How to Raise Your Price After Fuel Costs Jump, Without Losing Customers

Your fuel line just jumped, and the next invoice is still ahead of you. Raise the price by recomputing one job, passing only the direct fuel cost, and announcing one clear change before the invoice goes out.

The U.S. national average for regular gasoline on Sept. 12 was $4.3104 per gallon, compared with $4.2950 the day before, $4.1459 a week before, $4.0360 a month before, and $3.1887 a year before. The U.S. national average for diesel on Sept. 12 was a record $6.1602 per gallon, compared with $6.0556 the day before and $3.7029 a year before. Crude oil was priced at $102.43 per barrel on Sept. 16, 2026. August was the first time ever that U.S. gas prices stayed above $4 per gallon for an entire month.

Recompute the cost of one job

Pick one standard job you sell often: a delivery route, a service call, a load, or a site visit. Write down the fuel that job uses, not the fuel your whole fleet uses. Compare the old fuel cost per gallon with the new fuel cost per gallon for that same job, then subtract the old fuel line from the new one.

Do the same for any other variable cost that moves with the job: tolls, parking, permits, driver time if it changes, and parts that vary by route. Keep fixed costs out of this pass. Rent, insurance, and payroll do not tell you how much a job costs. They tell you how many jobs you need to cover the business.

The sheet is finished when it shows the old unit cost, the new unit cost, and the difference. If you cannot write the difference as a dollar amount per job, you are not ready to price.

Mark each line absorb or pass

Now decide what the customer should pay. Direct fuel costs tied to the job usually get the pass label. Repairs that are not tied to the job, slow weeks, and office expenses usually get the absorb label. Small, temporary costs are absorb. Large, likely-to-stay costs are pass.

The common mistake is to pass through everything that feels expensive. Costs not directly tied to the job do not belong in the customer price. Customers accept a fuel-related increase when the math is narrow. They resist when the increase looks like a general raise.

Every cost line needs a label: absorb or pass. The passed lines add up to a total. That total is what you can show on the invoice.

Size the increase to the passed cost

Add the passed cost to the job price, not to your hopes. If the passed fuel cost for a job is a set dollar amount, add that amount to the price for that job. For a package of jobs, add the passed cost for each job in the package. Convert hourly work into an hourly amount using the hours in the job.

Do not round the increase into a tidy amount that looks like a discount. A small, defensible increase is easier to explain than a large increase that also covers your bad month. Add the passed cost, then check that the new price still leaves you the margin you need. If it does not, say so to yourself before you say it to the customer.

Trace the price back to a passed cost. You should be able to show the old price, the passed cost, and the new price in a line.

Announce one clear change

Tell the customer in writing before the new price applies. Use a short line for the reason and a short line for the change. "Effective [date], our price for [service] is [new price] because fuel costs have risen. Your service and terms are unchanged." That is enough.

Fuel surcharges can work, but only if they are simple and tied to a fuel price you can show. If you cannot explain the surcharge in a short line, use a base price change. Do not follow the notice with apologies, market explanations, and requests for patience. A clear notice is more respectful than a long story.

The customer should know the new price, the date, and the reason. When they ask why, repeat the unit math: the job uses a certain amount of fuel, the fuel cost rose, and the price covers that passed cost. When they ask whether it is permanent, answer honestly. If you do not know, say you will review it when the fuel cost settles.
