Churn Rate

Churn rate measures the percentage of customers (logo churn) or revenue (revenue churn) lost during a given period — typically monthly or annually. Customer churn rate is calculated as: customers lost ÷ customers at the start of the period. Revenue churn is calculated as: revenue lost from churned and downgraded customers ÷ revenue at the start of the period. These two numbers can diverge significantly: if small customers churn but large customers expand, revenue churn may be low or even negative while customer churn is high. Both numbers matter — customer churn indicates product-market fit issues; revenue churn determines the financial health of the business.

Churn is the silent tax on every growth investment. A business growing new ARR at 50% annually but churning 25% of existing ARR per year is effectively running a leaky bucket — spending heavily to fill the top while losing a quarter of its accumulated value from the bottom. The rule of thumb is that sustainable SaaS businesses maintain annual revenue churn below 5-7% for SMB and below 3% for enterprise. Below those thresholds, growth compounds. Above them, the business must run increasingly fast on the acquisition treadmill just to stay even.

For B2B content and video teams, churn rate is the metric that elevates customer success content from a nice-to-have to a strategic priority. Customers who successfully onboard, reach activation milestones, and understand how to extract maximum value from a product churn at dramatically lower rates than those who struggle silently. Video content — onboarding tutorials, feature deep-dives, use case walkthroughs, and customer success stories — directly addresses the root causes of churn: lack of adoption, unclear value, and poor knowledge of advanced capabilities. Measuring whether customers who engage with educational video content churn at different rates than those who don't is a straightforward A/B analysis that most teams have the data to run.
