RFM (Recency, Frequency, Monetary) score is a method used in customer segmentation to determine the value of customers based on their historical behavior. The score is calculated by taking into account the recency of the customer’s last purchase (Recency), the frequency of their purchases (Frequency), and the monetary value of their purchases (Monetary).

The RFM score can help companies identify their most valuable customers, as well as those who are at risk of churning. For example, a customer who has made a recent purchase, has a high frequency of purchases, and has a high monetary value would be considered a “high value” customer and would receive a higher RFM score. On the other hand, a customer who has not made a purchase in a long time, has a low frequency of purchases, and has a low monetary value would be considered a “low value” customer and would receive a lower RFM score.

It is important because by identifying the most valuable customers, companies can focus their marketing efforts on retaining and growing these customers, which can lead to increased revenue and growth. Additionally, by identifying customers at risk of churning, companies can take steps to prevent them from leaving, such as offering incentives or targeted marketing campaigns.
