Quick definition
Churn rate is the percentage of customers, subscribers, or followers who stop using a product or service over a given period — the inverse of retention.
Churn rate measures loss: the share of customers, subscribers, or users who leave during a defined period, expressed as a percentage. It is calculated by dividing the number who left during the period by the number you had at the start. As the mirror image of retention, churn is a critical metric for any subscription or recurring-revenue business, because sustained growth requires acquiring new customers faster than existing ones depart. A rising churn rate is an early warning that a product, price, or experience is failing to hold onto the audience it already won.
In a marketing context, churn applies beyond paid subscriptions — audiences unfollow, email subscribers unsubscribe, and app users go dormant. High follower churn after a campaign or giveaway, for example, signals that new followers were prize-motivated rather than genuinely interested. Marketers use churn to evaluate the durability of the audiences their content builds, and social teams watch for spikes in unfollows around specific content types as a sign that something is repelling the audience rather than retaining it.
Churn is best understood alongside customer lifetime value and acquisition cost: even modest reductions in churn can dramatically improve profitability because retained customers keep generating revenue without repeated acquisition spend. Common reduction levers include better onboarding, ongoing value delivery, and re-engagement of at-risk users. Because definitions and time windows vary, compare churn only against your own consistent baseline. A useful habit is segmenting churn — by plan, cohort, or acquisition channel — to find where losses concentrate rather than treating it as one flat number.
