About this tool
Reorder point = (average daily sales × supplier lead time) + safety stock. It's the stock level at which you should place your next order so you don't run out before the new delivery arrives. Safety stock is extra buffer on top of that, to absorb day-to-day variation in demand and the odd late delivery — the bigger and less predictable either of those are, the more safety stock you'll want.
This is a quick planning aid based on simple averages, not a substitute for your own inventory or forecasting system — use it as a sanity check or a starting point rather than the final word.
