The trigger is lead-time demand plus the safety allowance. Current availability and credible inbound supply are shown against that trigger but do not change the trigger itself.
How to use the result
Treat the output as a transparent planning comparison. Check the item, unit, location, status, dates and open transactions before acting. A mathematically correct result can still be operationally wrong when the inputs describe unavailable or incorrectly recorded stock.
Print or copy the result with the assumptions used. Replace estimates with verified information as receipts, counts, inspections and returns become known.
Important boundary
This calculator is not an accounting record, audit, purchase authorization, safety procedure, engineering result, stock policy or guarantee against shortages, excess, damage or loss.
