Nature and scope of cost accounting?

nature and scope, cost concepts, installation of cost, functions and importance of cost accounting?

Cost accounting is the process of tracking, recording and analyzing costs associated with the products or activities of an organization. Cost accounting need not follow generally accepted accounting principles, or GAAP, because its primary use is for internal managers, rather than external auditors. Costs are measured in units of currency by convention. Cost accounting could also be defined as a kind of management accounting that translates the Supply Chain (the series of events in the production process that, in concert, result in a product) into financial values. Managers use cost accounting to support decision making to reduce a company's costs and improve its profitability.

There are at least four approaches:

* Standardized Cost Accounting
* Activity-based Costing
* Throughput Accounting
* Marginal Costing

Cost Elements:

* 1) Raw Material
* 2) Manual Labor
* 3) Indirect Expenses

Activity-based costing

Activity-based costing (ABC) is a system for assigning costs to products based on the activities they require. In this case, activities are those regular actions performed inside a company. "Talking with customer regarding invoice questions" is an example of an activity performed inside most companies.

Accountants assign 100% of each employee's time to the different activities performed inside a company (many will use surveys to have the workers themselves assign their time to the different activities). The accountant then can determine the total cost spent on each activity by summing up the percentage of each worker's salary spent on that activity.

A company can use the resulting activity cost data to determine where to focus their operational improvement efforts. For example, a job based manufacturer may find that a high percentage of their workers are spending their time trying to figure out a hastily written customer order. Via ABC, the accountants now have a currency amount that will be associated with the activity of "Researching Customer Work Order Specifications". Senior management can now decide how much focus or money to budget for the resolutions of this process deficiency. Activity-based management includes (but is not restricted to) the use of activity-based costing to manage a business.

Marginal Costing

This method is used particularly for short-term decision-making. Its principal tenets are:

* Revenue (per product) - Variable Costs (per product) = Contribution (per product)
* Total Contribution - Total Fixed Costs = Total Profit or (Total Loss)

Thus it does not attempt to allocate fixed costs in an arbitrary manner to different products. The short-term objective is to maximize contribution per unit. If constraints exist on resources, then Managerial Accounting dictates that marginal cost analysis be employed to maximize contribution per unit of the constrained resource (see Development of Throughput Accounting, above).

various types of costs are :

Fixed costs
variable costs
Marginal costs
incremental costs
opportunity costs
sunken costs

To explain all these it takes a lot...as each one of them is a concept itself..
u should have asked each one of them in different question...to get accurate answers...
any ways..i hope this info is useful to u...
Good luck..!!!!

brutal internal accounting you never want to do
