Churn rate is the percentage of customers who stop doing business with you at the end of a period. It is the opposite of renewal rate, and shows how much revenue you are losing from customer attrition. A high churn rate indicates that your customers are dissatisfied, unhappy, or unengaged with your products or services, and are likely to switch to your competitors. To use churn rate to prevent losing partners, you need to monitor your churn rate regularly, and identify the root causes of customer churn. You can also segment your customers based on their churn risk, such as low, medium, or high, and design different retention strategies for each group. For example, you can offer incentives, discounts, or upgrades to low-risk customers, provide more support, feedback, or education to medium-risk customers, and re-engage, re-negotiate, or re-sell to high-risk customers.
