PUTTING IT INTO PRACTICE
Annual Inventory Holding Cost: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Average inventory units | 500 |
| Unit inventory value | 20 |
| Annual carrying cost rate (%) | 25 |
| Result | 2,500 per year |
- Check the input labels and enter the example values above.
- Apply the relationship: Annual carrying cost = average units × unit value × carrying rate.
- The result is 2,500 per year, rounded for display.
How to interpret your result
The carrying rate must include only costs you intend to model and may vary by product.
Keep output and labour measures tied to the same period. Capacity is an assumption that may depend on staffing and process conditions. Average productivity and turnover can conceal seasonal peaks and bottlenecks.
Frequently asked questions
Does more output per hour always mean better performance?
Not by itself. Quality, rework, safety, cost and constraints can change the practical value of a productivity increase.
When is the annual inventory holding cost calculator useful?
Estimate the annual cost of carrying a chosen average stock balance. The carrying rate must include only costs you intend to model and may vary by product.
How do I use the annual inventory holding cost calculator?

Which formula does this calculator use?
Annual carrying cost = average units × unit value × carrying rate.
What should I check before using the result?
The carrying rate must include only costs you intend to model and may vary by product.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
