Inventory Turnover Formula and Inputs
Inventory turnover = cost of goods sold ÷ average inventory.
Business metrics are most useful when the inputs come from the same time period and the same definition. Before comparing results, decide whether you are measuring revenue, profit, customers, orders, units, leads, or another specific business event.
| Input | How to Use It |
|---|---|
| Cost of goods sold | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Beginning inventory | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Ending inventory | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Time period | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
Worked Inventory Turnover Example
If annual COGS is $240,000 and average inventory is $40,000, inventory turnover is 6 times per year.
After calculating one result, change one input at a time. This makes it easier to see whether price, cost, volume, conversion rate, retention, ad spend, or labor is driving the business outcome.
How to Interpret the Result
Higher turnover can mean efficient inventory use, but extremely high turnover may also signal stockouts or missed sales.
A business calculator can point you toward better decisions, but the number should be reviewed with context: margin, cash timing, customer quality, seasonality, capacity, and whether the result can repeat.
Common Inventory Turnover Mistakes
- Using sales revenue instead of COGS.
- Using ending inventory instead of average inventory.
- Ignoring seasonality.
- Comparing unlike industries.
