Churn Rate
The percentage of customers who cancel or do not renew within a given period. High churn erodes MRR growth and increases CAC payback period, making retention optimisation as important as acquisition for sustainable growth.
How Churn Rate works in practice
Monthly churn above 5% means losing over 46% of the customer base annually, making sustained net growth nearly impossible without an exceptionally efficient acquisition engine. The distinction between gross churn (percentage of customers lost) and net revenue retention (accounting for expansion MRR from remaining customers) is critical — a business can have 10% gross churn but 110% net revenue retention if upsells from retained customers exceed the revenue lost to churn. Cohort analysis of churn by acquisition channel, pricing plan, onboarding path, and customer segment identifies which segments have the highest retention and should receive the most acquisition investment. Reducing churn by 1 percentage point increases LTV significantly — for a £100 MRR customer at 5% monthly churn, reducing churn to 4% increases LTV from £2,000 to £2,500 (25% increase).
