Definition of OverheadsDefinition of Overheads
The CIMA defines overhead cost as “the The CIMA defines overhead cost as “the total cost of indirect materials, indirect total cost of indirect materials, indirect labor and indirect expenses. In short, it is labor and indirect expenses. In short, it is the cost of materials, labor and expenses the cost of materials, labor and expenses that cannot be economically identified with that cannot be economically identified with specific saleable cost unit. specific saleable cost unit.

Steps on Overhead AccountingSteps on Overhead Accounting
The various steps in an overhead The various steps in an overhead accounting are:accounting are:
Collection of overhead details Collection of overhead details Distribution of overhead to cost centers Distribution of overhead to cost centers Reapportionment of service department Reapportionment of service department
costs to production departments costs to production departments

Absorption of OverheadsAbsorption of Overheads
““Process of allocating the overhead Process of allocating the overhead expenses to the cost centers/cost units is expenses to the cost centers/cost units is known as overhead absorption” known as overhead absorption”
Absorption ratesAbsorption rates
Actual rate Actual rate
Predetermined rate Predetermined rate
Moving average rate Moving average rate
Blanket and multiple rates Blanket and multiple rates
Rate per unit of productionRate per unit of production
OH rate = OH rate = Budgeted overhead expensesBudgeted overhead expenses Budgeted productionBudgeted production
Features: Features: • Simple /easy to use Simple /easy to use • Suitable for extractive industries Suitable for extractive industries
Direct Wages MethodDirect Wages Method OH rate = OH rate = Budgeted overhead expensesBudgeted overhead expenses
Direct wages Direct wages Advantages:Advantages:
• Consideration of time factor Consideration of time factor • Stability of labor rates Stability of labor rates • Proportional charge to production Proportional charge to production • Easy availability of data Easy availability of data • Most appropriate in certain situations Most appropriate in certain situations
Limitations:Limitations: • Not related to efficiency of workers Not related to efficiency of workers • Consideration of time factor (piece rate basis) Consideration of time factor (piece rate basis) • Ignores contribution by other factors of production Ignores contribution by other factors of production • No distinction between fixed and variable expensesNo distinction between fixed and variable expenses
Production hour method Production hour method OH rate = OH rate = Budgeted overhead expensesBudgeted overhead expenses
Total productive hours of direct labor Total productive hours of direct labor Advantages:Advantages:
• When job is labor-oriented When job is labor-oriented • Uniform time for various jobs Uniform time for various jobs • No impact on rate by the method of wage No impact on rate by the method of wage
payment/grade/rate of workers payment/grade/rate of workers Limitations:Limitations:
• Faulty distribution of overhead Faulty distribution of overhead • Not suitable where piece rate system is used Not suitable where piece rate system is used • Expenses not related to labor hours are ignored Expenses not related to labor hours are ignored • No clear distinction between types of labor/costs/workers No clear distinction between types of labor/costs/workers
Machine hour rate method Machine hour rate method OH rate = OH rate = Total running expensesTotal running expenses
Number of working hours for the machine Number of working hours for the machine Advantages:Advantages:
• Scientific/practical/accurate Scientific/practical/accurate • Comparison of relative efficiencies Comparison of relative efficiencies • Decision making by the management Decision making by the management • Detection of idle time Detection of idle time
Limitations:Limitations: • Higher cost Higher cost • Not useful when blanket rate is used Not useful when blanket rate is used • Inaccurate results if use of labor is equally important Inaccurate results if use of labor is equally important • Doesn’t consider expenses that are not proportionate to working Doesn’t consider expenses that are not proportionate to working

Under absorption/Over absorptionUnder absorption/Over absorption
The OH costs are fully recovered from The OH costs are fully recovered from production, if actual rate method of production, if actual rate method of absorption is adopted. If the OH rate absorption is adopted. If the OH rate absorbed is less than the overheads absorbed is less than the overheads incurred, it is called as under absorption of incurred, it is called as under absorption of overheads. overheads.
If the OH rate absorbed is more than the If the OH rate absorbed is more than the actual overheads incurred, it is known as actual overheads incurred, it is known as over absorption of overheads. over absorption of overheads.
Accounting of Under absorption Accounting of Under absorption and Over absorptionand Over absorption
