Understanding Churn Rate and Customer Lifetime
Churn Rate: Churn rate (also known as customer attrition rate) is the percentage of customers lost during a specific period compared to the number of customers at the start of that period. It’s one of the most important business metrics for measuring customer retention.
Formula:
Churn Rate = (Customers Lost During Period ÷ Customers at Start of Period) × 100
Customer Lifetime (in periods): Customer lifetime is the average length of time a customer continues to do business with you before churning. It is calculated as:
Customer Lifetime = 1 ÷ Churn Rate (as a decimal)
👉 Key Insight: A lower churn rate means customers stay longer, leading to higher revenue and stronger business stability.
Formula to Calculate Churn Rate
Customer Lifetime = 1 ÷ Churn Rate (decimal)
Examples of Conversion Using the Churn Rate Calculator
Example 1:
Customers at Start = 2050 | Customers Lost = 40
Churn Rate = (40 ÷ 2050) × 100 = 1.9512%
Churn (decimal) = 0.0195122
Customer Lifetime = 1 ÷ 0.0195122 = 51.25 periods
✅ Final Results:
Churn Rate = 1.9512%
Customer Lifetime = 51.25 periods
Example 2:
Customers at Start = 1,200 | Customers Lost = 60
Churn Rate = (60 ÷ 1,200) × 100 = 5%
Churn (decimal) = 0.05
Customer Lifetime = 1 ÷ 0.05 = 20 periods
✅ Final Results:
Churn Rate = 5%
Customer Lifetime = 20 periods
Example 3:
Customers at Start = 8,000 | Customers Lost = 400
Churn Rate = (400 ÷ 8,000) × 100 = 5%
Churn (decimal) = 0.05
Customer Lifetime = 1 ÷ 0.05 = 20 periods
✅ Final Results:
Churn Rate = 5%
Customer Lifetime = 20 periods
Example 4:
Customers at Start = 4,564 | Customers Lost = 55
Churn Rate = (55 ÷ 4564) × 100 = 1.205083%
Churn (decimal) = 0.01205083
Customer Lifetime = 1 ÷ 0.01205083 = 82.98 periods
✅ Final Results:
Churn Rate = 1.205083%
Customer Lifetime = 82.98 periods
