Direct Answer
Costco reports revenue across 5 product and service lines in its fiscal 2025 Form 10-K. Food and Sundries is the largest, with $110 billion of revenue (40% of the total), followed by Non Foods at $71.2 billion (26%).
How Does Costco Make Money?
No single line supplies a majority of revenue: the largest, Food and Sundries, is 40%, which spreads Costco's exposure across several demand drivers. Between fiscal 2024 and 2025, Non Foods grew fastest (+11.3%) and Other slowest (+2.4%), so the revenue mix tilts toward Non Foods while that gap lasts.
| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Food and Sundries | $110 billion | $101 billion | 39.8% | 8.0% |
| Non Foods | $71.2 billion | $64.0 billion | 25.9% | 11.3% |
| Other | $51.2 billion | $50.0 billion | 18.6% | 2.4% |
| Fresh Food | $38.0 billion | $34.2 billion | 13.8% | 11.0% |
| Membership | $5.3 billion | $4.8 billion | 1.9% | 10.3% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Costco's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Costco reported in the segment note and revenue disclosures of its Form 10-K filed October 8, 2025 (accession 0000909832-25-000101), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
