Benchmarks

Inventory & procurement benchmarks by industry

What good looks like — with the formula behind each number. Compare your operation against the range for your sector.

Days Sales of Inventory (DSI)

DSI = (Average Inventory ÷ Cost of Goods Sold) × 365
Industrial Distribution 60–120 days Oil & Gas Distribution 90–150+ days MRO Distribution 90–180+ days PVF Distribution 75–140 days Electrical Distribution 55–100 days Utilities & Power 90–180+ days Oilfield Services 100–200+ days Chemical & Process Manufacturing 80–160 days

Inventory Turnover Ratio (Turns)

Inventory Turns = Cost of Goods Sold ÷ Average Inventory
Industrial Distribution 3–5 turns Oil & Gas Distribution 2–4 turns MRO Distribution 2–4 turns Electrical Distribution 4–6 turns PVF Distribution 2–4 turns Utilities & Power 1.5–3 turns Oilfield Services 1.5–3 turns Mining 1.5–3 turns Chemical & Process Manufacturing 2–4 turns

Inventory Carrying Cost

Carrying Cost % = (Capital + Storage + Service + Risk costs) ÷ Average Inventory Value
MRO Distribution 25–35% / yr Oil & Gas Distribution 25–40% / yr Industrial Distribution 25–40% / yr Chemical & Process Manufacturing 25–35% / yr Electrical Distribution 22–32% / yr PVF Distribution 25–38% / yr Utilities & Power 25–40% / yr

Excess & Obsolete (E&O) Reserve (E&O reserve)

E&O Reserve = Σ (at-risk inventory value × age/consumption risk factor)
MRO Distribution 15–25% Oil & Gas Distribution 15–30%

Quote Turnaround Time

Quote Turnaround = Time(quote sent) − Time(RFQ received)
MRO Distribution 1–3 days

GMROI (GMROI)

GMROI = Gross Margin $ ÷ Average Inventory Cost
Industrial Distribution 1.8–3.0 MRO Distribution 1.5–2.5 Electrical Distribution 2.0–3.2 PVF Distribution 1.6–2.6 Oil & Gas Distribution 1.4–2.4

Fill Rate

Fill Rate = Units Shipped from Stock ÷ Units Ordered
MRO Distribution 90–97% Industrial Distribution 93–98% Electrical Distribution 94–99% Utilities & Power 95–99%+

Cash Conversion Cycle (CCC)

CCC = DSI + Days Sales Outstanding − Days Payable Outstanding
Industrial Distribution 55–95 days MRO Distribution 70–120 days Oil & Gas Distribution 80–140 days PVF Distribution 65–115 days
