across all customers in the given market
• Measured in percentage
• Calculated either on a monetary or volumetric basis
– Market Share (%) of a firm (j) in a category =
Where j = firm, S = sales, Sj = sum of sales across all firms in the market
Information source
Numerator: Sales of the local firm available from internal records
Denominator: Category sales from market research reports or competitive intelligence
Evaluation

MARKET SHARE AND GROWTH
Market share, in strategic management and marketing is, the percentage
or proportion of the total available market or market segment that is being
serviced by a company. It can be expressed as a company's sales revenue
(from that market) divided by the total sales revenue available in that
market. It is generally necessary to commission market research(generally
desk/secondary research) to determine , although sometimes primary
research) to estimate the total market size and a company's market share.
Increasing market share is one of the most important objectives of
business.
Market Growth , An increase in the demand for a particular product or
service over time. Market Growth can be slow if consumers do not adopt a
high demand or rapid if consumers find the product or service useful for
the price level. For example, a new technology might only be marketable to
a small set of consumers, but as the price of the technology decreases and
its usefulness in every day life increases, more consumers could increase
demand.
SUHAS ARADHYE
Module 2010
Reason For Market Share
Reasons to Increase Market Share
Market share often is associated with profitability and thus many firms seek
to increase their sales relative to competitors. Here are some specific
reasons that a firm may seek to increase its market share:
Economies of scale - higher volume can be instrumental in developing a
cost advantage.
Sales growth in a stagnant industry - when the industry is not growing,
the firm still can grow its sales by increasing its market share.
Reputation - market leaders have clout that they can use to their
advantage.
Increased bargaining power - a larger player has an advantage in
negotiations with suppliers and channel members.

Acquisition Cost
SUHAS ARADHYE
Module 2010
Acquisition Rate
• Acquisition defined as first purchase or purchasing in the first predefined period
• Acquisition rate (%) = 100*Number of prospects acquired / Number of prospects
targeted
• Denotes average probability of acquiring a customer from a population
• Always calculated for a group of customers
• Typically computed on a campaign-by-campaign basis
Information sourceNumerator: From internal records
Denominator: Prospect database and/or market research data
EvaluationImportant metric, but cannot be considered in isolation
SUHAS ARADHYE
Module 2010
Acquisition Cost
• Measured in monetary terms
• Acquisition cost ($) = Acquisition spending ($) / Number of prospects acquired
• Precise values for companies targeting prospects through direct mail
• Less precise for broadcasted communication
Information source:
• Numerator: from internal records
• Denominator: from internal records
Evaluation:
• Difficult to monitor on a customer by customer basis

Customer Activity Measurements
Objectives
Managing marketing interventions
Align resource allocation with actual customer to demonstrate how knowledge
of customer activity adds to shareholder value behavior
Key input in customer valuation models such as Net-present Value (NPV)

Average Inter-purchase Time (AIT)
SUHAS ARADHYE
Module 2010
Average Inter-purchase Time (AIT)
• Average Inter-purchase Time of a customer
= 1 / Number of purchase incidences from the first purchase till the current time period
• Measured in time periods
• Information from sales records
• Important for industries where customers buy on a frequent basis
Information sourceSales records
Evaluation:Easy to calculate, useful for industries where customers make frequent purchases
Firm intervention might be warranted anytime customers fall considerably below their AIT

Retention Rate
& Defection Rate
SUHAS ARADHYE
Module 2010
Retention and Defection
• Retention rate (%) = 100* Number of customers in cohort buying in (t)| buying
in (t-1) / Number of customers in cohort buying in (t-1)
• Avg. retention rate (%) = [1 – (1/Avg. lifetime duration)]
• Avg. defection rate (%) = 1 – Avg. Retention rate
• Avg. retention rate (%) = 1 – Avg. defection rate
• Avg. lifetime duration = [1/ (1- Avg. retention ratet)
• Assuming constant retention rates, number of retained customers in any
arbitrary period (t+n) = Number of acquired customers in cohort * Retention
rate (t+n)
• Given a retention rate of 75%, variation in defection rate with respect to
customer tenure results in an average lifetime duration of four years
SUHAS ARADHYE
Module 2010
Retention and Defection-Example
• If the average customer lifetime duration of a group of customers is 4 years,
the Average retention rate is 1- (1/4) = 0.75 or 75% per year. i.e., on an
average, 75% of the customers remain customers in the next period
• The effect for a cohort of customers over time – out of 100 customers who
start in year 1, about 32 are left at the end of year 4
Customers starting at the beginning of year 1: 100
Customers remaining at the end of year 1: 75 (0.75*100)
Customers remaining at the end of year 2: 56.25 (0.75*75)
Customers remaining at the end of year 3: 42.18 (0.75*56.25)
Customers remaining at the end of year 4: 31.64 (0.75*42.18)
Assuming constant retention rates, the number of retained customers at the
end of year 4 is 100*0.754 = 31.64. (Number of acquired customers in cohort *
Retention rate (t+n) )
The defection rate is 1-0.75 = 0.25 or 25%

