Inventory Reorder Point and Safety Stock: A Working Guide

A linkable inventory reference covering reorder point, safety stock, EOQ, demand rate, lead time, and service assumptions.

Intended audience: Ecommerce operators, supply-chain teams, and operations educators

Key points

• Reorder point combines expected demand during lead time with safety stock.
• Safety stock protects against demand or lead-time variability but increases carrying cost.
• EOQ is a model, not a purchase instruction; review supplier constraints and cash availability.
