Customer Churn Rate

Definição

Customer churn rate is the percentage of customers who stop doing business with a company over a given period — canceling, not renewing, or lapsing — relative to the total at the start of that period.

How to calculate it

The formula is: (customers lost during the period ÷ customers at the start of the period) × 100. If you began the month with 1,000 customers and 50 left, monthly churn is 5%.

You can measure churn by customer count (logo churn) or by revenue (revenue churn), and the two can differ sharply if the customers you lose are larger or smaller than average. Churn and retention rate are complements — together they sum to 100%.

Why it matters

Churn is one of the most important health metrics for any recurring-revenue business: high churn quietly erodes growth no matter how strong acquisition is. Support quality is a major driver — customers who repeatedly hit unresolved issues or slow help are far more likely to leave — which ties CX metrics directly to revenue.

Perguntas frequentes

What is a good churn rate?

It varies by business model and segment — small-business SaaS often runs higher monthly churn than enterprise. The meaningful question is whether churn is trending down and whether your retention outweighs it for healthy net growth.

How does support affect churn?

Strongly. Slow responses, unresolved issues, and high effort push customers toward competitors, while fast, effective resolution builds the loyalty that keeps churn low.
