Churn rate is the #1 metric every SaaS founder needs to obsess over. A high churn rate means you're losing customers faster than you're acquiring them — and that's a business death spiral.
What Is SaaS Churn Rate?
Customer Churn Rate = (Customers Lost in Period / Customers at Start of Period) × 100
For example, if you started the month with 200 customers and lost 10, your monthly churn rate is 5%.
Why It Matters More Than Acquisition
Most founders focus on growth (new customers), but churn is the silent killer:
- A 2% monthly churn = 22% annual churn — you're replacing a fifth of your customer base every year
- A 5% monthly churn = 46% annual churn — half your customers leave every year
- Even at 1% monthly churn, you lose 11.4% annually
Types of Churn
| Type | What It Measures |
|---|---|
| Customer Churn | % of customers who cancel |
| Revenue Churn | % of MRR lost |
| Net Revenue Churn | Revenue lost minus expansion revenue |
