ARR at Risk

Definition

Sum of ARR from customers flagged "at-risk" by the customer-success team — typically driven by usage decline, low health score, executive turnover at the customer, missed milestones, or explicit churn intent. The board reads this as the worst-case near-term churn exposure if no intervention happens. Common pitfall: the "at-risk" definition drifts across CSMs and quarters; standardize the criteria (e.g. health score below threshold OR 30-day usage drop > X% OR cancellation request received) and version-control the playbook so the absolute number is comparable period-over-period. Pair with `percent_arr_at_risk` for the proportional read.

Why it matters

Converts the qualitative CS pipeline into a board-readable dollar exposure. Forces the team to put a number on hand-wavy customer-health concerns and surfaces concentration risk (a single $500K at-risk account is a different conversation than fifty $10K accounts).

How it's calculated

arr_at_risk = Σ(ARR of customers flagged at-risk by CS team). The "at-risk" flag itself is a company-specific definition (typical components: health score below threshold, 30-day usage decline, executive churn at customer, missed onboarding milestones, explicit churn signal). Document the flag rule in `customer_definition_note` so the number is comparable across periods.

How to interpret it

Always present alongside `percent_arr_at_risk` — $500K at-risk is a 5% problem at $10M ARR but a 0.5% problem at $100M ARR. There is no citation-grade industry benchmark for the absolute number; the >15% destructive threshold the `ArrAtRiskGauge` widget uses is internal heuristic, not an external standard. Trend month-over-month — sustained growth in `arr_at_risk` is the leading indicator that NRR will deteriorate next quarter.

% ARR at Risk

Share of total ARR flagged as at-risk for churn or contraction — the proportional view that complements the absolute `arr_at_risk` dollar figure. Computed as `arr_at_risk ÷ total ARR`. The board reads this as the worst-case-near-term-NRR-impact ceiling: if every at-risk account actually churned in-period, NRR would drop by roughly this percentage (before expansion offset). Common pitfall: the "at-risk" definition is internal and varies by company — a 12% percent_arr_at_risk under a conservative flagging rule is a very different signal than 12% under an aggressive rule. Document the flag rule and hold it constant.

Churn Risks

Named at-risk accounts, root-cause analysis of why they're at risk, and the mitigation plan in flight. Pairs with the quantitative `arr_at_risk` and `percent_arr_at_risk` and gives the board the names + the playbook. Common pitfall: listing the at-risk accounts without the diagnosis or the plan — the board reader needs to see what the team is doing about it, not just what the team is worried about. Also: avoid using this surface as a generic "things are bad" venting forum — keep it account-specific and action-specific.

Top Customer Concentration

Share of total ARR contributed by the top N customers — typically top 5 or top 10. Measures revenue concentration risk: a high concentration means losing one big customer would materially dent ARR. The board reads this alongside `arr_at_risk` and the customer list to gauge how much of the company's future is tied to a handful of accounts. Common pitfall: hiding parent-account aggregation — if three "customers" are subsidiaries of the same parent, true concentration is higher than the count-by-logo view shows; settle parent-rollup rules and document them in `customer_definition_note`.

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.

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.

ARR

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.
