Fuel pricing and margins: what cents per gallon really means

Every driver who passes your sign sees your price. Few business decisions are that public, and few are made with less information. Good pricing is not about being cheapest. It is about knowing exactly what each price change does to your margin and your volume.

Start with the right cost

Your fuel margin is the pump price minus what that gallon actually cost you. The cost side is where owners most often fool themselves.

• Use your last received cost, not what you think you paid. Costs move between deliveries.
• Include what rides on each gallon: taxes that are not already in your invoice price, freight if billed separately, and any per-gallon fees in your supply agreement.
• Remember card fees. A percentage-based card fee grows as the price grows. On a card sale, part of your cents-per-gallon margin goes straight to the processor. Know your effective card rate.

A simple way to frame it: net margin per gallon is pump price, minus delivered cost, minus the card fee on that gallon.

Margin over time, not per day

Wholesale prices rise and fall. Retail prices tend to follow upward quickly and drift down more slowly. Over a full cycle, many operators earn most of their fuel margin while costs are falling and give some back while costs are rising. That means:

• Judging a price by one day's margin is misleading. Look at margin per gallon across a week and a month.
• A temporarily thin margin while costs rise can be the right decision if it protects volume.
• Holding price for a few days as costs fall is often where the month is made.

Watching competitors without chasing them

Know the stations your customers actually compare you with. That is usually a few sites on the same route, not every station in town. For each one, note brand, amenities and whether they are a price leader or a follower.

Then decide your position deliberately. Matching the cheapest site may not pay if your store, location or brand already earns a premium. Being a few cents higher can be fine; being the most expensive on the corner usually is not.

The store pays for the pumps

Fuel brings people to the lot. The store is often where the margin is. A price that drives an extra car a day matters more if those drivers walk inside. When you evaluate a fuel price change, look at in-store transactions alongside gallons.

Questions to answer before every change

1. What did my last load cost, delivered?
2. What will my margin per gallon be at the new price, after card fees?
3. Which competitors will notice, and what will they likely do?
4. What happened to volume the last time I made a similar move?

If you cannot answer the first two quickly, the problem is not pricing. It is the back office. The WRK Fuels portal shows last received fuel price by product, and our consulting work includes building a pricing routine that fits your market.
