Starbucks customer satisfaction has been reported as high as 85%. Because of this, the company has always experienced high retention rates. They are planning to implement a new promotion campaign, aimed to reach a new target market a customer segment they have previously neglected (i.e. 11.75 million people). They plan to invest 34,500,000$ on the campaign in the first year. Given that their past data indicates that it costs 40% less to keep an existing customer than to acquire a new one, they expect that their advertising campaign budget will be 40% less in year 2 (than in year 1). They are expected to convert 1/3 of the market.

Projections for Year 1 of the campaign

They expect that customers will spend approximately $4.19 per visit, and that the customer is likely to visit a Starbucks every two weeks. Contribution margin: 38% *assume 52 week in one year

Projections for Year 2 of the campaign

They expect that customers will spend approximately $5.73 per visit, and that the customer is likely to visit a Starbucks three times per month. Contribution margin: 38.7%

The marketing analytics team is optimistic about reaching a high Customer Lifetime Value with this particular market. They aim to gain a total CLV of $100.00 within a two year period.

Question: If they want to achieve their CLV objective, what percentage of customers do they have to retain in year 2 (whats the retention rate)?
