In a cost-benefit analysis for risk mitigation, which metric is commonly used to compare alternatives?

• A. Payback period
• B. Internal rate of return
• C. Net present value
• D. Break-even point

Answer: (C)

Net present value is used to compare risk mitigation alternatives because it accounts for the time value of money by discounting all expected cash inflows and outflows to their present value and then subtracting costs from benefits. This approach captures both how much money you expect to gain or lose and when those amounts occur, using a discount rate that reflects the organization’s cost of capital and the risk profile of the options. The option with the higher NPV represents greater value creation after considering timing and risk, making it a direct, comparable measure across different projects or strategies of varying sizes.

Other metrics miss important parts of the picture. Payback period focuses only on when the initial investment is recovered and ignores any value created after that point and the timing of later cash flows. Internal rate of return looks at the rate of return implied by the cash flows but can be misleading when comparing projects of different scales or with unconventional cash flows, and it doesn’t directly indicate how much value is created. Break-even point tells you when revenues cover costs but provides no information about overall profitability or risk-adjusted value.
