Find your surcharge gap

Use one week of diesel gallons, all miles driven, the miles paid a fuel surcharge and the MPG in your surcharge agreement. Include empty miles in your total. Your recovery percentage is calculated for you.

For a per-mile agreement, the added surcharge is the diesel increase divided by contract MPG, multiplied by surcharge-paid miles. Extra fuel cost is the same increase multiplied by gallons used. The difference is your gap. Recovery can exceed 100% if the formula pays more than your actual increase.

Look at the fuel surcharge schedule in your rate agreement. A formula that adds 1¢ per mile for each 6¢ diesel increase has a 6 MPG divisor. Use that number, even if your truck gets different fuel economy.

This measures an additional price rise under an active, fully passed-through per-mile formula. It assumes your pump price and contract index rise together. A percentage-of-revenue surcharge, payment lag, price floor, stepped schedule or partial pass-through needs its own calculation.

The regional stress uses EIA’s national monthly outlook, a 13-week regional price spread and a historical high-stress scenario. It compares that month’s stress price with the observed regional price. It is a scenario for one typical week, not a probability or a cumulative cost over the selected months.
