Inventory Turnover Ratio in Days: Formula & Benchmarks

The inventory turnover ratio in days measures how long your stock sits before it sells. The formula is straightforward: divide 365 by your inventory turnover ratio. For ecommerce sellers on marketplaces like Shopee, Lazada, and TikTok Shop, this metric is critical — a low number means products move fast and cash flows freely, while a high number signals capital trapped in slow-moving goods.
