Frequently Asked Questions

Churn Rate = Customers Lost ÷ Total Customers at the start of the period × 100. Retention Rate = 100% − Churn Rate.

Either — just make sure 'Customers Lost' and 'Total Customers' both refer to the same time period (e.g. both monthly, or both annual). Mixing periods will give a misleading rate.

It varies by business model — SaaS companies often target under 5-7% annual churn for enterprise customers, while consumer subscriptions may tolerate higher monthly churn. This tool doesn't benchmark your result against your industry.

No — it's a simple ratio of however many customers you count as 'lost' against your total. If you want to separate voluntary and involuntary churn, calculate each separately with this tool.
