Which metric helps assess the rate at which a company retains revenue from existing customers?

The appropriate metric for assessing the rate at which a company retains revenue from existing customers is the Retention Rate. This metric specifically measures the percentage of customers who continue to do business with the company over a given period, indicating how well a company retains its existing customer base. A high retention rate suggests that customers are satisfied with the company's products or services and are likely to continue their relationships, thereby effectively retaining revenue.

In the context of customer success, understanding the retention rate is crucial because it directly impacts overall revenue and can guide strategies to improve customer satisfaction and loyalty. By focusing on improving this metric, companies can work towards reducing churn and enhancing long-term financial stability.

Other metrics like Churn Rate reflect the percentage of customers who leave, while Net Revenue Growth tracks overall company revenue changes and Expansion Rate focuses on revenue growth from existing customers through upselling or cross-selling. However, none of these metrics directly measures how much revenue is retained from existing customers in the same focused manner as Retention Rate does.
