Reorder Point

When stock drops to this level, place your next order. Don't wait — this is your trigger.
ROP = (D × L) + SS
= (25 × 5) + 40
= 125 + 40
= 165 units
= (25 × 5) + 40
= 125 + 40
= 165 units
How it works
The reorder point is the stock level that triggers a new purchase order. It needs to cover the demand you'll see while waiting for the new shipment to arrive — plus a buffer for unexpected spikes or delays.
Average daily sales × lead time = how much you'll sell while waiting for the delivery. Safety stock = the extra buffer on top. Add them together and you get the number that says "order now."
Worked example — coffee shop reordering beans
- You sell bags of beans:25/day
- Supplier delivers in:5 days
- Your safety stock buffer:40 bags
- Lead demand (25 × 5):125 bags
- Reorder when stock drops to:165 bags
