Business Lessons from Costco: What Leaders Can Learn From Its Success

Costco has built one of the most recognizable business models in modern retail by doing something that seems surprisingly simple: give members compelling value, keep operating costs under control, and give customers a reason to come back.

But beneath that simplicity is a remarkably disciplined business strategy.

Costco's model combines membership revenue, limited product selection, high sales volumes, private-label products, employee investment, supplier relationships, and a strong focus on customer value. The company has continued to grow without abandoning the fundamental principles that shaped its business.

In fiscal 2025, Costco generated $269.9 billion in net sales and $5.3 billion in membership-fee revenue. It ended the year with approximately 81 million paid members, while its U.S. and Canada renewal rate stood at 92.3% and its worldwide renewal rate was 89.8%.

Those numbers make Costco an interesting case study for more than retailers.

The company's approach offers lessons for entrepreneurs, managers, executives, and business owners about customer loyalty, employee development, operational discipline, leadership succession, pricing, and building a business model that reinforces itself.

The lesson isn't that every company should copy Costco.

It is that leaders should understand why Costco's individual decisions work together so effectively.

Understanding Costco's Business Model

Costco's strategy begins with its membership model.

Customers pay an annual fee for access to Costco's warehouses and products. That creates a different relationship from a conventional retailer, where the primary transaction occurs when the customer purchases a product.

Costco has an ongoing incentive to make membership valuable enough that customers want to renew.

That creates an unusual strategic dynamic.

The company isn't simply trying to maximize the margin on every individual product. It can focus on creating an overall perception of value that encourages customers to remain members.

Costco's financial results demonstrate how significant that membership model has become. Membership-fee revenue reached $5.323 billion in fiscal 2025, up from $4.828 billion the previous year.

At the same time, Costco deliberately operates with relatively low merchandise margins. Its fiscal 2025 gross margin was 11.12%.

That combination is important.

Costco doesn't simply sell products cheaply. It has built a business model in which membership, pricing, merchandise selection, purchasing scale, and customer loyalty reinforce one another.

Costco's Customer Value Proposition

Costco's mission is straightforward: provide members with quality goods and services at the lowest possible prices. Its code of ethics centers on obeying the law, taking care of members and employees, respecting suppliers, and ultimately rewarding shareholders.

This is more than corporate language.

The company's strategy is built around that proposition.

Customers have a financial reason to join Costco. They then have an ongoing reason to evaluate whether the membership continues to be worthwhile.

That creates an important business lesson:

A strong business model gives customers a reason to keep choosing you.

Why Costco's Membership Model Is So Powerful

Customer acquisition receives enormous attention in modern business.

Companies spend money on advertising, promotions, salespeople, discounts, and other tactics designed to attract new customers.

But Costco demonstrates the importance of another metric: retention.

At the end of fiscal 2025, Costco reported a 92.3% renewal rate in the United States and Canada and an 89.8% renewal rate worldwide.

A high renewal rate doesn't happen simply because customers are members.

Customers have to believe that the membership provides enough value to justify paying for another year.

For business leaders, the lesson extends well beyond membership businesses.

A subscription company, software provider, professional service firm, training company, or consulting business can ask the same question:

What makes customers want to stay?

Acquiring customers matters.

Creating customers who don't want to leave may matter even more.

Key Business Challenges Costco Has Solved

Costco operates in an industry where companies face several difficult challenges.

Retailers must manage:

• Price competition
• Labor costs
• Inventory
• Customer expectations
• Supplier relationships
• Store operations
• Product selection
• E-commerce
• Changing consumer behavior
• Expansion

Costco has responded by maintaining a relatively focused operating model.

Rather than trying to offer every possible product, Costco generally emphasizes a curated selection of merchandise that can be purchased in high volumes.

This creates purchasing power and operational efficiencies while giving customers a shopping experience built around discovery and value.

The model isn't without challenges.

Costco still has to invest in technology, e-commerce, new warehouses, employee compensation, supply chains, and international expansion.

The important lesson is that strategic discipline does not eliminate complexity; it helps organizations decide where complexity is worth accepting.

Lesson 1: Build Your Business Around Customer Value

One of Costco's clearest lessons is that customer value should be more than a marketing slogan.

It should influence business decisions.

Costco's membership model creates a direct connection between customer value and the company's recurring revenue.

If customers don't believe they are getting enough value, they have little reason to renew.

