What is Churn?
The rate at which customers stop buying from you or cancel their subscription. Monthly churn rate is the percentage of customers lost per month. Reducing churn by 1% can increase LTV by 5-10%.
Measuring churn
Monthly churn rate = customers lost in a month / customers at the start of the month. A 5% monthly churn rate means you lose half your customer base in 13 months. For subscription brands, churn is the single most important metric after acquisition. A 1% reduction in monthly churn from 5% to 4% increases average customer lifetime from 20 months to 25 months, a 25% increase in LTV. Small churn improvements compound dramatically.
Churn causes by category
Product-market fit churn: the customer tried your product and it was not for them (hardest to fix). Price sensitivity churn: the customer likes your product but found a cheaper alternative. Engagement churn: the customer forgot about you (most fixable with marketing). Involuntary churn: payment failed, card expired (recoverable with dunning flows). Most DTC subscription brands see 40-60% of churn from engagement and involuntary causes, both addressable.
Creative strategies to reduce churn
Retention-focused ad creative targets existing customers with content designed to reinforce value: how-to content showing new uses, customer success stories from long-term users, new product announcements, and exclusive loyalty offers. Retargeting lapsed customers with "we miss you" creative and a return incentive recovers 10-20% of churned customers. AI tools generate this retention creative from your existing customer data and Brand DNA.
