What costs are included in total inventory cost?

Total inventory cost includes purchase price plus holding costs: storage rent, insurance, depreciation, obsolescence, opportunity cost of capital, and utilities. Holding costs typically run 20-30% of inventory value annually.

What is Economic Order Quantity (EOQ)?

EOQ is the optimal order size that minimizes total inventory costs by balancing ordering costs against holding costs. Formula: EOQ = √(2 × Annual Demand × Ordering Cost / Holding Cost per Unit).

How can I reduce inventory carrying costs?

Implement Just-in-Time inventory, improve demand forecasting, negotiate better supplier terms, optimize storage efficiency, reduce safety stock levels, and increase inventory turnover rate.

What is a good inventory turnover ratio?

Varies by industry. Retail: 5-10x, grocery: 15-20x, manufacturing: 6-12x. Higher turnover reduces holding costs but requires reliable suppliers and accurate forecasting to avoid stockouts.

Essential Fundamentals — Cost components

Total Inventory Costs

Holding Costs: Storage rent, insurance, depreciation, obsolescence, and opportunity cost of capital typically total 20-30% of inventory value annually.
Ordering Costs: Administrative costs, shipping, handling, and inspection fees incurred each time inventory is ordered.

Cost Calculation Methods

Average Inventory Value: Beginning inventory plus ending inventory divided by two provides baseline for holding cost calculations.
Economic Order Quantity: Optimal order size that minimizes combined ordering and holding costs for stable demand items.

Advanced Strategies — Cost reduction tactics

Optimization Methods

ABC Analysis: Classify inventory by value. A-items (high value) need tight control; C-items (low value) can use simpler management.
Safety Stock Balancing: Maintain minimum buffer to prevent stockouts while avoiding excessive holding costs from over-stocking.
