How this calculation works
Minimum stock using lead-time demand plus a user-selected days buffer.
Worked starting inputs
Example inputs: Daily Demand = 10.0, Reorder Lead Days = 5.0, Service Buffer Days = 4.0. Expected result: Suggested minimum units: 90. 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.
