Reorder point = daily demand × lead time + safety stock
Use days for both daily demand and lead time. The reorder point is the inventory position that triggers a replenishment review.
Worked example
For 20 units per day, a 14-day lead time and 31 safety-stock units: 20 × 14 + 31 = 311 units.
When to use this formula
This is a continuous-review trigger. Check inventory position, open purchase orders, reserved stock and changes in demand. Periodic review policies need additional coverage.
Formula reference: Read the source explanation.
Is reorder point the same as order quantity?
No. Reorder point tells you when to review replenishment. Order quantity tells you how much to buy.
