Net Revenue Retention (NRR)
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.
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 it's calculated
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. How to interpret it
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.

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.
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.
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.
Identified upsell, cross-sell, and seat-expansion opportunities inside the existing customer base, with deal size and timing where known. This is the qualitative narrative behind the expansion component of NRR — what the CS / Sales team sees in the pipeline that has not yet converted. The board reads this as forward-looking signal on whether NRR will trend up or down next quarter. Common pitfall: confusing "opportunities" (real conversations with named accounts) with "addressable upside" (theoretical TAM uplift) — keep this field anchored in actual pipeline.
Annual Recurring Revenue — the value of all recurring subscription revenue normalized to a one-year run-rate as of the period close. The headline operating metric for a subscription business; every growth and efficiency ratio (NRR, GRR, magic number, CAC payback, Rule of 40) is calibrated against it. Excludes one-time fees, professional services, and non-contractual usage. Common pitfall: confusing ARR (contracted recurring) with revenue (recognized) or with CARR (contracted incl. not-yet-live) — the SMSB standard draws sharp lines between them, and boards expect the same discipline. The KpiVarianceTable widget surfaces forecast / actual / variance / status / future-forecast columns against the same field.
