Revenue Model & Pricing
Costco runs a membership warehouse club: shoppers pay an annual fee ($65 for Gold Star or Business, $130 for Executive in the U.S. and Canada since September 2024) to buy from a tightly edited assortment of roughly 4,000 items. Limited choice means huge volume per item, which gives Costco strong buying power with suppliers. Costco caps markups at about 14% on branded goods and 15% on Kirkland Signature, so merchandise earns thin margins and membership fees ($5.9B in FY2026) supply much of the profit. Gas stations, pharmacy, optical, hearing aids, tires and Costco Travel bring members back more often, and Kirkland Signature lets Costco set a quality and price benchmark against national brands.

Growth Strategy
Costco grows mostly by itself rather than through acquisitions. It opened 28 warehouses in FY2026 (25 net new) and plans 33 in FY2027, while pushing members to upgrade to Executive, which raises fee income and spending per household. Digital is the fastest-growing channel: digitally enabled sales topped $33B in FY2026 with site and app traffic up about 30%. Costco also leans on ancillary businesses (gas, pharmacy, travel) that grew faster than the core in FY2026, and on supply-chain investments such as its Nebraska poultry complex and Costco Logistics for bulky items.
How Costco Makes Money: FAQ
How does Costco Wholesale generate operating profit from its membership model?
Costco sells goods at markups of about 14-15% and earns much of its operating profit from annual membership fees, which were $5.907B in FY2026. Because fees cost little to collect, they fund low prices that keep members renewing.
What is Costco's strict maximum gross margin markup policy?
Costco enforces a strict corporate pricing rule that caps gross markups at a maximum of 14% on branded goods and 15% on Kirkland Signature items (compared to 25% to 50%+ markups at traditional department stores and supermarkets). Whenever Costco secures lower supplier costs, it passes the savings directly to members.
How does Costco's Executive Membership tier drive retail sales?
Executive members pay $130 a year and earn a 2% reward of up to $1,250. Costco had 42.3 million paid Executive members at the end of FY2026, about half of its 84.1 million paid members, and they account for most of its sales.
What ancillary businesses operate inside Costco warehouses?
Costco warehouses feature high-margin, foot-traffic-driving ancillary businesses: low-cost Costco Gas stations, tire installation centers, optical vision exams and eyewear, full-service pharmacies, hearing aid centers, Costco Travel booking services, and the famous Costco Food Court.
How does Costco optimize supply chain logistics and pallet cross-docking?
Costco operates a high-velocity cross-dock logistics network. Full truckloads of goods arrive at centralized depots, are immediately sorted without long-term warehousing, and shipped to warehouses on standardized wooden pallets that are rolled directly onto retail sales floors with forklifts, eliminating unpacking labor.
What is the 'Treasure Hunt' shopping experience at Costco?
Costco designs its warehouse layout without aisle signs and intentionally rotates high-end luxury items (designer handbags, fine jewelry, seasonal patio sets, electronics, specialty wines) alongside grocery staples. This creates an exciting 'treasure hunt' atmosphere that drives impulse purchases and frequent visits.
How does Costco handle inventory turnover and negative working capital?
Costco sells inventory so rapidly (turning inventory over 12 to 13 times per year) that it often sells goods to members and collects cash before it is required to pay suppliers under standard 30-day invoice terms, creating a highly advantageous negative working capital cycle.
How does Costco monetize e-commerce and digital grocery delivery?
Costco sells online through Costco.com and its app (including big-ticket items, appliances and gold bars), Costco Next (direct-from-supplier shopping) and same-day delivery through Instacart. Digitally enabled sales topped $33B in FY2026, up more than 20%.
Does Costco make money selling products?
Barely. Costco aggressively caps its profit margins on goods at roughly 14%. The company sells products almost at cost to drive massive foot traffic, generating the vast majority of its billions in pure net income entirely from the $60-$120 annual membership fees.