Life Time Duration
& Survival Rate
SUHAS ARADHYE
Module 2010
Customer Lifetime Duration
• Average Lifetime duration = Customers retainedt * Number of periods / N
Where: N = cohort size, t= time period
• Differentiate between complete and incomplete information on customer
– Complete information - customer‟s first and last purchases are assumed to
be known
– Incomplete information- either the time of first purchase, or the time of the
last purchase, or both are unknown
T

SUHAS ARADHYE
Module 2010
• Customer relationships
– Contractual (“lost-for-good”): Lifetime duration is time
from the start of the relationship until the end of the
relationship (e.g.: mobile phone contract)
– Non-contractual (“always-a-share”): Whether
customer is active at a given point in time (e.g.:
department store purchase)
– One-off purchases

Module 2010
Survival Rate
• Measured for cohorts of customers
• Provides a summary measure of how many customers survived between the
start of the formation of a cohort and any point in time afterwards
• Survival ratet (%) = 100*Retention ratet * Survival ratet-1
• Number of Survivors for period 1 = Survival Rate for Period 1 * number of
customers at the beginning
SUHAS ARADHYE
Module 2010
Survival Rate Computation-Example
Number of Customers starting at the beginning of year 1: 1,000
Retention rate Survival rate Survivors
Period 1: 0.55 0.55 550
Period 2: 0.62 0.341 341
Period 3: 0.68 0.231 231
Period 4: 0.73 0.169 169
Number of Survivors for period 1 = 0.55 * 1000 = 550
Survival rate for period 2 = Retention rate of period 2 * Survival Rate of Period 1.
Therefore, Survival rate for period 2 = 0.62 * 0.55 = 0.341 (=34.1%)
SUHAS ARADHYE
Module 2010
Projecting Retention Rates
• To forecast non-linear retention rates,
Rrt = Rrc * (1-exp(-rt))
where: Rrt is predicted retention rate for a given
future period,
Rrc is the retention rate ceiling
r is the coefficient of retention
• r = (1/t) * (ln(Rrc) – ln(Rrc – Rrt ))

Rrc = 0.95 means that managers believe that the maximum attainable retention rate is 95%
The known retention rate in period 9 is 80% while the one in period 10 is 82%.
The parameter r for period 9 is (1/9)*(ln(0.95)-ln(0.95-0.8)) = 0.205. The r for period 10 is (1/10)*(ln(0.95)-
ln(0.95-0.82)) = 0.198. --for both periods r approximates the value 0.2.

Share of wallet
• % Share of a customers expenses (of wallet) for a product that goes to the firm by selling the product.
• It helps the manager to understand the amount of business a company gets from specific customer.
• Different firms fight over the share they have of a customers wallet, all trying to get as much as possible.

How to increase the sow
• Cross selling
• Invest in those activities which prompt

Key tasks after knowing the SOW
• Exploring new means to increase the
budget and their spending.
• Profile the ideal/main customers.
• Places that need to be focused for
improvement to get competitive edge.
• To retain the best customers.
SUHAS ARADHYE
Module 2010
Calculation of SOW
• A given brand‟s share of purchase in its
category, measured solely among
customers who have already purchased
that brand.
• Share of wallet (in units)= BRAND PURCHASED/TOTAL CATEGORY
PURCHASED
SUHAS ARADHYE
Module 2010
Example
• Category-sunscreen
• BRANDS :
LAKME,LOTUS,HIMALAYA,GARNIER,L‟OREAL
• Calculate SOW for lakme.
• If customers have purchased 1000 bottles
of lakme sunscreen and total
category(sunscreen) purchases are 2000
bottles then………………
SUHAS ARADHYE
Module 2010
• SOW= brand purchased(lakme)/total
category purchased(sunscreen)
=1000/2000 =50%
So the sow for lakme is 50%.

Applications of SCR and SW
• SCR -for categories where the variance of customer expenditures is relatively small
• SW - if the variance of consumer expenditures is relatively high
• Share-of-wallet and Size-of-wallet simultaneously – with same share-of-wallet,
different attractiveness as customers:
Example:
Share-of-Wallet Size-of-Wallet Absolute expenses
with firm
Buyer 1 50% $400 $200
Buyer 2 50% $50 $25
Absolute attractiveness of Buyer 1 eight times higher than buyer 2
