Inventory Carrying Cost Calculator
Total the cost of holding stock: capital, storage, insurance, shrinkage and obsolescence.
About Inventory Carrying Cost Calculator
Carrying cost is usually 20 to 30 per cent of inventory value a year once capital, space, insurance and obsolescence are all counted. That is why cutting stock releases far more than the working capital alone. Buyers optimise purchase price and ignore carrying cost, which is how a bulk discount of 5% ends up costing more than it saves.
Formula
Inventory Carrying Cost
Carrying cost = average inventory value × (capital + storage + insurance + obsolescence) %
- carrying rate
- Total annual cost of holding stock as a share of its value
