Frequently Asked Questions
What is dimensional weight?
Carriers charge by actual weight or dimensional weight, whichever is greater. DIM weight = (L x W x H) / divisor. Large, light packages may cost more than weight suggests.
How accurate are these estimates?
Estimates are based on standard published rates. Actual costs may vary with negotiated rates, surcharges, and fuel adjustments. Use for comparison and planning.
Which carrier is cheapest?
It varies by package and destination. USPS often wins for small packages, UPS/FedEx for larger items. The calculator shows all options for easy comparison.
