Return on Assets (ROA)

Return on assets (ROA) is a profitability ratio that helps determine how efficiently a company uses its assets. It is the ratio of net income after tax to total assets. In other words, ROA is an efficiency metric explaining how efficiently and effectively a company is using its assets to generate profits.

Calculate Return On Assets (ROA) Using Formula

The formula for ROA is very simple which is expressed below:

Return on Assets = Profit after Taxes / Total Assets

The numerator is the profit considered after deducting the costs, depreciation, and tax, etc. One important thing to keep in mind while arriving at this figure is to consider the profits which are generated using such assets. Incomes generated from activities in which there is no contribution of these fixed assets should be excluded for this purpose. The denominator comprises fixed as well as current assets. A more accurate version of ROA is when average total assets are considered i.e., the average of the opening assets at the start of the accounting period and closing assets at the end of the accounting period.

A different expression of the ROA formula can be as follows and that gives a better and deeper insight into this ratio.

  Profit after Tax Total Revenue  
ROA=————–*————–=Profit Margin  *  Asset Turnover Ratio
  Total Revenue Total Assets  

From this expression, a company can make out what is driving its ROA. Is it because of higher profit margins or due to higher asset turnover? Say, a 20% ROA can be a result of 10% margin * 2 times asset turnover or 5% margin * 4 times asset turnover.

Return On Assets (ROA) Example

Below is a sample of financial figures for ABC Co.

All figures in USD. The accounting period under consideration is Financial Year 2011-12.

Net Profit after tax=20000
Non-current Assets  
Tangible Assets=50000
Intangible Assets=10000
Current Assets  
Accounts Receivables=5000
Total Assets=100000
Return on Assets=Profit after Tax / Total Assets

From the above illustration, ROA is 0.2 or 20%. From this, one can conclude that for every dollar invested in the assets of ABC Co, it results in a profit worth 20 cents. In other words, to create 1 unit of profit, 5 units need to be invested in the assets of the company.

Interpretation of Return on Assets (ROA)

Return on assets is a measure of how effectively a company uses its assets. Higher is this figure, better is the utilization of the company’s assets. For e.g., a company may earn profits worth 1 million with an investment of 10 million giving ROA of 10%. On the other hand, another company can give the same profit with an investment of just 5 million, giving a ROA of 20%. The second company certainly is utilizing its resources better because although both are generating the same profits, the second company is doing it with half the investment. It’s easier to generate profits if you pump in a huge amount of money. But one needs to consider the cost of capital and the opportunity cost as well with every investment being made.

Thus, investors can use the ROA figure to analyze which company has efficient utilization and thus make an informed choice before investing in a company. One can even compare ROA for a company over a period of 5-10 years. An increasing ROA suggests the profitability of the company is increasing. On the other hand, a decreasing ROA can be an indication that the company’s performance is deteriorating.

Reasons For Lower ROA

Lower Asset Productivity

Lower productivity of the assets is the key reason for lower ROAs. This can be cured by proper repair and maintenance or the replacement of old assets. The techniques of capital budgeting may help solve such dilemmas.


Too much wastages could also be inferred as a reason for lower ROA. Reducing wastages is a major challenge in most manufacturing companies. Wastages not only mean the product or raw material wastage, the wider meaning of wastage includes idle labor hours, etc. Proper production planning and the process of testing the products at every stage can significantly reduce wastages.

Other reasons could be the higher cost of machinery, higher interest rates, etc.

Caution While Using ROA Ratio

Return on assets of different companies can be compared only to companies within the same sector. Comparing ROAs of companies belonging to different sectors can be misleading. This is because some sectors require a huge initial investment and have long gestation periods. For such companies, ROA will be relatively low. E.g., companies belonging to the infra and airlines sector.
