Churn Rate Calculator

This calculator helps you determine your business's churn rate, essential for understanding customer retention and optimizing your marketing and sales strategies.

Calculate Churn Rate

Initial Customers *

Remaining Customers *

Results

Churn Rate: 0%

Data Source and Methodology

All calculations are based rigorously on standard business formulas for churn rate. Consult authoritative business analytics resources for more information.

The Formula Explained

The churn rate formula is given by:

Churn Rate = (Initial Customers - Remaining Customers) / Initial Customers × 100%

Glossary of Variables

Initial Customers: The number of customers at the start of the period.
Remaining Customers: The number of customers at the end of the period.
Churn Rate: The percentage of customers who have left the service over the period.

How It Works: A Step-by-Step Example

Suppose you start with 200 customers and end with 180 after a month. The churn rate is calculated as:

Churn Rate = (200 - 180) / 200 × 100% = 10%

Frequently Asked Questions (FAQ)
