Return on assets (ROA) is a company's net income divided by its total assets, shown as a percentage. It answers a simple question: for every dollar of assets the company owns (factories, inventory, cash, money owed by customers), how many cents of profit did it earn in the year? Because the assets are funded by both owners and lenders, ROA looks at the whole balance sheet, unlike return on equity, which looks only at the owners' share. Many analysts divide by the average of the opening and closing total assets instead of the year-end figure, because assets change during the year. Check the source's definition too: some textbooks (German and Chinese ones, for example) add the interest paid on loans back to the profit before dividing, because interest is the lenders' share of the result. This entry uses plain net income, the most common form.
Worked example
Company A earned a net income of $60,000 in the year and has total assets of $1,000,000. ROA = $60,000 ÷ $1,000,000 = 0.06, or 6%. Company B, in the same business, earned $40,000 on total assets of $500,000. ROA = $40,000 ÷ $500,000 = 0.08, or 8%. Company A made more profit in dollars, but Company B squeezed more profit out of each dollar of assets. Neither number says which company is better run on its own: it is a reason to ask why the gap exists.
Why it matters
ROA shows how productively a company uses everything it owns, which makes it a useful companion to the other profitability ratios. The figures come from the income statement (net income) and the balance sheet (total assets) in the annual report. The catch is comparability. Banks and insurers have huge balance sheets compared with their profit, so their ROA percentages look small next to a software company, which needs few assets. A shop or a factory sits in between. Compare ROA only with companies in the same industry and with the company's own earlier years. ROA also does not show how the assets were paid for, so two companies can post a similar ROA with very different levels of debt; read it next to return on equity and the debt-to-equity ratio. A low or high reading is a question to look into, not a verdict.

Frequently asked questions
ROA = net income ÷ total assets, multiplied by 100 to get a percentage. Net income comes from the income statement and total assets from the balance sheet. Some analysts use the average of the opening and closing total assets, which is fairer when the company grew or shrank during the year.
There is no single good level, because it depends on the industry. Banks and insurers usually show small percentages because their balance sheets are huge, while a business with few assets can show much higher ones. Compare a company with similar companies and with its own earlier years.
ROA divides profit by everything the company owns, whether it was paid for by owners or lenders. ROE divides profit by the owners' share only. A company that borrows heavily can show a modest ROA and a much higher ROE, so the two are best read together.
