Work through the task
- Use actual usable stock and consumption expressed in the same unit. Keep quarantined or unusable inventory outside available stock.
- Estimate coverage and lead-time demand using a stated consumption assumption. Safety stock is an entered planning quantity, not a service-level guarantee.
- Check supplier MOQ and overrun before ordering. Review changes in demand, lead time and expiring packaging artwork.
Tools for this job
Packaging Inventory Coverage Calculator
Convert available usable packaging stock into operating days at an explicit daily usage rate.
Open calculator →Packaging Reorder Point Calculator
Calculate a simple replenishment trigger from daily demand, supplier lead time and explicitly chosen safety stock.
Open calculator →Packaging MOQ Cost Calculator
Calculate the cash, film area, approximate pack quantity and inventory commitment represented by a supplier minimum order.
Open calculator →Packaging Order Overrun Cost Calculator
Estimate the extra units and invoice amount at an entered supplier overrun percentage.

Usable stock of 12,000 units at 1,000 units/day covers 12 days under constant consumption. Five days of lead time plus an explicitly chosen 2,000-unit buffer gives a 7,000-unit reorder threshold under that simplified model.
Use your supplier specification and quotation. These numbers demonstrate the arithmetic; they are not market prices or a packaging suitability assessment.
Checks before you decide
- Usable stock in matching units
- Actual lead time and consumption pattern
- Buffer assumption and artwork obsolescence
