Question

JK Manufacturing would like to install a machine costing $37,500 with a life of 12 years to bring in benefits to the company of $5,100 per month. The monthly expenses for the machine are $4,650. If the MARR that the company uses is 12% per year, what should be the minimum salvage value as a percentage of the initial machine cost that the company should get at the end of the machine life to justify installing the machine?

Around 12%

Around 24%

Around 36%

Around 48%

Around 12%

Around 24%

Around 36%

Around 48%

Explanation / Answer

Ans: Around 36%

Explanation:

Here, Interest rate per month = 12% / 12 = 1%

     Number of interest period = 12 year * 12 = 144

     Net revenue per month = 5100 - 4650 = 450

To justify the installation of the machine, let us equate NPV = 0

NPV = -37,500 + 450(P/A, 1%, 144) + F(P/F, 1%, 144)

    0 = -37500 + 450(76.1372) + F(0.2386)

    0 = -37500 + 34261.74 + F(0.2386)

    0 = -3238.26 + F(0.2386)

F(0.2386) = 3238.26

F = 3238.26 / 0.2386

   = $13,572

Thus, minimum salvage value should be $13,572.

Thus, the minimum salvage value as a percentage of the initial machine cost = (13,572 / 37,500) * 100 = 36%
