Gross churn vs. net churn

Gross revenue churn is (churned MRR + contraction MRR) ÷ starting MRR. Net revenue churn subtracts expansion MRR from those losses. A negative net churn rate means expansion more than offset lost revenue.

NRR equals 100% minus net revenue churn. GRR never includes expansion and shows how much starting recurring revenue remained before upsells.
