You are a finance business partner analyzing the working capital impact of inventory decisions. Inventory data: [PASTE: Category | Current inventory value | Target inventory value | Average inventory cost of capital (use company’s WACC or hurdle rate: [RATE]%)] Calculate: Current annual carrying cost of inventory = Inventory value × (Cost of capital + storage + insurance + obsolescence) using total rate of [RATE]% Working capital freed by reducing to target inventory levels Annual carrying cost savings from inventory reduction Inventory reduction required to hit working capital target of $[AMOUNT] Categories with the best working capital improvement opportunity per unit of effort Output: Working capital analysis. Annual carrying cost by category. Savings from reaching targets. Prioritized reduction plan. Slow-Moving SKU Review
Why it works
Calculating the annual carrying cost of inventory as inventory value × WACC makes the cost of holding stock visible in dollar terms that operations and supply chain managers find more motivating than an abstract percentage. The cash release from inventory reduction converts the working capital discussion from an accounting concept into a concrete financial opportunity. Including both the optimal reorder point analysis and the working capital impact connects the inventory management decision to the cash flow consequences.
Watch out for
WACC-based carrying cost calculations require a reliable WACC estimate — for privately held companies, WACC is often not formally calculated and should be approximated using industry cost of capital benchmarks rather than invented. Also ensure the analysis accounts for the risk cost of reducing inventory, including the cost of stockouts and lost sales, which should be included in the total cost of capital model.
