Another indicator of the effectiveness of marketing is the average percentage of constancy of customers. Collect statistics on customers should be constantly, but if you do not have this statistics, you can use an average of 60% in the period. This figure was revealed by researchers.
For example, at the beginning of the period you had 100 customers, and then at the end of the period you will have only 60% of the initial number. Let's say you have 60 clients, after the next period you will again have 60%, but from the current value of 60 clients. This figure will be 36 customers.
Based on these data, we can predict that the client remains faithful to the business 2.5 periods. In such a simple way you can count the percentage of constancy, but it is better to prepare your statistics.
