, expressed as a percentage. Average Total Assets is typically calculated by adding the beginning and ending assets for the year and dividing by two.
