Dimensional weight calculator for UPS and FedEx
Enter a box and its weight to see the dimensional weight, the billable weight, and what the difference costs, including the fuel on top.
Results
- Dimensions are rounded up to the next inch and weights up to the next pound, as UPS and FedEx do.
- A larger divisor in your contract lowers DIM weight; 139 is the standard daily-rate divisor.
How this is calculated
DIM weight = L × W × H ÷ divisor, rounded up. Billable = the greater of DIM and actual.
Rates shown as defaults come from carrier publications or each carrier’s published table applied to the EIA price; see the methodology. Estimates and examples are labeled. Results are illustrative and do not represent any carrier’s reported financial results.
