Answer :
Let's solve this step-by-step using the information provided.
1. Identify the Cash Flows:
- Initial cost in Year 0: [tex]\(-\$150,000\)[/tex]
- Annual savings from Year 1 to Year 6: [tex]\(\$42,500\)[/tex] each year
- Overhaul cost at the end of Year 4: [tex]\(-\$25,000\)[/tex]
- Salvage value at the end of Year 6: [tex]\(\$7,500\)[/tex]
2. Construct the Cash Flow Timeline:
- Year 0: [tex]\(-\$150,000\)[/tex] (initial investment)
- Year 1: [tex]\(\$42,500\)[/tex]
- Year 2: [tex]\(\$42,500\)[/tex]
- Year 3: [tex]\(\$42,500\)[/tex]
- Year 4: [tex]\(\$42,500 - \$25,000 = \$17,500\)[/tex] (savings minus overhaul cost)
- Year 5: [tex]\(\$42,500\)[/tex]
- Year 6: [tex]\(\$42,500 + \$7,500 = \$50,000\)[/tex] (savings plus salvage value)
3. Net Present Value (NPV) Calculation:
The NPV formula is:
[tex]\[
NPV = \sum \left( \frac{\text{Cash Flow}_{t}}{(1+\text{rate})^t} \right)
\][/tex]
where [tex]\( \text{Cash Flow}_{t} \)[/tex] is the cash flow at time [tex]\( t \)[/tex] and [tex]\(\text{rate}\)[/tex] is the cost of capital (12% = 0.12).
- Calculate NPV:
[tex]\[
NPV = -150,000 + \frac{42,500}{1.12^1} + \frac{42,500}{1.12^2} + \frac{42,500}{1.12^3} + \frac{17,500}{1.12^4} + \frac{42,500}{1.12^5} + \frac{50,000}{1.12^6}
\][/tex]
4. Internal Rate of Return (IRR):
IRR is the discount rate that makes the NPV of all cash flows from the investment equal to zero—or the breakeven point for the investment. It's generally calculated using a financial calculator or software.
5. Present Value Index (Profitability Index):
The Present Value Index (PVI) or Profitability Index is calculated as:
[tex]\[
\text{PVI} = \frac{\text{NPV} + \text{Initial Investment}}{\text{Initial Investment}}
\][/tex]
Now, to compute the exact numbers, you could use a financial calculator or an Excel spreadsheet to plug in these values to compute the NPV, IRR, and PVI.
