Inventory & shipping
Inventory reorder point calculator
Reorder before you run out. Combine your sales rate, supplier lead time and a safety buffer to get a reorder point and an order quantity.
How it is calculated
- Safety stock = daily sales × safety days.
- Reorder point = daily sales × lead time + safety stock.
- Days until reorder = (stock − reorder point) ÷ daily sales.
- Order quantity = daily sales × cover days.
