|
Single Plant Wide Rate. |
1 |
From a single aggregated cost pool, to products. |
A production volume related activity measure, e.g., direct labor hours, machine hours, etc. |
Plant produces only one, or a few similar products that consume all indirect resources in the same proportions, e.g., Product X consumes 10% of each indirect resource in the plant. |
|
Single Rate Per Department. |
2 |
From service departments, to producing departments' single cost pools (overhead accounts), to products. |
A production volume related activity measure. These may be different for each department. |
Each department produces only one, or a few similar products that consume all of a department's indirect resources in the same proportions, e.g., Product X consumes 20% of all indirect resources in Department A, 10% of all indirect resources in Department B, etc. |
|
Multiple Activity Based Rates Per Department. |
2 or more |
From service departments, to producing departments' activity cost pools, to products. |
Both production volume related and non-production volume related activity measures, e.g., number of purchase orders, number of setups, etc. |
Each department produces many products that consume resources within each department in different proportions, e.g., Product X consumes 30% of the power, 15% of the engineering work and 20% of the repair in Department A. Multiple rates are needed in Department A. |
