The Mathematics
// RETAINED CUSTOMERS ALGORITHM
RetainedCustomers = CustomersAtEnd - NewCustomers
// RETENTION RATE VECTOR
RetentionRate = (RetainedCustomers / CustomersAtStart) * 100
"Retention rate isolates organic loyalty by subtracting newly acquired customers from the end-of-period total. This reveals the true proportion of your original cohort that remained active throughout the measurement window."
