Inventory Turnover & Days of Inventory Calculator
See how fast your stock sells and how many days of it you hold.
How it’s calculated
- Average inventory: beginning plus ending inventory, divided by 2.
- Turnover: cost of goods sold divided by average inventory.
- Days on hand: days in the period divided by turnover.
What a good number looks like
No single number is right. Higher turnover usually means stock sells fast; too high can mean stockouts. Lower turnover can signal slow or excess stock. Track yours over time.
