About the Return on Assets Calculator
This return on assets (ROA) calculator shows how much profit a business earns for every dollar of assets it controls. Enter net income for the year and total assets at the start and end of the year; add revenue to split ROA into profit margin and asset turnover.
Investors use ROA to compare how efficiently companies in the same industry use their resources, and owners use it to track whether new equipment, inventory or acquisitions are paying their way. Because it uses total assets, ROA reflects performance regardless of how the assets were financed — unlike return on equity, which leverage can inflate.
ROA varies widely by industry: banks and utilities hold huge asset bases and typically earn low single-digit ROA, while software and service firms can earn far more. Compare against peers and the company’s own history rather than a universal target.
With the default inputs, the return on assets (roa) is 10%. Change any value above to recalculate instantly.
How to use the return on assets calculator
- 1Enter net income from the income statement.
- 2Enter total assets from the opening and closing balance sheets.
- 3Optionally add revenue to see margin and asset turnover.
- 4Compare ROA with industry peers and prior years.
Formula and method
Average total assets is (opening assets + closing assets) ÷ 2, which matches the balance sheet to the income earned over the year. If only one balance is entered, that figure is used. ROA is net income divided by that average, expressed as a percentage.
The DuPont identity splits ROA into net profit margin (net income ÷ revenue) and asset turnover (revenue ÷ average assets). A low ROA can come from thin margins, from too many assets for the sales they generate, or both — the breakdown shows which lever to work on.
- Net income
- Profit after all expenses, interest and taxes
- Average total assets
- (Beginning + ending total assets) ÷ 2
- Asset turnover
- Revenue ÷ average total assets
Worked examples
Small manufacturer
Average assets are ($1.4M + $1.6M) ÷ 2 = $1.5M. Net income of $150,000 gives an ROA of 10%. That comes from a 7.5% profit margin multiplied by asset turnover of 1.33.
Bank with a large balance sheet
Earning $1.2M on $100M of assets is an ROA of 1.2% — typical for a bank. Its 20% margin is healthy, but revenue is only 6% of assets, so returns on assets stay low.
Loss-making year
A $40,000 loss on $400,000 of average assets is an ROA of −10%. Assets turn over a strong 2.25 times, so the problem is the −4.44% margin rather than asset efficiency.
Frequently asked questions
What is a good return on assets?+
Above 5% is often considered solid and above 10% strong, but it depends heavily on industry. Banks commonly earn about 1%, while asset-light software companies can exceed 15%. Compare with direct competitors.
What is the difference between ROA and ROE?+
ROA divides net income by total assets; ROE divides it by shareholders’ equity. Debt increases assets but not equity, so heavily leveraged companies can have a high ROE with a modest ROA.
Should I use average or ending total assets?+
Average assets are preferred because net income is earned over the whole year while the balance sheet is a snapshot. Using the ending balance can distort ROA if the company grew or shrank a lot.
How can a company improve ROA?+
Raise profit margins through pricing or cost control, or increase asset turnover by selling idle equipment, reducing excess inventory and collecting receivables faster.
