Renewal Rate ~ (count form "gross renewal rate"; value form "dollar renewal rate")

Base and timing fork, plus confusion with retention. Base: count renewal rate

(contracts renewed over contracts up for renewal) vs dollar renewal rate (ARR

renewed over ARR up for renewal), a book can renew 90% of contracts but only

78% of dollars if big accounts leave. Timing: on-time renewals only vs

eventual renewals (a deal that closes two months late), a snapshot at the

renewal date understates, a trailing measurement recovers it. And renewal rate

is often conflated with retention rate, but retention spans all customers

while renewal rate only concerns those in the renewal window.
