about this tool
churn rate is one of the most important metrics for any subscription-based business or service. it tells you what percentage of your customers or users are leaving over a given period — and if that number is climbing, it’s usually a sign that something in your product, pricing, or customer experience needs attention. but before you can act on churn, you need to measure it accurately.
this free churn rate calculator makes that simple. enter your number of customers at the start of a period and the number who left during that period, and the tool calculates your churn rate instantly. no spreadsheet formulas needed, no manual calculations.
it’s useful for saas founders, subscription marketers, and customer success teams who track retention as a core business metric. keeping a regular eye on your churn rate — monthly, quarterly, or annually — helps you spot trends early and understand the impact that retention has on your long-term revenue. small reductions in churn compound significantly over time, so it’s worth measuring carefully.
