Churn, at its heart, is just this: the percentage of customers you lose over a period, calculated by dividing churned customers by your starting count. The real danger is how it compounds — a seemingly harmless 5% monthly churn quietly becomes roughly 46% annually, and your average customer lifetime is simply 1 divided by your churn rate. That means every customer you lose shrinks the value of every dollar you spend getting them. The good news? Keeping a customer costs a fraction of winning a new one, and churn decisions often form weeks before the metrics show it — which is why fast, consistent follow-up matters. Every missed call or slow reply is a customer quietly deciding you're not worth waiting for. Start by calculating your own churn rate this month, then look at where customers slip away: unanswered calls, no follow-up, or leads left waiting.
