| Step | Math | Result |
|---|---|---|
| Velocity (in-stock days only) | 230 units ÷ 56 in-stock days (0 stockout days excluded) | 4.1 / day |
| Daily demand variability (σ) | sample std. dev. of units/day on in-stock days | 0.9 |
| Safety stock | z(95%) 1.65 × σ 0.9 × √lead time 30d = 8 | 8 units |
| Reorder point | velocity 4.1 × lead time 30d + safety 8 | 132 units |
| Inventory position | on hand 122 + incoming 0 | 122 units |
| Days of cover | position 122 ÷ velocity 4.1 | 29.7 days |
| Order by | today + ⌊(position 122 − reorder point 132) ÷ velocity⌋, min today | Nov 14 |
| Suggested quantity | target 160 (velocity × (lead 30d + review 7d) + safety) − position 122; MOQ 0, case pack 1 | 38 units |
