The purchasing question
A beverage-carton budget needs a clearly defined system boundary. Closures, straws and other separately purchased items can make a material difference to the complete pack cost. Start with the packaging bill of materials and remove components that are already included in a supplier quote.
Calculation method
Add the carton body and each required component cost per accepted pack. Add order-level freight and setup over the applicable quantity. Multiply by a known planned pack volume for a period budget, keeping the period and demand assumption explicit.
Worked example
A €0.12 carton body and €0.03 closure create a €0.15 component subtotal. An additional €500 shipment charge over 100,000 packs adds €0.005 per pack. The stated delivered system cost is €0.155, or €155 per thousand. At a planned annual volume of 2 million identical packs, that unit assumption implies €310,000.
The annual figure is a scenario using supplied volume, not a forecast of customer demand. Shipment frequency may change freight allocation, and component prices can change across quantity tiers. Test different volumes rather than treating a single shipment cost as constant for every future order.
Checks before using the result
- Match the complete component list.
- State the budget period and finished-pack quantity.
- Use freight assumptions consistent with planned shipment sizes.
Common questions
Should every calculator display annual spend?
Only when the annual quantity or shipment frequency is known or explicitly entered as an assumption. Otherwise use cost per order or a stated number of deliveries.
