What term is used for a calculation that determines a product's ability to generate profits?

• A. Return on investment (ROI)
• B. Revenue per available room (RevPAR)
• C. Sample
• D. Public relations

Answer: (A)

Evaluating profitability through the lens of investment efficiency. This calculation shows how much profit an investment or project generates relative to its cost, expressed as a return on investment. By comparing net profit (revenue minus costs) to the amount invested, ROI reveals how effectively resources are turned into profit. It’s a direct measure of the product’s ability to generate profits because it links earnings to what was spent. For example, if you invest money and end up with a certain net profit, ROI tells you what percentage of that investment came back as profit.

Other terms here describe different ideas: RevPAR measures revenue per available room and is a performance metric for pricing and occupancy, not a profitability ratio. A sample is a subset used for analysis, not a profitability calculation. Public relations focuses on managing an organization’s image and communications, not on measuring profit relative to investment.
