Return on Assets (ROA) is a financial metric used to assess how efficiently a company utilizes its assets to generate profit. The correct formula for calculating ROA is net income divided by average total assets. This ratio gives insights into the company's ability to convert investment in assets into earnings.

Using average total assets rather than total assets at year-end provides a more accurate representation of the company's performance over a period, especially when there are significant fluctuations in asset levels during that time. This approach smooths out changes in asset values and provides a more reliable indicator of the firm's efficiency in using its assets.

Other formulas presented—like net income divided by total assets—would not account for fluctuations during the accounting period and can lead to misleading interpretations. Similarly, using total sales in the calculation emphasizes revenue generation rather than the effectiveness of asset management. Lastly, dividing net income by equity provides a measure of return on equity, but does not relate to asset efficiency in the same context as ROA. Therefore, concentrating on average total assets makes a significant difference in accurately reflecting a company's operational performance.
