How is the rate of return expressed?

The rate of return is expressed as a percentage of the money saved or invested. This percentage indicates how much profit or loss has been made relative to the initial investment amount. By expressing the rate of return as a percentage, it provides a standard way to evaluate the effectiveness of different investments regardless of their absolute size. It allows for easy comparison between different investment opportunities; higher percentages indicate better returns relative to the amount invested.

Other choices, such as expressing the rate in dollar amounts or as a fraction, do not provide the same level of clarity or context needed to evaluate performance. Explaining it solely through a total investment amount is also not effective, as it fails to highlight the gain or loss as a proportion of what was initially put at risk. Representing the rate of return as a percentage effectively communicates profitability in a clear and comparable manner.
