Activity-based budgeting
The rise of e-commerce, globalisation, and shorter product life-cycles are some of the
factors increasing competitive rivalry across many business sectors. Also, indirect costs
are becoming a higher percentage of total costs for many companies as technology and
automation investments become more crucial to success. Because of this, managers
need a deeper and more accurate understanding of the true cost of delivering their
goods or services. Activity-based budgeting (ABB) is a tool that helps with this and is
closely linked to activity-based costing (ABC), also in your syllabus.
Under an absorption costing system, indirect costs are pooled together and labelled
‘overheads.’ An overhead absorption rate is then calculated, based on a single driver –
for example, direct labour hours (which can be easily found via payroll records).
Overheads are then assigned to products on the basis of the overhead absorption rate
and direct labour hours per unit. This cost per unit can then be used for the budgeting
process.
ABB, in conjunction with ABC, focuses on understanding how overheads are consumed
by the production process. Overheads are analysed, and ABB then looks at costs from
the perspective of the activities that are required to satisfy the customer. Production and
non-production activities are measured and quantified, and then a cost per activity (or
cost per driver) is determined through detailed analysis of operations and costs. Once
the cost per driver is calculated, managers can then create a more accurate budget
based on departmental consumption of activities. ABB is essentially ABC in reverse.
Pros and cons
During an ABB/ABC exercise, ‘non-value adding’ activities can be identified – these are
activities which do not increase the customers’ perceived worth of the final product.
These activities can then be eliminated. Value-adding activities and processes can then
be automated or improved. Also, the budgeted costs and profit per product should be
more accurate as costs per driver are determined after detailed analysis. ABB helps
align value-added activities with objectives, reducing costs in the process.
However, there can be some disadvantages to using ABB. As stated above, ABB will
require detailed analysis of overheads and measuring of activities. This can be a
complex, costly and time-consuming project. If direct costs are more significant than
indirect costs, and if the product range is narrow, the costs might outweigh the benefits
of switching to ABB.

Toy Co manufactures toys for toddlers and children. They are a small company and
have a good reputation for producing high quality, innovative products. Their profit
margins have been consistently higher than competitors in the same industry.
However, profitability has been slowly dropping over the past two years due to
increasing overhead costs and the loss of several key customers because of shipping
errors and missed delivery dates. The management accountant believes there are nonvalue added activities which can be removed to improve efficiency and reduce costs,
and is considering the introduction of activity-based budgeting. He has decided to
initially analyse two popular products, the ‘Tod’ and the ‘Kid’.
Much of the production process is automated and occurs in batches. Orders are placed
by large retail chains and demand is relatively constant during the year.
Operational information for each product is as follows:
Tod
Kid
Quarterly demand (units)
30,000
36,000
Production batch size (units)
3000
1000
Order size (units)
