Why the cheapest box is not always the cheapest shipment
A low-cost carton can still increase dimensional weight. ShippingMath compares packaging cost and estimated shipping cost together, while rejecting boxes that cannot fit the product even after rotation.
What the estimate includes
- The greater of scale weight and calculated dimensional weight.
- The packaging cost entered for each available box.
- Your estimated carrier cost for each billed weight unit.
- Product cost, other order fees and the target margin when supplied.
Planning estimate: carrier prices, surcharges, measurement methods and contract rules can differ. Confirm the selected box and actual label price before changing packaging.
