Make vs Buy
Exercise #1
Western Company makes their own sub-product (handles) used in the manufacturing process (lawnmowers) the unit cost per handle is as follows:
DM $ 4
DL $ 5
Var. Ohd . $ 2
Fixed Ohd. $ 3*
$14
* Fixed manufacturing overhead related to the Handle Division is $150,000 spread over 50,000 handles.
Western Co. can buy 50,000 handles from an outside supplier for $12 per handle.
Reducing production of handles will reduce fixed costs by only $17,000 as many of the costs such as plant insurance, taxes, amortization will not change. The area used currently to make handles can be leased out to earn $14,000.
Should they MAKE or BUY?
Make vs. Buy
Exercise #2
Queen Company makes 20,000 units of Part R-3 each year. At this level of activity, the cost per unit for Part R-3 is:
Direct Materials $4.80
Direct Labour 7.00
Variable mfg overhead 3.20
Fixed mfg overhead 10.00
Total Cost per Part $25.00
An outside supplier has offered to sell 20,000 units of Part R-3 each year to Queen for $23.50 per part. If Queen accepts the offer, the facilities currently used to make R-3 can be rented out to another company for $150,000 per year.
Queen has calculated that $6 of the fixed manufacturing overhead being applied to R-3 would continue even if the part is purchased from the outside supplier.
REQUIRED: How much will profit change if the outside offer is accepted?
Make vs. Buy
Exercise #3
Mazak Corp. manufactures a component TXR for use in making a computerized lathe.
Normal unit production costs for TXR (based on production of 1,000 units) are:
Direct Materials $250
Direct Mfg. Labour $110
Mfg. Ohd.
Variable $120
Fixed $160
-------
Total Mfg. Cost per unit $640
-------
Mazak can purchase a TXR equivalent outside for $600 per unit.
They could then switch their current facilities to make QST. This QST would produce a net relevant amount of $80,000.
In addition, $100,000 of fixed costs related solely to TXR could be eliminated.
Should Mazak acquire TXR outside?
