About this calculator
This calculator computes churn rate (customers lost during a period ÷ customers at the start of the period × 100) and its complement, retention rate (1 − churn), over whatever time window you choose.
It's used by SaaS and subscription businesses tracking monthly or annual customer loss as a core health metric, product managers evaluating whether a new onboarding flow reduced drop-off, and investors sizing up a subscription company's growth sustainability before churn eats into revenue.
