CHAPTER 4 Cost-Volume-Profit Analysis

Purpose of Budgeting Planning Control Decision making
How many units of input do I need to support a budgeted output? Control Are operations effective and efficient? Decision making How do we decide on a price, and choose quantity given constraints? Learning objective 1: Identify common cost behavior patterns

Common Cost Behavior Patterns
Variable Costs Costs which change directly in proportion to changes in quantity or activity Fixed Costs Costs which do not change when quantity or activity volume changes Learning objective 1: Identify common cost behavior patterns

Common Cost Behavior Patterns
Mixed Costs Costs that have both variable and fixed elements Step Costs Fixed for a range of output, but increase when upper bound of range is exceeded Learning objective 1: Identify common cost behavior patterns

Variable Costs Costs that change in proportion to changes in volume or activity An automobile manufacturer will need 400 tires to make 100 cars, but 4,000 tires to make 1,000 cars A bakery will need 2 eggs to make 1 cake and 20 eggs to make 10 cakes If activity increases by 10%, cost increases by 10% Learning objective 1: Identify common cost behavior patterns

Variable Costs A company has decided that direct labor costs are 100% variable. Last month total direct labor costs were \$125,000 and total direct labor hours worked were 10,000. What is the direct labor cost per hour? \$125,000 / 10,000 hours = \$12.50 per hour Predict labor costs in a month when 12,000 labor hours are worked \$12.50 per hour × 12,000 hours = \$150,000 Learning objective 1: Identify common cost behavior patterns

Variable Costs Total Variable Cost = \$91 × Units produced
Learning objective 1: Identify common cost behavior patterns

Fixed Costs Do not change in response to changes in activity level
Typical fixed costs are depreciation, supervisory salaries, and building maintenance Rent for a bakery will not double if output increases from 100 to 200 cakes Activity increases by 10%, costs remain unchanged Learning objective 1: Identify common cost behavior patterns

Fixed Costs Total fixed cost = \$94,000
Learning objective 1: Identify common cost behavior patterns

Fixed Costs Discretionary Fixed Costs Committed Fixed Costs
Management can easily change Advertising, research and development Many companies cut back on these costs when sales drop. This can be shortsighted. Why? Committed Fixed Costs Cannot be easily changed Rent, insurance Learning objective 1: Identify common cost behavior patterns

Using Less Water but Paying Higher Rates!
Fixed Costs LINK TO PRACTICE Using Less Water but Paying Higher Rates! What happens to cost per unit when fixed costs remain the same but volume or activity declines? Can you think of another way to set rates to make ratepayers less angry? Learning objective 1: Identify common cost behavior patterns

Mixed Costs Contain both variable and fixed cost elements
Can separate mixed costs into variable and fixed components Salesperson with base salary (fixed) and commission on sales (variable) Base salary included with fixed costs Commission included with variable costs Learning objective 1: Identify common cost behavior patterns

Mixed Costs Total cost = (\$91 × Units produced) + \$94,000
Learning objective 1: Identify common cost behavior patterns

Step Costs Fixed cost for a specific range
Increases to higher level when upper bound of range is exceeded Use correct cost when budgeting for a particular relevant range Company adds third production shift, cost increase includes supervisory salary Learning objective 1: Identify common cost behavior patterns

Step Costs Total step costs =
\$94,000 for relevant range 0 – 3,000 units produced \$144,000 for relevant range 3,001 – 6,000 units \$194,000 for relevant range 6,001 – 9,000 units Learning objective 1: Identify common cost behavior patterns

Direct Labor Q Is direct labor always a variable cost?
Are you willing to lay off workers when production declines? What if the decline is temporary? What if the decline is permanent? Does the degree of automation make a difference in whether direct labor is fixed or variable? Learning objective 1: Identify common cost behavior patterns

Cost Estimation Methods
Account Analysis -Classify costs into variable and fixed pools Scattergraphs -Can see cost relationships visually High-Low Method -Linear estimation connects high and low volume observations Regression Analysis -Linear estimation is best fit to observed values Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Account Analysis Most common approach
Requires professional judgment of management Management classifies costs as fixed, variable, or mixed Total variable costs divided by activity equals variable cost per unit Variable cost per unit and total fixed costs can be used in cost equation Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Account Analysis Total cost = (\$81.50 Variable cost per unit × Units produced) + \$102,000 Fixed costs Expected cost of 2,500 units = (\$81.50 × 2,500) + \$102,000 = \$305,750 Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Account Analysis Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Scattergraphs Utilization of cost information from previous periods
Weekly, monthly, or quarterly cost reports Plot the actual costs at the observed activity levels Look for relationship between cost and activity, linear is ideal Use relationship to predict future costs Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Scattergraphs Is there a relationship between units produced and production costs? Describe the relationship. Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

High-Low Method Utilization of cost information from previous periods
Connect straight line from lowest activity level to highest activity level Slope of the line (change in cost divided by change in activity) equals variable cost per unit Total cost at lowest or highest activity level minus variable cost at that level equals fixed cost Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

High-Low Method Total cost at high activity level
Total cost at low activity level Learning objective 2: Estimate the relation between cost and activity using account analysis and the high-low method

Assumptions in CVP Analysis
Assumptions can affect the validity of the analysis Costs can be separated into fixed and variable components Total fixed cost and unit variable cost do not change over the levels of interest Multiproduct analysis assumes the product mix does not change Despite assumptions, CVP is useful Learning objective 4: Perform cost-volume profit analysis for multiple products

Operating Leverage Level of fixed versus variable costs in a company
High level of fixed costs has a high operating leverage - Companies with high operating leverage have large fluctuations in profit when sales increase or decrease Learning objective 5: Discuss the effect of operating leverage

Fixed vs. Variable Costs
LINK TO PRACTICE Fixed Costs Too High—Make Them Variable! Can you think of any ways other than incentive compensation and outsourcing to turn fixed costs into variable costs? Would you rather have fixed or variable costs when revenues are increasing? When revenues are decreasing? Learning objective 5: Discuss the effect of operating leverage

Constraints Constraints on how many items can be produced
Shortage of space, equipment, or labor Utilize contribution margin per unit to analyze situations - Calculate contribution margin per unit of constraint Produce product with highest contribution margin per unit of constraint Linear programming can solve multiple constraints Learning objective 6: Use the cost per unit of the constraint to analyze situations involving a resource constraint
