Customer Churn Risk Calculator
Calculate the financial impact of customer churn on your business
How it's calculated
- Definition
- Churn cost is the recurring revenue that leaves with churned customers, plus the acquisition spend needed to replace them.
- Formula
- Customers lost per year = customers × monthly churn rate × 12. Churn cost = customers lost × average annual revenue per customer, plus customers lost × acquisition cost to replace them.
- Benchmark
- There's no universal benchmark; compare the result with your retention budget. If churn costs ten times what you spend on retention, the business case writes itself.
Our take
This is the number that gets CX budgets approved. Finance rarely reacts to an NPS drop, but it reacts to revenue walking out of the door.

Frequently Asked Questions
How do I calculate the cost of customer churn?
Multiply the customers you lose per year by the average annual revenue per customer, then add what it costs to acquire replacements.
Is it cheaper to keep a customer than acquire one?
Usually, because acquisition costs repeat for every replacement. Use your own acquisition cost in the calculator to see the gap for your business.
