4、 is incurred even when the facility is unused,and a variable portion that increases withusage.Utilities typically behave in this manner.Fixed MonthlyUtility ChargeVariable Cost per KWActivity(Kilowatt Hours)Total Utility CostTotal mixed cost C 121-6Step-Wise CostsTotal cost increases to a new higher

5、 cost for the next higher range of activity,but remains constant within a range of activity.C 121-7Curvilinear Costs Costs that increase when activityincreases,but in a nonlinear manner.C 121-8 Measuring Cost BehaviorThe objective is to classify all costs as either fixed or variable.We will look at

6、three methods:1.Scatter diagrams.2.The high-low method.3.Leastsquares regression.A scatter diagram is a plot of cost data points on a graph.It is almost always helpful to plot cost data to be able to observe a visual picture of the relationship between cost and activity.P 121-90 1 2 3 4 5 6*Total Co

10、and the variable unit cost.Least-Squares RegressionLeast-squares regression is usually covered in advanced cost accounting courses.It is commonly used with spreadsheet programs or calculators.P 121-14Using Break-Even AnalysisThe break-even point(expressed in units of product or dollars of sales)is t
