How this calculation works

Billable weight is normally the greater applicable value: actual weight or dimensional weight. ParcelCal runs the calculation in your browser; no package or shipment information is uploaded.

FORMULA

DIM weight = Length × Width × Height ÷ DIM divisor

Billable weight is normally the greater applicable value: actual weight or dimensional weight.

Worked example

20 × 15 × 10 in carton at divisor 139

1.Cubic size: 20 × 15 × 10 = 3,000 in³
2.DIM weight: 3,000 ÷ 139 = 21.58 lb
3.Rounded DIM weight: 22 lb

If scale weight is 12 lb, the estimated billable weight is 22 lb.
