UNIT IT 3: Overheads Distribution

BY: JYOTSNA KHAITAN

Direct and indirect expenses: 1.Direct expenses are expenses that can be directly identified with a specific cost unit or cost center. There are few examples of direct expenses but royalties paid to a designer or fees paid to a subcontractor for a specific job could be classed as direct expenses.

• Direct expenses are part of the PRIME COST of a product.

2.Indirect expenses cannot be directly identified with a specific cost unit or cost center.

• For example, the cost of renting a factory where shirts are manufactured is

classified as an indirect cost because it would be impossible to relate such costs to shirts only, if other clothes, such as dresses and suits were also made in the same factory.

• Indirect expenses are also known as OVERHEADS.

Inter-department service:

(As we did a practical question before the holidays; we learned how service department costs are Apportioned over other production departments.) In case service departments render services to each other, the service department costs are charged to each other on reciprocal

• basis. These costs are also called Reciprocal-costs.

The inter-service distribution of the reciprocal-costs can be done by using any of the three methods:

• 1. Simultaneous Equation method
• 2. Repeated Distribution method
• 3. Trial & Error method

(1) Simultaneous Equation method: In this method we construct simultaneous-equations to solve the problem of distribution of cost among themselves simultaneously. Question 1:

1,000 2,500 1,800 9)OVERHEAD RATES per hour {Total expenses ÷ Number Of hours} 1,663 ÷ 1,000 = 1.663 2,606 ÷ 2,500 = 1.042 1,731 ÷ 1,800 = 0.961

Simultaneous equations; Let X = total expenses of service department D to be apportioned And Y = total expenses of service department E to be apportioned Therefore; X = 630 + 20% of Y , And Y = 510 + 10% of X Solving the two equations simultaneously we get; X = 747 Y= 585

Calculations:

(2) REPEATED DISTRIBUTION METHOD:

According to this method the percentages given in the question are used and service department expenses are apportioned repeatedly, till the total costs of service departments are exhausted. Using the same question let us solve it with the repeated distribution method. The end result will tally with the results of simultaneous equation method.

(3) Trial & Error Method :

In this method the cost of one service center is apportioned to another service center plus the share received from the first cost center is again apportioned to the first cost center. This process is continued till the amount to be apportioned becomes nil.
