Deals Lost
Count of opportunities that transitioned to closed-lost during the period — the volume side of pipeline disqualification. The other half of the win rate denominator; without tracking it explicitly you cannot compute or benchmark win rate. Common pitfall: stale "open" deals that should be marked lost are left open, inflating pipeline value while suppressing the lost count — a hygiene problem that compounds because next-period coverage looks fine while win rates silently degrade. Every CRM hygiene policy should specify a max-age before deals auto-flag for lost-or-update review. — Sales KPI, I'mBoard-authored (editorial tier).

Definition
Count of opportunities that transitioned to closed-lost during the period — the volume side of pipeline disqualification. The other half of the win rate denominator; without tracking it explicitly you cannot compute or benchmark win rate. Common pitfall: stale "open" deals that should be marked lost are left open, inflating pipeline value while suppressing the lost count — a hygiene problem that compounds because next-period coverage looks fine while win rates silently degrade. Every CRM hygiene policy should specify a max-age before deals auto-flag for lost-or-update review.
Formula
Closed-Lost Count = Count of distinct opportunities whose stage transitioned to closed-lost during the period. Excludes "no decision" / paused opportunities (which should have a separate stage); excludes disqualified-pre-pipeline opportunities.Why it matters
Denominator input for win rate and direct read on pipeline hygiene. Cluster analysis of loss reasons feeds product / pricing / positioning decisions that boards expect to see referenced in strategic_context.
How to interpret
Track loss-reason distribution quarter-over-quarter — concentration in "price" usually points to packaging; concentration in "feature gap" feeds product roadmap; concentration in "no decision" usually means lead-qualification is too loose. Pair count with value to spot mix-shift (e.g. losing more small deals while winning the large ones is a different motion problem than the inverse).

Churned ARR
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. — Sales KPI, I'mBoard-authored (editorial tier).
Deals Lost Value
Total dollar value of opportunities closed-lost during the period — the opportunity-cost view on the pipeline motion. Useful for sizing the "what we missed" gap and prioritizing post-mortem efforts on the highest-value losses. Common pitfall: post-mortems on small lost deals waste time relative to insight; tier the post-mortem cadence by value (e.g. every loss above the 80th-percentile deal size gets a written debrief). Boards expect the largest 2–3 losses to be explained explicitly in commentary. — Sales KPI, I'mBoard-authored (editorial tier).
