Measuring Costs

Measuring profits or net income is the most important thing accountants do. The second most important task is measuring costs. Costs are extremely important to running a business and managing them effectively can make a substantial difference in a company's bottom line.

Any business that sells products needs to know its product costs and depending on what is being manufactured and/or sold, it can get complicated. Every step in the production process has to be tracked carefully from start to finish. Many manufacturing costs cannot be directly matched with particular products; these are called indirect costs. To calculate the full cost of each product manufactured, accountants devise methods for allocating indirect production costs to specific products. Generally accepted accounting principles (GAAP) provide few guidelines for measuring product cost.

Accountants need to determine many other costs, in addition to product costs, such as the costs of the departments and other organizational units of the business; the cost of the retirement plan for the company's employees; the cost of marketing and advertising; the cost of restructuring the business or the cost of a major recall of products sold by the company, should that ever become necessary.

Cost accounting serves two broad purposes: measuring profit and furnishing relevant information to managers. What makes it confusing is that there's no one set method for measuring and reporting costs, although accuracy is paramount. Cost accounting can fall anywhere on a continuum between conservative or expansive. The phrase actual cost depends entirely on the particular methods used to measure cost. These can often be as subjective and nebulous as some systems for judging sports. Again accuracy is extremely important. The total cost of goods or products sold is the first and usually largest expense deducted from sales revenue in measuring profit.

Types of Costs

Direct costs are those costs that cann be directly attributed to a product or product line, or to one source of sales revenue, or one business unit or operation of the business. An example of a direct cost would be the cost of tires on a new automobile.

Indirect costs are very different and can't be attached to any specific product, unit or activity. The cost of labor or benefits for an auto manufacturer is certainly a cost, but it can't be attached to any one vehicle. Each business has to devise a method of allocating indirect costs to different products, sources of sales revenue, business units, etc. Most allocation methods are less than perfect, and generally end up being arbitrary to one degree or another. Business managers and accounts should always keep an eye on the allocation methods used for indirect costs and take the cost figures produced by these methods with a grain of salt.

Fixed costs are those costs that stay the same over a relatively broad range of sales volume or production output. They're like an albatross around the neck of business and a company must sell its product at a high enough profit to at least break even.

Variable costs can increase and decrease in proportion to changes in sales or production level. Variable costs vary proportionately with changes in production/

Relevant costs are essentially future costs that could be incurred, depending on what strategic course a business takes. If an auto manufacturer decides to increase production, but the cost of tires goes up, than that cost needs to be taken into consideration.

Irrelevant costs are those that should be disregarded when deciding on a future course of action. They're costs that could cause you to make a wrong decision. Whereas relevant costs are future costs, irrelevant costs are those costs that were incurred in the past. The money's gone.
