Marketers will want to estimate three aspects of current market demand- total market demand, area market demand and actual sales & market shares.
The total market demand for a product or service is
the total volume that would be bought by a defined consumer group in a defined
geographic area in a defined time period in a defined marketing environment
under a defined level and mix of industry marketing effort.
Total market demand is not a fixed number, but a
function of the stated conditions. It will also depend on many environmental
factors, ranging from the level of consumer health concerns to the weather in
key market areas.
Companies have developed various practical methods for
estimating total market demand. We will illustrate two here. Suppose Warner
Communications Company wants to estimate the total annual sales of recorded
compact discs. A common way to estimate total market demand is as follows:
Q=n
x q x p
Where
Q = Total Market Demand
n= Number of buyers in the market
q = quantity purchased by an average buyer per year.
p = price of an average unit.
Thus,
if there are 100 million buyers of compact discs each year, the average buyer
buys six discs a year, and the average price is $17, then the total market
demand
for discs is $10.2 billion = (100 000 000
x 6 x $17).
A
variation of this approach is the chain ratio method. This method involves
multiplying a base number by a chain of adjusting percentages. This simple
chain of calculations would provide only a rough estimate of potential demand. However, more detailed chains
involving additional segments and other qualifying factors would yield more
accurate and refined estimates.
ESTIMATING AREA MARKET DEMAND
Companies
face the problem of selecting the best sales territories and allocating their
marketing budget optimally among these territories. Therefore, they need to
estimate the market potential of different cities, provinces, and countries.
Two major methods are available: 1) Market-buildup method, which is used
primarily by business goods firms, and 2) Market-factor index method, which is used
primarily by consumer goods firms.
Market-Factor Index Method
Consumer
goods companies also have to estimate area market potentials. A common method
for calculating area market potential is the market-factor index method, which
identifies market factors that correlate with market potential and combines
them into a weighted index. The Market Rating Index(MRI) for a specific area is
given by MRI = percentage of national
retail sales in the area / percentage of national population in the area.
ESTIMATING ACTUAL SALES AND MARKET SHARES
Besides
estimating total and area demand, a company will want to know the actual
industry sales in its market. Thus, it must identify its competitors and
estimate their sales.
Industry’s trade associations often collect and
publish total industry sales, although not individual company sales. In this
way, each company can evaluate its performance against the industry as a whole.
