Consequently, this allocation process helps companies include these indirect costs to use in several areas. In standard costing systems where overheads are absorbed on direct labour hours, companies sometimes analyse the fixed overhead volume variance into capacity and volume efficiency elements. For cost centres that are labour intensive, labour hours are a more appropriate basis. However, nowadays, most companies use machinery for their tasks.
It is used in mechanized production environment where machine time is vital and limiting factor. (b) It is more appropriate in a labour intensive cost centre where proper records are maintained for time booking. (1) The cost of materials is often subject to considerable fluctuations which will not be accompanied by similar fluctuations in overhead.
The distribution of the accumulated overhead cost of a production department amongst its cost units is known as overhead absorption. Using a departmental overhead rate is beneficial because it ensures that all jobs and Units of Production are charged with their fair share of overheads. It also enables the identification of which department is responsible for incurring a particular overhead expense. A common absorption rate is not appropriate when a factory has many departments, or when the jobs or units of production do not spend an equal amount of time in each department.
(iii) Where the cost of materials forms a larger part of prime cost, the time factor will be ignored. Certain factors are considered for choosing a particular and appropriate base for absorption of overheads, but final choice is a matter of judgement arid common sense. It is rare for applied overheads to agree with actual overheads; a difference is always likely to exist. If the absorbed amount exceeds the actual overhead, the difference is termed overapplied overhead. This method is suitable for labor-intensive industries in which manual labor is a dominant factor in production.
Consequently, an immediate write-off is usually limited to smaller variances, while the latter method is used for larger variances. This formula can also be used in other industries – the only thing needed to adjust is to replace the number of implementations with the number of other produced units. Then, use the cost allocation formula to determine what costs should a given project cover.
If suitable basis is not followed, the calculation of machine from rate is misleading. The idle time of the machine is disclosed through analyzing under absorption of overhead. It is very easy to calculate machine hour rate well in advance. This method is not suitable if the workers are paid on piece rate basis. The reason is that overhead depends upon the time instead of output. There is a direct relationship between time factor and direct wages.
For example, if your business incurs overhead costs based on the number of direct labor hours worked, then the allocation base could be the total number of labor hours worked by all employees. No – absorbed overhead is only calculated for additional, indirect costs affecting the project budget. Direct costs, order of liquidity financial definition such as direct labor hour, production costs, machine hours (in production industries) or manufacturing costs are not included in the equation. Overhead absorption is the amount of indirect costs assigned to cost objects. Indirect costs are costs that are not directly traceable to an activity or product.
The graph shows that absorption costing takes what is a fixed cost ($10,000 per year), and converts it to a cost per unit of activity, effectively treating it as a variable cost ($10 per unit). Graph 2 shows this FOAR being used to absorb overhead into production, in a situation where output and expenditure are as budgeted. (3) It is inaccurate when manual labour plays equally important role in production. (3) When piece rate systems are used for payment, labour working hours may not be available in records.
Thus our 1,200 units produced should have taken 6,000 hours (1.200 x 5 hours, and should have cost $12,000. (6,000 hours x $2 standard FOAR). Consequently a further favourable variance of $1,200 is recorded for efficiency reasons (the company was efficient because it produced 6,000 standard hours worth of product in 5,400 hours). However, output in a standard costing system production will be costed at standard cost. This means that when production enters finished goods we will value it as if it was made at standard cost.
A fixed cost is one that remains steady, regardless of whether the business is delivering one unit or 100,000 units. These overheads can be easier to budget for, as they do not typically fluctuate from one financial period to the next. However, higher fixed costs can create a larger and less flexible cost burden that must be covered before a business makes a profit. Now a day, machine, production is getting importance and, therefore, the overhead may be absorbed on the basis of machine hour rate. If automatic and semi-automatic machines are used in the manufacturing process, machine hour rate is applied in the case of overhead absorption. It is more realistic because machine hour rate is applied only when the machine is used in production of the job or cost unit.
