What this tool is for
Churn Rate Calculator is built for business planning inside business calculators when you need to shows the share of customers lost from a starting group. It focuses on churn rate instead of making you adapt a broad calculator to a narrow task.
When to use it
Use it when lost customers and starting customers are already known and you want a fast estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Lost customers is the count that the result is divided by, multiplied by, or compared against. Use customers for this field.

Formula
churn rate = lost customers / starting customers x 100

12 lost from 300 starting customers gives 4% churn.
What the result means
The result labeled "Churn Rate" is the direct output of churn rate = lost customers / starting customers x 100. In the worked example, 12 lost from 300 starting customers gives 4% churn.
Before you rely on the result
Treat the output as a planning estimate. Taxes, refunds, fees, contracts, accounting policy, and local rules can change the real business result.
