Cost accounting- A Brief Look

From Wikipedia, the free encyclopedia


In management accounting, cost accounting establishes budget and actual cost of operations, processes, departments or product and the analysis of variances, profitability or social use of funds. Managers use cost accounting to support decision-making to cut a company's costs and improve profitability. As a form of management accounting, cost accounting need not follow standards such as GAAP, because its primary use is for internal managers, rather than outside users, and what to compute is instead decided pragmatically.

Costs are measured in units of nominal currency by convention. Cost accounting can be viewed as translating the Supply Chain (the series of events in the production process that, in concert, result in a product) into financial values.

There are various managerial accounting approaches:

* Standardized or Standard Cost Accounting
* Lean accounting
* Activity-based Costing
* Resource Consumption Accounting
* Throughput Accounting
* Marginal Costing / Cost-Volume-Profit Analysis


Classical Cost Elements are:

1. Raw Materials
2. Labor
3. Indirect Expenses / Overhead

Cost accounting has long been used to help managers understand the costs of running a business. Modern cost accounting originated during the industrial revolution, when the complexities of running a large scale business led to the development of systems for recording and tracking costs to help business owners and managers make decisions.

In the early industrial age, most of the costs incurred by a business were what modern accountants call "variable costs" because they varied directly with the amount of production. Money was spent on labor, raw materials, power to run a factory, etc. in direct proportion to production. Managers could simply total the variable costs for a product and use this as a rough guide for decision-making processes.

Some costs tend to remain the same even during busy periods, unlike variable costs which rise and fall with volume of work. Over time, the importance of these "fixed costs" has become more important to managers. Examples of fixed costs include the depreciation of plant and equipment, and the cost of departments such as maintenance, tooling, production control, purchasing, quality control, storage and handling, plant supervision and engineering. In the early twentieth century, these costs were of little importance to most businesses. However, in the twenty-first century, these costs are often more important than the variable cost of a product, and allocating them to a broad range of products can lead to bad decision making. Managers must understand fixed costs in order to make decisions about products and pricing.

For example: A company produced railway coaches and had only one product. To make each coach, the company needed to purchase $60 of raw materials and components, and pay 6 laborers $40 each. Therefore, total variable cost for each coach was $300. Knowing that making a coach required spending $300, managers knew they couldn't sell below that price without losing money on each coach. Any price above $300 became a contribution to the fixed costs of the company. If the fixed costs were, say, $1000 per month for rent, insurance and owner's salary, the company could therefore sell 5 coaches per month for a total of $3000 (priced at $600 each), or 10 coaches for a total of $4500 (priced at $450 each), and make a profit of $500 in both cases.
[edit] Elements of Cost

* 1. Material
o A. Direct Material
o B. indirect Material
* 2. Labour
o A. Direct Labour
o B. Indirect Labour
* 3. Expenses
o A. Direct Expenses
o B. Indirect Expenses

All (B) elements are together called Overheads. They are grouped further based on their functions as,

* 1. Production or Works Overheads
* 2. Administration Overheads
* 3. Selling overheads
* 4. Distribution Overheads

Classification of Costs

Classification of cost means, the grouping of costs according to their common characteristics. The important ways of classification of costs are :

* (1) By nature or element: materials, labour, expenses
* (2) By functions: production, selling, distribution, administration, R&D, development,
* (3) As direct and indirect
* (4) By variability : fixed, variable, semi-variable
* (5) By controllability : controllable, uncontrollable
* (6) By normality : normal, abnormal

Standard Cost Accounting

In modern cost accounting, the concept of recording historical costs was taken further, by allocating the company's fixed costs over a given period of time to the items produced during that period, and recording the result as the total cost of production. This allowed the full cost of products that were not sold in the period they were produced to be recorded in inventory using a variety of complex accounting methods, which was consistent with the principles of GAAP (Generally Accepted Accounting Principles). It also essentially enabled managers to ignore the fixed costs, and look at the results of each period in relation to the "standard cost" for any given product.

For example: if the railway coach company normally produced 40 coaches per month, and the fixed costs were still $1000/month, then each coach could be said to incur an overhead of $25 ($1000/40). Adding this to the variable costs of $300 per coach produced a full cost of $325 per coach.

This method tended to slightly distort the resulting unit cost, but in mass-production industries that made one product line, and where the fixed costs were relatively low, the distortion was very minor.

For example: if the railway coach company made 100 coaches one month, then the unit cost would become $310 per coach ($300 + ($1000/100)). If the next month the company made 50 coaches, then the unit cost = $320 per coach ($300 + ($1000/50)), a relatively minor difference.

An important part of standard cost accounting is a variance analysis which breaks down the variation between actual cost and standard costs into various components (volume variation, material cost variation, labor cost variation, etc.) so managers can understand why costs were different from what was planned and take appropriate action to correct the situation.
