QUESTION 10
1 | 2 | 3 | 4 | 5 | |
Running Costs | -3000 | -3500 | -4000 | -4500 | -5000 |
Salvage Value | 25000 | 20000 | 15000 | 10000 | 5000 |
All financials below are in $.
As a first step we need to find the NPV of running the car for 5 years and then replacing it.
Let Ci be the running cost in year i. Let C0 be the initial investment and S be the salvage value at the end of year 5.
Cost of capital, R = 7%
N = Life = 5 years
= - 47,558.99
Let's assume the annual equivalent cost of replacing the vehicle every 5 years is EAC then
PV of annuity EAC = NPV
Or, EAC / R x [1 - (1 + R)-N] = NPV
Or, EAC / 7% x [1 - (1 + 7%)-5] = - 47,558.99
Hence, 4.1002 EAC = - 47,558.99
Hence, the annual equivalent cost of replacing the vehicle every 5 years = EAC = - $ 11,599.20
