Understanding gas station fuel margins
Fuel is famously low-margin. In 2025 the national average fuel gross margin ran about 40 cents per gallon, but after credit card fees and operating costs, net fuel profit is often just a few cents per gallon. That is why fuel is best understood as a traffic driver rather than a profit center.
The real money is inside
The convenience store is where stations make their margins. In-store items carry 20% to 40% gross margins, and the C-store typically generates roughly 70% of a station's profit from about 30% of its revenue. When you value or buy a station, inside sales and margin matter enormously.
