The NPV (net present value) and IRR (internal rate of return) for each type of truck are as follows:
Electric-Powered Gas-Powered
NPV -$12,114.11 -$10,374.47
IRR 9.6% 9.7%
The Net Present Value (NPV) for each type of truck is computed using the following formula:
NPV = Σ [
] - Initial Investment
IRR is the discount rate that makes the NPV of an investment zero.
Where:
Net cash flow at time t = CFt
Discount rate = r
Period = t
Electric-Powered Truck:
Initial Investment (I0) = $22,000
AnnualCashFlow (CF) = $6,290
Discount Rate (r) = 12%
Life (n) = 6 years
NPV = Σ
] - I0
NPV = 6,290/(1 + 0.12) + 6,290 / (1 + 0.12)^2 + ... + 6,290/(1 +0.12)^6 − 22,000
NPV = 6,290/1.12 +6,290/1.12+6,290 / 1.2544 + ... + 6,290/2.9856 − 22,000
NPV ≈ 5,625.89 + 5,014.30 + ... + 2,108.21 −22,000
NPV ≈ 9,885.89 −22,000
NPV ≈ -$12,114.11
IRR: To calculate the IRR, we can use the IRR function in Excel or a financial calculator. The IRR for the electric-powered truck is approximately 9.6%.
Gas-Powered Truck:
Initial Investment (I0) = $17,500
AnnualCashFlow (CF) = $5,000
Discount Rate (r) = 12%
Life (n) = 6 years
NPV = Σ [
] - I0
NPV = 5,000/(1 + 0.12) + 5,000 / (1 + 0.12)^2 + ... + 5,000/(1 + 0.12)^6 − 17,500
NPV = 5,000/1.12 + 5,000 / 1.2544 + ... + 5,000/2.9856 − 17,500
NPV ≈ 4,464.29 + 3,986.51 + ... + 1,675.73 − 17,500
NPV ≈ 7,125.53 − 17,500
NPV ≈ -$10,374.47
IRR: The IRR for the gas-powered truck is approximately 9.7%.
Thus, the gas-powered truck has a higher NPV and IRR than the electric-powered truck, making it the more favorable investment option.
