Question

Futura Company purchases the 63,000 starters that it installs in its standard line of farm tractors from a supplier for the price of $11.00 per unit. Due to a reduction in output, the company now has idle capacity that could be used to produce the starters rather than buying them from an outside supplier. However, the company’s chief engineer is opposed to making the starters because the production cost per unit is $11.40 as shown below: Per Unit Total Direct materials $ 4.00 Direct labor 3.20 Supervision 1.50 $ 94,500 Depreciation 1.40 $ 88,200 Variable manufacturing overhead 0.80 Rent 0.50 $ 31,500 Total product cost $ 11.40 If Futura decides to make the starters, a supervisor would have to be hired (at a salary of $94,500) to oversee production. However, the company has sufficient idle tools and machinery such that no new equipment would have to be purchased. The rent charge above is based on space utilized in the plant. The total rent on the plant is $90,000 per period. Depreciation is due to obsolescence rather than wear and tear. Required: What is the financial advantage (disadvantage) of making the 63,000 starters instead of buying them from an outside supplier?

Answer 1

	Per unit		Total 63000 units
	Make	Buy	Make	Buy
Direct materials	4.00		252000
Direct labor	3.20		201600
Variable manufacturing overhead	0.80		50400
Supervision	1.50		94500
Purchase cost		11		693000
Total			598500	693000
Difference in favor of making	94500	=693000-598500
Financial advantage = 94500
