Which of the following financial metrics assesses a company's profitability relative to its total assets?

Return on Assets (ROA) is a financial metric that measures a company's ability to generate profit from its assets. It is calculated by taking net income and dividing it by total assets, which provides insight into how effectively the company is utilizing its assets to produce earnings.

ROA is particularly helpful for evaluating how well management is using its assets to create profit and is often used to compare the efficiency of different companies in the same industry. A higher ROA indicates that a company is more effective at converting its investment in assets into profits.

The other choices, while related to financial performance, do not specifically assess profitability relative to total assets. The Current Ratio measures liquidity, the Profit Margin assesses profitability relative to revenue, and Return on Investment evaluates the profitability of an investment relative to its cost, none of which directly focus on total assets in the manner that ROA does.
