Revenue Churn
The percentage of recurring revenue lost due to cancellations and downgrades over a specific period.
FORMULA
Gross Revenue Churn = (Churned MRR + Contraction MRR) / Starting MRRWhy it matters
Revenue Churn is the direct inverse of Gross Revenue Retention. It quantifies the exact financial impact of customers leaving the platform or reducing their spend. High revenue churn is an existential threat to a SaaS business because it dictates the amount of new ARR the sales team must generate just to keep top-line revenue flat. If a company with $10M ARR has 15% revenue churn, it must sell $1.5M in new business annually just to tread water. Reducing revenue churn through customer success initiatives is almost always the highest-ROI activity for a scaling software company.
2025 BENCHMARK
Benchmarkit Q4 2025 data indicates median annual gross revenue churn sits at 11.5% for B2B SaaS companies.
COMMON MISTAKES
- Netting out expansion revenue against churn (which creates Net Churn, a different metric).
- Failing to annualize monthly churn rates when reporting to the board.
- Ignoring contraction MRR and only counting full cancellations.
