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.

Definition
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.
Formula
GRR = (Starting ARR − Contraction − Churn) ÷ Starting ARR, on the cohort active at period start. Excludes expansion. Capped at 100% by definition. Per SMSB GRR standard.Why it matters
Isolates the "do customers stay and not shrink" signal from expansion noise. GRR is the true downside floor on retention — boards use it to spot product or onboarding deterioration that NRR can hide.
How to interpret
Per KBCM/Sapphire Private SaaS Company Survey 2024 (§ "Gross Dollar Retention"), private SaaS GRR medians typically sit in the high-80s to low-90s, with top-quartile in the mid-90s — distributions vary by ACV cohort and vintage, so pull the current edition. The NRR − GRR gap quantifies expansion contribution; a widening gap with declining GRR is a yellow flag (expansion masking churn). Trend it quarterly — a single-period drop with steady NRR usually means a one-off contraction; persistent decline with flat NRR is a product issue.
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
- Cohort = customers active at the start of the period (same cohort as NRR).
- Numerator: Starting ARR − Contraction − Churn. Expansion is excluded by definition.
- Capped at 100% — if a calculation produces > 100%, expansion is leaking in.
Exclusion rules
- Expansion ARR, cross-sell ARR, price increases — none of these enter GRR (that is exactly what distinguishes GRR from NRR).
- New-logo ARR (same exclusion as NRR).
Required inputs
- Customer-level ARR snapshot at period start (cohort identity).
- Customer-level ARR snapshot at period end for the same cohort.
- Classification of each per-customer change as contraction vs churn vs (excluded) expansion.
Data-source priority
- Same cohort-tracking source as NRR; the two metrics share inputs.
Edge cases
- Customer with both expansion and contraction in the period: zero out the expansion, keep the contraction.
- Customer renaming or re-keying: hold cohort identity by account, not by name.
Validation checks
- GRR ≤ 100% always; > 100% means expansion is being counted (recompute with strict exclusion).
- GRR ≤ NRR for the same cohort; the gap is the expansion contribution.
Common miscomputations
- Letting expansion in — produces GRR > 100%, which is definitionally impossible; the most common GRR error.
- Reporting GRR alone without NRR — boards always want the pair to see whether expansion is masking churn.
- Conflating GRR with logo retention — GRR is dollar-based; logo retention is count-based; they answer different questions.
- Using a different cohort base than NRR — the two must use the same starting cohort to make the gap meaningful.

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).
