Logo Churn Rate
Share of customer logos lost during the period — the inverse of logo retention. Numerator is logos that churned during the period; denominator is logos present at period start. Per the KBCM/Sapphire Private SaaS Company Survey definition (treated as the de-facto private-SaaS reporting convention). The board reads this as the simplest churn signal — independent of revenue-weighting. Common pitfall: confusing annualized vs. period-rate (monthly churn × 12 ≠ annualized churn for a compounding base) — be explicit about the time window and annualization method. — Customers KPI anchored to KBCM/Sapphire SaaS Survey 2024 (15th Annual).

Definition
Share of customer logos lost during the period — the inverse of logo retention. Numerator is logos that churned during the period; denominator is logos present at period start. Per the KBCM/Sapphire Private SaaS Company Survey definition (treated as the de-facto private-SaaS reporting convention). The board reads this as the simplest churn signal — independent of revenue-weighting. Common pitfall: confusing annualized vs. period-rate (monthly churn × 12 ≠ annualized churn for a compounding base) — be explicit about the time window and annualization method.
Formula
logo_churn_rate = customers_churned ÷ (customers active at period start). Mathematically: 1 − logo_retention_rate. Annualization for monthly/quarterly rates should be explicit (e.g. (1 − monthly_retention)^12, not monthly_churn × 12).Why it matters
Direct read on whether customers are walking away. Independent of revenue-weighting, so it cannot be masked by a few large expansions.
How to interpret
Per KBCM/Sapphire Private SaaS Company Survey 2024 (§ "Customer Churn"), private SaaS logo churn typically sits in the high single digits annually, with top-quartile below 5% — but distributions are highly sensitive to ACV cohort (low-ACV SMB SaaS routinely sees 20%+ annual logo churn; six-figure enterprise contracts often see <3%). Pull the current vintage rather than citing a stale point estimate. Pair with customers_churned (absolute count) and gross_revenue_retention (revenue-weighted view).
Calculation policy
How an AI agent should compute this KPI from messy company data. Free-text rules consumed at reasoning time — not a deterministic DSL. The most common ways to get this wrong are listed under Common miscomputations.
Inclusion rules
- Numerator: count of logos that churned (fully left) during the period.
- Denominator: count of logos active at period start (the closed starting cohort).
- Result is a percentage; the exact complement of
customers.logo_retention_rate.
Exclusion rules
- Net-new logos acquired in-period — not in the denominator.
- Downgrades / contractions where the logo remains — this is a count-of-departures metric, not a revenue one.
- Trials / pilots that never converted.
Required inputs
- Count of churned logos in the period.
- Count of logos active at period start.
- Time window + annualization method (state explicitly).
Data-source priority
- Customer-level subscription ledger with churn events.
- CRM as a fallback.
Edge cases
- Annualizing a monthly or quarterly rate: use
1 − (1 − periodic_churn)^periods(geometric), NOTperiodic_churn × periods(arithmetic). The two diverge materially as churn rises. - Account merger: the absorbed logo is not churn — the relationship continued.
- Reactivation within the period: if the logo is active at period end, it is retained, not churned. Disclose if reactivations are material.
- ACV-cohort mixing: blended logo churn is misleading when SMB and enterprise are pooled — SMB routinely 20%+, enterprise <3%. Segment when material.
Validation checks
- Logo Churn Rate + Logo Retention Rate = 100% exactly.
- Bounded 0–100%.
- Churned-logo count ≤ starting-cohort count.
Common miscomputations
- Annualizing via
monthly_churn × 12instead of the geometric1 − (1 − monthly_retention)^12— overstates annual churn, badly so when churn is high. - Confusing logo churn with revenue churn — they diverge; logo churn cannot be masked by expansion, revenue churn can.
- Using period-end logo count as the denominator — the cohort must be fixed at period start.
- Counting account mergers or contractions as churn — only full departures count.
- Reporting a blended rate across wildly different ACV cohorts without segmenting — the blend is not actionable.

Gross Revenue Retention (GRR)
Recurring revenue retained from the cohort of customers present at the start of the period, excluding expansion — so the metric captures only churn and contraction. Per the SaaS Metrics Standards Board (SMSB) GRR standard. GRR is bounded at 100% (cannot exceed it) and reads as the "no-defense-against-churn" floor on retention. The board reads GRR alongside NRR (`customers.net_revenue_retention`) — the gap between them is the expansion contribution. Common pitfall: treating GRR and NRR as substitutes — they answer fundamentally different questions, and a healthy NRR with sliding GRR signals churn masked by upsell. — Customers KPI anchored to SaaS Metrics Standards Board.
Logo Retention Rate
Share of customer logos retained from the prior period, counted by logo (not by revenue). Per the SaaS Metrics Standards Board (SMSB) Logo Retention standard: numerator is logos present at both period start and period end; denominator is logos present at period start. New logos acquired during the period are excluded from both. The board reads this as a "stickiness" signal independent of ACV: high logo retention with weak NRR points to flat/contracting expansion; weak logo retention with strong NRR points to high concentration risk. Common pitfall: conflating logo retention with revenue retention — they answer different questions and routinely diverge. — Customers KPI anchored to SaaS Metrics Standards Board.
