Warehouse Club Net Sales are sales from merchandise and ancillary businesses before membership-fee revenue.

Costco reported $69.154 billion of net sales in Q3 FY2026, up from $61.965 billion a year earlier.

What drives it

Costco says net sales growth comes primarily from comparable sales and sales from newly opened warehouses. Core merchandise, gasoline, pharmacy, digital commerce, business centers, and other ancillary businesses all contribute.

Membership fees are reported separately, so net sales should not be confused with total revenue.

Investor caution

Net sales can be affected by gasoline prices and foreign exchange, which may materially change reported growth without reflecting underlying traffic or ticket trends.

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.
