Question
X Company currently buys 7,500 units of a component part each year from a supplier for $8.00 each, but it is considering making the part instead. In order to make the part, X Company will have to buy equipment that will cost $150,000. The equipment will last for six years, at which time it will have zero disposal value. X Company estimates that it will cost $31,385 a year to make the 7,500 units. What is the approximate rate of return if X Company makes the part instead of buying it from the supplier?
Explanation / Answer
Let rate of return=6%
NPV=Prevsent Value Of Inflow-Present Value of Outflow
Present value of inflow=$31,385*4.9173
=$154329.46
NPV=$154329.46-$150000
=$4329.46
Let R=10%
Present Value of inflow=$31,385*4.355
=$136681.67
NPV=$136681.67-$150000
=(13318.32)
Rate of return=Lower rate+(lower rate NPV/Lower rateNPV-higer rateNPV)(Higher Rate-Lower Rate)
=6+(4329.46/4329.46+13318.32)(10-6)
=6.98130%
