What is a risk-adjusted discount rate and how is it used in project appraisal?

• A. It is a discount rate adjusted for project risk to reflect expected return; used to calculate risk-adjusted net present value
• B. It is a fixed rate for all projects
• C. It is the same as the cost of capital
• D. It is not used in NPV calculations

Answer: (A)

A risk-adjusted discount rate captures the extra return investors require for bearing a project’s risk, and you use it in project appraisal to discount expected cash flows to their present value. By applying a rate that reflects the specific risk of the project, the resulting value—risk-adjusted NPV—tells you whether the project adds value given its risk profile. If the project is riskier, the discount rate is higher, which lowers the present value of future cash flows and makes the NPV less favorable; if the project is less risky, the rate is lower, lifting the NPV. This rate is usually derived from the firm’s cost of capital with an added risk premium or via CAPM-based methods, aligning the hurdle rate with the required return for that risk. It is indeed used in NPV calculations to assess viability.
