% 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. — Customers KPI, I'mBoard-authored (editorial tier).

No public third-party standard anchors this KPI yet, so I'mBoard authors and maintains the definition — transparently labeled as editorial tier. See the ontology methodology for the published vs editorial tier system and the back-attribution workstream.

Definition

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.

Formula

percent_arr_at_risk = arr_at_risk ÷ total ARR. The numerator inherits the company-specific "at-risk" flag definition documented on `customers.arr_at_risk`.

Why it matters

Normalizes the at-risk dollar figure so it scales with the business. A 10% at-risk share is the same proportional threat at $5M ARR as at $50M ARR; the absolute figure alone hides that.

How to interpret

No citation-grade industry benchmark; widely-cited industry folk-wisdom (not citation-grade) flags >15% percent_arr_at_risk as a destructive threshold worth board escalation — the ArrAtRiskGauge widget uses this internally. Trend it month-over-month — sustained growth in this share predicts a downward NRR move next quarter even if no single account has churned yet.
