4 is the example result. Read it using the units and relationship stated below.
Compare COGS (cost of goods sold) with average inventory to estimate how often the inventory value turns over in the period.
Read movement without losing availability
The ratio uses inventory at cost, not retail selling value. Average inventory should represent the period rather than one unusually high or low closing balance.
When to use this result
Use turnover during a stock review. Look at stockouts and slow-moving items alongside the aggregate ratio; a higher turnover can reflect efficient purchasing or insufficient stock.
Check before you act
Compare periods of equal length. Seasonal demand and a change in product mix can make a whole-business ratio difficult to interpret.
Example with the supplied inputs
COGS: 300000; Average inventory: 75000. Result: 4. The values are illustrative.
Compare one changed input
COGS changes from 300000 to 330000. The result becomes 4.4. All other inputs remain fixed.
Calculation rule
Result = (([COGS]) ÷ ([Average inventory]))
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| COGS | 300000 | Use the source quantity represented by cogs. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Average inventory | 75000 | Use the source quantity represented by average inventory. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 4 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather COGS, Average inventory. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change COGS on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 4.
Change COGS from 300000 to 330000 while keeping every other value fixed. The result becomes 4.4. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
