Final answer:
The net present value (NPV) of the machine, when considering the after-tax net income for three years and the salvage value discounted at 12%, is -$1,298,266 after subtracting the initial investment of $1,800,000.
Step-by-step explanation:
To calculate the net present value (NPV) of the cash flows from the investment, you need to discount the expected net incomes and the salvage value to their present values using the provided discount factors for different years. You then subtract the initial cost of the machine from the sum of these present values to find the NPV.
Net income for each year is $200,000, and the discount factors for 12% are 0.8929 for year one, 0.7972 for year two, and 0.7118 for year three. The salvage value of $30,000 at the end of year three also needs to be discounted. Here are the calculations:
- Year 1 NPV: $200,000 × 0.8929 = $178,580
- Year 2 NPV: $200,000 × 0.7972 = $159,440
- Year 3 NPV (net income): $200,000 × 0.7118 = $142,360
- Year 3 NPV (salvage value): $30,000 × 0.7118 = $21,354
Add the NPVs for all three years plus the salvage value, and then subtract the initial investment to get the total NPV:
Total NPV = ($178,580 + $159,440 + $142,360 + $21,354) - $1,800,000 = $501,734 - $1,800,000 = -$1,298,266
