Calculating the 'Target Profit' shows the
amount of output that needs to be sold in
order to give a certain amount of profit
(fixed costs + target profit) / Contribution per unit
Contribution sales/Profit Volume ratio
Expresses the amount of contribution in relation to the amount of the selling price
Formula
Contribution / Selling Price
Calculated on the basis of a single unit of production or for the whole business
If Fixed costs are known, we can use the CS ratio to find the sales value at which
the business breaks-even, or the sales value to give a target amount of profit
Dis-advantages/ Limitations
Based on estimates
No semi-variables
External factors not considered, such as
economy, interest rates, the rate of inflation, etc
Relationship between sales revenue, variable costs and
fixed costs remains the same at all levels of production.
Only useful if the product is going sell in sufficient
quantities
Difficult to make calculations for a mix of products, therefore it
require separate calculations for every different type of product
costs and revenue are expressed in terms of straight lines,
however the relationship is not always so. Selling prices vary at
different quantities sold; in similar way, variable costs alter at
different levels as advantage is taken of the lower prices to be
gained from bulk buying, and/or more efficient production methods
Fixed costs do not remain fixed at all levels of
output
You can not forecast from the graph of what could
be obtained by selling more units, therefore not
allowing you to extrapolate the graph or
calculations
The profit or loss shown by the graph or calculations is
probably only true for figures close to current output levels -
the more that output changes from the current figures, the
less accurate will be the expected profit or loss
Advantages
Useful for a new business in order establish the level of sales that must be
achieved to reach break-even point.
When to use Break-even analysis?
Before starting a new business
The calculation of break-even point is important in
order to see the level of sales needed by the
business in order to cover costs, or to make
particular levels of profit. The feasibility of achieving the
level can be considered by the owner of the business,
and other parties such as the bank manager.
When making changes within a business
The cost of a major change will need to be
considered by the owners and/or managers.
Eg. a large increase in production will. most
likely, affect the balance between fixed and
variable costs. Break-even analysis will be
used as part of the planning process to
ensure that the business remains profitable.
To measure profits and losses
Within the limitations of break-even analysis, profits and
losses can be estimated at different levels of output from
current production. (Remember that this can be done
only where the new output is close to current levels and
where there is no major change to the structure of costs
- ie. it is not possible to extrapolate)
To answer 'what if?' questions
Questions such as 'what if sales fall by 10%?' and 'what if fixed costs increase
by £1,000?' can be answered - in part at least - by break-even analysis. The
effect on the profitability of the business can be seen, subject to the limitations.
A question such as 'what if sales increase by 300 per cent?' is a fundamental
change that it can only be answered by exclaiming the effect on the nature of
the fixed and variable costs and then re-calculating the break-even point.
To evaluate alternative viewpoints
There are often different ways of production; this is particularly true of a
manufacturing business. For example, a product could be made, either by a
labour-intense process, with a large number of employees supported by basic
machinery, or buy using expensive machinery in an automated process with
very few employees. In the first case, the cost structure will be high variable
costs (labour) and low fixed costs (depreciation of machinery). In the second,
there will be low variable costs and high fixed costs. Break-even analysis can
be used to examine the relationship between the costs which are likely to show
a low break-even point in the first case, and a high break-even point in the
second. In this way, the management of the business is a guided by
break-even analysis; management will also need to know the likely sales
figures, and the availability of money with which to buy the machinery.
