Fuel Surcharge Calculator

Calculate trucking fuel surcharge per mile and total customer line items from diesel price, base price, MPG, miles, or a pegged threshold schedule.

About the Fuel Surcharge Calculator

Carriers, brokers, shippers, and private fleets use a fuel surcharge calculator to turn diesel price changes into a transparent line item. Enter the current fuel price, base price, miles, and truck fuel economy to estimate the surcharge for a lane or invoice. It helps separate volatile fuel recovery from the underlying freight rate.

How it works

  1. Enter the agreed base fuel price from the contract or tariff.
  2. Add the current diesel benchmark price used for billing.
  3. Enter route miles and the truck MPG assumption.
  4. Calculate the fuel surcharge and show it as a separate customer line item.

Frequently asked questions

How is a trucking fuel surcharge calculated?

A common method subtracts the base fuel price from the current fuel price, divides by the agreed MPG, and multiplies by billable miles. Contracts may use a table, percentage, or different benchmark.

Which diesel price should I use?

Many U.S. contracts reference the U.S. Energy Information Administration on-highway diesel price, often national or regional. The correct benchmark should be stated in the shipper-carrier agreement.

Why is base fuel price important?

The base price represents the fuel cost already assumed in the linehaul rate. The surcharge usually recovers only the difference between current fuel and that base.

Should surcharge miles equal odometer miles?

Not always. Billing may use practical miles, shortest miles, hub miles, loaded miles, or a route guide. The mileage basis should be defined before invoicing.

Can a fuel surcharge be negative?

Some agreements allow the surcharge to fall to zero or become a credit when fuel drops below the base price. Others floor it at zero, so the contract language controls.
