6. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-6 Operating Leverage A measure of the extent to which fixed costs are being used in an organization. Operating leverage is greatest in companies that have a high proportion of fixed costs in relation to variable costs. A measure of the extent to which fixed costs are being used in an organization. Operating leverage is greatest in companies that have a high proportion of fixed costs in relation to variable costs. Consider the following concert example where all costs are fixed. Fixed Costs Small percentage change in revenue Large percentage change in profits

7. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-7 Operating Leverage When all costs are fixed, every additional sales dollar contributes one dollar to gross profit. 10% Revenue Increase 90% Gross Profit Increase

8. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-8 Risk and Reward Assessment Risk refers to the possibility that sacrifices may exceed benefits. Risk may be reduced by converting fixed costs into variable costs. Let’s see what happens to the concert example if the band receives $16 per ticket sold instead of a fixed $48,000.

42. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-42 Context Sensitive Definitions of Fixed and Variable Recall the earlier concert example, where the band was paid $48,000 regardless of the number of tickets sold. The cost of the band is fixed relative to the number of tickets sold for a specific concert. The cost of the band is variable relative to the number of concerts produced.

Cost Averaging

45. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-45 Cost Averaging Average costs decline as activity increases when fixed costs such as equipment rental are involved. Managers must use these average costs with caution as they differ at every level of activity.

61. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-61 Regression Method of Cost Estimation A method used to analyze mixed costs if a scattergraph plot reveals an approximately linear relationship between the X and Y variables. This method uses all of the data points to estimate the fixed and variable cost components of a mixed cost. The goal of this method is to fit a straight line to the data that minimizes the sum of the squared errors.

62. The McGraw-Hill Companies, Inc. 2008McGraw-Hill/Irwin 2-62 Regression Method of Cost Estimation Software can be used to fit a regression line through the data points. The cost analysis objective is the same: Y = a + bX Least-squares regression also provides a statistic, called the R 2, that is a measure of the goodness of fit of the regression line to the data points.
