One can understand the cost accounting properly only after knowing various types of cost. Hence, the understanding of types of cost enables proper application of cost accounting principles. Therefore, certain types of cost are briefly explained below.
1. Historical Cost
It is the post mortem of cost, which is already incurred. This type of cost reports the past events. If the time lag between the cost incurred time and reporting time is very short, quality decision may be taken. If not so, these costs are irrelevant for decision-making.
2. Future Cost
These types of costs are expected and incurred in the days to come.
3. Replacement Cost
Replacement cost is the cost required to replaced any existing asset at present.
4. Standard Cost
Standard cost is a scientifically predetermined cost, which is arrived at assuming a specific level of efficiency in material utilization, labor and indirect expenses.
5. Estimated Cost
Estimated cost is an assessment of what will be the cost approximately. It is based on the past experience and adjusted according to the expected future changes.
Indirect Cost is the cost, which cannot be easily or directly identified to the unit of output or to the segment of a business operation.
11. Fixed cost
Fixed cost is otherwise called fixed overhead and period cost. A cost, which is incurred for a specific period and does not get affected by fluctuations in the levels of activity (output or turnover). For example Rent, Salaries and the like.
12. Variable Cost
Variable cost is the cost, which is varying or fluctuating according to the levels of activity (output or turnover) in direct proportion.
13. Opportunity Cost
Opportunity is the value of a benefit sacrificed in favor of an alternative course of action.
14. Imputed Cost
Imputed cost is otherwise called Notional Cost and Hypothetical Cost. A cost that has not involve cash outflow from the business organization. It does not appear in the financial records but relevant to the decision-making.
For example: Interest on Capital. CIMA defines notional cost as,
the value of a benefit where no actual cost is incurred.
15. Programmed Cost
A cost which is incurred under any specific programme of an organization is called programmed cost. This is reflecting top management policies and decisions.
16. Controllable Cost
Controllable cost is the cost, which can be influenced by budget holder. In other words, a cost may be controllable by managerial supervision.
17. Non-Controllable Cost
Non-controllable cost is the cost that cannot be easily controllable at any level of managerial supervision.
18. Joint Cost
Joint cost is the cost of a process, which results in producing more than one main product.
A cost can be shifted to future with little or no effect on the efficiency of current operations is postponable cost.
21. Out of Pocket Cost
Out of pocket cost is the cost which results in cash outflow from the business organization due to a particular managerial decision.
22. Differential Cost
Differential cost is the difference of cost between the total costs of two alternatives that are calculated to assist decision-making.
23. Conversion Cost
Conversion cost is also called production cost. Direct material cost is not included in the production cost. It is the cost incurred for converting the raw material into finished product. In other words, it is the combination of direct labor, direct expenses and factory overhead.
24. Capacity Cost
Capacity cost is an alternative term used for fixed cost. It is the cost of providing facilities through a system for a particular period. The capacity cost is classified into two categories. They are Standby Cost and Enabling Cost.
25. Standby Cost
Standby cost is the cost that is to be incurred continuously even though the operations or facilities are shutdown temporarily. For example, Depreciation.
26. Enabling Cost
Enabling cost is the cost that is not to be incurred if the operations or facilities are shutdown temporarily.
27. Committed Cost
Committed cost is a fixed cost of the company resulted from the earlier decision of the management. For example: Insurance Premium. The amount of insurance premium cannot be controlled at present on a short run basis.
28. Avoidable Cost
Avoidable cost is the specific cost of an activity or a sector of a business that can be avoided if that activity or sector is not in operation.
29. Decision Driven Cost
Decision Driven cost is the cost incurred by the company due to its policy decision up to the stage of altering such decision. It does not vary with changes in the level of output or operational activities.
30. Marginal Cost
It is the cost of one more unit of product or service, which can be avoided if that unit is not produced or provided.
31. Quality Related Costs
These are the costs incurred for ensuring and assuring quality as well as the loss incurred even though the quality is not achieved. Quality related costs are classified as prevention cost, appraisal cost, internal failure cost and external failure cost.
32. Prevention Cost
Prevention cost is the cost incurred to reduce the appraisal cost to a minimum.
33. Appraisal Cost
Appraisal cost is the cost incurred initially for ascertaining conformance of quality of product according to the requirements. For example: Inspection and testing cost.
34. Internal Failure Cost
A cost is arising from inadequate quality discovered before the transfer of ownership from supplier to purchaser.
35. Relevant Costs
CIMA defines relevant costs
costs appropriate to a specific management decision.
36. Social Responsibility Cost
CIMA defines social responsibility cost as
tangible and intangible costs and losses sustained by third parties or the general public as a result of economic activity.
37. Target Cost
CIMA defines target cost as,
a product cost estimate derived from a competitive market price. Used to reduce costs through continuous improvement and replacement of technologies and processor
38. Inventorial Cost
It is the cost incurred for manufacturing a product and considered as assets under generally accepted accounting principles. For example: Research and Development cost. The inventorial cost becomes expenses when the products are sold.
39. Deferred Cost
The Company does not receive an economic benefit of a cost during the accounting period in which the cost is incurred. Such cost is termed as deferred cost. For example: Prepaid Insurance. It is otherwise called as unexpired expenses or unexpired cost and treated as an asset.
It is an expired cost and the company has received its economic benefit. Moreover, the economic benefit is more than the expired cost. For example: Rent paid for the accounting period.
It is also an expired cost and the company has received its economic benefit. But, the received economic benefit is less than the expired cost.
