Fuel Surcharge Calculator for Trucking & Freight

Calculate fuel surcharge per mile and total fuel surcharge using current diesel price, base fuel price, baseline MPG and load miles.

Planning only: Fuel surcharge programs vary by carrier, customer contract, fuel table and diesel index. Verify the current diesel price and agreement terms before billing or quoting.

Calculate Fuel Surcharge

Diesel price, base price, MPG and miles

Common examples are $3.00 or $3.25, but contracts vary.

What is a fuel surcharge?

A fuel surcharge is an extra charge used to offset fuel price changes. In trucking and freight, it is often calculated from a diesel index, a base fuel price and a baseline MPG or fuel efficiency assumption.

Fuel surcharge protects carriers from sudden diesel price increases and helps brokers or shippers separate linehaul pricing from fuel movement.

Fuel Surcharge Formula

Fuel difference = Diesel price − Base price
Surcharge per mile = Difference ÷ MPG
Total surcharge = Surcharge per mile × Miles

When fuel surcharge matters

Linehaul quotes

Separate linehaul revenue from fuel movement.

Broker pricing

Protect margin when diesel changes after quote discussions.

Carrier billing

Estimate the surcharge amount to add to a load invoice.

Rate per mile checks

Fuel surcharge changes the true revenue per mile.

Fuel Surcharge Calculator FAQ

How do I calculate fuel surcharge per mile?

Subtract the base fuel price from the current diesel price, then divide by the baseline MPG.

What if diesel price is below the base fuel price?

In many surcharge programs, the surcharge becomes zero. Some contracts may handle this differently.

Where do I get the diesel price?

Many U.S. programs use a published diesel index, but you should use the exact index specified in your agreement.

Does fuel surcharge guarantee profit?

No. It only offsets fuel movement. You still need to check total cost, deadhead, accessorials and rate per mile.
