Convenience store inside margin measures inside-store revenue less related cost of goods sold as a percentage of inside sales.

Casey's fiscal 2026 inside sales were about $6.340 billion and inside gross profit was about $2.676 billion.

The blended inside margin was about 42.2%

Dividing $2.676 billion by $6.340 billion gives approximately 42.2%.

The result sits between the prepared-food margin of 58.6% and grocery and merchandise margin of 35.8%.

Category mix determines the blended result

Prepared food represented about 28.0% of inside sales but roughly 38.9% of inside gross profit.

That higher gross-profit contribution reflects its substantially stronger category margin.

Use Convenience Store Prepared Food Margin and Convenience Store Grocery and Merchandise Margin to decompose the blend.

This is not a separately standardized GAAP line item

The calculation combines Casey's disclosed categories and excludes depreciation and amortization from category cost of goods sold.

It should not be compared mechanically with another retailer's consolidated gross margin.

Inside sales combine grocery and general merchandise with prepared food and dispensed beverages. Category sales and category contribution margins determine how mix shifts change the economics of the inside-store basket.

Fuel throughput and per-gallon economics
Retail fuel economics depend on physical gallons and contribution per gallon. Average gallons per mature store and same-store gallon growth help separate unit productivity from footprint expansion.

Mature-store demand, unit productivity, and footprint
Same-store category growth shows demand within the mature base, while average sales and operating income show unit productivity and store count captures expansion of the network itself.
