## Understanding Churn Rate

### What is Churn Rate?

Churn rate measures the percentage of customers who stop subscribing during a given time period. It's one of the most critical metrics for subscription businesses because it directly impacts revenue growth and customer lifetime value.

### Why Churn Matters

Even small improvements in churn rate have compounding effects. A 1% reduction in monthly churn can increase your customer lifetime by 10-20%. This means more revenue without increasing acquisition spend.

### Types of Churn

#### Voluntary Churn

Customers who actively cancel—usually due to value perception, budget, or competition.

#### Involuntary Churn

Customers lost due to failed payments, expired cards, or technical issues—often recoverable.
