Monthly Churn Rate Calculator
Calculate your monthly customer churn rate. Monthly churn is the standard SaaS metric — it tells you how quickly your customer base erodes and is the input most other metrics (LTV, runway, MRR projections) depend on.
What makes this different
- Formula: (Customers Lost ÷ Customers at Start) × 100
- B2B SaaS benchmark: 1-2% monthly
- SMB SaaS benchmark: 3-5% monthly
