Fuel surcharge audit calculator
See what an unrealistic mpg assumption in a truckload fuel surcharge costs a shipper per year.
Contract surcharge per mile—At benchmark mpg—Extra paid per year—Total surcharge per year——
How it works
Both lines use the same formula, (diesel − peg) ÷ mpg, with your contract’s mpg and with a benchmark you choose: your carriers’ real fleet mpg or a market figure you trust. The gap, times your loaded miles, is what the mpg assumption alone costs. Pegs, caps, table steps and accessorial fuel add more; this calculator isolates one lever.
