ACCA Job, Batch and Service Costing Notes by PW

Activity-Based Costing focuses on assigning overheads according to the activities consumed by products, while Target Costing starts with the target selling price and desired profit to determine the maximum allowable cost. Lifecycle Costing considers costs incurred throughout the different stages of a product's life, from development to decline.

Understanding the purpose and application of each technique can help you distinguish between different cost management approaches. The Alternative Cost Accounting Techniques PDF by PW supports revision of activity-based rates, cost pools, cost drivers, target cost calculations and the key stages of a product’s life cycle. 

Activity-Based Costing (ABC)

Activity-Based Costing (ABC) is an absorption costing technique that allocates overhead costs to products according to the activities involved in producing them. It focuses on the activities that cause costs to arise rather than applying the same overhead allocation basis to all products.

ABC is particularly useful when products or services consume different levels of activities and overhead costs form a significant part of total costs.

Cost Pools and Cost Drivers

A cost pool is a group of costs associated with a particular activity. Examples include costs related to machine setup, material handling and purchasing.

A cost driver is the factor that causes a cost pool to change. Common examples include:

• Number of machine setups

• Machine hours

• Number of purchase orders

• Number of material movements

The cost driver provides the basis for determining how much overhead should be assigned to a product.

Activity-Based Rate

The activity-based rate is calculated by dividing the cost contained in a cost pool by the total volume of its cost driver.

Activity-Based Rate (ABR) = Cost Pool ÷ Cost Driver Volume

The resulting rate can then be applied to the number of cost-driver units consumed by a product.

Activity-Based Costing vs Traditional Costing

Traditional costing may allocate overheads using a single basis, such as direct labour hours or machine hours. This approach averages overhead costs across products using the same allocation basis.

ABC uses multiple activity-based rates. Each cost pool is linked to an appropriate cost driver, allowing overheads to be allocated according to the activities consumed by different products.

ABC can be particularly useful in manufacturing or service environments where overhead or fixed costs are high and different products or services use activities in different proportions.

Target Costing

Target Costing is a cost management technique used to determine the maximum cost at which a product can be produced while achieving the required profit.

It begins with the expected selling price and desired profit rather than starting with the existing cost of production. The difference between these two amounts establishes the target cost.

Target Cost Formula

Target Cost = Target Selling Price − Desired Profit

For example, if the target selling price of a product is Rs. 2,000 and the desired profit is Rs. 500, the target cost would be Rs. 1,500.

This means the product needs to be designed and produced within the Rs. 1,500 cost limit to achieve the desired profit at the target selling price.

Lifecycle Costing

Lifecycle Costing tracks and accumulates the costs associated with a product throughout its entire life. It considers costs beyond the manufacturing stage, beginning with product development and continuing through the later stages of the product's life.

The purpose is to assess overall product profitability by considering total lifetime revenue and costs rather than focusing only on costs incurred during production.

Stages of Product Life Cycle

A product typically passes through five main stages: development, introduction, growth, maturity and decline. The level of expenditure, revenue and profitability can vary across these stages.

Development

The development stage includes activities such as product design, initial setup and prototyping.

Revenue has generally not yet been generated, while expenditure can be high. This can result in negative cash flow during the development stage.

Introduction

The introduction stage begins when the product enters the market.

Sales volume may initially be low, while marketing and advertising costs can be significant. As a result, the product may generate limited profitability or negative cash flow.

Growth

During the growth stage, demand and market adoption increase.

Sales and profits can rise as the product gains market acceptance. Higher production volumes may also provide economies of scale and contribute to positive cash flow.

Maturity

The maturity stage is characterised by high market adoption and relatively stable demand.

Sales growth may begin to plateau, while profitability can remain high. Product improvements or updates may be required to maintain market position.

Decline

During the decline stage, customer interest and sales decrease.

Falling sales can reduce profits and may eventually result in losses. The product may ultimately become obsolete or be discontinued.

Alternative Cost Accounting Techniques PDF

The Alternative Cost Accounting Techniques PDF by PW focuses on the key concepts involved in Activity-Based Costing, Target Costing and Lifecycle Costing. It covers cost pools, cost drivers, activity-based rates, target cost calculations and the different stages of a product's life cycle.

Why Use PW’s Alternative Cost Accounting Techniques Notes for Your Preparation?

The Alternative Cost Accounting Techniques notes by PW focuses on Activity-Based Costing, Target Costing and Lifecycle Costing. These techniques help you understand activity-based overhead allocation, determine the maximum allowable cost from the target selling price and desired profit, and assess costs across different stages of a product’s life cycle. 

Understand Activity-Based Costing

Activity-Based Costing uses cost pools and cost drivers to assign overheads according to the activities consumed by products. Revising ACCA Management Accounting (MA) alongside Activity-Based Costing can help you connect overhead allocation with wider Management Accounting concepts. 

Understanding activity-based rates and comparing ABC with traditional costing can also help you identify how multiple cost drivers provide a more specific basis for assigning overheads.

Revise Target Costing

Target Costing starts with the target selling price and desired profit to determine the maximum allowable cost. Revising ACCA MA Formula List can help you practise the Target Cost formula and other costing calculations. Understanding the relationship between selling price, desired profit and target cost can also help you apply the technique to product pricing decisions.

Understand Product Life Cycle Stages

Lifecycle Costing considers costs across development, introduction, growth, maturity and decline. Revising these stages alongside the ACCA MA Syllabus can help you connect Lifecycle Costing with the wider costing and Management Accounting topics included in your preparation.

Analyse Costs Beyond Production

Lifecycle Costing considers costs such as design and development, advertising, production and training rather than limiting cost analysis to manufacturing. Reviewing ACCA Management Accounting preparation concepts can help you understand how cost analysis supports planning, decision-making and cost control beyond individual production expenses.

Activity-Based Costing, Target Costing and Lifecycle Costing provide different approaches to understanding and managing costs in Management Accounting. Revising their key concepts, formulas and applications can help you distinguish between overhead allocation, target cost determination and product life cycle analysis. 

The Alternative Cost Accounting Techniques PDF by PW can support your revision by helping you review these concepts and their related calculations in one place.
