Days Sales of Inventory benchmark
Days Sales of Inventory Benchmark for MRO Distribution (2026)
Last updated September 2026
In mro distribution, days sales of inventory typically runs 90–180+ days — above the cross-industry band of 61–90 days. Service buffers inflate DSI; watch the slow-mover tail.
DSI = (Average Inventory ÷ Cost of Goods Sold) × 365 MRO against the cross-industry band
| Industry | Typical DSI | What good looks like |
|---|---|---|
| All industrial distribution | 61–90 days | Under 60 days is strong for wholesale distribution |
| MRO Distribution | 90–180+ days | Service buffers inflate DSI; watch the slow-mover tail |
Lower is better on this metric. Every other industry benchmarked for DSI is in the full benchmark table.
What days sales of inventory measures
Days sales of inventory (DSI) measures how many days it takes to sell the average inventory on hand. Lower is better — it means cash cycles back faster.
The sectors landing closest to MRO on this metric are Utilities & Power. A sector further away is not doing better or worse by definition — the band reflects what the work requires, which is why the comparison that matters is against your own history as much as against the industry.
