functions of service departments.
Department that provides service
to other subunits in the
organization.
Cost center whose costs are
charged to other departments in
the organization.
Service Department User Department
Intermediate Cost Center
Cost center, such as a production
department, whose costs are not
allocated to another cost center.

Step Method
The step method allocates some service department
costs to other service departments.
Once an allocation is made from a service department no further
allocations are made back to that service department. Generally
allocate in order of proportion of services provided to other service
departments.

Reciprocal Method
Recognizes all services provided by any service department,
including services provided to other service departments
The reciprocal method accounts for cost
flows among service departments
providing services to each other.
It requires a
simultaneous equation
solution.

The Simultaneous Equation
1. Write the costs of each service
department in equation form.
Total Service
Department
Direct cost of the
service
department
Cost allocated from
other service
departments
2. Solve equations
simultaneously using
matrix algebra.

Net realizable value (NRV)
Sales value of each product at the split-off point.
Net realizable value method
Joint cost allocation based on the proportional values of
the products at the split-off point.
Estimated net realizable value
Sales price of a final product minus additional processing
costs necessary to prepare a product for sale.
