What is Churn?
The loss of customers or revenue over a given period, representing the rate at which people stop using or paying for your product.
Understanding the Details
Churn is the silent killer of SaaS businesses. While acquisition gets the attention, churn determines whether growth is sustainable. A company adding 100 customers per month with 5% monthly churn will plateau at 2,000 customers regardless of how much they spend on acquisition. Churn can be measured as logo churn (number of customers lost) or revenue churn (amount of revenue lost), and the two can tell different stories. Losing many small customers might have less revenue impact than losing one enterprise account. Understanding why customers leave — through exit surveys, usage analysis, and win-back conversations — is the first step to reducing churn systematically.
How It Works in Practice
Cohort-based churn tracking
Monthly cohort analysis reveals that Q4 signups churn at 2x the rate of Q2 signups, pointing to a seasonal quality issue in lead sources.
Usage-based churn prediction
A model identifies that accounts with less than 3 weekly logins are 80% likely to churn within 60 days, enabling proactive intervention.
Churn reason categorisation
Exit survey analysis shows 40% of churn is due to missing features, 30% to budget cuts, and 30% to poor onboarding, guiding investment priorities.
Why It Matters
Churn caps your growth ceiling. No matter how fast you acquire customers, high churn means you're filling a leaky bucket. Reducing churn is often the most efficient path to faster growth.
What People Often Get Wrong
Some churn is acceptable. Actually, while zero churn is unrealistic, the acceptable level depends entirely on your growth rate and economics.
Churn is a customer success problem. Actually, churn often starts with poor-fit acquisition, bad onboarding, or product gaps.
Offering discounts fixes churn. Actually, discounts treat the symptom, not the cause, and often delay rather than prevent cancellation.
