Define the boundary of the comparison
A landed-cost comparison adds the costs required to bring the packaging to the agreed destination. Decide which destination and charges you are comparing, then use that boundary for every supplier. Otherwise, an ex-works quotation and a delivered quotation can appear comparable while covering different services.
Start with purchased quantity multiplied by its unit price. Add entered freight, tooling, setup and other charges that belong to the order. Add duties or taxes only with a verified treatment for your transaction; the calculator is an arithmetic tool and does not determine tax eligibility or customs rules. Avoid adding a charge a second time when it is already included in the supplier total.
Allocate fixed charges over the right quantity
Suppose 1,000 kg of film costs €3.00/kg and transport costs €180. The delivered total is €3,180 and the delivered kilogram price is €3.18. For a 250 kg order with the same €180 transport charge, the effective price is €3.72/kg. The difference comes from allocation, even though the material price is unchanged.
A one-time €600 tooling charge allocated across 20,000 packs adds €0.03 per pack, or €30 per thousand. If the tooling is reused on a later order without another charge, do not carry that first-order allocation into every repeat quotation. Show first-order and repeat-order economics separately.
Account for a minimum order honestly
If demand is 600 kg but the minimum order is 1,000 kg, the buyer pays for 1,000 kg. At €3.00/kg plus €180 transport, the cash requirement is €3,180. Dividing that entire amount by 600 kg gives €5.30 per kilogram of current demand, but this is not the delivered price per purchased kilogram: 400 kg remains in inventory.
Keep purchase cost, immediate requirement and surplus quantity separate. Surplus may be useful for later production, or it may become obsolete. The price calculator cannot decide that outcome. Compare the extra cash requirement and storage implications alongside the normalized unit cost.
Check useful quantity and recurring costs
Use net material weight for material pricing and gross shipment weight only when the freight basis calls for it. If you expect a known unusable fraction, calculate the cost per useful kilogram or accepted piece separately from cost per purchased unit.
Save the quote quantity and the fixed-charge assumptions with the result. Freight can change with shipment size, route and service; do not assume the same fixed charge applies at every volume. A comparison is strongest when each supplier provides a quote for the same intended order.
Common questions
Should tooling be included in every order?
Include it whenever it is actually charged. Separate first-order charges from recurring charges, and state any allocation assumption.
Does a larger MOQ mean a lower total cost?
A lower unit price can still require more cash and leave unused inventory. Compare the actual purchase total and surplus quantity as well as unit cost.
