2 Advanced Costing Methods Flashcards
What are three reasons for development of ABC?
- Overheads used to be small in relation to other costs in traditional manufacturing
- Overheads are now a larger proportion of total costs in modern manufacturing
- The diversity and complexity of products has increased.
What does ABC establish?
Separate cost pools for support activities such as material handling. As the costs of these activities are assigned directly to products through cost driver rates, reapportionment of service departments is avoided
How does ABC charge overheads to products?
Cost drivers as absorption bases (I.e. Number of orders, or the number of despatches)
How does absorption costing charge overheads to products?
Labour or machine hours
What does ABC costing highlight?
What causes costs to increase
What is a cost pool?
A cost pool is an activity which consumes resources and for which overhead costs are identified and allocated
For each cost pool, there should be a ?
Cost driver
What is a cost driver?
A cost driver is a factor that influences (or drives) the level of cost.
What are the five steps for calculating the full production cost?
- Group production overheads into activities, according to how they are driven.
- Identify cost drivers for each activity, i.e. what causes these costs to be driven.
- Calculate OAR for each activity
- Absorb the activity costs into the product.
- Calculate the full production cost/and or the profit or loss.
What are the advantages of ABC? (7)
- More accurate cost per unit. As a result, pricing, sale, strategy, performance management and decision making should be improved.
- Much better insight into what drives overhead costs
- ABC recognises that overhead costs are not all related to production and sales volume.
- It can be applied to derive realistic costs in a complex business environment.
- ABC can be applied to all overhead costs, not just production overheads.
- ABC can be used just as easily in service costing as in product costing
- Overhead costs can be controlled by managing cost drivers.
What are the disadvantages of ABC? (5)
- ABC will be of limited benefit if the overhead costs are primary volume related or if the overhead is a small proportion of the overall cost.
- It is impossible to allocate all overhead costs to specific activities
- The choice of activities and cost drivers may be inappropriate
- ABC can be more complex to explain to the stakeholders of the costing exercise.
- The benefits obtained from ABC might not justify the costs
What are the four main drivers for introducing ABC?
Public responsibility, public accountability, resource allocation within organisations and helping managers to manage.
What is public responsibility?
Responsible public organisations must have tight control of running costs at a time when resources provided by central government are strictly limited
What is public accountability?
Many organisations are being challenged as to whether or not they spend tax payers money wisely and feel a need to demonstrate when the questions are asked
What is resource allocation within organisations?
There have been concerns in many organisations as to whether the services provided had an equitable distribution of scarce resource - or whether those who shouted the loudest got the resource
What is total quality management?
continuous improvement in quality, productivity and effectiveness through a management approach focusing on both the process and the product
What are six fundamental features of total quality management?
- Prevention of errors before they occur
- Importance of total quality in the design of systems and products
- Real participation of all employees
- Commitment of senior management to be cause
- Recognition of the vital role of customers and suppliers
- Recognition of the need for continual improvement
What is just in time?
Just in time is a pull-based system of production, pulling work through the system in response to customer demand. This means that goods are only produced when they are needed; eliminating large stocks of materials and finished goods
What is throughput accounting?
Throughput accounting aims to make the best use of a scare resource (bottleneck) in a JIT environment.
How do you measure throughput?
Throughput = sales revenue – direct material cost
