What Is Churn Rate?
Churn rate measures the percentage of customers or revenue lost during a specific period. It is the core metric that customer success teams exist to reduce.
Churn rate comes in two flavors: logo churn (percentage of customers lost) and revenue churn (percentage of recurring revenue lost). Both matter, but they tell different stories. A company could lose 10% of its logos but only 2% of revenue if the churned accounts were small.
For logo churn: divide the number of customers lost in a period by the number of customers at the start of the period. For revenue churn: divide lost MRR by starting MRR. Monthly and annual calculations are both common, but be careful when annualizing monthly rates because churn compounds.
Benchmarks depend heavily on market segment. Enterprise SaaS companies with annual contracts often see 5-7% annual logo churn. SMB products with monthly billing can see 3-5% monthly churn, which annualizes to 30-45%.
Types of Churn
Voluntary churn happens when customers actively decide to leave. Involuntary churn happens due to expired credit cards, billing failures, or administrative oversights. The distinction matters because the solutions are different. Voluntary churn requires product improvement and better CS engagement. Involuntary churn requires dunning flows and payment recovery systems.
Why CS Teams Own Churn
Customer success was created specifically to reduce churn. Every activity a CSM performs, from onboarding to QBRs to health monitoring, ultimately ties back to keeping customers. CS leaders report churn metrics to the board more than any other number.
Reducing churn by even a few percentage points has massive impact. A SaaS company doing $10M ARR that reduces annual churn from 15% to 10% retains an extra $500K per year, compounding over time. This is why CS teams are a revenue function, not a cost center.

Frequently Asked Questions
What is an acceptable churn rate for SaaS?
For enterprise SaaS, annual churn below 10% is considered healthy. For SMB SaaS, monthly churn below 3% is a common target. The acceptable rate depends on ACV, contract length, and market maturity. This is a common area of focus for customer success teams working to improve their approach to Churn Rate.
What is the difference between gross churn and net churn?
