There are a variety of reasons why Tracy Corporation classifies costs as fixed or variable components. These reasons include price fixing, decreasing costs, profit planning, cost-benefit analysis, cost-volume-profit analysis and budgeting. Tracy Corporation may also use different methods to classify cost behaviour, namely managerial judgment, engineering approach, quantitative analysis (such as the high-low method), visual fit and regression analysis. (The sources mentioned could also be consulted for the advantages and disadvantages of each method.)
