How Costco Turned Membership Fees Into a Business Empire

Most retailers spend heavily trying to convince people to enter their stores.

Costco does something far more unusual: it asks customers to pay for the privilege.

At first, the idea sounds backwards. Why would anyone pay an annual fee just to walk into a warehouse filled with oversized packages, concrete floors, industrial shelves, and limited product choices?

The answer is that Costco is not really selling access to a store. It is selling the belief that becoming a member will save more money than the membership costs.

Once customers accept that promise, the entire business begins to work differently.

The Membership Fee Changes the Relationship

A standard Costco membership in the United States costs $65 per year, while an Executive membership costs $130. The Executive tier includes a 2% reward on qualifying purchases, subject to an annual limit.

That annual payment may seem small compared with the amount members spend on groceries, appliances, gasoline, electronics, and household products. Across millions of customers, however, those fees become a remarkably dependable source of revenue.

Costco ended fiscal 2025 with approximately 81 million paid members and 145.2 million total cardholders. Membership fee revenue reached $5.32 billion, an increase of 10% from the previous year.

Unlike the profit on a television or a package of steaks, membership revenue does not depend on selling another physical product every time.

It arrives because customers decide that access itself remains valuable.

Low Prices Are Part of the Contract

Costco’s membership model works because the company gives members a reason to renew.

The fee creates an unspoken contract: customers pay Costco upfront, and Costco is expected to reward them with dependable value throughout the year.

This allows the company to operate with lower merchandise margins than many traditional retailers. Costco buys enormous quantities, limits the number of products it carries, uses simple warehouse layouts, and moves inventory quickly.

A typical warehouse carries fewer than 4,000 active items in its core business. A large supermarket or general retailer may offer far more choices, but Costco is deliberately selective.

The limited selection gives the company greater purchasing power. Instead of dividing orders among dozens of similar brands, it can negotiate enormous volumes on a smaller number of products.

The warehouse may look simple, but that simplicity is doing real financial work.

Pallet displays reduce handling. Basic interiors lower operating costs. Large packages increase the value of each transaction. Fast inventory turnover means products spend less time sitting on shelves.

Costco is not trying to create the most elegant shopping experience. It is trying to make members feel that almost every visible dollar is going into the product rather than the decoration around it.

Membership Revenue Makes Patience Possible

Traditional retailers often need larger markups because merchandise sales must cover nearly every part of the business.

Costco has another financial engine.

Membership fees help offset operating costs, which gives the company more room to keep product prices competitive. Costco openly describes this as one of the reasons it charges members in the first place.

That does not mean the warehouses could survive without selling products. Costco generated nearly $270 billion in net sales during fiscal 2025, so the retail operation remains enormous.

The important difference is that membership revenue reduces the pressure to squeeze the maximum possible profit from every item.

This is where Costco’s model becomes difficult for competitors to copy.

A retailer can lower its prices for a promotion. Costco has built an entire system in which lower prices help protect renewals, and renewals produce recurring revenue that supports the system.

The discount is not merely a marketing campaign. It is part of the economic structure.

Renewals Are More Valuable Than Constant Acquisition

Many subscription businesses appear attractive until customers begin leaving.

Costco has largely avoided that problem.

At the end of fiscal 2025, its membership renewal rate was 92.3% in the United States and Canada and 89.8% worldwide.

Those numbers reveal something more important than customer satisfaction. They show habit.

Once someone begins buying groceries, filling the car with gasoline, ordering eyeglasses, or purchasing household products at Costco, the membership becomes connected to an established routine.

The customer has already paid the fee. That creates a natural reason to return and receive more value from it.

Each visit makes renewal feel easier to justify. Each renewal makes another year of visits more likely.

This is a powerful cycle because keeping an existing member is usually more predictable than persuading a completely new customer to join.

Costco does not need every shopping trip to be perfect. It needs the overall relationship to feel worthwhile by the time the renewal notice arrives.

Executive Memberships Deepen the Commitment

The Executive membership takes the same idea one step further.

Members pay an additional $65 per year but can earn a 2% reward on eligible purchases. For customers who spend enough, the reward can cover much or all of the upgrade cost.

The arrangement encourages a simple thought: since the customer already has the premium membership, more purchases should go through Costco.

Executive members represented 38.7 million of Costco’s paid members at the end of fiscal 2025. More importantly, they accounted for approximately 73.6% of worldwide net sales.

That is not an accidental detail.

The Executive tier identifies Costco’s most engaged customers and gives them another reason to consolidate their spending inside the company’s ecosystem.

A member may join for cheaper groceries and eventually use Costco for fuel, travel, tires, furniture, insurance-related services, or a major appliance.

The annual fee opens the relationship. The wider collection of services makes it harder to replace.

The Warehouse Creates a Sense of Discovery

Costco’s appeal is not based entirely on predictable savings.

Part of the experience comes from not knowing exactly what will be available.

The company carries everyday essentials, but it also rotates clothing, electronics, furniture, seasonal products, luxury items, and unexpected deals. Shoppers may enter for paper towels and leave discussing a kayak, a watch, or a surprisingly affordable vacation package.

This “treasure hunt” effect gives the warehouse a personality that a normal discount store often lacks.

Limited availability also changes customer behavior. When a product may disappear, postponing the purchase feels risky.

Costco manages to combine routine and surprise: members know they can find familiar necessities, but they also expect to discover something they were not planning to buy.

That balance keeps a highly efficient warehouse from feeling completely predictable.

Trust Became Costco’s Real Product

Membership fees work only when customers trust the company behind them.

If members begin believing that prices are no longer competitive, product quality is declining, or the annual fee is no longer justified, the model weakens quickly.

Costco therefore has a reason to protect its reputation beyond a single transaction.

Its Kirkland Signature private label plays an important role. A strong private brand gives Costco more control over quality and pricing while offering products customers cannot directly purchase from another retailer.

The famous food court prices, generous return practices, fuel discounts, and carefully selected products also reinforce the same message: the membership is supposed to return value to the person paying for it.

Some of these decisions may sacrifice a little profit today. They help protect something more valuable—the customer’s willingness to renew next year.

The Empire Continues to Compound

Costco’s membership engine is still expanding.

During the first 36 weeks of fiscal 2026, the company generated approximately $4.06 billion in membership fees, compared with $3.60 billion during the same period a year earlier. Net sales reached $203.37 billion over those 36 weeks.

More members produce more fees. More fees support competitive prices and expansion. Competitive prices attract more shoppers, while higher sales volumes strengthen Costco’s negotiating position with suppliers.

The larger the system becomes, the harder it is to reproduce.

A new competitor cannot simply introduce a membership card and expect the same result. It would need strong supplier relationships, enormous purchasing volume, efficient distribution, trusted private-label products, and enough customer loyalty to make the annual fee feel obvious rather than irritating.

Costco spent decades building those pieces together.

The Fee Was Never Just a Fee

Costco’s real achievement was not discovering that customers would pay $65 or $130 per year.

It was creating a business where millions of people feel uncomfortable shopping without having paid it.

The membership fee provides recurring revenue, but its deeper value is behavioral. It turns occasional shoppers into members, members into repeat customers, and repeat customers into people who organize part of their household spending around Costco.

Plenty of businesses charge subscriptions. Far fewer create enough trust that customers happily renew before knowing exactly what they will buy next.

Costco built its empire by understanding that the strongest retail relationship does not begin at the checkout counter.

It begins when the customer decides that belonging is worth paying for.
