Protect Your Margin When Fuel Costs Spike

When diesel jumps, your delivery fee may no longer cover the stop. The U.S. national average diesel price was at a record $6.06 per gallon on a Friday, more than 60% above $3.71 a year earlier. The earlier record was $5.82 per gallon in June 2022.

In the U.S., diesel is used in many freight and delivery networks, so higher diesel prices raise the cost of moving goods. Diesel also powers trucks and railroads that transport goods, so a sharp rise may ripple through the economy as businesses raise prices to cover energy costs. If you sell food, the exposure can be large: fuel represents about 15% to 30% of what food costs overall.

Recalculate the delivery stop before you reprice

A fuel spike does not mean every product price should rise. The cost of a delivery stop may have changed. When your delivery cost goes up but your fee stays flat, each stop reduces margin.

Start with the number you can test quickly: the cost to deliver a typical order. Use your current fuel price, your vehicle's miles per gallon, and the distance for a typical stop. Add any fixed delivery costs you already know, such as driver time, vehicle wear, or parking. Do not guess. Use the number from your last fuel fill-up and your last delivery route. This number shows how much one stop costs before you change a fee.

Then compare that number to what you charge. A fee that covers the old cost but not the new one leaves a difference. That difference is where margin is lost. You can close it with a delivery fee, a minimum order, or a delivery-range price bump. Pick one lever first. Using all of them at once can make the change feel larger to customers than it needs to be.

Use one lever, not all three at once

Keep this checklist. Each item is small enough to test before you send a quote, and each item protects a different part of the delivery cost.

• Recalculate per-mile delivery cost with current fuel price, vehicle miles per gallon, and a typical stop distance.
• Delivery fee: add or adjust a fee that covers the new per-mile cost for a standard delivery.
• Minimum order for delivery: raise the order size needed before you deliver, so low orders stop consuming the fee.
• Range price bump: charge more for farther stops, where fuel and driver time rise fastest.
• Supplier pass-through: write the question, Is fuel or freight cost being passed through to my quote?

The delivery fee is the most direct lever. It follows the customer's order and makes the extra cost clear. The minimum order protects you from small orders that look profitable until you count the stop. The range price bump protects you from long stops that use more fuel and more time.

Do not hide the change inside product prices. A customer who buys a single item and pays a delivery fee can see why the cost changed. A general product price increase may look like a broad price rise. Passing through costs to customers is easier when the charge is called a delivery fee. Keep the delivery cost in the delivery charge.

Ask suppliers whether freight is already in your quote

Some of your input costs may already include fuel. A supplier who delivers to you may include truck fuel costs, freight, or logistics in their quote, so a freight cost increase may already be inside your quote. Raising your delivery fee while a supplier also raises product price for the same fuel spike can mean paying for the same cost again.

A temporary fuel surcharge is a way to separate energy costs from product prices. In April, Amazon charged some third-party sellers a temporary 3.5% fee for fuel and logistics. You do not have to copy it. Fuel can be treated as a separate cost. A separate cost keeps the product price from carrying a fuel spike.

Ask the supplier question: Is fuel or freight cost being passed through to my quote? A yes answer should include how much of the supplier price increase is fuel and how much is another cost. A no answer should say whether their quote will change when fuel moves. You need a clear answer before you set your own delivery price.
