Reorder point calculator.
Estimate the stock level that should trigger a reorder conversation. Start with average daily sales, supplier lead time and the safety stock you want to hold.
A practical starting point
Calculate demand during lead time, then add your buffer.
This calculator uses: reorder point = average daily sales × lead time in days + safety stock. It is a planning prompt, not an automatic purchasing instruction.
Suggested reorder point
10 daily sales × 30 lead-time days + 50 safety stockUse the result carefully
A reorder point is only as useful as the assumptions behind it.
Check the sales window
Use a sales period that represents the decision ahead. Flag promotions, a lost account or a seasonal peak instead of hiding them in an average.
Use realistic lead time
Include supplier production, transit, receiving and quality-release time where it affects availability. A quoted lead time is not always usable stock.
Review inbound before ordering
The formula does not replace a PO review. Confirm inbound quantity and ETA before turning a calculated trigger into a purchase order.
