What is Churn Rate?

Churn rate is the opposite of retention rate — it measures the percentage of customers who stop attending your classes in a given period. If your retention rate is 80%, your churn rate is 20%. While it may seem redundant to track both, framing customer loss as churn puts the focus squarely on the problem: why are families leaving, and what can you do about it?

For children's activity businesses, some churn is inevitable and healthy. Children grow out of age groups, families move house, and interests change. This "natural churn" typically accounts for 10-15% of your customer base per term. It is the "preventable churn" — families who leave because of dissatisfaction, inconvenience, poor communication, or cost concerns — that you should focus on reducing.

Analysing churn patterns reveals actionable insights. Is churn higher at certain times of year (September, when families reconsider their commitments)? Is it concentrated in specific age groups (the transition from toddler to school-age classes)? Is it higher with certain teachers or at certain venues? Do families who attend fewer than three sessions in their first term churn at higher rates? This kind of analysis enables targeted interventions: a re-engagement email series for at-risk families, improved onboarding for new joiners, or additional training for teachers whose classes have above-average churn.
