Reciprocal method definition
/What is the Reciprocal Method?
The reciprocal method uses simultaneous equations to allocate the costs incurred by service departments to other departments; allocations are also made between the service departments. This method results in an accurate distribution of costs. The method is rarely used, since there are somewhat less accurate methods available that require fewer calculations.
How the Reciprocal Method Works
There are three steps involved in the calculation of the reciprocal method, which are as follows:
Set up a formula for each service department that describes its own direct costs, plus a fraction of the costs incurred by other service departments on its behalf.
Simultaneously solve the equations for the set of service departments. This results in a cost total for each of the service departments.
Allocate the reconfigured service department costs to the various production departments, using whichever allocation method appears to make the most sense. For example, costs may be allocated based on square footage used, machine hours used, or the number of production line hours used.

Advantages of the Reciprocal Method
The reciprocal method of cost allocation offers several advantages over other methods like the direct or step-down methods. Here are its key benefits:
Full recognition of interdepartmental relationships. The reciprocal method accounts for the mutual services provided between service departments. This leads to a more accurate representation of costs.
Greater accuracy in cost allocation. By considering all interdepartmental flows, the method ensures that costs are allocated based on actual resource usage. This is particularly valuable in organizations where service departments significantly rely on one another.
Equitable distribution of costs. Costs are allocated fairly and consistently, reflecting the true cost of services consumed by each department.
Better decision-making. The improved accuracy of cost allocation helps managers make better decisions regarding pricing, budgeting, and resource allocation.
Enhanced transparency. By explicitly modeling the interactions between service departments, the method provides greater insight into how costs are distributed. This can help identify inefficiencies or areas for cost-saving within service departments.
Comprehensive approach. Unlike simpler methods, the reciprocal method incorporates all cost interactions, ensuring no interdepartmental relationship is ignored.
Supports performance evaluation. Because it assigns costs more precisely, the reciprocal method provides better data for evaluating the performance of both service and operating departments.
By capturing the full complexity of cost flows, the reciprocal method provides a level of precision and fairness that other methods may lack, making it particularly suitable for organizations with substantial interdepartmental dependencies.
