Difference in Income Absorption Vs. Variable
• No change in inventory level– Absorption Income = Variable Income
• Increase in inventory level– Absorption Income > Variable Income– Phantom Profits
• Decrease in inventory level– Absorption Income < Variable Income
Cost-Volume-Profit Analysis
• Relationship of– Revenue– Costs– Volume changes– Taxes– Profits
• Applies to– Manufacturers– Wholesalers– Retailers– Service Industries
Cost-Volume-Profit Analysis
• Compute the break-even point
• Calculate the level of sales necessary to achieve a target profit
• Set sales price
• Answer “what-if” questions
Cost-Volume-Profit Assumptions
• Company is operating within the relevant range
• Revenue per unit remains constant
• Variable costs per unit remain constant
• Total fixed costs remain constant
• Mixed costs are separated into variable and fixed elements
Equations
• Break-even point
Total Revenues = Total CostsTotal Revenues - Total Costs = Zero Profit
• Contribution Margin (CM)Sales Price - Variable Cost = CM per unit
Revenue - Total Variable Costs = CM in total
Break-Even Formula - Units
Total Fixed Costs
Sales Price (per unit) - Variable Cost (per unit)
$100,000 12 - 4 = 12,500 units
If fixed costs are $100,000, unit sales price is $12, and unit variable cost is $4, the break-even point is 12,500 units

Break-Even Formula - DollarsTotal Fixed Costs
Sales Price (per unit) - Variable Cost (per unit)
Sales Price (per unit)
If fixed costs are $100,000, unit sales price is $12, and unit variable cost is $4, the break-even point is $150,000
$100,000 12 - 4 = $150,000 12

If fixed costs are $100,000, unit sales price is $12, and unit variable cost is $4, the break-even point is 12,500 units
Using Cost-Volume-Profit Analysis
• Setting a target profit– Enter before-tax profit in numerator
$100,000 + $30,000 12 - 4 = $195,000 12
If fixed costs are $100,000, unit sales price is $12, unit variable cost is $4, and the desired before-tax profit is $30,000, the required sales are $195,000
Using Cost-Volume-Profit Analysis• Setting a target profit
– Convert after-tax profit to before-tax profit
Before-tax profit = After-tax profit
1 - tax rate
$36,000 = 1 - 40%$60,000
At a 40% tax rate, an after-tax profit of $36,000 equals a before-tax profit of $60,000
• Setting a target profit– Convert after-tax profit to before-tax profit – Enter before-tax profit in numerator
If fixed costs are $100,000, unit sales price is $12, unit variable cost is $4, and the desired after-tax profit is $36,000, the required sales are $240,000
$100,000 + $60,000 12 - 4 = $240,000 12

Incremental Analysis
• Changes in revenues, costs, and/or volume
• Break-even point increases when– fixed costs increase– sales price decreases– variable costs increases
Multiproduct Cost-Volume-Profit Analysis
• Assumes a constant product sales mix
• Contribution margin is weighted on the quantities of each product included in the “bag” of products
• Contribution margin of the product making up the largest proportion of the bag has the greatest impact on the average contribution margin of the product mix

Margin of Safety
• Budgeted (or actual) sales after the break-even point
• Indication of risk
Margin of Safety
• Units
Actual units - break-even units• Dollars
Actual sales dollars - break-even sales dollars• Percentage
Margin of Safety in units or dollarsBreak-even units or sales in dollars
Operating Leverage
• Relationship of variable and fixed costs
• Effect on profits when volume changes
• Cost structure strongly influences the impact changes in volume have on profits
Operating Leverage
High Operating Leverage• Low variable costs• High fixed costs• High contribution margin • High break-even point• Sales after break-even
have greater impact on profits
Low Operating Leverage• High variable costs• Low fixed costs• Low contribution margin• Low break-even point• Sales after break-even
have lesser impact on profits
Degree of Operating Leverage
• Measures how a percentage change in sales will affect profits
• Degree of Operating Leverage
Contribution Margin
Profit Before Taxes
• When margin of safety is small, the degree of operating leverage is large
Cost-Volume-Profit Assumptions• Company is operating within the relevant range
• Revenue and variable cost per unit are constant
• Total contribution margin increases proportionally with increases in unit sales
• Total fixed costs remain constant
• Mixed costs are separated into variable and fixed elements
Cost-Volume-Profit Assumptions
• No change in inventory (production equals sales)
• No change in capacity
• Sales mix remains constant
• Anticipated price level changes included in formulas
• Labor productivity, production technology, and market conditions remain constant
Additional Considerations
• Are they fixed costs or long-term variable costs?
• Quality improvements may violate assumptions– increase costs during implementation– increase productivity– decrease costs– adjust sales price
