How to Calculate Churn Rate
Formula
Churn Rate = (Customers Lost / Customers at Start) x 100 Retention Rate = 100 - Churn Rate
Churn rate is the inverse of retention. It tells you what fraction of your customer base walks away during a given period (usually monthly or annually). Even small differences in churn compound dramatically: a company with 3% monthly churn loses roughly 31% of customers yearly, while 5% monthly churn means losing over 46% annually.
计算示例
A subscription business starts the month with 1,000 customers and loses 50.
- 01Churn Rate = (50 / 1,000) x 100 = 5%
- 02Retention Rate = 100 - 5 = 95%
- 03Customers Remaining = 1,000 - 50 = 950
常见问题
What is a good churn rate?
For B2B SaaS, monthly churn below 1% (roughly 12% annually) is considered healthy. For B2C, 3-5% monthly churn is common. The best companies achieve negative net churn by expanding revenue from existing customers faster than they lose it.
Should I track monthly or annual churn?
Track both. Monthly churn gives you real-time feedback on retention efforts. Annual churn paints the big picture. Be careful converting between them: annual churn is not simply monthly churn times 12 due to compounding.
