### CHAPTER 18

Cost Behavior & Cost-Volume-Profit Analysis

• In planning, we must understand how costs behave.

• For example, do costs change as production activity changes or do they stay the same?

• __________– costs that increase as production activity increases (direct materials, direct labor)

• __________– costs that stay the same over a range of activity levels (depreciation, rent) within a given time period.

• Cost relationships remain stable only over some range of production activity.

• Outside that range the relationships may change.

• __________is the expected range of activity we are interested in.

• We estimate the cost relationships within that range.

• We cannot extrapolate outside the range.

• __________Costs

• include both fixed and variable costs; we separate fixed from variable costs when perform cost-volume profit analysis.

• __________Costs

• fixed within a relevant range, but if total production increases significantly, total costs increase by a lump sum amount

• __________Costs

• increase at a non-constant rate as volume increases.

• Some costs have a _______component and a __________component.

• We can separate mixed costs into the two components using the ________________.

Vertical distance is the change in cost.

Horizontal distance is the change in activity.

Measuring Cost BehaviorHigh/Low Method

• Determine the __________by finding the slope

• change in ____÷ change in _____

• (see prev. slide)

• Determine the __________component

• Using the high (or the low) point, plug in the cost (y), the activity (x), and the slope (VC/unit).

• Solve for the y- intercept.

• Given the equation of the cost line, we can now use it to predict cost over some range of activity.

Cost-Volume-Profit & Breakeven Analysis

• Given our fixed and variable costs, we can use CVP techniques to help predict our profit at various activity levels.

• We define

• __________= Sales – VC

• __________= SP/unit – VC/unit

• __________= CM/SP

• We can use this set of techniques to answer the following types of questions.

• How many units do we need to sell to break even?

• How much profit will we generate at a given level of sales?

• If we want to earn a target profit, how many units do we need to sell?

• If we change our sales price, what happens to our profitability?

Contribution margin is amount by which revenue exceeds the variable costsof producing the revenue.

P2

How much contribution margin must this company have to cover its fixed costs (break even)?

P2

How many units must this company sell to cover its fixed costs (i.e. to break even)?

Answer: \$24,000 ÷ \$30 per unit = 800 units

• Sales = VC + FC + profit or

• Profit = Sales – VC – FC

• At breakeven, profit = 0

• 0 = (Sales – VC) – FC

• 0 = CM - FC

• CM = FC or

• (CM/unit)(units) = FC

• And Breakeven Units = FC/(CM/unit)

• Or Breakeven in \$ = FC/(CM ratio)

• You can use the CVP idea to determine how much we can sell to earn a desired profit.

• Profit = Sales – VC – FC

• Profit + FC = Sales – VC = CM = CM/unit(units)

• Target Salesunits= (FC + Profit) / CM/unit

• Target Sales\$ = (FC + Profit) / CM ratio

__________is the amount by which sales can drop before the company incurs a loss.

Margin of safety may be expressed as a percentage of expected sales.

• BEunits= FC/(CMcomposite), where

• CMcomposite = [(%A)CMA+ (%B) CMB]

• The number of units that we get will be a combined unit of A and B together.

• You then have to determine the number of A and B each that are actually sold.

• If FC = \$100,000 and CM(a) = \$40 and CM(b) = \$20, and we sell 3 times as many units of B as A, what is the BE point?

• BEunits= 100,000/[(0.25)(\$40) + (0.75)(\$20)]

= 4,000 units

• A = (0.25)(4,000) or 1,000 units of A

• B = (0.75)(4,000) or 3,000 units of B

Contribution margin

Net income

Degree of ____________________=

A measure of the extent to which fixed costs are being used in an organization.

A measure of how a percentage change in sales will affect profits.

• We can recast the income statement to highlight the contribution margin.

• Sales

• - VC

• = CM

• - FC

• = operating income
