How a fuel surcharge works

Peg table (indexed)

The classic freight model. You agree a baseline diesel price. For every fixed step the current price rises above it, the surcharge on the linehaul goes up by a set percentage — so the carrier is covered when fuel climbs, and the rate falls back when it eases.

Straight pass-through

Simpler: the surcharge is just the difference between today's diesel and your baseline, per litre burned. Multiply by the fuel a job uses and you have the extra to invoice. Common in Europe and Asia.
