Revenue Churn Rate Calculator
Revenue churn rate (MRR churn) measures the percentage of your recurring revenue base that cancels or downgrades in a given period. For subscription and SaaS businesses, it is arguably the most important operational metric: even a small monthly churn rate compounds into major revenue loss over time. A 3% monthly revenue churn means roughly one-third of your revenue base disappears every year, requiring constant new growth just to stay flat. Enter your starting MRR and the MRR lost to cancellations and downgrades to calculate your churn rate and see annualized revenue loss.
Revenue churn rate formula
Revenue Churn Rate = Lost MRR / Starting MRR * 100 Annualized MRR Loss = Lost MRR * 12
Note: Annualized loss is a simple projection assuming constant churn. In practice, as your base grows or shrinks, the absolute dollar loss changes. Annual revenue churn rate = 1 - (1 - monthly rate)^12.
Understanding churn benchmarks
- Monthly revenue churn below 1%: world-class, typical of enterprise SaaS with annual contracts.
- 1 to 2%: strong, indicates good product-market fit and retention programs.
- 2 to 5%: acceptable for high-growth startups but requires monitoring.
- Above 5%: requires urgent attention. At 5% monthly churn, a business loses 46% of starting MRR in 12 months.
Revenue churn: frequently asked questions
What is revenue churn rate?
Revenue churn rate (also called MRR churn rate) is the percentage of monthly recurring revenue lost to cancellations and downgrades in a given period. It is calculated as lost MRR divided by starting MRR. A 2% monthly revenue churn means you lose 2% of your starting revenue base each month.
What is the difference between revenue churn and customer churn?
Customer churn measures the number of customers lost. Revenue churn measures the dollar value lost. Revenue churn is more actionable because it weights the loss by customer value: losing one $1,000 per month customer is worse than losing five $50 per month customers, which customer churn alone would not show.
What is a good monthly revenue churn rate?
For SaaS businesses, monthly revenue churn below 1% is excellent. 2 to 3% is acceptable for early-stage companies. Above 5% monthly churn is dangerous: at 5% monthly churn, you lose roughly half your revenue base in about one year.
What is negative revenue churn?
Negative revenue churn occurs when revenue from expansions (upgrades and upsells from existing customers) exceeds revenue lost from cancellations and downgrades. This is considered a strong indicator of product-market fit and sustainable growth.
How does revenue churn affect company valuation?
Revenue churn directly impacts Net Revenue Retention (NRR), a key SaaS valuation metric. Companies with NRR above 120% (negative churn) command significantly higher revenue multiples than those with NRR below 100% (positive churn), reflecting the compounding effect of revenue expansion from existing customers.
