Question

Mountain Air Limited manufactures a line of room air purifiers. Management is currently evaluating the possible production of an air purifier for automobiles. Based on an annual volume of 10,000 units, the predicted cost per unit of an auto air purifier follows.

These cost predictions include $50,000 in facility-level fixed factory overhead averaged over 10,000 units.

The completed air purifier units include a battery-operated electric motor, which Mountain Air assembles with parts purchased from an outside vendor for $2.00 per motor. Mini Motor Company has offered to supply an assembled battery-operated motor at a cost of $5.00 per unit, with a minimum annual order of 5,000 units. If Mountain Air accepts this offer, it will be able to reduce the variable labor and variable overhead costs of the auto air purifier by 50 percent.


(a) Calculate the net benefit (cost) of outsourcing the electric motors from Mini Motor Company.
$Answer

(b) Calculate the net benefit (cost) of outsourcing the electric motors from Mini Motor Company, assuming the motor-assembly space could be rented to another company for $20,000 per year.
$Answer

(c) Management should consider which of the following nonquantitative factors in deciding whether to make or buy the motors.

The quality of their own and the supplier's motors.

The dependability of the supplier.

Whether Mini Motor has a track record of meeting its commitments.

Whether they can depend on Mini Motor to supply motors for a number of years or whether it is attempting to use some temporarily idle capacity.

All of these.

Direct materials $ 8.00 Direct labor 1.50 Factory overhead 7.00 Total $ 16.50

Explanation / Answer

Fixed overhead included in unit cost = 50000/ 10000 =$ 5 per unit

Variable factory overhead per unit = 7 -5 = $ 2 per unit

a) Additional cost per unit   = $5

Less:savings due to outsourcing

Variable labor (1.5*.50)         (.75)

Variable overhead(2*.50)     (1)

Total net additional cost per unit 3.25

Total additional cost = 3.25 *5000 = $ 16250

b)However if outsourcing would result in benefit of Rent =$ 20000

Net benefit = 20,000 - 16250 =$ 3750

c)All of these.

While deciding about offer,management should consider non quantitative factors ,ability to mee additional demand when needed, qualtiy ,other opprotunity benefit etc.
