Convenience store fuel margin per gallon measures retail fuel revenue less fuel cost of goods sold per gallon under Casey's convention.
Casey's reported 42.57 cents per gallon in fiscal 2026, up from 38.68 cents in fiscal 2025.
Unit contribution increased by 3.89 cents per gallon
The increase was approximately 10.1%.
That gain combined with 10.0% growth in total gallons to produce a much larger increase in fuel gross-profit dollars.
The annual fuel contribution bridge reaches about $1.496 billion
Multiplying 3.515 billion gallons by $0.4257 gives approximately $1.496 billion.
Casey's reported $1.497 billion of retail fuel revenue less cost of goods sold, confirming the unit metric against the category total.
