How Costco Makes Money
Costco combines large-scale merchandise sales with recurring membership fees. The membership model strengthens recurring revenue and retention, while high sales volume, limited assortment, rapid inventory turnover, and efficient distribution support its low-cost operating structure.
Revenue Streams

Membership fees provide recurring annual revenue
Ancillary services such as gasoline, pharmacy, optical, tires, food court, and travel increase member utility and transaction frequency
E-commerce and digitally enabled sales extend member access beyond warehouse visits

Recurring Revenue
At Q3 FY2026, Costco reported:
82.9 million paid members
148.5 million cardholders
92.2% renewal rate in the U.S./Canada
89.7% worldwide renewal rate
Customer Acquisition
Costco does not publicly disclose a complete channel-by-channel acquisition funnel or customer acquisition cost. Supported growth drivers include new member sign-ups, new warehouse openings, digital membership promotions, comparable-sales growth, and e-commerce growth.
Customer Retention
Annual paid membership creates a recurring customer relationship
Consistent value supports renewals
Executive rewards strengthen retention for higher-spending members
Ancillary services create more reasons to use the membership
Kirkland Signature provides exclusive value
Scalability
The model scales because new locations can reuse the same membership architecture, limited-assortment buying discipline, warehouse format, distribution practices, and operating standards.
Scale90 Takeaway
Recurring revenue works best when tied to clear ongoing customer value. Costco’s scalability comes from combining membership economics with simplified operations, repeatable systems, and strong retention.
