How this calculation works
Identify how much of supplier lead time exceeds current inventory coverage.
Worked starting inputs
Example inputs: Stock Units = 85.0, Daily Demand = 12.0, Lead Time Days = 10.0. Expected result: Stock lasts days: 7.08, Expected shortage days: 2.92. These are illustrative numbers, not market rates. Change a value to compare scenarios; download the result if useful.
Assumptions and limitations
Manual estimates depend on your data and assumptions.
Every result depends on the entered values. The tool does not fetch marketplace fees, infer current exchange rates or verify supplier policies. It is informational, not tax or financial advice.
