Fuel Surcharge Calculator
A free fuel surcharge calculator for carriers and owner-operators. Enter the current diesel price, your base price, and your MPG to find your fuel surcharge per mile — and the total to add to any load.
This uses the standard per-mile method: fuel surcharge per mile = (current price − base price) ÷ MPG. Surcharge programs vary by contract — confirm the base price and method with your broker or customer.

How to calculate a fuel surcharge
A fuel surcharge (FSC) protects carriers from swings in diesel prices. It's added on top of the line-haul rate and rises or falls with fuel, so a spike at the pump doesn't eat your margin. The standard per-mile formula is:
Surcharge per mile = (Current price − Base price) ÷ MPG
1. Find the price over base
Subtract your base (peg) price from the current national average diesel price. If current fuel is $4.00 and your base is $1.25, that's $2.75 per gallon over base.
2. Divide by your MPG
Divide the price over base by your truck's average miles per gallon. At 6 MPG, $2.75 ÷ 6 = about $0.458 per mile of fuel surcharge.
3. Multiply by the miles
Multiply the per-mile surcharge by the loaded miles to get the fuel surcharge for that load. On a 500-mile run, that's about $229 on top of your line-haul rate.
