Enter your cost of goods sold and inventory values to calculate your turnover ratio, days inventory outstanding, and see how you compare to industry benchmarks for your distribution category.
These ranges reflect typical inventory turnover for healthy operations in each distribution segment. Use them as a reference point, not an absolute target. Your ideal turnover depends on your product mix, supplier lead times, and customer service requirements.
| Category | Healthy Range | Typical Days |
|---|---|---|
| Food & Beverage | 12 – 24 turns | 15 – 30 days |
| Bakery | 20 – 50 turns | 7 – 18 days |
| Hardware & Tools | 4 – 8 turns | 45 – 90 days |
| HVAC & Plumbing | 4 – 6 turns | 60 – 90 days |

Inventory turnover measures how many times a distributor sells and replaces its inventory during a given period, usually one year. It is one of the most direct indicators of operational efficiency in distribution.
The formula is straightforward:
Inventory Turnover Ratio = Cost of Goods Sold / Average Inventory
Average inventory is calculated as (Beginning Inventory + Ending Inventory) / 2. Days inventory outstanding is the inverse: 365 / Turnover Ratio, which tells you how many days, on average, your inventory sits before it is sold.
A higher turnover ratio generally means your capital is not tied up in slow-moving stock. A lower ratio can signal overstocking, dead inventory, or weak demand. However, turnover that is too high may indicate that you are understocking and risking stockouts, which costs you orders and customer trust.
