Gross Revenue Churn

Measured as

Gross revenue churn = (contraction MRR + churned MRR) / starting MRR

Misused when

• Including expansion (gross churn excludes it).
• Mixing cohorts or time windows (start from one cohort, losses from another).
• Using ending MRR as the denominator instead of starting MRR.

Operator takeaway

• It's a loss metric (how much revenue you lost), not a remaining metric.
• Use the same cohort and time window for starting MRR and losses.
• Track gross churn alongside GRR/NRR to avoid being misled by expansion.
• Keep Gross Revenue Churn consistent by cohort, segment, and period before you use it as a decision signal in planning or reporting.
• Interpret the metric alongside retention, margin, or payback so one ratio does not hide the real operating trade-off.
