What this calculator does
Return on assets (ROA) measures how efficiently a business turns everything it owns, cash, inventory, equipment, property, into profit. The return on asset formula divides net income by total assets and expresses the result as a percentage: a higher ROA means each dollar tied up in assets is producing more profit.
ROA is easy to confuse with return on equity (ROE). ROA looks at profit relative to everything the business owns, funded by debt or equity alike. ROE looks only at profit relative to the shareholders' own stake. A company can lift its ROE by borrowing more without becoming any more efficient at using its assets, which is exactly what ROA is designed not to be fooled by.
The formula
Divide net income by total assets, then multiply by 100 to express it as a percentage. Net income is profit after all expenses, interest and tax; total assets is everything the business owns, as shown on the balance sheet.
| Term | Meaning |
|---|---|
| ROA | Return on assets: (net income ÷ total assets) × 100. |
| Net income | Profit remaining after all operating costs, interest and tax have been deducted. |
| Total assets | Everything the business owns: cash, receivables, inventory, equipment, property and other holdings, as recorded on the balance sheet. |
The inputs explained
| Field | What to enter |
|---|---|
| Net income ($) | Net income for the period being measured, usually a full financial year. |
| Total assets ($) | Total assets from the balance sheet for the same period, typically the closing figure or an average of opening and closing. |
When to use it
Comparing two businesses in the same industry
ROA lets you compare how efficiently different companies use what they own, independent of how each one is financed. It is most meaningful when comparing businesses in the same industry, since asset intensity varies enormously between, say, a software company and a manufacturer.
Tracking a single business over time
A rising ROA over several years suggests a business is getting better at squeezing profit out of its asset base, whether through higher margins, faster turnover of inventory, or simply not carrying assets it does not need.
Separating operating efficiency from financing choices
Because ROA ignores how the assets were paid for, it isolates operating performance from the effect of leverage, which is the piece ROE adds back in.

Questions
What counts as a good ROA?
It depends heavily on the industry. Asset-light businesses such as software or services firms often post ROA well above 15%, while capital-intensive industries such as utilities or manufacturing commonly sit in the low single digits. Compare ROA within the same industry rather than against a universal benchmark.
What is the difference between ROA and ROE?
ROA divides net income by total assets, so it reflects operating efficiency regardless of financing. ROE divides net income by shareholders' equity only, so it also captures the effect of debt. A business can raise ROE by borrowing more without improving ROA at all.
Should I use average assets or closing assets?
Closing total assets is simpler and fine for a quick check. For a more precise year-on-year comparison, some analysts average the opening and closing total assets, which smooths out the effect of a large asset purchase or sale made partway through the period.
Can ROA be negative?
Yes, whenever net income is negative, meaning the business made a loss for the period. A negative ROA simply means the assets held during that period did not generate a profit, and the size of the negative figure shows how large that loss was relative to the asset base.
To see the same profit measured against shareholders' stake instead of total assets, use the return on equity calculator. For a full breakdown of what drives ROE into margin, turnover and leverage, see the DuPont analysis calculator.
