Product managers and founders constantly monitor churn to gauge the health of their subscription businesses. Churn rate is a fundamental health metric that measures the rate at which customers cancel their subscriptions or recurring revenue is lost over a given time period. High churn directly stifles growth—no matter how many new customers you acquire, a leaky bucket means you will eventually hit a growth ceiling.
Customer Churn vs Revenue Churn: What's the Difference?
There are two primary ways to measure churn in a SaaS business, and understanding both is critical for evaluating product-market fit.
- Customer Churn (Logo Churn): The percentage of individual customers or accounts that canceled. E.g., if you start the month with 100 customers and lose 5, your customer churn is 5%. This metric is most valuable for B2C apps and SMB-focused SaaS with flat pricing.
- MRR Churn (Revenue Churn): The percentage of Monthly Recurring Revenue lost due to cancellations, downgrades, or paused accounts. This is critical for B2B SaaS, as not all customers pay the same amount. Losing one $10,000/mo enterprise client hurts more than losing fifty $20/mo startups.
Gross Revenue Retention (GRR) vs Net Revenue Retention (NRR): Your MRR churn contributes directly to GRR (which maxes out at 100%). However, if you upsell existing customers, you can achieve an NRR above 100%, indicating that account expansion is completely offsetting the revenue lost to churn.
SaaS Churn Rate Benchmarks: What's a Good Churn Rate in 2026?
"What is a good SaaS churn rate?" is one of the most common questions PMs ask. The truth is, benchmarks wildly vary by audience tier. Based on 2026 SaaS industry data, here are the average monthly churn rates you should aim for:
Consumer SaaS (B2C)
5% - 7%
Monthly churn. High volume, high turnover is typical.SMB SaaS (B2B)
3% - 5%
Monthly churn. Startups fail, driving involuntary churn.Enterprise SaaS
< 1%
Monthly churn. Sticky contracts lock in revenue long-term.Churn Rate Examples: How to Calculate
Let's look at a few examples of how to correctly measure and calculate churn rate across different scenarios.
Example 1: Early-Stage Startup (Customer Churn)
- Starting Customers (March 1): 500
- Customers Lost Over March: 25
- Calculation: (25 / 500) × 100
- Monthly Customer Churn Rate = 5%
Example 2: Growth SaaS (Revenue Churn)
- Starting MRR (April 1): $100,000
- Downgrades & Cancellations: $3,000
- Calculation: ($3,000 / $100,000) × 100
- Monthly MRR Churn Rate = 3%
How to Convert Monthly Churn to Annual Churn
Many teams mistakenly multiply their monthly churn rate by 12 to find their annual churn. Because compounding exists, this is mathematically incorrect. If you lose 5% of your customer base every single month, you don't lose 60% annually—you lose about 46% (because the total base shrinks each month). Use this correct formula:
Annual Churn ≈ 1 - (1 - Monthly Churn)¹²
Frequently Asked Questions
What is a good churn rate?
A "good" churn rate highly depends on your customer base. For Enterprise SaaS, a good monthly churn rate is under 1%. For SMB SaaS, 3-5% monthly is typical. Anything above 5% monthly usually indicates a product-market fit issue or poor onboarding.How is MRR churn different from customer churn?
Customer churn (logo churn) measures the percentage of customers who cancel. MRR churn (Revenue churn) measures the percentage of monthly recurring revenue lost. You can have low customer churn but high MRR churn if your largest enterprise customers leave.How do I reduce churn?
Start by tracking why users leave (exit surveys). Improve onboarding so users reach "aha" moments faster. Identify at-risk users by tracking activity drop-offs, and proactively reach out. Finally, ensure your pricing scales with the value users get so they don't downgrade unnecessarily.What is net revenue retention (NRR)?
While gross churn only looks at money lost to cancellations and downgrades, Net Revenue Retention (NRR) also includes expansion revenue (upsells). An NRR above 100% means your growth from existing customers outpaces the revenue lost from churned customers.How does churn affect valuation?
High churn destroys LTV (Lifetime Value) and makes it incredibly expensive to grow, as you have to constantly replace lost revenue. Investors heavily penalize SaaS companies with high churn. A difference of just 2% in monthly churn can halve the valuation of a SaaS startup.Ready to calculate your churn?
