Cost object is anything for which cost data are desired- including products, customers, jobs, and organizational subunits.
Cost driver is factor that affects the costs associated with an activity.
Product costs include all costs involved in acquiring or making a product. Period costs are all the costs that are not product costs.
Fixed cost is a cost that remains constant, in total, regardless of changes in the level of activity. Fixed costs are not affected by changes in activity. Variable cost is a cost that varies, in total, in direct proportion to changes in the level of activity.
Direct cost is a cost that can be easily and conveniently traced to a specified cost object.
Indirect cost is a cost that cannot be easily and conveniently traced to a specified cost object.
Incremental cost is a difference in costs between any two alternatives Common cost is a cost that is incurred to support a number of cost objects but cannot be traced to them individually.
Relevant costs are costs that differ between alternatives. Irrelevant costs can be ignored-saving decision makers tremendous amounts of time and effort
Dual allocation (sometimes called departmental)-
Activity-based allocation is a costing method that is designed to provide managers with cost information for strategic and other decisions that potentially affect capacity and therefore “fixed” as well as variable costs.
