How this calculation works

A smaller divisor produces a higher dimensional weight for the same carton. ParcelCal runs the calculation in your browser; no package or shipment information is uploaded.

FORMULA

Shipping DIM weight = Package volume ÷ carrier divisor

A smaller divisor produces a higher dimensional weight for the same carton.

Worked example

Compare a 2,400 in³ shipment

1.At divisor 139: 17.27 lb
2.At divisor 166: 14.46 lb
3.Compare each rounded result with actual weight

The rate method, not only the box, determines the billable-weight estimate.
