Separating growth, retention and subscription capacity
This worksheet calculates the displayed relationship from the supplied quantities. Its label and period conventions determine how the amount should be interpreted. Recurring revenue should be compared across the same starting cohort. Expansion, contraction and churn change retention in different directions. Adding new customers to a retained-customer calculation can conceal losses in the original population.