That creates accountability.

For other businesses, the same principle can be applied without a membership model.

Ask:

• Why do customers choose us?
• What problem are we solving?
• Is our value proposition clear?
• Are customers receiving measurable value?
• What would make them leave?
• What would make them recommend us?

A strong strategy doesn't simply answer the question "How do we sell more?"

It answers "Why should customers continue choosing us?"

Lesson 2: Don't Sacrifice Long-Term Value for Short-Term Margin

Costco's business model is particularly interesting because the company has historically operated with relatively low merchandise margins.

The objective isn't necessarily to maximize the profit on every individual product.

Instead, Costco seeks to create an attractive combination of merchandise value and membership economics.

Its 2025 gross margin was 11.12%, while membership-fee revenue reached $5.323 billion.

That illustrates an important strategic concept:

Profitability doesn't always come from maximizing the margin on every transaction.

Businesses can create stronger economics through:

• Recurring revenue
• Customer retention
• Volume
• Efficiency
• Cross-selling
• Lower acquisition costs
• Customer loyalty

Entrepreneurs should therefore look at the entire business model rather than optimizing one financial metric in isolation.

Lesson 3: Treat Employees as Part of the Business Strategy

Costco provides one of the stronger examples of employee investment as part of an operating strategy.

At the end of 2025, Costco employed approximately 341,000 people worldwide. The company reported that about 94% of its U.S. and Canadian employees who had been with Costco for at least one year were retained.

Costco explicitly states that it doesn't seek to minimize employee wages and benefits. Instead, the company says it believes maintaining compensation above industry averages for much of its workforce can help reduce turnover, increase productivity, and improve employee satisfaction.

Costco also identifies employee development and promotion from within as important elements of its workforce strategy. In 2025, approximately 7,500 hourly employees completed its six-week Supervisor in Training program in the United States and Canada.

This provides an important lesson for business leaders:

Employee development isn't necessarily separate from business performance.

Training, career development, retention, and leadership development can become part of the operating model.

That is particularly relevant for businesses trying to build a strong internal leadership pipeline.

Lesson 4: Develop Leaders From Within

Costco's leadership succession provides a particularly interesting case study.

Current CEO Ron Vachris is a Costco veteran with more than four decades at the company. Costco says he began his career as a forklift driver and subsequently served in major operational and merchandising roles before becoming president and CEO in January 2024.

That is a powerful example of internal leadership development.

It doesn't mean every organization should promote exclusively from within.

But it does demonstrate the potential value of building a pipeline of employees who understand the business from multiple perspectives.

An employee who has worked across operations, merchandising, management, and executive leadership may bring a different understanding of the organization than an external executive who has never worked inside it.

For business leaders, the takeaway is straightforward:

Don't wait until a leadership position becomes vacant to start developing its replacement.

Leadership pipelines should be built years in advance.

Lesson 5: Make Your Business Model Simple for Customers

Costco's operations are complex, but the customer proposition is relatively easy to understand.

Pay for membership.

Shop for products.

Receive value.

Return when you need more.

That simplicity matters.

Businesses often become more complicated as they grow. They add products, pricing tiers, services, features, policies, and processes.

Some complexity is necessary.

But customers shouldn't have to understand the organization's internal complexity to do business with it.

A useful leadership question is:

What can we simplify for the customer even if our internal operations are complicated?

The best businesses often make complicated systems feel simple.

Lesson 6: Curate Instead of Trying to Offer Everything

One of Costco's distinctive characteristics is its relatively limited product assortment compared with many large retailers.

That may seem counterintuitive in an era when businesses compete to offer more choices.

But more isn't always better.

Too much choice can create:

• Decision fatigue
• Higher inventory complexity
• Greater purchasing complexity
• More operational costs
• Less differentiation

Costco's approach is closer to curation.

The company selects products it believes will provide value to its members.

This creates another useful business lesson:

Customers don't necessarily need more choices. They need better choices.

That principle can apply to software, professional services, online courses, consulting, consumer products, and almost any other industry.

Lesson 7: Build a Brand Around Trust

Costco's value proposition depends heavily on trust.

Members expect the company to offer good products at competitive prices.

That trust becomes particularly important when customers encounter products they didn't specifically plan to buy.

Costco's Kirkland Signature private-label brand is an important part of that strategy.

