Reorder point calculator
Reorder when stock falls to what you sell while the supplier delivers, plus a safety buffer. If you sell 12 a day, delivery takes 4 days and you keep 2 days' safety stock, reorder at 12 × (4 + 2) = 72 units.

How it’s calculated
- Reorder point = average daily sales × (delivery days + safety days).
- Order quantity = average daily sales × days each order should last.
- Safety stock = average daily sales × safety days.
Worked example
A pharmacy sells 20 strips of a paracetamol brand a day; the distributor delivers in 2 days; it keeps 1 day of safety stock. Reorder point = 20 × 3 = 60 strips. To order every 10 days, order 200 strips.
Limits
- Assumes steady daily sales. For seasonal items (Eid, winter), use the recent daily rate.
- Doesn't consider minimum order quantities or carton sizes.
