Monthly Logo Churn
The percentage of customers (logos) lost in a month, calculated as churned logos divided by starting logos.

What it measures
The count of unique customer logos that cancelled or stopped paying in a calendar month as a share of logos active on the first day of that month. Downgrades (plan reductions that keep revenue flowing) are excluded; only full account terminations count as churn. Free-trial users who never paid are not counted as logos and do not contribute to churn.
Why it matters
Logo churn reveals how fast your customer base is shrinking. A 3% monthly churn means you lose ~35% of your base annually unless you add new customers faster than you're losing them. Leadership uses churn to answer 'Is our retention strong enough to grow?' Sales and product use it to prioritize retention features and customer success handoff quality. Finance uses it to forecast revenue stability; rising churn is often the first signal that product-market fit is slipping or that a key segment is dissatisfied. Unlike revenue churn, logo churn counts all customers equally—it's a proxy for satisfaction and product stickiness across your entire base.
How to read it
Low monthly churn (1–2%) means your product is sticky and your customer success team is effective. High monthly churn (5%+) doesn't mean the product is bad—it may signal wrong customer segment, pricing misalignment, poor onboarding, or inadequate support. Always read the trend: churn rising month-over-month is a red flag (accelerating decay); churn falling is green (improving retention). Segment by cohort, deal size, and region: losing a $10K/month customer feels the same as losing a $1K/month customer in logo churn, but revenue impact is 10× different. Compare current churn to historical cohorts to understand whether retention is improving.
What good looks like
Good
Monthly logo churn is under 2–3%, indicating strong product-market fit and customer satisfaction; annualized retention above 70%.
Watch
Monthly logo churn is 3–5%; investigate why customers are leaving and strengthen customer success and retention initiatives.
Bad
Monthly logo churn exceeds 5% (40%+ annual retention); churn is a critical issue requiring immediate product and go-to-market intervention.
Watch-outs
- Counting downgrades as churn. A customer moving from a $5K/month plan to a $2K/month plan is a downgrade or contraction, not churn. Only full account terminations (revenue to $0) count as churn. Downgrades are captured separately in Net Revenue Retention (NRR).
- Including free-trial or freemium churn. Free-trial users who never convert are not logos; freemium users on the free tier who downgrade to zero are not logos. Churn only applies to paying customers who cancel. This is critical: inflating churn with free users masks real retention health.
- Aggregating churn across divergent cohorts without segmentation. A 3% churn rate across SMB (small $1K/month deals), mid-market ($10–50K/month), and enterprise ($100K+ deals) hides the real picture. Enterprise churn of 8% and SMB churn of 1% both average to 3% but signal very different product-market fit. Always segment and track separately.
- Forgetting to annualize for strategic decisions. A 3% monthly churn doesn't mean 36% annual (3% × 12). It means you retain 97% each month, so annualized retention is 0.97^12 ≈ 71%—meaning 29% annual churn. Use the annualized figure for board forecasts and strategic planning; monthly churn is operational.
Worked example
Hypothetical
You start January with 500 paying customers. By month-end, 12 cancel. Your Monthly Logo Churn for January is 12 ÷ 500 = 2.4%. In February, you start with 488 (500 − 12). If 10 churn in February, your February churn is 10 ÷ 488 ≈ 2.05%. If this trend continues (assuming no new additions), you'd retain 97.6% each month; annualized, that's approximately 71% retention (29% annual churn).
