Definition

A period‑bound metric expressing the proportion of subscribers who discontinue a subscription during a specified interval, calculated by a defined formula (commonly: subscribers lost during period ÷ subscribers at period start, or alternatively ÷ average subscribers during period); measurement choices (cohort vs. snapshot, monthly vs. annual) must be stated because they change interpretation.
