Churn is the enemy of SaaS growth. Master the metrics that measure it, diagnose its causes, and track your progress in reducing it — with clear definitions, formulas, and examples.
This glossary covers the essential churn metrics: how churn rate is calculated, what churn analysis tells you, how to predict churn before it happens, and the tools that help manage it. Master these metrics and you'll be equipped to build a more resilient SaaS business.
Churn Rate is the percentage of customers (or revenue) you lose during a specific time period, typically expressed as a monthly or annual rate.
Churn rate is the inverse of retention rate. If you retain 90% of customers, your churn rate is 10%. It's measured by customer count or by revenue (MRR/ARR).
Month 1: 100 customers
4 customers churned
Monthly Churn Rate = 4 / 100 × 100 = 4%
Churn Analysis is the process of investigating why customers are churning and identifying patterns or root causes.
It goes beyond just measuring churn rate — it asks "why?" Are customers leaving because of price, product issues, support quality, or market fit?
| Dimension | What You Measure | Action |
|---|---|---|
| Cohort Churn | Churn by customer acquisition month | Identify if certain cohorts are stickier |
| Segment Churn | Churn by industry, company size, use case | Find problem segments |
| Plan Churn | Churn by pricing tier | Fix pricing or positioning |
| Feature Usage | Engagement of churners vs. retained | Identify adoption gaps |
Example 1: Enterprise segment has 2% monthly churn, but SMB has 6%. Action: Improve SMB onboarding and support.
Example 2: Customers on the free trial who don't complete onboarding have 80% churn. Action: Improve first-week user experience.
Churn Calculation refers to the process and method of computing your churn rate accurately, including proper accounting for different customer types and timing.
Downgrades: Should downgrades count as churn? Depends on your business model. Often measured separately as "contraction churn."
Pauses: If you offer account pauses, should they count as churn? Usually not, but track them separately.
Mid-period signups: Use a cohort approach or pro-rata calculations for mid-period additions.
November metrics:
Starting customers: 500
Churned: 15
New signups: 30
Churn Rate = 15 / 500 × 100 = 3%
(Don't include the 30 new signups in the denominator)
Churn Prediction uses data and machine learning to forecast which customers are at risk of churning before they actually cancel.
Instead of reacting to churn after it happens, prediction lets you proactively intervene with at-risk customers.
| Indicator | What It Means | Action |
|---|---|---|
| Declining usage | Feature engagement dropping month-over-month | Reach out with re-engagement content |
| Support tickets | Spike in support tickets from a customer | Proactive support intervention |
| Inactivity | Customer hasn't logged in for 30+ days | Send win-back campaign |
| Payment issues | Failed payment, declined card | Update payment method, offer help |
