What is the primary use of the term 'Discount rate' in investment appraisal?

• A. The rate at which future cash flows are discounted to present value
• B. The rate of return required on equity only
• C. The tax rate applied to cash flows
• D. The rate of inflation

Answer: (A)

The discount rate is the rate used to translate future cash flows into their present value, capturing the time value of money and risk. In investment appraisal, you forecast all future cash inflows and outflows for a project and then discount them back to today using this rate. The sum of these present values tells you how valuable the project is in today’s terms and helps you decide whether to proceed. The discount rate essentially reflects the opportunity cost of capital—the return you could earn on an alternative investment with similar risk. For example, if you expect £100 in five years and use a discount rate of 8%, the present value is about £68. The higher the discount rate, the lower the present value of distant cash flows, which can change the investment decision. This concept is not limited to the rate of return on equity, nor is it simply a tax rate or a measure of inflation; inflation can influence the nominal discount rate, but the core idea is converting future amounts into today’s value based on risk and opportunity cost.
