Churn Rate
Churn rate is the percentage of customers who stop using a product or service within a given time period. It's a critical metric for subscription-based businesses, especially SaaS, where recurring revenue depends on customer retention.

Why It Matters
SaaS relies on recurring revenue, so high churn nullifies new customer acquisition efforts. A 5% monthly churn rate means losing nearly half your customer base annually. Retaining existing customers is 5–7x cheaper than acquiring new ones — making churn management foundational to profitability.
Formula
Churn Rate = (Customers lost during period ÷ Customers at period start) × 100
Example: Starting with 1,000 customers and losing 50 over a month = 5% monthly churn.
Subscription businesses measure churn monthly, quarterly, and annually.
SaaS Benchmarks
| Monthly Churn | Level |
|---|---|
| Under 1% | World-class |
| 1–3% | Excellent |
| 3–5% | Healthy |
| 5%+ | Needs improvement |
Types of Churn
Customer churn: Percentage of customers lost — counts the number of departures.
Revenue churn: Percentage of revenue lost — if high-tier customers churn disproportionately, revenue churn can far exceed customer churn.
How to Reduce Churn
Improve onboarding: Help new customers reach value quickly. The first 30 days determine long-term retention.
Proactive communication: Regular check-ins surface problems early. 67% of churn is preventable if issues are resolved at first contact.
Customer Success: Dedicated teams help customers achieve their goals and intervene proactively with at-risk accounts.
Feedback loops: Systematically collect reasons for cancellation to improve product and service.
