Churned ARR
Definition
Annualized recurring revenue lost during the period from customers who fully cancelled — terminating their contract or letting it lapse without renewal. The "leak" line of the ARR waterfall and the denominator of Gross Revenue Retention. Distinct from Downgrade ARR (sales.downgrades) which captures contractions where the customer stays. Common pitfall: lumping mid-term cancellations with non-renewals masks two very different retention failures — surface them separately when material. The KpiVarianceTable widget tracks period forecast vs actual; a widening miss against forecast is the earliest signal of a retention problem.
Why it matters
Direct read on Gross Revenue Retention (GRR) — the floor of the retention math, since downgrades and churn cannot be offset by upsell in GRR. A board can tolerate slow new-logo growth if churn is low, but cannot tolerate high churn at any growth rate — it compounds against valuation.
How it's calculated
Churned ARR = Sum of ARR from contracts that terminated during the period (cancelled mid-term or not renewed at the end of term) attributable to customers whose ARR with the company drops to zero. Excludes contractions where the customer remains (those land in Downgrade ARR). How to interpret it
Per KBCM/Sapphire SaaS Survey 2024 §Gross Revenue Retention, top-quartile SaaS companies hold GRR ≥ 90% (enterprise-segment) or ≥ 85% (SMB-segment); GRR below 80% in either segment usually means the product or onboarding has a structural problem, not a sales-execution one. Pair this line with the Customers domain to identify whether churn concentrates in a particular segment or cohort.

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.
Annualized recurring revenue lost from existing customers who reduced spend mid-term or at renewal (seat reductions, tier downgrades, removed modules) — without leaving entirely. The "contraction" line of the ARR waterfall, distinct from full churn. Often a more sensitive leading indicator than churn because customers tend to contract before they cancel. Common pitfall: lumping downgrades into churn obscures the early-warning signal — boards looking only at logo churn miss the slow-bleed pattern. Surfaces in the KpiVarianceTable widget alongside expansion and churn so the net-retention math is auditable.
Annualized recurring revenue added during the period from existing customers — through upsell (more seats / higher tier), cross-sell (additional products), or price increases. The "farm" line of the ARR waterfall. Boards read this as the leading indicator that product-market fit has translated into product-account fit and that the post-sale motion is creating compound growth. Common pitfall: classifying contractual price-step-ups (CPI escalators baked into the original contract) as expansion overstates new selling motion. Expansion CAC Ratio and Net Revenue Retention are derived from this number.
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.
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.
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.
