- Use Load sample for demand 20, lead time 7 days and safety stock 50.

What this tool does not do / Limits
This tool is a general arithmetic aid and is not financial advice. It assumes steady demand and a fixed lead time; variable demand, seasonality and supplier delays change the right reorder point.
