A fuel jobber makes a few cents on a gallon and a good living on millions of gallons. That one sentence captures the whole business: thin margins, big volume, and a handful of extra income streams that smooth out the ride. This is how the money comes together, and why the back office matters so much to it.
The core: the gallon spread
A jobber buys fuel in bulk at the rack and resells it for a small markup. The profit on any single gallon is slim, often a few cents, but the volume is enormous, so the pennies stack into real money. That is why a jobber is a high-volume, low-margin business. For the basics of the role, see what is a fuel jobber.
The extras that matter
The gallon spread is thin and it moves with the market, so jobbers round out their income:
- Freight and fees. Charges for delivery and hauling.
- Branded incentives. Programs and support tied to branded supply.
- Cardlock and fleet fueling. Recurring commercial fuel business.
- Commissioned-agent sites. Supplying and settling stations run on commission.
- Company-owned c-stores. Inside-store margin on top of fuel.
Why volume rules everything
When margin per gallon is small, total profit hinges on gallons moved. More volume at the same margin scales the profit directly, and a fraction of a cent of slippage across millions of gallons is a serious number. That arithmetic is why jobbers chase volume and protect every sliver of margin.
Where the profit leaks
On a thin-margin, high-volume business, small leaks scale fast: pricing on stale cost, fuel shrink and loss, double entry and billing errors, and cash tied up in slow receivables. The profit the volume earns can drain out through any of them. Guarding it is mostly about tight cost tracking, reconciliation, and clean billing.

This is exactly what a fuel back office is for. FastDragon Fuel Jobber keeps cost and margin accurate, ties out the fuel, and removes the double entry that eats thin-margin profit, so the volume you move actually reaches the bottom line.
Quick answers
What is a typical jobber margin per gallon?
Independent industry write-ups commonly put a fuel distributor's margin around 3 to 6 cents per gallon, with broader estimates running 5 to 15 cents once freight and services fold in. The figure moves with the market and the contract, so confirm current numbers for your region before planning on one. For scale: at 10 million gallons a year, every cent of margin is worth $100,000.
Do jobbers lose money when fuel prices fall?
They can, on whatever fuel they own when the market drops. A jobber holding gallons in bulk storage rides the price down, which is why many run back-to-back: the load is sold before or as it is lifted, so little inventory sits exposed. A falling market can also widen the spread for a while, since street prices tend to come down slower than rack cost.
How does volume change the math for a jobber?
Gallons moved set the ceiling on profit. At a 4-cent spread, 5 million gallons a year earns $200,000 of gross fuel margin while 20 million earns $800,000, and much of the cost structure is shared between those two operations. That is why jobbers fight for dealer accounts, fleet contracts, and supply points that add steady gallons.
How do jobbers protect margin when rack prices change daily?
By pricing off the current rack instead of yesterday's. Rack prices reset every day, so a jobber selling today's loads against yesterday's cost gives margin away whenever the market jumps. Most automate the loop: pull the day's rack, apply the contract differential and taxes, and reprice every customer before the trucks load.
