Activity Based Costing: Definition, Advantages, and Implementation

This presentation provides an overview of Activity Based Costing (ABC) and its advantages over traditional costing systems. It explains the concept of ABC, how it differs from traditional costing, and its implementation process. The presentation also covers the advantages and disadvantages of ABC, motivations for its introduction, and areas of improvement. References from various sources are included.

Activity Based
Costing

 During the mid 1980, it was felt that
absorption costing has certain limitations
 The absorption costing is introduced when
companies manufactured only few products
and it is easy to allocate the indirect costs
 The limitation of absorption has to the
introduction of the Activity based costing
(ABC) model
Origin of ABC

 As per definition provided by the CIMA for
ABC Costing:
◦ As per CIMA, activity based costing means an
approach used in management accounting
◦ It is introduced to monitor various activities within
the organization
◦ It allocate the resources to each activity on the
basis of the resource actually used by the
particular activity
◦ Though using the activity based costing actual
cost of each product can be easily calculated
ABC Costing (Definition and Concept)

 Mainly three main differences between the
ABC costing and traditional costing
 Through use of ABC costing both
manufacturing and non manufacturing cost
can be assigns to the product
 All types of manufacturing cost that is assigned in
traditional costing is not assigned in ABC Costing
 ABC uses more than one cost pool to allocate the
cost while traditional use only one cost pool to
allocate the cost
How ABC differ from the traditional Costing
system

 Advantages
◦ Activity based costing helps in providing the
accurate costing of products and services
◦ Overhead costs are divided to the various
products and services in the systematic manner
◦ The activity based costing also integrated with six
sigma technology to further improve the costing
system
◦ It helps in benchmarking of other products
Advantages of Activity based costing

 Disadvantages
◦ Big investment is required at the initial stage of
implementation of ABC costing model
◦ The maintenance cost of the ABC costing model is
very high and it requires frequent change to the
system
Disadvantages of Activity based costing

 Activity Based Costing (ABC) use in
manufacturing organizations is more over
the traditional cost accounting systems
 The most prominent example from the
manufacturing industry adopting the use
of ABC costing is General Motors (GM)
 The company uses ABC in estimation of
energy consumption according to
difference schedule of production
Motivations for ABC Introduction

 Used in accurate prediction of different
operations costs such as equipment, labor
and materials
 Help in achieving more realistic results
about the operational cost
 Beneficial in estimating the cost of any
additional activity such as environmental
factors
Implementation of ABC

 Can be used by GM only for identification
and allocation of overhead costs
 Could be used by GM only for identification
and allocation of overhead costs
 Identification of different areas for process
improvement and reducing the waste
generation
 Removal of Non-Value Adding Activities
Area of Improvement

 Necessary for GM to identify the non-value
adding activities to reduce the waste
generation
 Identification of the resources consumed by
the cost objects
 Enabling the company to develop actions
plans for reducing the cost involved in
production
Requirement of Improvement

 The area of improvement identified in the
company through the use of ABC is
proposed to be implemented in the
management accounting area
 Gaining an in-depth understanding of the
actual cost of good and services produced
 Use in management accounting area to
accurately identify activities consuming
large resources
