This educational calculator runs in your browser. It does not upload the values or reproduce ReOrder's full forecast, supplier-minimum or cash-allocation logic. Only count inbound stock that will be usable in time.
Your example
- Reorder trigger
- 54 units
- Inventory position
- 29 units
- Target including review period
- 82 units
- Unrounded requirement
- 53 units
- Rounded quantity to review
- 60 units
The example inventory position is at or below the reorder trigger.
This is a quantity for review, not an instruction to place an order.
The calculation
Reorder trigger = daily demand × lead time + safety stock.
Target = daily demand × (lead time + review period) + safety stock.
Requirement = the greater of zero or target − available − reliable inbound. Round that requirement up to the next full case pack.
Default illustration: 2 × 21 + 12 gives a 54-unit trigger. The 35-day target is 82, and subtracting 29 available leaves 53 units. A case pack of 12 rounds that to 60. These are illustrative figures, not merchant results.

Demand changes, stockouts, supplier minimums and available cash need a fuller review. Read the reorder-point guide and ReOrder's forecasting methods.
