Reorder point calculator
Calculate your reorder point (ROP) from demand, lead time and safety stock — incl. order suggestion (MOQ optional) and traffic light.

Who is this for?
- Ops/inventory teams that want to reduce stockouts without overstocking
- Seller/D2C teams who want a clear per-SKU reorder trigger
- Teams that need to account for MOQ and review cycles pragmatically
Reorder point (ROP): when to reorder
The reorder point (ROP) is a simple trigger: it tells you at which inventory level you should reorder to avoid stockouts during lead time.
This tool combines average daily sales, lead time and safety stock. Optionally, you can include a reorder cycle (review period) and apply an MOQ as a minimum order quantity.

0 = no MOQ (no minimum lot).
If you review/order only every X days, enter X.
Result
How it works
Base model: demand during lead time (L) is (d \cdot L\), where (d) is average daily sales.
Optional: if you review/order every (C) days (reorder cycle), we add the cycle: (ROP = d \cdot (L + C) + SafetyStock\).
Order suggestion: (max(ROP - stock, 0)\). If an MOQ is set, the suggestion is raised to at least MOQ when needed.
Traffic light: yellow within ±10% around ROP, green above, red below.
Quick conclusion
- ROP is a clear reorder trigger (without complex forecasting models).
- Safety stock is the key lever against uncertainty in demand and lead time.
- MOQ and review cadence shape how your practical order suggestion “rounds”.

FAQ
What’s the difference between safety stock and ROP?
Safety stock is your buffer against variability (demand, lead time). The ROP is the trigger level: demand during lead time (optionally incl. reorder cycle) plus safety stock.
When should I enter a reorder cycle?
If you don’t reorder continuously but review/order in fixed intervals (e.g. every 7/14 days). In that case, the reorder cycle increases the ROP conservatively.
How does MOQ affect the order suggestion?
If you trigger a reorder at ROP, the computed shortage can be smaller than your supplier’s minimum order quantity. In that case, we raise the suggestion to MOQ.
How do I pick a reasonable safety stock?
A practical starting point is a buffer in days (e.g. 3–14 days of average sales) or a value derived from historical variability. Safety stock is not static — revisit it after stockouts, supplier delays and seasonality changes.
