If a particular cost “goes away” when a product is dropped from the product line, the cost is direct. Types of Costs bc BOS Copyright169。 Company, Inc. Cost Accounting 13 Cost Accounting ?All costs are variable over a very long time horizon (., for very large increases in volume) – Costs to run and maintain a puter system that tracks product orders are clearly fixed for a small change in volume, such as that associated with a slightly busy month. However, they are variable for a large change in volume, such as that associated with a new plant. ?Most costs are semivariable (., they tend to be added in lumps as volume increases) – Supervisory labor tends to be considered fixed because it is unlikely that additional supervisors would have to be added to handle a small increase, say 10%, in volume. But the workforce can only increase so much before an additional supervisor is needed. – In theory, production labor is variable. However, in many client situations, restraints placed by unions and difficulty in hiring and firing people in response to shortterm volume fluctuations make it, in practice, semivariable. Defining the appropriate time horizon for the analysis is important. A meaningful analysis will isolate the fixed cost and variable ponents of a particular cost Fixed vs. Variable bc BOS Copyright169。 Company, Inc.
