TL;DR
Logo churn is the percentage of customers (logos) lost in a defined period, regardless of their contract value. It is the customer-count counterpart to revenue churn — a team that loses 5% of logos but only 1% of revenue is losing small accounts. For B2B SaaS, healthy annual logo churn is under 8% for enterprise, 8–15% for mid-market, and 15–30% for SMB. Logo churn diverging from revenue churn is one of the most actionable diagnostic signals.
What is logo churn?
Logo churn (also called customer churn, account churn, or customer-count churn) is the percentage of customers lost during a defined period, calculated as (lost customers) divided by (starting customer count). Each customer counts as one "logo" regardless of contract value — a $5K customer and a $500K customer count equally toward logo churn.
Logo churn pairs with gross revenue churn to describe retention from two angles. Logo churn shows how many customers are leaving; revenue churn shows how much revenue is leaving. The two metrics often diverge: a team with 6% logo churn and 1.5% revenue churn is mostly losing small customers, while a team with 2% logo churn and 5% revenue churn is losing high-value accounts.
Logo churn is most actionable as a customer-count signal at SMB and mid-market scale, where account counts are large enough for meaningful percentage analysis. At enterprise scale, where a single account departure can move the percentage materially, logo churn is more useful as a binary alert than as a trend metric.
Why logo churn matters for operators
The divergence between logo churn and revenue churn is the most diagnostic retention signal. When logo churn is materially higher than revenue churn, the team is losing small accounts — usually a self-serve activation, onboarding, or pricing problem. When revenue churn is higher than logo churn, the team is losing large accounts — usually a competitive displacement or customer-success problem at the high end.
Logo churn also drives customer-success capacity planning. A team supporting 800 customers with 12% annual logo churn loses ~96 customers a year — meaning customer success needs to handle that many save-attempt and offboarding cycles annually, plus capacity for renewal motions on the surviving 700+. The math determines CSM-to-customer ratios.
The deeper signal in logo churn is brand and word-of-mouth dynamics. Customers who churn often stay in the market and become competitive references — positive or negative depending on how they were treated. High logo churn creates a long tail of former customers whose collective opinion matters more than the metric itself suggests.
Logo churn formula
Logo Churn (%) = Lost Customers / Starting Customer Count × 100 Annual logo churn (compounded from monthly): Annual = 1 − (1 − monthly)^12 Example — mid-market SaaS: Starting customers (Feb 1): 240 Customers cancelled or non-renewed: 3 Monthly logo churn: 1.25% Annualised logo churn: 14.0% Compare with revenue churn (same month): Starting MRR: $880,000 Lost MRR: $10,000 Monthly revenue churn: 1.14% The difference between 1.25% logo churn and 1.14% revenue churn is small here — meaning the lost customers were near-average size. A team with 1.25% logo churn and 0.4% revenue churn would be losing customers materially smaller than the average — typically a long-tail SMB or activation problem, not a top-of-book problem.
Logo churn benchmarks by stage and segment
| Segment | Healthy annual logo churn | Top-quartile | Crisis threshold | Logo-vs-revenue divergence diagnosis |
|---|---|---|---|---|
| Enterprise B2B SaaS | <8% | <5% | >12% | Logo > revenue: small-account loss |
| Mid-market B2B SaaS | 8–15% | <8% | >20% | Track both — usually similar |
| SMB B2B SaaS | 15–30% | <15% | >40% | Logo >> revenue: activation problem |
| PLG self-serve | 30–60% | <25% | >80% | Track 30/60/90-day cohort retention |
| D2C subscription | 40–80% (annual) | <40% | >100% | First-month retention is the metric |
| Vertical mission-critical | <5% | <2% | >8% | Logo loss is rare — investigate each one |

