Warehouse Club Comparable Sales Growth measures net sales growth from warehouses and digitally enabled businesses operating for more than one year.

Costco reported 10% total-company comparable sales growth in Q3 FY2026.

Costco's scope

The comparable base includes remodels, relocations, expansions, and digitally enabled businesses that meet the more-than-one-year operating threshold.

Comparable sales are supplemental operating information rather than GAAP net sales.

Investor caution

Reported comparable sales can be materially affected by gasoline prices and foreign exchange. Use adjusted comparable sales when analyzing underlying shopping behavior.

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.
