Splits the $1,000 based on number of setups (the actual activity). Pens need 1 setup (cost $100), Watches need 9 setups (cost $900). Result: Watches are correctly assigned higher costs because they consume more setup activity.
Unlike traditional systems that often apply a "one-size-fits-all" overhead rate based on volume, ABC recognizes that different products consume resources in vastly different ways. Core Components of ABC
Unlike traditional costing methods that allocate overhead based on a single volume metric (like labor hours or machine hours), ABC recognizes that specific products or services may consume resources differently. It assigns costs based on the "cause and effect" relationship between activities and costs. activity based costing definition
Instead of broadly spreading costs (like rent or electricity) evenly across all products, ABC identifies the actual activities driving those costs (like machine setups, quality inspections, or order processing) and allocates expenses based on how much of each activity a product uses.
| Term | Definition | Example | | :--- | :--- | :--- | | | The final product, service, or customer you want to cost. | A specific smartphone model, a car repair, or a bank account. | | Activity | Any event, task, or unit of work with a specific goal. | Setting up a machine, processing a purchase order, testing a component. | | Cost Driver | The factor that causes the cost of an activity to increase or decrease. | Number of machine setups, number of purchase orders, number of quality tests. | Splits the $1,000 based on number of setups
Implementing ABC involves a two-stage allocation process to ensure the "true" cost of a product is captured:
Imagine a factory that makes and Watches (low volume, complex) . Their total overhead is $1,000 for machine setups. Instead of broadly spreading costs (like rent or
Imagine a factory makes two types of chairs: (mass-produced) and Custom (highly specialized).
Splits the $1,000 based on production volume . If Pens make 90% of units and Watches 10%, Pens get $900, Watches get $100. Result: Pens are overcosted; Watches are undercosted.
