| Step | Math | Result |
|---|---|---|
| Velocity (in-stock days only) | 160 units ÷ 56 in-stock days (0 stockout days excluded) | 2.9 / day |
| Daily demand variability (σ) | sample std. dev. of units/day on in-stock days | 0.7 |
| Safety stock | z(95%) 1.65 × σ 0.7 × √lead time 30d = 7 | 7 units |
| Reorder point | velocity 2.9 × lead time 30d + safety 7 | 93 units |
| Inventory position | on hand 90 + incoming 0 | 90 units |
| Days of cover | position 90 ÷ velocity 2.9 | 31.5 days |
| Order by | today + ⌊(position 90 − reorder point 93) ÷ velocity⌋, min today | Nov 14 |
| Suggested quantity | target 113 (velocity × (lead 30d + review 7d) + safety) − position 90; MOQ 0, case pack 1 | 23 units |
