Revenue churn rate measures the percentage of recurring revenue (MRR or ARR) lost in a period due to cancellations and downgrades, before accounting for expansion. It captures the dollar impact of retention failures, weighting each lost customer by their revenue contribution rather than treating all accounts equally.
Revenue Churn Rate = (MRR Lost to Cancellations + MRR Lost to Downgrades) / MRR at Period Start × 100
$100,000 MRR at period start. $3,000 in cancellations. $1,500 in downgrades.
($3,000 + $1,500) / $100,000 × 100
→ 4.5% gross revenue churn — $4,500 in MRR must be replaced before you grow at all.
Revenue churn is the financial reality of customer churn. Two companies with identical 5% customer churn rates can have wildly different revenue churn rates depending on which customers are leaving. Losing your lowest-value customers is painful but survivable. Losing your highest-value accounts is an existential threat.
For B2B SaaS, revenue churn is what your investors actually care about. A 1% monthly revenue churn rate against a strong expansion motion can produce a business that grows despite losing customers. A 5% monthly revenue churn rate with flat expansion produces a business in secular decline regardless of sales performance.
Always decompose revenue churn into cancellation churn and downgrade churn. Cancellation churn is a product-market fit signal. Downgrade churn is a value delivery and pricing signal. The interventions are completely different.
the mrrsucks take
Revenue churn is your product voting with its wallet. Every point of MRR churn is a customer telling you they found something better — or nothing at all is preferable to what you built.
Yes, effectively. MRR churn is revenue churn expressed against your monthly recurring revenue base. They are the same concept measured at monthly vs annual cadence.
NRR (Net Revenue Retention) = 100% minus revenue churn plus expansion rate. If your gross revenue churn is 8% but your expansion rate is 12%, your NRR is 104% — meaning your existing customers grow your revenue even as some leave.
