Activity based costingActivity based costing
There is no true cost of a good or service unless a There is no true cost of a good or service unless a company manufactures a single product or provides a company manufactures a single product or provides a single service. Otherwise, accountants must allocate single service. Otherwise, accountants must allocate costs for all products and servicescosts for all products and services
Allocating service department costAllocating service department cost Companies normally allocate service department Companies normally allocate service department
costs to production department. Accordingly goods costs to production department. Accordingly goods and services reflect the total full cost of production.and services reflect the total full cost of production.

models or unit based drivers are allocations based on labor models or unit based drivers are allocations based on labor hours, machine hours and material costs. Cost drivers are hours, machine hours and material costs. Cost drivers are factors that cause an activity to occur.factors that cause an activity to occur.

For the traditional volume based cost allocation, For the traditional volume based cost allocation, inspection costs are allocated on machine inspection costs are allocated on machine hours. Total machine hours are budgeted as hours. Total machine hours are budgeted as followsfollows
3 × 10 product A units + 4 × 20 product B 3 × 10 product A units + 4 × 20 product B units = 110 machine hours. This will yield the units = 110 machine hours. This will yield the following ratefollowing rate
