Excess & Obsolete (E&O) Reserve benchmark
Excess & Obsolete (E&O) Reserve Benchmark for MRO Distribution (2026)
Last updated September 2026
The short answer
In mro distribution, excess & obsolete (e&o) reserve typically runs 15–25% — above the cross-industry band of 5–15% of inventory. Service buffers inflate E&O; active disposition pulls it down.
Formula
E&O Reserve = Σ (at-risk inventory value × age/consumption risk factor) MRO against the cross-industry band
| Industry | Typical E&O reserve | What good looks like |
|---|---|---|
| All industrial distribution | 5–15% of inventory | Disciplined operations hold E&O under 7% |
| MRO Distribution | 15–25% | Service buffers inflate E&O; active disposition pulls it down |
Lower is better on this metric. Every other industry benchmarked for E&O reserve is in the full benchmark table.
What excess & obsolete (e&o) reserve measures
The excess and obsolete (E&O) reserve is the share of inventory value written down because it is unlikely to sell. In industrial and MRO operations, 15–25% of stock is commonly excess or obsolete.
