About this tool
Inventory turnover (COGS ÷ average inventory) is the cleanest measure of how efficiently you're using working capital. Low turnover = cash trapped in stock; high turnover = lean ops but stockout risk. Compute turnover, days of inventory, and benchmark against category.
Low turnover vs high turnover
Turnover below your category benchmark = cash trapped in stock and higher markdown risk. Turnover above = lean ops, but stockouts become likely without sharp safety-stock discipline. Most operators target slightly above the category average — efficient enough to free cash, conservative enough to avoid losing bestsellers.
Levers to raise turnover
- • Cull slow SKUs (the bottom 30% usually contributes <5% of revenue)
- • Negotiate smaller, more frequent POs with key suppliers
- • Promote tail inventory rather than ordering more of it
- • Pre-sell new SKUs (waitlist) to validate before manufacturing
