How it is calculated

Frequently asked questions
Should I use actual or dimensional weight?
Use the weight the carrier will bill, usually chargeable weight after comparison.
Is the result an actual carrier quote?
No. The calculator applies your inputs mathematically; carriers may use minimums, zones, tiers, fees and different rounding rules.
What matters most before comparing?
Keep units, period and cost scope consistent, and know whether pricing uses actual, dimensional or chargeable weight.
