Churn rate (sometimes called attrition rate), in its broadest sense, is a measure of the number of individuals or items moving out of a collective over a specific period of time. It is one of two primary factors that determine the steady-state level of customers a business will support. The term is used in contexts, but is most widely applied in business with respect to a contractual customer base. For instance, it is an important factor for any business with a subscriber-based service model, including mobile telephone networks and pay TV operators. The term is also used to refer to participant turnover in peer-to-peer networks.
The phrase is based on the English verb churn, meaning "to agitate or produce violent motion".

Famous quotes containing the words rate and/or churn:
“We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
—Max Lerner (b. 1902)
“the churn of stale words in the heart again
love love love thud of the old plunger”
—Samuel Beckett (19061989)
