The reciprocal services method, also known as the reciprocal allocation method or the simultaneous equation method, is an approach used to allocate support department costs to other departments in an organization. It considers the mutual services or interactions between support departments by solving a system of simultaneous equations to determine the cost allocations.
Here are some key points about the reciprocal services method for applying support department costs:
- Allocation Process: The reciprocal services method takes into account the reciprocal or mutual services provided by support departments to each other. It recognizes that support departments not only provide services to operating departments but also receive services from other support departments. It aims to allocate costs based on the actual usage or consumption of support services.
- Simultaneous Equations: The reciprocal services method involves setting up a system of simultaneous equations to determine the cost allocations. Each equation represents the relationship between the costs incurred by support departments and the services received and provided.
- Cost Allocation Example: Let’s consider an example with two support departments: Human Resources (HR) and Information Technology (IT), and two operating departments: Production and Sales. The reciprocal services method would involve setting up equations that express the costs of HR and IT in terms of the costs incurred by each department and the services received from the other department. These equations are solved simultaneously to determine the cost allocations.
- Interdepartmental Services: The reciprocal services method requires a detailed understanding of the services provided and received between support departments. It involves quantifying and evaluating the nature and extent of the reciprocal services. This information is used to construct the simultaneous equations and determine the cost allocations.
- Simultaneous Equation Solution: Once the system of simultaneous equations is set up, it is solved to find the values of the cost allocations for each department. Various methods can be used to solve the equations, such as matrix algebra or iterative calculation procedures.
- Accuracy and Complexity: The reciprocal services method provides a more accurate allocation of support department costs by considering the reciprocal nature of services. It reflects the actual usage of support services and leads to a fairer distribution of costs. However, it can be complex and time-consuming to implement, requiring detailed data on interdepartmental services and the ability to solve simultaneous equations.
The reciprocal services method is a more sophisticated approach for allocating support department costs that considers the reciprocal or mutual services provided by support departments. It aims to provide a more accurate reflection of the cost sharing and usage of support services within an organization. However, it requires careful analysis of interdepartmental relationships, data collection, and solving simultaneous equations, making it more complex than simpler allocation methods.
