A third metric to evaluate inventory performance is the inventory carrying cost. This cost represents the total expense of holding and storing your inventory, including warehousing, handling, insurance, taxes, depreciation, and obsolescence. A high inventory carrying cost means that you have a large amount of inventory that consumes your resources and capital. A low inventory carrying cost means that you have a lean inventory that optimizes your cash flow and profitability. To calculate your inventory carrying cost, you need to add up all the costs associated with holding your inventory and divide it by your average inventory value. For example, if your total inventory carrying cost is $50,000 and your average inventory value is $100,000, your inventory carrying cost is 50%. To compare your inventory carrying cost with industry standards, you can use online calculators or tools that provide average costs for different industries and products. For example, according to the Inventory Carrying Cost Calculator by The Balance, the average inventory carrying cost for the retail industry is 25%.
