Variable Costs<br />
Fixed Costs<br />
Direct Costs<br />
• Cost object: BMW X5s<br />
produced<br />
Example: Tires used in<br />
assembly of<br />
au<strong>to</strong>mobile<br />
• Cost object: BMW X5s<br />
produced<br />
Example: Salary of<br />
supervisor on<br />
BMW X5<br />
assembly line<br />
Indirect Costs<br />
• Cost object: BMW X5s<br />
produced<br />
Example: Power <strong>cost</strong>s at<br />
Spart<strong>an</strong>burg pl<strong>an</strong>t.<br />
Power usage is<br />
metered only <strong>to</strong> the<br />
pl<strong>an</strong>t, where<br />
multiple products<br />
are assembled.<br />
• Cost object: BMW X5s<br />
produced<br />
Example: Annual lease <strong>cost</strong>s<br />
at Spart<strong>an</strong>burg<br />
pl<strong>an</strong>t. Lease is for<br />
whole pl<strong>an</strong>t, where<br />
multiple products<br />
are produced.<br />

Before a decision c<strong>an</strong> be reached, the chairm<strong>an</strong> must also predict the number of<br />
people who will attend. Without knowledge of both <strong>to</strong>tal <strong>cost</strong> <strong>an</strong>d number of attendees,<br />
he c<strong>an</strong>not make <strong>an</strong> informed decision on a possible admission price <strong>to</strong> recover<br />
the <strong>cost</strong> of the party or even on whether <strong>to</strong> have a party at all. So he computes the unit<br />
<strong>cost</strong> by dividing the <strong>to</strong>tal <strong>cost</strong> ($1,000) by the expected number of people who will<br />
attend. If 1,000 people attend, the unit <strong>cost</strong> is $1 per person; if 100 attend, the unit <strong>cost</strong><br />
soars <strong>to</strong> $10.<br />
Unless the <strong>to</strong>tal <strong>cost</strong> is “unitized” (that is, averaged with respect <strong>to</strong> the level of activity<br />
or volume), the $1,000 <strong>cost</strong> is difficult <strong>to</strong> interpret. The unit <strong>cost</strong> combines the <strong>to</strong>tal<br />
<strong>cost</strong> <strong>an</strong>d the number of people in a h<strong>an</strong>dy, communicative way.<br />
Accounting systems typically report both <strong>to</strong>tal-<strong>cost</strong> amounts <strong>an</strong>d average-<strong>cost</strong>-perunit<br />
amounts. A unit <strong>cost</strong>, also called <strong>an</strong> average <strong>cost</strong>, is computed by dividing <strong>to</strong>tal<br />
<strong>cost</strong> by the number of units. The units might be expressed in various ways. Examples are<br />
au<strong>to</strong>mobiles assembled, packages delivered, or hours worked. Suppose that, in 2007, its<br />
first year of operations, $40,000,000 of m<strong>an</strong>ufacturing <strong>cost</strong>s are incurred <strong>to</strong> produce<br />
500,000 speaker systems at the Memphis pl<strong>an</strong>t of Tennessee Products. Then the unit<br />
<strong>cost</strong> is $80:<br />

If 480,000 units are sold <strong>an</strong>d 20,000 units remain in ending inven<strong>to</strong>ry, the unit-<strong>cost</strong> concept<br />
helps in the determination of <strong>to</strong>tal <strong>cost</strong>s in the income statement <strong>an</strong>d bal<strong>an</strong>ce sheet<br />
<strong>an</strong>d, hence, the fin<strong>an</strong>cial results reported by Tennessee Products <strong>to</strong> shareholders, b<strong>an</strong>ks,<br />
<strong>an</strong>d the government.<br />
Cost of goods sold in the income statement, 480,000 units × $80 per unit $38,400,000<br />
Ending inven<strong>to</strong>ry in the bal<strong>an</strong>ce sheet, 20,000 units × $80 per unit 1,600,000<br />
Total m<strong>an</strong>ufacturing <strong>cost</strong>s of 500,000 units $40,000,000<br />
Unit <strong>cost</strong>s are found in all areas of the value chain—for example, unit <strong>cost</strong> of product<br />
design, of sales visits, <strong>an</strong>d of cus<strong>to</strong>mer-service calls. By summing unit <strong>cost</strong>s throughout<br />
the value chain, m<strong>an</strong>agers calculate the unit <strong>cost</strong> of the different products or services they<br />
deliver <strong>an</strong>d determine the profitability of each product or service. M<strong>an</strong>agers use this information,<br />
for example, <strong>to</strong> decide which products they should emphasize <strong>an</strong>d the prices they<br />
should charge.<br />
