ACC210 Ch3 Set 1 REVERSED Flashcards
the relationship between a cost and the level of activity or cost driver
Cost behaviour
the process of determining the cost behaviour of a particular cost item
Cost estimation
using knowledge of cost behaviour to forecast the level of cost at a particular level of activity
Cost prediction
a cost driver that assumes that costs are driven, or caused, by the volume of production (or sales)
Volume-based cost driver
a cost driver not directly related to production volume
Non-volume-based cost driver
1) unit 2) batch 3) product 4) facility
Four distinct levels of costs & cost drivers?
a unit of work performed within the organisation
Activity
costs relating to activities that are performed for each unit produced
Unit level costs
costs relating to activities that are performed for a group of product units, such as a production batch or a delivery load
Batch level costs
costs relating to activities that are performed for specific products or product families
Product level costs (product-sustaining)
the costs incurred to support the business as a whole; not caused by any particular product
facility level costs (facility-sustaining)
the underlying factors that cause activities to be performed and their costs to be incurred
Root cause cost drivers
- reasons for analysing cost behaviour: to provide estimates of cost behaviour for cost prediction - timeframe for analysing the cost behaviour: short term, as costs will be predicted for the budget period (i.e. the coming year) - availability of data on cost drivers - any other uses for the information on cost behaviour
Assessing the costs & benefits of each driver?
- variable costs - fixed costs - step-fixed costs - semivariable costs - curvilinear costs
Cost behaviour patterns
Y = a + bX Y= total cost a= fixed cost component (the intercept on the vertical axis) b= variable cost per unit of activity (the slope of the line) X= the level of activity
Linear cost functions - Total cost =
