How to Use This Tool
Enter your total inventory value, the number of months you plan to hold the stock, and the annual cost rates for storage, capital, insurance, and obsolescence. Select your preferred display unit (USD or percentage) and click Calculate. Use Reset to clear all fields and start over.
Formula and Logic
The tool calculates total carrying cost by summing the annual rates for storage, capital, insurance, and obsolescence. It then applies this total rate to the inventory value, adjusts for the holding period in months, and provides results in your chosen unit. The monthly cost is derived by dividing the annual cost by 12.
Practical Notes
- For e-commerce sellers, consider seasonal demand when estimating obsolescence risk.
- Small businesses should benchmark storage rates against local warehouse fees.
- Capital cost rates often reflect your business's cost of borrowing or opportunity cost.
- Insurance rates may vary based on product type and location—check with your provider.
- Use this tool to evaluate pricing strategies and maintain healthy profit margins.

Frequently Asked Questions
What if my inventory value changes frequently?
Use an average inventory value over the holding period for more accurate estimates. Update the calculation monthly for dynamic stock levels.
Can I use this for perishable goods?
Yes, but increase the obsolescence rate to account for spoilage. For highly perishable items, consider shorter holding periods.
How do I determine the capital cost rate?
Use your business's average loan interest rate or a conservative estimate like 5-10% if using internal funds. This reflects the cost of tied-up capital.
Additional Guidance
