Subject: A temporary fuel surcharge starting [date]

Hi [Customer name],

Fuel prices have risen sharply this year, and fuel is one of the largest costs of every [job/visit/delivery] we do for you. Rather than raise our base prices, we're adding a temporary fuel surcharge of $[amount] per [job] starting [date].

The surcharge covers only our added fuel cost, nothing more. We'll review it every [month] against the U.S. average diesel price and reduce or remove it when fuel comes back down.

Thank you for your business. If you have any questions, just reply to this email.

Subject: An update to our pricing from [date]

Hi [Customer name],

Over the past [months], our operating costs, especially fuel, have risen significantly. We've absorbed as much as we can, but to keep providing the same level of service we're adjusting our prices by [x]% (about $[amount] per [job]) starting [date].

We don't make this change lightly. The new price reflects our higher costs, and we've kept it to the minimum needed to cover them.

Your service won't change in any other way. If you'd like to talk it through, just reply or call us at [phone].

Thank you for being a customer,
[Your name]
[Company]

(FAQ)

Telling customers about a surcharge

01How do I tell customers about a fuel surcharge?

Give written notice before it starts, explain that it covers fuel only, state the amount, and say when you'll review or remove it. Customers accept surcharges more readily when they're specific, temporary, and tied to a public price.

02How much notice should I give?

At least one billing cycle for recurring customers, or whatever your contract requires. Some contracts specify 30 days. New bookings can see the surcharge at the time of quote.

03Should I use a surcharge or a price increase?

A surcharge is easy to remove when fuel falls and shows customers exactly what changed. A price increase is simpler if the higher cost looks permanent. The calculator shows both numbers.

04How do I work out the surcharge amount?

Multiply the increase in price per gallon by the gallons you use per month, then divide by the jobs you do per month. The free calculator does this for you and also shows it as a percentage.

05Are these templates legal advice?

No. They're starting points. Check your contracts, local rules, and any industry regulations (for example on moving or Medicaid transportation) before sending.
