Cost volume profit (CVP) analysis
• A technique used to determine the effects of
changes in an organisation’s sales volume on its
costs, revenue and profit
• Can be used in profit-seeking organisations and
not-for-profit organisations

The break-even point
• The volume of sales where the total revenues and
costs are equal, and the operation breaks even
• At this level of sales, there is no profit or loss
• Can be calculated for an entire organisation or for
individual projects

Terminology
• Contribution margin (or variable costing)
statement
– An income statement that separates fixed and variable
costs and calculates a contribution margin
• Total contribution margin
– The difference between the total sales revenue and the
total variable costs
– The amount available to cover fixed costs and then
contribute to profits
• Unit contribution margin
– The difference between the sales price per unit and the
variable cost per unit

Terminology (cont.)
• Contribution margin ratio
– The unit contribution margin divided by the unit sales
price
– The proportion of each sales dollar available to cover
fixed costs and earn a profit
• Contribution margin percentage
– The contribution margin ratio multiplied by 100
– The percentage of each sales dollar available to cover
fixed costs and earn a profit

Graphing cost volume profit
relationships
• Shows how costs, revenue and profits change as
sales volume changes
• Five steps
1. Draw the axes of the graph
2. Draw the fixed cost line
3. Draw the total cost line
4. Draw the total revenue line
5. Break-even point—where the total revenue and total
cost lines intersect

Profit volume (PV) graph
• Shows the total amount of profit or loss at different
sales volumes
• The graph intercepts the vertical axis at the
amount equal to the fixed costs
• The break-even point is the point at which the total
profit/loss line crosses the horizontal axis

Target net profit
• A desired profit level determined by management
• The break-even formula can be sued to determine
the target profit

Using CVP analysis for
management decision making
• Safety margin
– Difference between the budgeted sales revenue and
break-even sales revenue
– Gives a feel for how close projected operations are to the
break-even point
• Changes in fixed costs
– Percentage change in fixed costs will lead to a similar
increase in the break-even point (in units or dollars)
– Different fixed costs may apply to different levels of
sales/production volume, and provide more than one
break-even point

Using CVP analysis for
management decision making
(cont.)
• Changes in the unit contribution margin
– Change in unit variable costs, leads to new
– unit contribution margin and new break-even point
– An increase in unit variable costs will increase the break-
even point
– An increase in unit price will lower the break-even point

Multiple changes in key variables
• May involve, for example
– Increasing unit prices
– Increasing selling prices
– Undertaking a new advertising campaign
– Leasing a new office
• An incremental approach to analysis
– Focuses on the differences in the total contribution
margin, fixed costs and profits under the two alternatives

CVP analysis with multiple
products
• Sales mix
– The relative proportions of each type of product sold by
the organisation
• Weighted average unit contribution margin
– The average of the products’ unit contribution margins,
weighted by the sales mix

Assumptions underlying CVP
analysis
• The behaviour of total revenue is linear
• The behaviour of total costs is linear over a
relevant range
– Costs can be categorised as fixed, variable or
semivariable
– Labour productivity, production technology and market
conditions do not change
– There are no capacity changes during the period under
consideration

Assumptions underlying CVP
analysis (cont.)
• For both variable and fixed costs, sales volume is
the only cost driver
• The sales mix remains constant over the relevant
range
• In manufacturing firms, the levels of inventory at
the beginning and end of the period are the same
– Thus, the number of units produced and sold during a
period are equal

CVP analysis and longer-term
decisions
• CVP analysis is usually regarded as a short-term
or tactical decision tool
• Classification of costs as variable or fixed is
usually based on cost behaviour over the short
term
• The financial impact of long-term decisions is best
analysed using capital budgeting techniques
– Takes into account the time value of money

Treating CVP analysis with
caution
• CVP analysis is merely a simplified model
• The usefulness of CVP analysis may be greater in
less complex smaller firms, or stand-alone
projects
• For larger firms, CVP analysis can be valuable as
a decision tool for the planning stages of new
projects and ventures

An activity-based approach to CVP
analysis
• ABC categorises activities as unit, batch, product
or facility level
– Facility, product and batch activities are non-volume
activity costs

Limiting assumptions of CVP
analysis using activity-based
costs
• Total batch level costs are dependent on the
batch size and the break-even/target production
level
• Management may change the batch size at
certain production volume levels and this will
change the break-even volume
• More complex models are needed where there
are multiple products

Financial planning models
• Sensitivity analysis and CVP analysis
– An approach that examines how an outcome may change if
there are variations in the predicted data or underlying
assumptions
• Can be run using spreadsheet software, such as Excel
• Goal seek approaches
– The analyst specifies the outcome, and the software specifies
the necessary inputs
• What-if analysis
– The analyst specifies changes in assumptions and data to
examine the effect of these changes on the outputs

Summary• CVP analysis is a decision tool that can be used to
assess the effects on changes in profit of changes in
sales volume, sales price, sales mix and costs
• The break-even point is the sales level at which sales
covers costs—there are zero profits
• The break-even formula can be modified to calculate
target profit, and to include sales mix and income
taxes
• CVP analysis has several assumptions which limit its
usefulness for decision making
• Activity-based approaches and financial planning
modelling can provide more sophisticated models
