It is obtained by dividing the factory expenses associated with the machine for a given period by the number of hours worked by the machine during that period. In Thothadri, Nafeesa, and Jalalutheen’s seminal 2019 book entitled Cost Accounting, the machine hour rate is d…

Blanket Absorption Rate and Departmental Absorption Rate

Blanket Absorption Rate Blanket absorption rate is used in relation to the recovery or absorption of overheads. For ease and simplicity, a common absorption rate for overheads may be used across a factory for all jobs and units of production, irrespective of the department in which they were produced. This is known as the blanket absorption rate. A common absorption rate is not appropriate when a…

These methods apply to absorbing the factory overhead: (1) Units of Output Method Absorption of the factory overhead occurs based on the number of units manufactured. Dividing the overhead expenses by the number of units of output obtains the overhead rate. Formula Overhead rate = factory overhead of the department / number of units of output. Example If the factory overhead for department ‘A’ for…

Overhead rates that are established for the absorption of overheads may be divided into two parts: Actual Overhead Rate Pre-Determined Overhead Rate 1. Actual Overhead Rate The actual overhead rate is based on the actual amount of overhead to be absorbed and the actual quantum or value of the base selected (e.g., direct wages, cost of materials, machine hours, direct labor hours, etc.). The actual…

What is Under-absorption and Over-absorption of Overheads? Where the absorption of overheads is made using a rate based on actual data, the overhead absorbed must be equal to the actual overhead incurred. But where a pre-determined rate is used, there is generally a difference between the overhead absorbed and the overhead incurred. If the absorbed amount is less than the actual overhead, there is…
