How many times a contract has renewed before this one: first renewals lose most, and the rate is compared within the number.
Renewal number is the count of prior terms a contract has completed. First renewals run ten to twenty points below third renewals on most desks, because the customer is still deciding. A base with many new contracts has a lower blended renewal rate for that reason alone, so the rate is computed and compared within each renewal number.
Each contract carries the count of prior terms it has completed. Renewal rates are computed and compared within each count, because first renewals behave differently.
First renewals run at 85 percent and third renewals at 97. A base with many new contracts has a lower blended rate for that reason alone.
A fast-growing base judged against a mature one on a blended rate.
