Return on investment (ROI) is a crucial metric that measures the expected benefit or the gain derived from an investment relative to its cost. It helps evaluate the efficiency and profitability of an investment by providing insights into how effectively capital is being utilized to generate returns. In essence, it can be expressed as a percentage, indicating how much profit or benefit is expected in relation to the investment made. This makes it an essential indicator for assessing the potential success of various investments, facilitating informed decision-making.

In comparison, the other options focus on different aspects of investments. While they provide valuable information, they do not capture the comprehensive measure of expected benefits that defines ROI. For instance, summarizing all expenses involved in an investment addresses the cost side but doesn't reflect the benefits expected. Similarly, detailing the total amount of assets acquired conveys the scale of the investment but not its efficiency or profit potential. Lastly, defining the time period required to recoup an investment relates more to payback period concepts, which is distinct from the overall returns expected from an investment. Thus, the definition encapsulated by the correct answer clearly aligns with the primary purpose of the ROI metric.
