Question

Gallatin Carpet Cleaning is a small, family-owned business operating out of Bozeman, Montana. For its services, the company has always charged a flat fee per hundred square feet of carpet cleaned. The current fee is $22.90 per hundred square feet. However, there is some question about whether the company is actually making any money on jobs for some customers—particularly those located on remote ranches that require considerable travel time. The owner’s daughter, home for the summer from college, has suggested investigating this question using activity-based costing. After some discussion, she designed a simple system consisting of four activity cost pools. The activity cost pools and their activity measures appear below:

Activity Cost Pool	Activity Measure	Activity for the Year
Cleaning carpets	Square feet cleaned (00s)	10,000	hundred square feet
Travel to jobs	Miles driven	144,500	miles
Job support	Number of jobs	1,700	jobs
Other (organization-sustaining costs and idle capacity costs)	None	Not applicable

The total cost of operating the company for the year is $372,000 which includes the following costs:

Wages	$	139,000
Cleaning supplies		34,000
Cleaning equipment depreciation		14,000
Vehicle expenses		32,000
Office expenses		68,000
President’s compensation		85,000
Total cost	$	372,000

Resource consumption is distributed across the activities as follows:

Distribution of Resource Consumption Across Activities
	Cleaning Carpets		Travel to Jobs		Job Support		Other		Total
Wages	77	%	14	%	0	%	9	%	100	%
Cleaning supplies	100	%	0	%	0	%	0	%	100	%
Cleaning equipment depreciation	69	%	0	%	0	%	31	%	100	%
Vehicle expenses	0	%	75	%	0	%	25	%	100	%
Office expenses	0	%	0	%	62	%	38	%	100	%
President’s compensation	0	%	0	%	33	%	67	%	100	%

Job support consists of receiving calls from potential customers at the home office, scheduling jobs, billing, resolving issues, and so on.

Required:

1. Prepare the first-stage allocation of costs to the activity cost pools.

2. Compute the activity rates for the activity cost pools.

3. The company recently completed a 600 square foot carpet-cleaning job at the Flying N Ranch—a 57-mile round-trip journey from the company’s offices in Bozeman. Compute the cost of this job using the activity-based costing system.

4. The revenue from the Flying N Ranch was $137.40 (600 square feet @ $22.90 per hundred square feet). Calculate the customer margin earned on this job.

Answer 1

1)

Vehicle expenses

	Cleaning Carpets	Travel to Jobs	Job Support	other
Wages	107030    [139000*.77]	19460   [139000*.14]	0	12510   [139000*.09]
Cleaning supplies	34000	0	0	0
Cleaning equipment depreciation	9660   [14000*.69]	0	0	4340   [14000*.31]
Vehicle expenses	0	24000     [32000*.75]	0	8000    [32000*.25]
Office expenses	0	0	42160   [68000*.62]	25840   [68000*.38]
President’s compensation	0	0	28050	56950
Total	150690	43460	70210	107640

2)

Activity cost pool		Overhead rate
Cleaning carpets	150690/10000	$ 15.069 per 100sq ft
Travel to jobs	43460/144500	$ .30076
Job support	70210/1700	$ 41.3
Other (organization-sustaining costs and idle capacity costs)	107640	0

3)cost of this job : [600*15.069/100]+[57*.30076]+[1*41.3].

         = 90.414+ 17.14332+ 41.3

         =$ 148.8573 [rounded to 148.86]

4)customer margin :137.4 -148.86 = (11.46)
