How to Calculate Customer Lifetime from Churn Rate

Understanding and Calculating Customer Lifetime Value (CLV) from Churn Rate

Customer Lifetime Value (CLV) is a crucial metric that predicts the total revenue a business can expect from a single customer account throughout their relationship. Understanding CLV helps businesses make informed decisions about customer acquisition, retention, and marketing strategies. One of the key components in estimating CLV is the customer churn rate.

What is Churn Rate?

Churn rate, also known as attrition rate, measures the percentage of customers who stop doing business with a company over a given period. A high churn rate can significantly impact profitability, as it means a company is constantly losing existing customers while trying to acquire new ones.

How Churn Rate Affects Customer Lifetime

The churn rate is inversely related to customer lifetime. A lower churn rate implies customers stay with the company for a longer period, thus increasing their potential lifetime value. Conversely, a high churn rate suggests customers leave quickly, limiting their lifetime value.

Calculating Customer Lifetime

A simple and widely used method to estimate the average customer lifetime is by using the churn rate. The formula is:

Customer Lifetime (in periods) = 1 / Churn Rate

The "period" here depends on how you measure your churn rate. If you calculate churn monthly, your customer lifetime will be in months. If you calculate it annually, your customer lifetime will be in years.

Example Calculation

Let's say a subscription service has a monthly churn rate of 5% (or 0.05). Using the formula:

Customer Lifetime = 1 / 0.05 = 20 months.

This means, on average, a customer is expected to remain a subscriber for 20 months.
