# Allocation and Apportionment of Overheads

• Charging to overhead to specific department

• If OH relate to more than one department then they are apportioned on suitable basis
• Apportionment is made on reasonable basis like area, number of employees

SECONDARY APPORTIONMENT

• Service departments like canteens offer services but do not have production
• Cost of these services center is charged to production centers
• Secondary apportionment can be made by three ways: elimination, repeated distribution, algebraic methods

## Methods for secondary apportionment of service overhead

When service department is giving its services to other service departments and production departments then following method are used

• Repeated Distribution Method
• Simultaneous Equation Method → When there are only two service departments
• Direct Method
• Step Method

#### REPEATED DISTRIBUTION METHOD

If service department apportion its cost to production departments and other service departments and that other service departments likewise apportion their costs to production departments and apportion back to other service departments until total cost of both service departments are apportion to the production departments.

 Particulars Production department 1 Production department 2 Service department  S1 Service department  S2 BUDGETED OVERHEAD XXXX XXXX XXXX XXXX Allocation of S1 XXXX XXXX (XXXX) XXXX Allocation of S2 XXXX XXXX XXXX (XXXX) Reallocation of S1 XXXX XXXX (XXXX) −−−−− Total Budgeted Overhead XXXX XXXX −−−−− −−−−−

#### ALGEBRIC METHOD (SIMULTANEOUS EQUATION METHOD)

Simultaneous equation method is used when only there are only two service departments

In this method we use equation to allocate the service departments’ expenses to production departments.

For Example

 Particulars Production Department Service Department A B X Y X Allocation 50% 30% − 20% Y Allocation 40% 50% 10% − EXPENSES 500,000 400,000 100,000 60,000

Equation for service Departments

X = 100,000 + 0.1 Y

Y = 60,000 + 0.2 X

#### DIRECT METHOD

If service department apportion its cost only to production Department.

Recognition of Direct Method (When Statement is used)

Service department apportion their cost only to production departments

#### Step method

If first service department apportion its cost to production department and other service department and that other service department apportion its cost to production department and does not reapportion its cost to first service department or does not apportion back its cost to first service department.
