Inventory turnover FAQs
It varies by industry. Grocery stores typically target 12-15x (turn every 24-30 days). Fashion retail: 4-6x (60-90 days). Auto parts: 2-3x (120-180 days). Higher isn't always better—too high means stockouts and lost sales. Our calculator includes industry benchmarks so you can compare apples to apples.
Add beginning inventory and ending inventory for the period, then divide by 2. For example: ($100k beginning + $80k ending) ÷ 2 = $90k average inventory. Use monthly figures for seasonal businesses, annual for stable operations.
DII = 365 ÷ Inventory Turnover Ratio. It tells you how many days on average inventory sits before selling. Example: Turnover of 6 = 60.8 days. Lower DII means faster inventory movement and better cash flow.
Every dollar in inventory is cash not available for payroll, marketing, or growth. Improving turnover from 4x to 6x on $1M inventory frees $333k in working capital. Our calculator shows the exact cash impact of turnover improvements.
Common causes: overstocking, poor demand forecasting, seasonal products out of season, economic downturns, ineffective marketing, or product obsolescence. Our dead stock detector flags items below 1x turnover.
