How this calculation works
Reorder when on-hand plus on-order available units approach lead-time demand plus safety stock.
Worked starting inputs
Example inputs: Daily Sales = 12.0, Lead Time Days = 9.0, Safety Stock = 30.0. Expected result: Reorder point units: 138. 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.
