How is the Internal Rate of Return (IRR) calculated?

• A. NPV = CFs / (1 + IRR)^x
• B. 0 = CFs / (1 + IRR)^x
• C. IRR = CFs / Total Investment
• D. Cash flows = Debt/Equity ratio

Answer: (B)

The calculation of Internal Rate of Return (IRR) is fundamentally based on the principle of Net Present Value (NPV). IRR is the rate at which the NPV of an investment becomes zero, meaning that the present value of the expected cash inflows equals the present value of the expected cash outflows. In the context of the correct formulation, setting NPV to zero establishes the condition required to find the IRR. Thus, the equation indicates that when the cash flows (CFs) are discounted at the IRR, the sum of these discounted cash flows equates to the initial investment. This is critical for understanding how investments are assessed; IRR indicates the efficiency or profitability of different investment scenarios by considering the time value of money. The other options don't accurately represent how IRR is determined. For instance, calculating IRR through the division of cash flows by total investment doesn't capture the time-sensitive nature of cash flows, and the relationship of cash flows to the debt/equity ratio doesn't relate to the calculation of IRR. Hence, the approach of zeroing out NPV is the foundational concept for accurately calculating the IRR of an investment.
