Answer and Explanation:
a. To calculate the payback period, we need to determine the number of years it takes to recover the initial investment. We subtract the cash flows from the initial investment until the cumulative cash flows equal or exceed the initial investment.
For Project A:
Initial Investment = $44,000
Year 1 Cash Flow = $22,000
Year 2 Cash Flow = $17,600
Year 3 Cash Flow = $13,000
Cumulative Cash Flow:
Year 1: $22,000
Year 2: $22,000 + $17,600 = $39,600
Year 3: $39,600 + $13,000 = $52,600
The payback period for Project A is 2 years.
For Project B:
Initial Investment = $44,000
Year 1 Cash Flow = $21,000
Year 2 Cash Flow = $17,000
Year 3 Cash Flow = $15,000
Cumulative Cash Flow:
Year 1: $21,000
Year 2: $21,000 + $17,000 = $38,000
Year 3: $38,000 + $15,000 = $53,000
The payback period for Project B is 3 years.
b-1. To calculate the NPV, we need to discount the future cash flows to their present value and then subtract the initial investment.
PV Factor at 8%:
Year 1: 1 / (1 + 8%)^1 = 0.926
Year 2: 1 / (1 + 8%)^2 = 0.857
Year 3: 1 / (1 + 8%)^3 = 0.794
For Project A:
Year 1 PV = $22,000 * 0.926 = $20,372
Year 2 PV = $17,600 * 0.857 = $15,083
Year 3 PV = $13,000 * 0.794 = $10,322
NPV of Project A = ($20,372 + $15,083 + $10,322) - $44,000 = -$42,223
For Project B:
Year 1 PV = $21,000 * 0.926 = $19,446
Year 2 PV = $17,000 * 0.857 = $14,569
Year 3 PV = $15,000 * 0.794 = $11,910
NPV of Project B = ($19,446 + $14,569 + $11,910) - $44,000 = -$44,075
b-2. Based on the NPV method, we should choose Project A because it has a higher NPV (-$42,223) compared to Project B (-$44,075).
c. A firm should normally have more confidence in the answer derived based on the NPV method rather than the payback method. The NPV method considers the time value of money and provides a more comprehensive measure of profitability. It takes into account the discount rate and calculates the present value of all cash flows, giving a more accurate representation of the investment's value. On the other hand, the payback method only focuses on the time required to recover the initial investment without considering the profitability beyond that point.
