Assume that Shannon’s decides to move forward with its loyalty / rewards program. Estimates for the cost per customer are $5.41 per month. Average customer margins, before subtracting off the cost of the loyalty / rewards program, are expected to be 33.95. Assuming that Shannon’s wishes to obtain a minimum CLV of $120, what is the required retention rate that must be achieved? Assume that the interest rate is 1% per month. Compute your answer to the nearest 1/100 of a percent e.g. 50.13%. However, do not include the % symbol.
