1. What is the optimal service life for Laroche Livery’s fleet of vans?
选项:
A.Two years.
B.Three years.
C.Four years.
解释:
B is correct.
The way to solve the problem is to calculate the equivalent annual annuity and choose the service life with the lowest annual cost. For a two-year service life, the NPV is
The EAA (PV = –46,776.86, N = 2, and i = 10%) is –26,952.38.
For a three-year service life, the NPV is
=-65559.73
The EAA (PV = –65,559.73, N = 3, and i = 10%) is –26,362.54.
For a four-year service life, the NPV is
=-87211.26
The EAA (PV = –87,211.26, N = 4, and i = 10%) is –27,512.61.
The three-year service life has the lowest annual cost. Laroche should replace the vans every three years.
老师计算这题每个项目最后一期给的残值为什么不计入?我理解的是最后一期可以按照残值将货车vans出售,然后计算NPV
