How much does holding inventory cost?
Inventory carrying cost estimates the annual burden of holding stock. Multiply average inventory value by an annual carrying rate, or total capital, storage, insurance, shrinkage, obsolescence and administration costs. The monthly figure is the annual estimate divided by twelve.

The formula, explained.
Simple annual cost = average inventory × annual carrying rate Detailed annual cost = capital + storage + insurance + shrinkage + obsolescence + administration Carrying rate = annual cost ÷ average inventory
A worked example
- Suppose your business holds $50,000 of inventory on average, measured at cost rather than selling price. In simple mode, use an annual carrying rate of 25%. Multiplying $50,000 by 0.25 gives an estimated annual carrying cost of $12,500. Dividing by twelve gives $1,041.67 per month, though actual cash spending may be uneven during the year.
- In detailed mode, enter annual amounts instead of the percentage shortcut. For example, $5,000 capital cost, $4,000 storage, $1,000 insurance and taxes, $500 shrinkage, $1,000 obsolescence and $1,000 administration total $12,500. Dividing that total by $50,000 average inventory reproduces the 25% carrying rate. Do not also add the purchase value of the inventory itself.
- If average inventory falls to $40,000 while the effective rate remains 25%, the simple estimate falls to $10,000 per year: a $2,500 saving. Treat that as a scenario, because warehouse rent or staffing might not decrease proportionally. Compare avoidable carrying costs with any extra ordering, freight and stockout costs caused by buying smaller batches before changing your replenishment policy.
How to interpret your result
The carrying rate translates inventory on your balance sheet into an annual operating burden. Compare the savings from smaller orders against extra ordering and freight costs.
Common mistakes to avoid
Enter annual costs in detailed mode. Do not add the inventory purchase value itself as a carrying cost, and avoid counting warehouse labor twice.
Frequently asked questions
How much does holding inventory cost?
Average inventory of $50,000 at a 25% carrying rate costs $12,500 per year, or $1,041.67 per month. The carrying rate translates inventory on your balance sheet into an annual operating burden. Compare the savings from smaller orders against extra ordering and freight costs.
What percentage of inventory value should carrying cost be?
Commonly cited ranges put annual carrying cost at roughly 15% to 30% of inventory value, with the lower end associated with tighter inventory control and the higher end with less efficient handling. There is no fixed target; use your own capital cost, storage, insurance, shrinkage and obsolescence figures rather than a borrowed percentage.
What is included in inventory carrying cost?
Carrying cost typically includes the cost of capital tied up in inventory, physical storage and warehousing, insurance and taxes, shrinkage (loss, theft, damage), obsolescence, and the administration or handling required to manage the stock. The purchase cost of the inventory itself is not a carrying cost; carrying cost is the ongoing burden of holding inventory you have already bought.
Is carrying cost the same as holding cost?
Yes. "Carrying cost" and "holding cost" refer to the same concept: the annual cost of storing and financing unsold inventory. Some businesses use the terms interchangeably, and others reserve "holding cost" for the storage component alone, so check what a given source includes before comparing figures.
How can I reduce my inventory carrying cost?
Lower carrying cost by reducing average inventory (smaller, more frequent orders), improving demand forecasting to cut safety stock, clearing slow-moving stock, and reducing shrinkage and storage overhead. Reducing order size too far raises ordering and freight costs, so weigh the carrying-cost savings against those added costs before changing order frequency.
Why is my detailed carrying cost different from the simple percentage estimate?
The simple method applies one flat rate to average inventory, while the detailed method sums your actual capital, storage, insurance, shrinkage, obsolescence and admin costs. A gap between the two usually means your actual cost structure differs from the flat rate assumed, for example higher shrinkage or a higher cost of capital than the rate accounts for.
Can I change the assumptions?
Yes. All inputs can be edited, and advanced assumptions are available below the main inputs. Use values from the same period and currency. Changing display currency changes the symbol, not the underlying amount.
Are my financial numbers saved?
No. Calculations happen locally in your browser. Sharing creates a link containing the inputs, and exporting saves a CSV report to your device. You choose whether to share those artifacts.
