Reorder point formula

Reorder point = average daily demand × lead time + safety stock.

Example

At 15 units daily demand, eight days lead time and 30 safety stock units, reorder point is 150 units.

Assumptions

The formula assumes stable average demand and lead time. Variable demand requires a more robust safety stock model.
