Costing is any system for assigning costs to an element of a business. Costing is typically used to develop costs for any or all of the following:
- Distribution channels
- Geographic regions
- Product lines
- Entire companies
Costing may involve only the assignment of variable costs, which are those costs that vary with some form of activity (such as sales or the number of employees). This type of costing is called direct costing. For example, the cost of materials varies with the number of units produced, and so is a variable cost.
