Your Reorder Point
165 units
= (25 × 5) + 40 = 125 + 40 = 165 units
When your stock drops to this level, place a new order immediately.
How this works
The reorder point is the stock level that triggers a new purchase order. It needs to cover the demand you'll see while you wait for the new shipment to arrive — plus a buffer for unexpected spikes or delays.
Reorder Point = (Avg Daily Sales × Lead Time) + Safety Stock
- Avg daily sales × lead time — how much you'll sell while waiting for the new order to arrive.
- + Safety stock — the buffer that protects you from demand spikes and supplier delays.
- = Reorder point — place a new order the moment stock hits this number.
Worked example
Coffee shop reordering whole bean bags
You sell about 25 bags of beans per day. Your roaster delivers in 5 days. You keep a safety stock of 40 bags to cover busy weekends and the occasional delayed shipment.
= 125 + 40
= 165 bags
The moment your shelf drops to 165 bags, place the next order. By the time it arrives 5 days later, you'll be right around your 40-bag safety stock — never out of coffee.
When demand is highly variable
This formula assumes fairly stable daily sales. If your sales swing wildly — seasonal products, trend-driven items, or brand-new SKUs — you'll want a larger safety stock and should recompute your reorder point more frequently (weekly or even daily). Automated tools handle this by pulling from your real sales history and recalculating in the background.
