Inventory is cycling at a solid pace. Monitor DSI trends to stay ahead of demand shifts.
How to use it
- Enter COGS and either beginning plus ending inventory or average inventory directly, then choose annual, quarterly, or monthly period. Use cost values rather than revenue so the turnover ratio is not inflated by markup.
- Read turnover ratio, DSI, annualized turnover, rating, and the built-in industry benchmarks. As a rough benchmark, grocery often runs 14-20 turns, retail 8-12, e-commerce 6-10, and manufacturing 4-8.
- Interpret the rating with context: annualized turnover below 4 often means excess stock and tied-up cash, while levels above 20 can signal stockout risk and supplier strain. A rising DSI trend usually means demand is slowing or purchasing discipline is weakening.
- Use the result to decide whether to cut purchase orders, clear old stock, rebalance SKUs, or add safety stock. If turnover looks high overall but certain categories still age badly, manage by SKU group instead of celebrating a blended average.
- Re-run monthly and around seasonal inventory builds. Track DSI and annualized turnover by category over time because the early warning is usually a trend change, not a single bad month.
Questions people usually ask
What is a good inventory turnover ratio?
It varies by industry. Grocery stores typically see 14-20 turns per year, retail 8-12, and manufacturing 4-8. Higher turnover means faster sales but can risk stockouts.
What is days sales of inventory (DSI)?
DSI tells you how many days it takes on average to sell your entire inventory. Lower DSI means faster sales. Calculate it as 365 divided by your turnover ratio.
Should I use COGS or revenue for turnover?
Use COGS (cost of goods sold) for accuracy. Revenue includes markup, which inflates the ratio and makes comparisons unreliable.
Can inventory turnover be too high?
Yes. Very high turnover can indicate understocking, leading to stockouts and lost sales. Balance efficiency with adequate supply.