Common mistakes when measuring logo churn
1. Reporting only logo churn without revenue churn. Logo churn alone misses the value dimension. A team with 12% logo churn and 1% revenue churn has a very different problem than a team with 12% logo churn and 8% revenue churn. Always report both side by side; the divergence is the diagnostic signal.
2. Aggregating logo churn across ACV bands. A 12% aggregate logo churn rate that is 25% on the smallest tier and 4% on the largest tier paints a misleading picture of the average customer experience. Segment by ACV band — the patterns are almost always materially different across segments.
3. Including paused or trial accounts in the logo count. Pause states and trial customers are not yet committed customers; counting them in logo-churn denominators inflates customer counts and produces misleading rates. Define the logo-count rule explicitly (typically: paid customer with active subscription).
4. Not adjusting for seasonality. Logo churn often spikes at fiscal year-end (December for calendar-year customers, April for UK/Indian fiscal year) and at platform-renewal anniversaries. Compare year-over-year, same-quarter to same-quarter, not month-to-month.
5. Using customer-count as the headline at enterprise scale. A company with 35 enterprise customers losing 2 in a quarter has a 5.7% logo churn — but with such a small denominator, the percentage is volatile and misleading. At enterprise scale, logo churn is more useful as a binary alert ('a logo was lost') than as a trend percentage.
How Fairview tracks logo churn automatically
Fairview's Operating Dashboard tracks logo churn alongside revenue churn, segmented by ACV band, tenure cohort, ICP, and acquisition source — so divergence between the two metrics surfaces immediately as a diagnostic signal.
The Next-Best Action Engine flags structural divergence: "Q3 logo churn ran 3.4% (annualised 34%) while revenue churn was 0.9% (annualised 10%). The 24-percentage-point divergence concentrated in the SMB segment with sub-$5K ACV accounts. Recommend reviewing 30-day activation rates for SMB cohorts before the next renewal window."
Logo churn vs revenue churn vs dollar churn
Dollar churn is the absolute-dollar version of revenue churn; logo churn is the customer-count cut. Together with gross + net revenue churn, they describe retention from every angle.
| Logo churn | Revenue churn | Dollar churn | |
|---|---|---|---|
| Unit | Customer count | % of MRR | $ of MRR |
| Best for | Customer-count diagnostics | Aggregate retention rate | Absolute dollar tracking |
| Weights customers | Equally | By revenue | By revenue |
| When to use | SMB / activation analysis | Standard reporting | Cohort-level deep dives |

Frequently asked questions
What is logo churn in simple terms?
Logo churn is the percentage of customers (logos) that cancel or fail to renew in a period — counted by customer count, not by dollar value. A team with 200 customers that loses 6 in a quarter has 3% quarterly logo churn. The metric pairs with revenue churn; divergence between them is one of the most actionable retention diagnostics.
How is logo churn different from revenue churn?
Logo churn counts customers; revenue churn counts dollars. They diverge when account values vary widely. A 12% logo churn rate with 1% revenue churn means the team is losing small accounts. A 2% logo churn rate with 5% revenue churn means the team is losing large accounts. Each pattern has a different remedy.
What's a healthy annual logo churn rate?
Segment-dependent. Enterprise B2B SaaS: under 8%. Mid-market: 8–15%. SMB: 15–30%. PLG self-serve: 30–60% (much higher because trial-to-paid attrition is structural). D2C subscription: 40–80% annual is typical. Compare against motion-specific benchmarks; aggregate targets without segment context produce wrong conclusions.
Should you track logo churn or revenue churn as the headline?
Both. Revenue churn is the standard SaaS retention headline because it ties directly to revenue plan and valuation. Logo churn is the diagnostic complement that exposes which customer segments are leaving. Reporting only one obscures the structural information that the divergence between them carries.
How do you calculate annualised logo churn?
Use compounding: 1 − (1 − monthly)^12. A 2% monthly logo churn rate annualises to 21.5%, not 24%. The error grows at higher churn rates — at 5% monthly, simple multiplication gives 60% annual but compounded annual is actually 46.0%, a meaningful difference. Always use the compounding formula for annualised reporting.

Siddharth Gangal is the founder of Fairview. He built the logo-vs-revenue-churn view after watching a SaaS company report healthy 4% revenue churn for three quarters while logo churn ran 22% — meaning the company was losing small customers in volume and the long-tail brand damage compounded silently before anyone noticed.
