Churn Rate

Churn rate indicates what share of customers or revenue is lost over a given period. It shows how many customers leave or cancel contracts. A low churn rate indicates satisfied, loyal customers and a stable business.

Two views must be distinguished: logo churn counts lost customers regardless of size, while revenue churn measures the value of revenue lost. The two can diverge sharply, for example where many small customers leave but large ones stay, making logo churn look high and revenue churn low. The reference period also matters, since a monthly rate of two percent equates to roughly a fifth of the base over twelve months and is therefore far more serious than the small figure suggests. The metric is complemented by net revenue retention, which nets off expansion within the existing base and can therefore exceed 100 percent where upsell more than offsets losses. Assuming constant customer churn, average customer lifetime can be approximated by the inverse of churn, feeding directly into customer lifetime value.

In transactions churn is one of the most important value drivers, because it determines how much of today's revenue survives into later years without new sales effort. Cohort analyses over several years, the distribution by customer size and segment, and the question whether churn is kept artificially low through price concessions are therefore examined closely. Voluntary and involuntary churn should also be distinguished, because part of the losses stems from insolvencies, takeovers or payment defaults rather than dissatisfaction. That separation matters for forecasting, since the two causes respond to different measures. The timing of cancellations within the customer lifecycle is also informative, because a cluster shortly after contract start points to problems with expectation management or onboarding, while late cancellations tend to reflect competition or price.
