Support and Producing Departments
Support departments are units within an organization that provide essential support services for producing departments.
Examples: maintenance, grounds, engineering, housekeeping, personnel, and stores
Producing departments are units within an organization that are directly responsible for creating the products or services sold to customers.
Examples: Services: auditing, tax, management advisory Manufacturing: grinding and assembly

Definitions
Mutually beneficial costs, which occur when the same resource is used in the output of two or more services or products, are common costs.
Example: security guard wages at a factory
Causal factors are variables or activities within a producing department that provoke the incurrence of service costs.

Steps in Allocating Support Department Costs to Producing Departments
1. Departmentalize the firm.
2. Classify each department as a support or a producing department.
3. Trace all overhead costs in the firm to a support or producing department.

A Single Charging Rate Example A firm developed an in-house photocopying department to
serve its three producing departments (audit, tax, and management advisory systems or MAS).
The costs of the photocopying department include fixed costs of $26,190 per year and variable costs of $0.023 per page copied.
Estimated usage in pages by the three producing departments is as follows:
Audit department 94,500
Tax department 67,500
MAS department 108,000
Total 270,000

PPT 7 -12
A Single Charging Rate (continued)
Total costs = $26,190 + (270,000 x $0.023) = $32,400
Overhead rate = $32,400 270,000 = $0.12 per page
Suppose the actual usage per department is:
Audit department 92,000Tax department 65,000MAS 115,000

Budgeted Versus Actual Usage
When we allocate support-department costs to the producing departments, should we allocate actual or budgeted costs?
Budgeted costs

PPT 7 -15
Budgeted Versus Actual Usage (continued)
There are two basic reasons for allocating support-department costs.
1. To calculate unit costs
2. For performance evaluations

Choosing A Service Department Cost Allocation Method
The three methods for allocating service department costs to producing departments are:
The Direct Method
The Sequential Method
The Reciprocal Method
![Page 17: 07 Support Department Cost Allocation](https://reader033.fdocuments.net/reader033/viewer/2022061302/54e936694a795922038b4791/html5/thumbnails/17.jpg)

Reciprocal Method
The reciprocal method of allocation recognizes all interactions among support departments.

PPT 7 -22
Reciprocal Method (continued)
The cost equation for each support department can be expressed as follows:
P = Direct costs + Share of Maintenance’s cost
P = $250,000 + 0.1(M)
M = Direct costs + Share of Power’s costs
M = $160,000 + 0.2P
![Page 23: 07 Support Department Cost Allocation](https://reader033.fdocuments.net/reader033/viewer/2022061302/54e936694a795922038b4791/html5/thumbnails/23.jpg)
PPT 7 -23
Reciprocal Method (continued)
Substituting the Power equation into the Maintenance equation, we get:
M = $160,000 + 0.2 ($250,000 + 0.1M)
M = $160,000 + $50,000 + 0.02M
0.98M = $210,000
M = $214,286

PPT 7 -24
Reciprocal Method (continued)
Substituting the value for M into the Power equation we get:
P = $250,000 + 0.1 ($214,286)
P = $250,000 + $21,429
P = $271,429

Departmental Overhead Rates
The overhead rate for the grinding department is computed as follows (assuming the normal level of activity is 71,000 MH):
OH rate = $359,286 71,000 = $5.06 per MH
The overhead rate for the assembly department is computed as follows (assuming the normal level of activity is 107,500 DLH):
OH rate = $210,715 107,500 = $1.96 per DLH
