Cost Behavior
• 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.

Relevant Range
• 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.
![Page 6: CHAPTER 18 Cost Behavior & Cost-Volume-Profit Analysis](https://reader035.vdocuments.net/reader035/viewer/2022081506/56649eff5503460f94c13fac/html5/thumbnails/6.jpg)
Cost Behavior
• __________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.

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
![Page 23: CHAPTER 18 Cost Behavior & Cost-Volume-Profit Analysis](https://reader035.vdocuments.net/reader035/viewer/2022081506/56649eff5503460f94c13fac/html5/thumbnails/23.jpg)
Related Questions
• 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?

Breakeven Sales• 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)

Breakeven for Multiple Products
• 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.

Breakeven for Multiple Products - Example
• 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
