Scope

Upsell potential depends on adoption quality

This calculator estimates expansion revenue from the assumptions entered. Upgrade and add-on purchases can overlap, so expected purchase events are not unique customers. The model does not automatically include churn caused by price increases, cannibalization of existing products, capacity constraints, taxes, delayed adoption, financing cost or changes in customer lifetime unless those effects are reflected in the inputs. Forecast revenue is potential revenue, not guaranteed bookings or recognized accounting revenue.
