Calculator guide
Measure customer churn, retention, and ending subscribers. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Customer churn percentage = customers lost during the period ÷ customers at the beginning of the period × 100.
How to use this calculator
- Set Customers at Start. The interface starts with 1000; replace it with the value for your scenario.
- Set Customers Lost. The interface starts with 45; replace it with the value for your scenario.
- Set New Customers. The interface starts with 80; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Customers at Start = 1000; Customers Lost = 45; New Customers = 80. With those assumptions, the calculator gives Customer Churn Rate: 4.5%; Retention Rate: 95.5%; Ending Customers: 1,035. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Customer Churn Rate is 4.5%. Retention Rate is 95.5%. Estimates exclude charges and rules not represented by the inputs. Rates and prices are assumptions; results are not a quote or guaranteed return.
Limitations and assumptions
