Customer loss and revenue loss answer different questions
Customer churn divides lost opening-cohort customers by the opening customer count. Revenue churn uses revenue lost from that same cohort. Losing one large customer and one small customer affect customer counts equally but can affect revenue very differently.
Negative net churn is possible
Gross revenue churn includes contraction and churn losses. Net revenue churn subtracts expansion from those losses. Expansion can exceed losses, making net revenue churn negative even when some customers leave. New-customer revenue is not included.
