How this calculation works

Carrier rating systems can add minimums, surcharges, multi-piece rules, and contract-specific rounding. ParcelCal runs the calculation in your browser; no package or shipment information is uploaded.

FORMULA

Billable weight = Greater of actual weight and applicable DIM weight

Carrier rating systems can add minimums, surcharges, multi-piece rules, and contract-specific rounding.

Worked example

Actual weight wins

1.Carton: 12 × 10 × 8 in = 960 in³
2.960 ÷ 139 = 6.91 lb
3.Actual scale weight: 11 lb

The estimated billable weight is 11 lb because actual weight is greater.
