Reorder Point Calculator

Calculate when to reorder inventory for each SKU based on daily demand, lead time, and safety stock levels.

Reorder Point Formula
ROP = (Avg Daily Sales × Lead Time Days) + Safety Stock

ROP = Reorder Point — the inventory level that triggers a new order

Avg Daily Sales = Average number of units sold per day

Lead Time Days = Number of days between placing and receiving an order

Safety Stock = Extra buffer stock to protect against variability

How to use this calculator

  • SKU Name — A unique identifier for each product (e.g. “Blue Widget 12oz”).
  • Avg Daily Sales — The average number of units you sell per day over a typical period (e.g. last 30-90 days).
  • Lead Time (Days) — How many days it takes from placing an order with your supplier until the stock arrives at your warehouse.
  • Safety Stock — Extra buffer units kept on hand to protect against unexpected demand spikes or supplier delays. Use our Safety Stock Calculator to find the optimal level.
  • Current Stock — (Optional) Your current inventory level. If provided, the calculator will tell you whether you need to reorder now.
