Churn Rate Calculator — SaaS Customer Retention Tool

Calculate customer churn rate, MRR lost to churn, customer LTV impact, and how much revenue you're losing annually. Stop churn before it kills your SaaS.

Practical example: 500 customers, 10 churned. For a early saas scenario, enter the values that match your situation to get an instant cost estimate.

What churn rate is acceptable? Monthly churn under 1% (12% annual) is good for most SaaS. Under 0.5% monthly (6% annual) is best-in-class. Enterprise SaaS typically achieves 0.2-0.5% monthly churn due to longer contracts and stickier products.

Formula: churnRate = (lostCustomers / startCustomers) × 100 | mrrChurned = mrr × (churnRate / 100) | customerLTV = (mrr / startCustomers) / (churnRate / 100)
