QUESTION 2 Assume that Shannon’s decides to move forward with its loyalty / rewards program. Estimates for the cost per customer are $5.81 per month. Average customer margins, before subtracting off the cost of the loyalty / rewards program, are expected to increase to 33.91 per customer per month with a boost in retention to .82 per month. What is the resulting CLV if the annual interest rate for discounting cash flows remains the same as in Q1 (i.e. 12%)? Round your answer to the nearest penny.
where n is number of years
M is cost of retention
GC is gross contribution
d is discount rate
Now, if we are to calculate for perpetuity, i.e., infinite series
the formula would be
sum of infite geometric progreesion is a/1-x
where a is first term and and r is common ratio
in our case, a=GC*r/(1+d)
x=r/(1+d)
First term would be : (GC*r/(1+d))/(1-r/1+d) =GC*r/(1+d-r)
Similarly, second term would be M/(1+d)^0.5/(1-r/(1+d)=M*(1+d)^0.5/(1+d-r)
As given interest rate is 1% per month so annula interest would be 12%
Hence, total=33.37*12*r/(1.12-r)+5.96*12*1.120.5/(1.12-r)
This should equal to 120
Hence, back calculation gives retention rate, r = 0.1128
