Question

Five years ago, Thomas Martin installed production machinery that had a first cost of $25,000. At that time initial yearly costs were estimated at $1,250, increasing by $500 each year. The market value of this machinery each year would be 90% of the previous year's value. There is a new machine available now that has a first cost of $27,900 and no yearly costs over its five-year minimum cost life. If Thomas Martin uses an 8% before-tax MARR, when, if at all, should he replace the existing machinery with the new unit?

Explanation / Answer

Answer:

First of all we need to find out the present value of old machinery and initial cash out flow

present value of old machinery

=25,000*(90%)* 5

=14762.25

Now we will find initial cash out flow

Cost of new machinery

27900

Less:

Resale value of existing machine

14762.25

Initial cash out flow

13137.75

It was given in the question that, at that time initial yearly costs were estimated at $1250, increasing by $500 each year. so current it passed 5 year of installing old machine and for the current year the exposes will be

Conclusion :

As NPV of the new machine is $5497.5 positive so company should replace the machinery now
