Fuel Surcharge Calculator

Fuel surcharges use a simple peg-and-step formula: for every step the diesel price rises above your peg, you add a fixed amount per mile. Enter your numbers below to see the current rate and how it scales. This is the same math FuelScope Fleet runs against live regional prices.
