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).

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

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.

Formula

Closed-Lost Value = Σ (deal_value) across opportunities that transitioned to closed-lost in the period. Use the same value convention (TCV vs ACV) as Closed-Won Value for consistency.

Why it matters

Quantifies the realized opportunity cost — useful for justifying packaging changes, ICP refinement, or product investment that would have closed specific tier-1 losses. Drives loss-reason prioritization.

How to interpret

Loss-Value / Won-Value (= loss share of total close events) — at steady state usually 30–60% depending on motion type (inbound-heavy motions have higher win rates and lower loss values; outbound motions have lower win rates and higher loss values). Spiking loss-value with stable won-value usually indicates competitive friction or pricing pressure on enterprise deals specifically.
