Understanding Customer Churn
What it does
Calculates your customer churn rate for a given period, annualizes it, projects yearly customer loss and revenue impact based on average customer MRR.
Why it matters
Churn is the silent revenue killer. A 5% monthly churn erodes 46% of your customer base annually. Reducing churn by just 2% can double company lifetime value.
Definition
Churn Rate = (Customers Lost / Starting Customers) × 100. Annualized rate compounds monthly/quarterly rate across 12 months.
Assumptions
- •Customer loss is net of all churn reasons (competitive loss, downgrades, non-renewal).
- •Average MRR per customer is constant (doesn't account for upsells or downgrades).
How to interpret your results
SaaS benchmarks: <5% annual churn = excellent, 5-10% = good, 10-25% = needs work, >25% = critical. Even 1% improvement can be worth millions.
How to improve
Improve onboarding
Customers who see value in the first 30 days rarely churn. Systematic onboarding is the #1 retention lever.
Proactive support
Reach out to at-risk customers before they cancel. Health scoring and engagement tracking prevent surprise churn.
Product evolution
Gather churn feedback and prioritize feature requests that directly prevent churn.
