Net Revenue Retention (NRR)
Recurring revenue retained from the cohort of customers present at the start of the period, including expansion (upsell, cross-sell, price increases) and net of churn and contraction — but excluding revenue from net-new logos acquired in-period. Per the SaaS Metrics Standards Board (SMSB) NRR standard. NRR above 100% means the cohort grew faster than it lost — a hallmark of strong product-led expansion. The board reads NRR alongside GRR (`customers.gross_revenue_retention`) to separate the "keep + expand" signal from the "just keep" signal. Common pitfall: mixing GAAP revenue and ARR in numerator vs. denominator, or letting net-new logo revenue leak in — both inflate the number; SMSB is explicit that the cohort is closed at period start. — Customers KPI anchored to SaaS Metrics Standards Board.

Definition
Recurring revenue retained from the cohort of customers present at the start of the period, including expansion (upsell, cross-sell, price increases) and net of churn and contraction — but excluding revenue from net-new logos acquired in-period. Per the SaaS Metrics Standards Board (SMSB) NRR standard. NRR above 100% means the cohort grew faster than it lost — a hallmark of strong product-led expansion. The board reads NRR alongside GRR (customers.gross_revenue_retention) to separate the "keep + expand" signal from the "just keep" signal. Common pitfall: mixing GAAP revenue and ARR in numerator vs. denominator, or letting net-new logo revenue leak in — both inflate the number; SMSB is explicit that the cohort is closed at period start.
Formula
NRR = (Starting ARR + Expansion − Contraction − Churn) ÷ Starting ARR, measured on the cohort active at period start. New-logo ARR acquired in-period is excluded from both numerator and denominator. Per SMSB NRR standard.Why it matters
The single best read on whether existing customers love the product enough to pay more over time. Strong NRR (>100%) compounds — it lets growth come from inside the install base, lowering reliance on new-logo acquisition and improving capital efficiency.
How to interpret
Per KBCM/Sapphire Private SaaS Company Survey 2024 (§ "Net Dollar Retention"), private SaaS NRR medians have historically clustered around the low-to-mid 100s, with top-quartile in the 110s+ — but cuts vary year-over-year and by ACV segment, so pull the current edition rather than citing a stale point estimate. Top-quartile public SaaS (per typical Bessemer State of the Cloud commentary) cite NRR ≥ ~120% as the benchmark for "best-in-class" expansion — treat that thresholds as industry folk-wisdom unless cited to a named edition. Always pair NRR with GRR: a wide gap means expansion is propping up underlying churn.

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.
NPS Score
Net Promoter Score — % of survey respondents who are promoters (score 9–10) minus % detractors (0–6), passives (7–8) excluded. Per the original NPS methodology (Reichheld, Bain & Company, 2003). The score ranges from −100 to +100. The board reads NPS as one read on product-market fit and word-of-mouth potential, not as a precise customer-loyalty measurement — the methodology is well-known for being sensitive to sample bias, response rate, and survey timing. Common pitfall: comparing NPS across companies without normalizing for industry — B2B SaaS NPS distributions sit much higher than consumer-app NPS, and the absolute number means little without a peer cohort. — Customers KPI anchored to Retently NPS Benchmarks 2025.
