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 and not-for
profit organisations

The break-even point
 The volume of sales where the total
revenues and expenses are equal, and the
operation breaks even
 Can be calculated for an entire organisation
or individual projects or activities

Changes in fixed expenses
 When estimates of fixed costs are revised,
the break-even point will change

similar increase in the break-even point (in units
or dollars)

levels of sales/production volume
More than one break-even point

contribution margin, fixed expenses and profits
under the two alternatives

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

21
Assumptions underlying
CVP analysis
 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, levels of inventory
at the beginning and end of the period are
the same

CVP analysis and longterm decisions
 CVP analysis is usually regarded a shortterm 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
best analysed using capital budgeting
techniques

23
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

24
An activity-based
approach to CVP analysis
 ABC categorises activities as facility,
product, batch or unit costs
Facility, product and batch activities are nonvolume activity costs
Break - even point =
Total batch, product and facility level costs
Sellingprice per unit - costs per unit

25
Limiting assumption of
using activity-based costs
 Batch costs are based on likely production
levels
 New planned production levels lead to
changes in the number of production
batches, and changes in total non-volume
activity costs -> new break-even or target
profit volume

Sensitivity analysis and
CVP analysis
 Sensitivity analysis
An approach which examines how an outcome
may change due to variations in the predicted
data or underlying assumptions
 Can be run using spreadsheet software,
such as Excel

Sensitivity analysis and
CVP analysis
 Goal seeking approaches
Allows the analyst to specify the outcome, so
that software can specify the necessary inputs
 What-if analysis
The analyst specifies changes in assumptions to
examine the effect of these changes on the
output
