Understanding Inventory Turnover
Inventory turnover measures how many times a company sells and replaces its inventory over a given period. It's a key indicator of inventory management efficiency, showing how well a business manages its stock levels and converts inventory into sales.

Inventory Turnover Formulas
Key Calculations
How to calculate inventory turnover
Inventory Turnover Ratio:
- Turnover = COGS ÷ Average Inventory
- Shows how many times inventory is sold
- Higher ratio generally better
- Industry-specific benchmarks
Days Inventory Outstanding:
- DIO = (Average Inventory ÷ COGS) × Days in Period
- Days inventory sits before being sold
- Lower DIO generally better
- Cash conversion cycle component
Interpreting Turnover Ratios
High Turnover (Good):
- Efficient inventory management
- Lower carrying costs
- Fresh product availability
- Better cash flow
Low Turnover (Concerning):
- Excess inventory accumulation
- Higher carrying costs
- Potential obsolescence
- Cash tied up in inventory
Industry Benchmarks
| Industry | Average Turnover | Average DIO | Key Factors |
|---|---|---|---|
| Grocery Retail | 12-16x | 23-30 days | Perishable goods |
| Electronics | 6-10x | 36-60 days | Product lifecycle |
| Automotive | 4-6x | 60-90 days | High-value inventory |
| Fashion Retail | 4-8x | 45-90 days | Seasonal demand |
Improving Inventory Turnover
Demand Forecasting:
