Revenue Churn
Revenue churn (also called MRR churn) is the percentage of recurring revenue lost from existing customers in a given period due to cancellations and downgrades. It measures the rate at which your revenue base erodes.
Also known as: MRR churn, revenue churn rate, dollar churn
Formula
(Churned MRR / Starting MRR) x 100
Why It Matters
Revenue churn is distinct from customer (logo) churn because not all customers are worth the same. Losing one enterprise customer paying $10,000/month has the same revenue churn impact as losing 100 customers paying $100/month, but very different logo churn implications. Revenue churn captures the financial magnitude of losses.
This metric directly determines whether your business can grow efficiently. A 5% monthly revenue churn rate means you lose half your revenue base in a year. You would need to add that much in new business just to stay flat. At 2% monthly churn, annual revenue loss is more manageable at about 21%, and at 1%, only about 11%.
Revenue churn also has a compounding effect that makes it urgent. Each month's churn base is smaller than the last (assuming churn exceeds growth), but the cumulative impact accelerates. Companies that let revenue churn creep up often find that by the time it becomes alarming, significant remediation is needed.
How to Calculate
Sum all recurring revenue lost from cancellations and downgrades during the period. Divide by the starting MRR at the beginning of the period. Multiply by 100 to express as a percentage. For gross revenue churn, exclude expansion revenue. For net revenue churn, subtract expansion revenue from the lost amount (net revenue churn can be negative when expansion exceeds losses).

Industry Applications
A SaaS company discovers that its monthly revenue churn is 3.5%, primarily driven by SMB customers on monthly plans. By offering annual plan discounts, they shift 40% of SMB customers to annual billing and reduce revenue churn to 2.1%.
Benchmark: Best-in-class SaaS monthly revenue churn: <0.5% enterprise, <1% mid-market, <2% SMB
A subscription box company tracks revenue churn by product category and finds that their premium tier has 50% lower revenue churn than the basic tier, supporting a strategy to migrate customers up-market.
Benchmark: Subscription ecommerce typically sees 5-10% monthly revenue churn; premium offerings churn less
How to Track in KISSmetrics
KISSmetrics tracks revenue churn by monitoring cancellation and downgrade events tied to individual customer accounts. Use cohort analysis to see churn patterns by customer age, acquisition source, and plan tier. Set up automated alerts when monthly revenue churn exceeds your target threshold so you can investigate and intervene quickly.
Common Mistakes
- -Conflating revenue churn with logo churn - they tell different stories and require different solutions
- -Not distinguishing between voluntary churn (customer cancels) and involuntary churn (payment failure) since they need different interventions
- -Calculating revenue churn annually when monthly tracking catches problems much earlier
- -Including seasonal or one-time revenue fluctuations in recurring revenue churn calculations
- -Ignoring the distribution of churn - is it concentrated in a few large accounts or spread across many small ones?
Pro Tips
- +Target monthly revenue churn below 2% for SMB SaaS, below 1% for mid-market, and below 0.5% for enterprise
- +Implement dunning management (failed payment recovery) to reduce involuntary revenue churn by 20-40%
- +Analyze revenue churn by tenure - high early churn suggests onboarding problems, while later churn suggests value delivery gaps
- +Calculate the revenue churn dollar amount alongside the percentage to keep the financial impact tangible for your team
- +Compare revenue churn to logo churn: if revenue churn is much higher, you are losing your most valuable customers disproportionately

Gross Revenue Retention
Gross Revenue Retention (GRR) measures the percentage of recurring revenue retained from existing customers, excluding any expansion revenue. It isolates the impact of downgrades and churn on your revenue base.
Logo Churn
The percentage of customer accounts (logos) lost in a given period, regardless of the revenue each account represented.
Dollar Churn
The percentage of recurring revenue lost from cancellations and downgrades in a given period. Measures the financial impact of customer losses.