A strong private-label business can give a company greater control over:

• Product specifications
• Quality
• Pricing
• Differentiation
• Customer experience

The broader lesson is that brands become more powerful when customers know what they can expect.

Consistency creates confidence.

Confidence creates trust.

And trust can create loyalty.

Lesson 8: Operational Efficiency Should Support the Customer Experience

Costco is known for an operating model built around volume, limited selection, warehouse efficiency, and disciplined purchasing.

But efficiency isn't valuable simply because it lowers costs.

It becomes strategically valuable when the savings can support the customer proposition.

That's an important distinction.

A company can cut costs in ways that damage service, quality, or employee performance.

Costco's model illustrates a different approach:

Find efficiencies that strengthen the value proposition.

For business leaders, every cost reduction should therefore be evaluated with two questions:

1. How much money does this save?
2. What does it do to the customer and employee experience?

The cheapest operating model isn't necessarily the strongest.

The strongest model is one where efficiency and value reinforce one another.

Lesson 9: Think About Suppliers as Strategic Partners

Costco's code of ethics specifically includes respecting suppliers.

That's important because suppliers aren't simply a source of inventory.

They can influence:

• Product quality
• Availability
• Innovation
• Pricing
• Reliability
• Brand reputation

Costco's supplier expectations also extend to human rights and working conditions through its supplier Code of Conduct.

For other businesses, the lesson is that supplier relationships should be managed strategically.

A business that constantly treats suppliers as adversaries may achieve short-term savings but damage long-term relationships.

Strong businesses often create value throughout their ecosystem rather than extracting value from every participant.

Lesson 10: Protect the Core While Continuing to Grow

Costco continues to expand.

In fiscal 2025, it opened 27 new warehouses, including relocations, for 24 net new warehouses. Net sales increased 8% to $269.9 billion.

But growth hasn't required Costco to abandon its fundamental business model.

This is an important lesson for entrepreneurs.

Growth creates pressure to change everything.

New customers want different things. Investors may demand expansion. Competitors change. Technology evolves.

Yet some aspects of a business are worth protecting.

Leaders should distinguish between:

What must change to support growth

and

What makes the company valuable in the first place.

That distinction can prevent growth from destroying the very characteristics that made the company successful.

A Costco Case Study in Long-Term Thinking

Costco's business model is particularly interesting because many of its strategies reinforce one another.

Consider the chain:

Low prices

↓

Strong perceived value

↓

Membership renewals

↓

Recurring membership revenue

↓

Customer loyalty

↓

High purchasing volume

↓

Supplier relationships and operating efficiency

↓

Ability to maintain value

The same system also connects employees to the model:

Competitive compensation and development

↓

Employee retention

↓

Experienced workforce

↓

Operational consistency

↓

Productivity and customer experience

This is what makes Costco such a useful business case study.

Its success isn't based on one clever tactic.

It is based on a system of mutually reinforcing decisions.

What Business Leaders Can Learn From Costco

The Costco case provides several principles that can apply far beyond retail.

Why Costco's Strategy Still Matters

Costco isn't successful because every business should operate like a warehouse club.

Its value as a case study comes from something more fundamental.

The company demonstrates what can happen when strategy, culture, operations, employees, customers, and financial incentives point in the same direction.

That is increasingly difficult for organizations to achieve.

Companies often create one strategy for customers, another for employees, another for investors, and another for operations.

Costco offers a different model.

Its mission explicitly connects members, employees, suppliers, legal and ethical responsibilities, and shareholders.

That doesn't mean Costco is perfect or that every element of its model will work elsewhere.

It means the company provides a useful example of strategic alignment.

The Bigger Business Lesson From Costco

Perhaps the most important lesson from Costco is that a successful business doesn't necessarily need to chase every trend.

It needs to understand its customers, establish a compelling value proposition, build a business model that supports that proposition, and execute consistently.

Costco has changed over time. It has expanded internationally, invested in technology and e-commerce, opened new warehouses, adjusted membership pricing, and expanded its product and service offerings.

But the underlying proposition has remained remarkably consistent.

Give members value.

Take care of employees.

Build strong supplier relationships.

Operate efficiently.

Develop leaders.

And protect the trust that keeps customers coming back.

For entrepreneurs and business leaders, that may be the most useful lesson of all.

Sustainable growth often comes from doing a few important things exceptionally well—and making sure the entire organization supports them.
