There is no universal "good" inventory turnover ratio. A jewelry store operating at 2× turnover might be perfectly healthy; a grocery store at 2× would be in serious trouble. The benchmark depends entirely on your industry's economics.
How to read inventory benchmarks
Higher turnover is not always better. Very high turnover can signal: - Stockouts: selling out before restocking, losing sales - Understocking: carrying too little buffer for demand spikes - Under-investment in inventory leading to missed revenue
Optimal turnover balances: - Carrying costs (warehouse, insurance, obsolescence) — minimized by higher turnover - Stockout costs (lost sales, lost customers) — minimized by lower turnover - Cash flow requirements — improved by higher turnover
Benchmarks by industry
Grocery and food/beverage: 20–30× turnover, 12–18 days DSI Perishables must move fast. Grocery chains optimize store-level inventory daily. Dead stock is often donated or disposed of; waste is tracked as a KPI.
Fast fashion and apparel: 6–12× turnover, 30–60 days DSI Trend-driven demand makes forecasting hard. Fast fashion brands like Zara have redesigned supply chains to achieve 12×+ by manufacturing closer to season.
Consumer electronics: 6–10× turnover, 37–61 days DSI High obsolescence risk (new model releases, price erosion) creates pressure to turn inventory quickly. Distributor and retailer margins are thin.
Automotive parts: 4–8× turnover, 46–91 days DSI Wide SKU counts and long-tail demand make this complex. Auto parts retailers typically carry 50,000–100,000+ SKUs.
Furniture and home goods: 3–6× turnover, 61–122 days DSI Large items, high logistics cost, longer purchase cycles. Custom furniture may have even lower turnover by design (made-to-order).
Industrial and B2B products: 2–5× turnover, 73–183 days DSI MRO (maintenance, repair, operations) items may be held for years as insurance against downtime. Business continuity value exceeds carrying cost.
Pharmaceuticals: 3–4× turnover, 90–120 days DSI Expiration dates create carrying risk. Regulatory requirements add complexity.
How to benchmark yourself
- Calculate your annual inventory turnover and DSI.
- Find your industry's median from trade associations or public company reports.
- Identify whether you're in the top quartile, median, or bottom quartile.
- Set a target to improve turnover by 1–2× within 12 months.
For e-commerce businesses: aim for the top quartile of your category. Every 1× improvement in turnover at $500k average inventory frees ~$83k in cash.
