Stock Runway Calculator
Stock Runway Calculator
Measure unreserved stock against average daily demand and a supplier wait.
Reserved units are not freely available for new orders. A runway estimate should begin with unreserved inventory.
Enter current stock, reservations and average daily demand. Compare the available days with the supplier waiting time.
How to use Stock Runway Calculator
- Enter on hand stock, reserved stock, expected daily demand and days until next receipt.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The available stock basis helps distinguish inventory physically present from units already promised.
Before you use the result
Incoming stock is not included before receipt. Daily demand is an entered average; zero demand leaves runway undefined rather than promising permanent stock availability.
Questions about Stock Runway Calculator
Does incoming stock extend today's runway?
Not before it is received in this model. Review incoming deliveries separately from currently available stock.
What should I check before using Stock Runway Calculator?
Check On hand stock, Reserved stock, Expected daily demand and Days until next receipt. Use the exact units shown beside the controls and replace any example values with your own inputs.
