Firm Worth The selling price of a firm is based on discounted
future profits.
Future profits are generated by customers and by customer acquisition
The firm equity aggregated from individual customer equity (customer value)

How Lifetime Value is used for acquisition and retention We need to know the value (the equity) of our
customers, for sales targeting and retention efforts
We need to discriminate among customers to acquire and retain the best
More specifically, how much money should be spent on Acquisitions Retention

What is lifetime value?
Net present value of the profit to be realized on the average new customer during a given number of years.
To compute it, you must be able to track customers from year to year.

How much to invest in retention? During Year 2
Pr. of cancelling = 30% Replacement Cost: $35.00 * 30% = $10.50 Gross profit if surviving: $3,787,500/60,000 = $63.13 Opportunity Cost if cancelled: $63.13 x 30% = $18.94 Total Expected Cost: $18.94 + $10.50 = $29.44
If 100% sure to salvage, investment < $29.44 If only 10% probability of salvage, investment < $2.94

TutorialThis weekProgram a CLV Worksheet (See Excel sheet)
Next weekUse SPSS to Estimate CLV
a) Use Survival/Life table to estimate cumulative survival rate by time period and customer segment
b) Use Compare Means to estimate annual purchasesc) Transfer data into your CLV spreadsheet
