ABC COSTING
Before the implementation of ABC system, the following factors need to be considered:
It’s implementation needs very strong top management support.
Without leadership from top management, some managers may not see any reason to change.
Without top management support, the ABC implementation will be seen as unimportant,
There should be cross-functional involvement. Since ABC affects people across departments, it should involve these people and be fully supported by them. If the accounting department alone attempts to impose ABC on others, skepticism and resistance are inevitable,
A well designed ABC system requires intimate knowledge of many parts of an organization. This knowledge can only be learned from employees familiar with the various parts of an organization’s operations,
ABC data should be linked to how people are evaluated and rewarded. If traditional non-ABC data continues to be used to evaluate employee performance, it sends the signal that ABC data is unimportant and can even be ignored.
Identify the major activities in the organization,
Determine the significant factors or the costs drivers affecting the cost for each activity identified in 1,
Determine the activity cost and collect them into cost pools. A cost pool is a bucket in which costs that relate to a single activity are accumulated,
Prepare a total activity budget in each activity area. For example, total machine hours, total deliveries, total setups,
Calculate an activity cost driver rate,
Charge overheads to products based on their usage of the activities at the rates calculated in step 5 above.
The following are the basic steps to implement ABC system:Prepare management reports.
The activities are often identified and defined by interviewing the employees that work in the respective overhead departments.
The lengthy list of activities that emerges from this process is usually reduced to a handful by combining similar activities.
A common framework for combining activities in manufacturing companies is as follows:
Unit-level activities are performed each time a unit is produced. For example, providing power to run processing equipment would be a unit- level activity,
Batch-level activities are performed each time a batch is handled or processed, regardless of how many units are in the batch. For example, setting up equipment and shipping customer orders are batch-level activities.
Product-level activities relate to specific products and must be carried out regardless of how many batches are run or units produced and sold. For example, designing or advertising a product would be product-level activities,
Customer-level activities relate to specific customers and are not tied to any specific product. For example, sales calls and catalog mailings would be customer-level activities.
Organization-sustaining activities are carried out regardless of which customers are served, which products are produced, how many batches are run, or how many units are made. For example, heating a factory and cleaning executive offices are organization-sustaining activities.
When combining these activities, they should be grouped together at the appropriate level. Batch-level activities should not be combined with unit-level activities, and so on.
Furthermore, activities should only be combined within a level if they are highly correlated with each other.
Each combined group of activities forms what is called an activity cost pool which is defined as a “bucket” that accumulates costs related to a single allocation base.
Product-level activities relate to specific products and must be carried out regardless of how many batches are run or units produced and sold. For example, designing or advertising a product would be product-level activities,
Customer-level activities relate to specific customers and are not tied to any specific product. For example, sales calls and catalog mailings would be customer-level activities.

thanks for your useful notes
thankyou so much for your replies... with this response i m gonna share every topic with u very regularly soon... thx
Activity-Based Costing: The Necessity To Know The “True” Cost Of A Product
Unlike other traditional costing systems, one of the importance of activity based costing is to determine the “true” cost for a cost object which is a product, service or customer
Why is then the necessity to know the “true” cost of a product?
Some of the reasons includes the following:
To identify money makers/money losers;
To finding an economic break-even point;
To compare different options;
To discover opportunities for cost improvement;
To prepare and actualize a business plan and
To improve strategic decision making.
Interestingly, the aforesaid “true” products( e.g. total manufacturing costs) have only a minor importance in final market price determination which are more dependent on competitions and customer value.
Append below an illustration of a scenario on both Traditional Cost Accounting and Activity based costing
Under Traditional Cost Accounting:
Direct Cost:
Product A: requires 1 hour of direct labor
Direct labor cost per hour say:1 x$10/hour=$10
Demand for A =100 units
Product B requires 2 hours of direct labor
Direct labor cost per hour say 2 hours x$10/hour=$20
Demand for B=950 units
Overheads:
Total Overheads=$50,000
Total direct labor=1,000 hours
Overheads per direct labor hour=50,000/1000=$50/hour
Under Traditional Costing System:
Cost For Product A:
Direct cost=$10.00 Total overhead allocation= 1x$50=$50.00
Cost for Product B:
Direct cost=$20.00 Total overhead allocation: 2x$50=$100
Under Activity Based Costing methodology:
Identifying activities
Determine cost for each activity
Determine cost drivers
Collect activity data
Calculate product cost
Identifying activities:
Set-up
Machining
Receiving
Packing
Engineering
Determine cost for each activity:
Set-up$ 5,000
Machining$20,000
Receiving $ 5,000
Packing $ 5,000
Engineering $15,000
Determine cost drivers:
Set-up Number of Setups
Machining Machining Hours
Receiving Number of Receipts
Packing Number of Deliveries
Engineering Engineering Hours
4.Collection Of Activity Data:
Activity Cost($) Product A $ Product B $
Set-up 5,000 1 1,250 3 3,750
Machining 20,000 100 1,000 1,900 19,000
Receiving 5,000 1 1,250 3 3,750
Packing 5,000 1 1,250 3 3,750
Engineering 15,000 500 7,500 500 15,000
Total 12,250 45,250
Under Activity-based costing-
Overhead for Product A =$12,250/100=$122.50
Overhead for Product B=$45,250/950 =$ 47.63
product Costs Results Under TCA & ABC
Product A Product B
TCA:
Direct cost $10.00 $20.00
Overheads $50.00 $100.00
Total $60.00 $120.00
ABC:
Direct cost $ 10.00 $ 20.00
Overheads $122.50 $ 47.63
Total $132.50 $ 67.63
Using traditional cost methodology, it looks like Product A has a lower cost than Product B.
However, using ABC, on the contrary, management is able to see clearer that Product A is in fact has a higher cost than Product B.
Conclusion:
ABC is more accurate cost management system than Traditional cost accounting.
Traditional cost account is unable to calculate the “true” cost of a product.
