What Is Customer Retention Rate?
Retention Rate = (Customers at End of Period - New Customers) / Customers at Start of Period. If you start with 100 customers, add 20 new ones, and end with 105, retention is (105-20)/100 = 85%. This simple formula reveals customer loyalty. High retention means your product is working; low retention means customers are leaving for competitors.
Retention vs. Churn (Inverse Metrics)
These describe the same phenomenon:
Retention: 85% stayed = positive framing
Churn: 15% left = negative framing
In practice: Focus on retention to stay motivated; monitor churn to spot problems
Math check: Retention% + Churn% = 100%
Why Retention Matters More Than Acquisition
Revenue = Acquisition + Expansion + Retention. A 5% improvement in retention can double company profit because retained customers become expansion revenue (upgrades, cross-sells) and refer new customers. Plura's omnichannel support improves retention by providing customers with 24/7 help, reducing frustration and churn risk.
