Methodology

Sources

• Carrier rates: UPS, FedEx, OnTrac, DHL Express, DHL eCommerce, Amazon Air Cargo and USPS pages, read on a schedule.
• Fuel prices: EIA weekly U.S. on-highway diesel, U.S. Gulf Coast jet fuel, and regional diesel.
• Market signals: EIA weekly spot prices for New York Harbor and U.S. Gulf Coast ultra-low sulfur diesel, WTI and Brent crude.
• Cross-check: carrier-published values from our sister site’s public feed, used only when we could not read the carrier directly, and timestamped with the sister site’s read time.
• Outlook: EIA Short-Term Energy Outlook.

Status labels

Carrier published

Confirmed from the carrier’s own publication.

Calculated

Derived from the carrier’s published table and the applicable EIA fuel price. Subject to confirmation against the carrier’s published rate.

Estimated

Based on incomplete information, such as an averaging window the carrier does not fully publish.

Stale

Not verified within its expected update window. The last known value is shown with its date.

Unavailable

A reliable rate cannot be determined right now.

Per $100

Fuel per $100 equals the percentage surcharge expressed in dollars. It applies to the charges the surcharge is assessed on, which depend on your contract.

Timing

Sources are checked about every six hours. A verification time changes only when a value is actually read from its source; reloading a page never changes it.

Corrections

If you find an error, email sales@contractoptimizer.com. We correct it, note it and keep history intact.
