Frequently asked questions

What is inventory turnover?

Inventory turnover (turns) is how many times per year the average inventory on hand is sold through and replaced. Higher turns = a leaner stock profile; lower turns = more cash tied up in stock for longer.

Inventory Turnover

What's a healthy inventory turnover ratio?

There is no universal numeric benchmark for this decision. The right comparison depends on the industry, geography, business model, time period and exact metric definition. Use the business’s own history, economics and explicit target unless a verified benchmark matching that scope is available.

Inventory Turnover

How do I use this with revenue but no COGS figure?

Use the calculator's revenue × COGS% helper: enter revenue and an estimated COGS% from your gross margin — the calculator back-solves COGS and divides by average inventory for you.

Inventory Turnover

What does "days of inventory on hand" mean?

Days of inventory on hand = 365 ÷ turns. At 4 turns/yr that is 91 days; at 8 turns/yr, 46 days. The lower the days, the leaner the stock-and-cash profile.
