Warehouse Club U.S. and Canada Membership Renewal Rate measures the percentage of eligible memberships renewed under Costco's trailing renewal methodology.

Costco reported a 92.2% U.S. and Canada renewal rate at the end of Q3 FY2026.

The denominator matters

Costco excludes affiliates of Business members and uses a trailing calculation based on renewals during a defined historical window rather than simply dividing current renewals by current expirations.

Investor caution

Renewal rates can shift with mix. Costco said a higher share of memberships sold online, including through digital promotions, pressured the reported renewal rate because those memberships renew at a slightly lower rate on average.

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.
