Fuel Surcharge Guide: What Truckers Need to Know in 2026

Fuel surcharges are supposed to protect you from fuel price fluctuations. Here's how to make them work for you.

How Fuel Surcharges Work

A fuel surcharge is an additional charge on top of the base rate, calculated based on:

Current diesel price

Your truck's MPG

Base fuel price (the "trigger" price)

The Formula

Fuel Surcharge = (Current Price - Base Price) / Your MPG

Example:

Current diesel: $3.80/gallon

Base price: $2.50/gallon

Difference: $1.30/gallon

Your MPG: 6.5

Fuel surcharge = $1.30 ÷ 6.5 = $0.20/mile

Common Mistakes Truckers Make

1. Not Negotiating FSC

Many drivers accept whatever the broker offers. Negotiate. Know your MPG and calculate what you deserve.

2. Using Outdated MPG

If your MPG is 6.0 but you're calculating at 7.0, you're leaving money on the table.

3. Forgetting Base Price

Some brokers use a low base price ($1.50 or $2.00) to minimize surcharges. Know what base you're agreeing to.

4. Not Including Deadhead

Fuel surcharges should apply to all miles — loaded AND deadhead.
