Frequently Asked Questions
What is a good inventory turnover ratio?
It depends on your category. Fast moving consumer goods often turn 8 to 12 times a year, while furniture or jewelry may turn 2 to 4 times. Compare against your own history first; a rising ratio usually matters more than any single benchmark.
How is inventory turnover calculated?
The calculator divides your cost of goods sold by your average inventory value for the same period. It also converts the ratio into days of inventory, which tells you roughly how long a typical item sits on the shelf before it sells.
Is the Inventory Turnover Calculator free?
Yes, it is free after creating a Brainito account. Run the numbers for your whole store or one category at a time, and recheck each quarter to catch slowdowns before they tie up your 2026 buying budget.
