churn rate
A magical number indicating the proportion of customers who have lost faith, inviting both executive nightmares and budget meetings. Every month, a ritual is performed of staring at the churn rate, praying, and then tasting defeat. If it's low, there's a momentary calm; if it's high, a red warning light illuminates the office. Yet in either case, the true reckoning comes with the cruel update of next month's figure. In short, churn rate is the black mirror of the business world, shuttling hope and despair.
