Answer:
The differences are as follows:
- In traditional costing, overheads are related to departments,
and are distributed accordingly. In Activity based costing,
overheads are grouped into activity cost pools and are then applied
according to activities.In other words, in traditional costing,
overheads are applied to production and service centres directly.
In Activity based costing, the overheads are related to activities,
and are then applied to the products.
- In traditional costing, time hours or units is the only cost
driver in all departments. In Activity based costing, activity wise
cost drivers are calculated.
- In traditional costing, costs are assigned to the cost units
such as products or jobs or hours. In Activity based costing, costs
are assigned to cost objects such as customers, products,
departments, etc.
- Activity based costing is more realistic than traditional
costing because costs are divided into activities.
