What is a Reorder Point?
A reorder point (ROP) is the stock level at which you need to place a new purchase order to avoid running out of an item. It's set above your safety stock to account for the time it takes your supplier to deliver.
Without a reorder point, you either order too late (causing stockouts) or too early (causing excess inventory and wasted cash).
The Reorder Point Formula
- Average Daily Usage: How many units you consume per day on average.
- Lead Time: Days between placing an order and receiving it from your supplier.
- Safety Stock: Your buffer stock — the absolute minimum you want to hold. This is the same as your minimum stock level.
Reorder Point vs Minimum Stock
These two values are often confused:
| Term | Meaning | Action |
|---|---|---|
| Reorder Point | Stock level at which you ORDER | Place a purchase order immediately |
| Minimum Stock | Absolute floor — safety buffer | Escalate — order is already overdue |
Reorder point is always higher than minimum stock. The gap between them equals the stock consumed during lead time.
