How this is calculated

Rounds use weeks where UPS published a Ground rate and the EIA diesel price is known.

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.
