What is cost and its types?
What is Cost?
Cost is the sacrifice made, usually measured by the resources given up, to achieve a particular purpose. A sacrifice made in order to obtain some goods or services
- Costs are not always Expenses.
- Some costs are Assets, other costs are Expenses
- Expenses are Expired (Used up) Costs
Eventually, costs will become expenses.
Explanation
Cost measurement and allocation are a significant aspect of financial and management accounting. Cost measurement and allocation techniques are used not only to assign incurred costs to products or services but also to plan future activities.
In accounting, the term cost has a variety of meanings and a variety of cost concepts and measurement techniques are needed for internal planning and control.
The purpose of this article is to analyze the cost classifications and behavior patterns that are widely used in management accounting. Such an analysis would specifically help the management accountant specifically when he is supplying information for planning and decision-making purposes.
Types of cost
Cost may be defined as the amount measured in terms of money, paid in consideration of goods and services received or to be received. Accountants and managers use many different cost concepts and these different costs are used for different purposes. It is the classification of cost which indicates to the managers how the term is being used and whether they can do anything about the cost or not. Below are important types of cost.
Product cost
It is cost assigned to goods either purchased or manufactured for resale. Costs that are incurred for
producing or buying a product. Product costs are initially identified as part of the inventory on hand. (Raw materials, Work-in-process, Finished goods).
Inventoriable cost
It is another name for product cost, and it is stored as the cost of inventory until the goods are sold. Become expenses (Cost of goods sold) when the product is sold.
Period cost
Period costs are expensed during the time period in which they are incurred. Costs that are treated as expenses of the period in which the costs are incurred.
Expense
An expense is the consumption of assets for the purpose of generating revenue.
Direct cost
Cost that can be traced to specific segments of operations
Indirect cost
Cost that cannot be identified with particular segments. Common costs, Shared by multiple segments.
Example:
Segments = Plastic chairs (P) & Wood chairs (W)
Manufacturing cost
Product costs consisting of:
Direct material (DM)
Direct labor (DL)
Manufacturing overhead (MOH, OH)
Manufacturing cost formula:
Manufacturing costs = DM + DL + MOH
Direct material (DM)
It is raw material that is physically incorporated into the finished product.
Direct labor cost
It is the cost of salaries, wages, and fringe benefits for personnel who work directly on the manufactured products.
Manufacturing overhead
Manufacturing costs other than direct material and direct labor costs.
- Indirect material
These are required for the production process but do not become an integral part of the finished product. - Indirect labor
It is the cost of personnel who do not work directly on the product. but whose services are necessary for the manufacturing process.
Conversion cost
Conversion costs are direct labor costs plus manufacturing-overhead costs.
Prime costs
These are the costs of direct material and direct labor.
Non-manufacturing cost
Period costs (expenses) incurred in and Administrative activities.
Variable cost
A variable cost changes in total in direct proportion to a change in the level of activity.
Fixed cost
It does not change in total as activity changes.
Marginal cost
Extra cost incurred in producing an additional unit is called marginal cost.
Incremental cost
These types of costs are the difference between costs for the corresponding items under each alternative
being considered. For example, incremental cost increasing output from $1 000 to $1 100 units per week is the additional cost of producing an extra 100 units per week.
Difference between marginal and incremental cost
The main difference is that marginal cost represents the additional cost of one extra unit of output whereas incremental cost represents the additional cost resulting from a group of additional units of output.
Sunk cost
These are the costs that have been created by a decision made in the past and that cannot be changed by any decision that will be made in the future. Written down values of any asset previously purchased are the examples of sunk costs.
Opportunity cost
It is a cost that measures the opportunity that is lost or sacrificed when the choice of one course of action requires that an alternative course of action be given up. It is important to note that opportunity cost only applies to such resources that have some alternative uses. If no alternative use of resources exists then the opportunity cost is zero.
Cost of goods sold
It is the expense measured by the cost of the finished goods sold during a period of time.
Work in process
Partially completed products not yet ready for sale.
Finished goods
Completed goods available for sale.
