Method
ROP = (Daily sales × Lead time in days) + Safety stock. Safety stock = Daily sales × Safety cover days.
Frequently asked questions
How do I estimate safety cover days?
Use 5–10 days for stable products, 14+ days for volatile categories or long-haul suppliers. If your lead time has high variability, safety stock protects against it.
Should I use average or peak daily sales?
Use a rolling 28-day average for planning, and check against peak season demand for Q4 / holiday planning.
