How it's calculated
- Daily usage = Monthly usage ÷ Working days per month.
- Total lead days = Production lead time + Shipping time + Customs & delivery buffer + Safety stock days.
- Reorder point (ROP) = Daily usage × Total lead days. Rounded up to a whole piece.
- Cover days = Months per order × Working days per month. Suggested order quantity = max(MOQ, Daily usage × Cover days).
- Stock runway = Current stock ÷ Daily usage.
- Latest order date = Today + (Stock runway − Total lead days). If the result is below zero, the tool shows that you should have ordered already.
- Orders per year = Annual usage ÷ Suggested order quantity, rounded up. Annual usage = Monthly usage × 12.
Assumptions: demand is steady, working days are treated as calendar days for the date estimate, and safety stock is held as a reserve on top of lead time. Lead times and shipping times are not pre-filled because they depend on your project and quotation.

A worked example
This example uses the default values: 30,000 pcs per month, 30 working days, 5-day buffer, 14-day safety stock, 10,000 pcs MOQ, monthly orders and 0 pcs in stock. Lead times are left blank by default, so the reorder point is shown as a formula.
| Item | Calculation | Result |
|---|---|---|
| Daily usage | 30,000 ÷ 30 | 1,000 pcs per day |
| Reorder point | 1,000 × (production + shipping + 5 + 14) | 19,000 pcs plus 1,000 pcs for each day of production and shipping time |
| Suggested order quantity | max(10,000, 1,000 × 30 cover days) | 30,000 pcs |
| Stock runway | 0 ÷ 1,000 | 0 days |
| Orders per year | 360,000 ÷ 30,000 | 12 orders |
With zero stock, any lead time above zero means the tool shows that you should have ordered already. Enter your own stock and lead times to see your latest order date.
FAQ
Why should I order before my stock runs out?
Custom printed packaging needs production, shipping, customs clearance and delivery before it reaches your filling line. If you wait until stock is low, a line stoppage becomes likely, so the reorder point includes all of these days plus a safety reserve.
How do I find my production lead time?
Use the lead time stated in your quotation or confirmed by your supplier for the specific product, quantity and print specification. It can change with order size and season, so please confirm with your data.
What happens if my MOQ is higher than what I need?
The calculator uses the MOQ as the order size. You will see fewer, larger orders per year and a longer stock runway. Compare this with the cost of holding stock and the shelf life of your packaging.
How much safety stock should I keep?
It depends on how stable your demand is and how reliable your logistics are. The 14-day default is a typical value, please confirm with your data, and increase it for seasonal peaks or long shipping routes.
Does this tool include artwork approval or plate making time?
Not separately. If those steps are part of your timeline for a new design, add them to the production lead time field so the plan covers the full period.
