Inventory Turns Calculator: How Fast Does Your Stock Move?
An inventory turns calculator shows how many times you use up your stock in a period and how many days of stock you hold. Enter opening stock, purchases, closing stock and the number of days, and the tool gives usage, average stock, turns and days on hand.
How to read your result
- Usage in period: opening stock plus purchases minus closing stock.
- Average stock value: the mean of opening and closing stock.
- Turns: usage divided by average stock. KSh 620,000 of usage on KSh 190,000 of average stock is about 3.26 turns.
- Days on hand: average stock divided by usage, times the days in the period. The same example gives about 9.2 days.
- Fresh and dry stock turn at very different speeds, so run them separately.

Frequently asked questions
Is a higher turn always better?
No. Very fast turns can mean you are running out or ordering too often. Very slow turns mean cash and food are sitting idle. Look for a steady figure that matches how you buy.
Why separate fresh from dry stock?
Fresh produce may turn many times in a month while dry goods turn slowly. Mixing them hides the problem in both.
What should I do with slow-moving items?
Check the par level, stop reordering until stock falls, and look for a dish that can use it before it expires.
