Definition
In management accounting, an allocation base is a metric or value that is used to distribute indirect costs to cost objects. A cost object can be a product, service, project, or any activity. The allocation base ensures that costs are allocated fairly and accurately, reflecting their actual usage and consumption.
Traditional Costing System
In traditional costing systems, there is usually a single allocation base for each cost object. Common allocation bases in traditional costing include:
- Direct labor hours
- Machine hours
- Direct labor cost
Activity-Based Costing (ABC)
In an Activity-Based Costing (ABC) system, there can be multiple allocation bases, each corresponding to different activities. For example, an activity might be:
- Setting up machinery
- Quality inspections
- Assembly
Each of these activities would require a different allocation base. Measures commonly used in ABC systems are also known as activity measures or cost drivers.
Examples
-
Manufacturing Overhead Allocation:
-
Traditional Costing: Manufacturing overhead might be allocated based on direct labor hours. If $100,000 of overhead is to be allocated and a total of 10,000 labor hours are worked, each product would be allocated $10 of overhead per labor hour.
-
Activity-Based Costing: Manufacturing overhead is allocated based on multiple activities such as machine setup times, inspection hours, and assembly time. Each activity would have its own allocation base.
-
-
Service Industry Cost Allocation:
- Traditional Costing: Expenses might be allocated based on billable hours.
- Activity-Based Costing: Different activities like client onboarding, consultation, and implementation each have distinct bases such as hours spent in onboarding, number of consultative sessions, and projects implemented.
Frequently Asked Questions (FAQs)
What is an allocation base in cost accounting?
An allocation base is a measure or value used to allocate indirect costs to cost objects. It can be direct labor hours, machine hours, direct costs, or other measurable inputs.
How does an allocation base differ in traditional and activity-based costing systems?
In traditional costing, typically one allocation base is used per cost object, whereas in activity-based costing multiple allocation bases, aligned with specific activities, can be used.
What is a cost driver?
A cost driver, also known as an activity measure, is a factor that causes changes in the cost of an activity. Cost drivers in ABC systems are used as allocation bases.
Why is the allocation base important?
The allocation base is crucial for ensuring that costs are accurately distributed to cost objects, preventing cost distortion and aiding in better financial decision-making.
Can the allocation base be changed?
Yes, businesses can adjust their allocation bases based on changes in production processes, activities, or the costing approach they adopt.
