To continue with the preceding example, Henderson Industrial decides to stop recording normal spoilage in its bills of material, and instead records the actual cost of spoilage in a manufacturing overhead cost pool. It calculates this cost by adding up the number of spoiled cartons and multiplying by the component cost of each one. In May, the calculation is:
1,500 spoiled cartons x $0.25/unit resin cost = $375
Henderson’s cost accountant includes this cost in the manufacturing overhead cost pool, which is comprised of the following costs in May:
|
Manufacturing Overhead Line Item |
Amount |
|
Manufacturing supervisor salaries |
$140,000 |
|
Building rent |
50,000 |
|
Utilities |
15,000 |
|
Spoilage |
375 |
|
Total |
$205,375 |
During May, Henderson manufactured 10,000,000 cartons. The amount of the overhead cost pool allocated to each carton is:
$205,375 / 10,000,000 cartons = $0.021 per carton
