Understanding Fuel Surcharges in Logistics

Fuel surcharges add up fast. If you ship parcel or freight, they can quietly push your total bill up 20% or more. Here is how they work, why they keep rising, and what you can do about it.

What is a fuel surcharge?

A fuel surcharge is an extra fee a carrier adds to your shipping rate to cover changes in diesel fuel cost. Carriers update the surcharge weekly or monthly so they do not have to renegotiate base rates every time diesel moves.

You will see it as a separate line on your invoice, usually expressed as a percentage of your base shipping charge.

How carriers calculate fuel surcharges

Most carriers tie their fuel surcharge to a published diesel price index. When diesel goes up, the surcharge percentage goes up.

FedEx

FedEx Ground, Home Delivery, International Ground, and LTL Freight services use the U.S. Energy Information Administration (EIA) national on-highway diesel price. FedEx Express uses the U.S. Gulf Coast spot price for kerosene-type jet fuel. The surcharge updates every Wednesday, based on the previous week’s diesel price.

UPS

UPS uses the same EIA national diesel index, rounded to the nearest cent. The surcharge updates every Monday. UPS raised its surcharge table by 1% in January 2026 and again in March 2026. As of March 2026, surcharge bands run from 21% up to 24%+ when diesel sits above $3.55 per gallon.

DHL

DHL updates its base fuel rate monthly. The surcharge percentage scales with fuel price, but the longer update window means it lags FedEx and UPS.

Where fuel surcharges show up on your invoice

Fuel surcharges are not a flat add-on. Carriers apply them on top of your base shipping rate and on top of most accessorial fees, including residential delivery, oversize, additional handling, Saturday service, signature required, and peak surcharges.

This stacking is why a single residential, oversize package can carry 25% to 35% in surcharges before it ever leaves your warehouse.

Why fuel surcharges are climbing in 2026

Diesel hit $5.37 per gallon in early 2026, well above the level both UPS and FedEx had built into their rate tables. Fuel now accounts for over 20% of carrier operating cost.

Two things have happened since:

UPS raised its surcharge table 1% in January and another 1% in March.

FedEx, UPS, and others added Middle East surcharges tied to disruption in shipping lanes.

For an SMB shipper, the same package shipped at the same base rate costs more in 2026 than it did in 2025, even before any peak season fees.

How to lower your fuel surcharge cost

You cannot opt out of fuel surcharges. You can reduce what you pay.

Negotiate the base rate, not the surcharge

Surcharge percentages are public and apply across the carrier’s customer base. The base rate is where you have leverage. A lower base rate makes every surcharge smaller in absolute dollars.

Cut accessorials before they stack

Every dollar of accessorial fees gets a fuel surcharge applied on top. Right-sizing your packaging, switching to commercial addresses when possible, and avoiding delivery area surcharges saves more than most people expect.

Use a 3PL with carrier rate discounts

Higher-volume 3PLs negotiate better base rates than most SMB shippers can on their own. Those better base rates carry through to a smaller surcharge bill every week. More on how that works on our discounted carrier rates page, and a fuller breakdown in 5 ways 3PL Center reduces your shipping costs.
