Inventory Turnover Analysis

Inventory turnover measures how many times you sell and replace inventory annually. Calculate by dividing cost of goods sold by average inventory. With $500,000 COGS and $100,000 average inventory, turnover is 5 times per year (every 73 days). Higher turnover means efficient inventory management and strong sales relative to stock levels.

Optimal turnover varies by industry - grocery stores turn inventory 15-20 times yearly, furniture retailers 4-6 times, jewelry 1-2 times. Higher turnover reduces holding costs, storage needs, and obsolescence risk but may indicate stockouts. Lower turnover ties up cash and increases carrying costs but might enable bulk purchasing discounts.

Improve turnover by optimizing inventory levels, improving demand forecasting, negotiating faster supplier deliveries, reducing slow-moving items, and boosting sales through marketing. Track turnover by product category to identify problems. Days inventory outstanding shows how long products sit before selling - lower is generally better.
