Inventory Turnover Calculator — free online
If you run a shop or a small warehouse, you've probably wondered how fast your stock actually moves. Sitting on goods too long ties up money; selling too quickly can mean empty shelves. We added a free tool that gives you the numbers in seconds — Inventory Turnover Calculator — right in your browser.
What it does
You enter your cost of goods sold (COGS) and your average inventory, and it shows two things: your inventory turnover ratio (how many times you sold and replaced stock) and your days inventory (roughly how many days an item sits before it sells). That's it — clear numbers you can actually use.
Nothing leaves your device
Everything runs in your browser. Your figures aren't uploaded anywhere, nothing is saved, and no account is needed. When you close the tab, it's all gone.
How to use it
- Open Inventory Turnover Calculator.
- Type in your cost of goods sold and your average inventory.
- Read your turnover ratio and days inventory straight away.
It's free with no limit. There are more small tools on the Apps page.
