Warehouse Club Total Cardholders count people holding membership cards across paid memberships and associated household cards.

Costco reported 148.5 million total cardholders at the end of Q3 FY2026, compared with 142.8 million a year earlier.

Why it matters

Cardholders indicate the breadth of people who can shop under the membership system, while paid members represent the fee-paying membership base.

The two measures therefore answer different questions about reach and monetization.

Investor caution

Do not divide membership fee revenue by total cardholders to infer an average membership fee. Many cardholders belong to the same paid membership.

Part of the Warehouse Club Economics

Connect membership monetization and retention, mature-base comparable sales, digital demand, and physical footprint expansion for warehouse-club retailers.

How the model fits together
  • Membership base, retention, and fee revenue: Paid members and cardholders describe different parts of the membership base, renewal rates measure retained eligible memberships under Costco's trailing methodology, and membership fee revenue grows through sign-ups, fee changes, and Executive upgrades rather than member count alone.
  • Comparable sales, traffic, ticket, and digital demand: Comparable sales cover mature warehouses and digitally enabled businesses, while shopping frequency and average ticket are the two core behavioral drivers. Adjusted comparable sales remove gasoline-price and foreign-exchange effects, and digitally enabled comparable sales use digital initiation rather than fulfillment channel.
  • Net sales and footprint expansion: Net sales combine the mature comparable base with sales from newer warehouses. Warehouse count and net-new warehouse contribution add physical-capacity context, while net sales growth can also be affected by gasoline prices, foreign exchange, and business mix.
