Warehouse Club Shopping Frequency Growth measures the year-over-year change in how often members shop within the comparable-sales base.

Costco said shopping frequency increased approximately 2% in Q3 FY2026 and 3% over the first 36 weeks.

The comparable-sales bridge

Costco explains comparable sales growth through two core drivers: shopping frequency and average ticket.

Higher frequency means more member visits. Higher ticket means more spending per visit. Both can lift comparable sales, but they reflect different customer behavior.

Investor caution

Shopping frequency is an issuer-defined operating metric, not the same as total transaction count or unique customer growth. Changes in membership mix and digital shopping can affect interpretation.

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.
