Costco’s Gas Pricing Strategy: A Tactic as Unique as Its Rotisserie Chickens

How Costco sells such cheap gas – For the first time in its half-century of operation, Costco is experiencing an unprecedented surge in gas demand. The company’s stations have been inundated with customers, prompting them to deploy tanker trucks multiple times daily to prevent shortages. This week, during its quarterly earnings call, Costco highlighted the strain on its gas operations, noting that many customers are now buying only enough to fill their tanks—driven by anxiety over potential price hikes. Despite this, Costco has positioned itself as a go-to destination for affordable fuel, though its advantages are relative. The chain routinely offers gas at a discount of approximately 30 cents per gallon compared to local stations, a practice that has become increasingly appealing as prices climb above $4 nationally and surpass $6 on the West Coast.

The Economics Behind Costco’s Low Prices

Costco’s ability to undercut competitors hinges on its vast scale and membership-driven model. While most gas stations operate as small, independent entities with additional retail spaces or service centers, Costco leverages its massive infrastructure and loyal customer base to minimize costs. The company’s profit margin on gas is minimal—just a few cents per gallon—compared to the 25- to 35-cent markup typical of traditional stations. This pricing strategy allows Costco to absorb fluctuations in gas prices while still maintaining profitability. However, it comes with trade-offs: when fuel is inexpensive, long lines at stations can deter some buyers. Yet, the current demand suggests this challenge is being overcome.

Costco’s approach to gas is mirrored in its broader retail strategy. Products are often sold at or slightly above cost, with exceptions like its iconic $1.50 hot dog and soda combo. This model extends to gas, where the company’s low prices are part of a larger effort to attract and retain members. The result is a unique dynamic: as gas prices rise, Costco’s sales increase, but the company’s profit margins are squeezed. Conversely, when prices fall, the opposite occurs. Last year, during periods of low gas prices, the product contributed just 0.1 percentage point to Costco’s gross margin. In the most recent quarter, it subtracted 0.2 percentage points. Despite this, the company views the situation as a positive, as it helps build customer loyalty and reinforces its value proposition.

The Chicken Connection: A Strategic Marketing Move

While the cost of gas is a key factor, Costco’s success in this market also relies on a clever secondary strategy: its rotisserie chickens. These affordable, high-quality meals—priced at $4.99—are among the company’s most popular items, often drawing customers into the warehouse. This week, Costco revealed that a significant portion of its gas buyers also visit the stores, with foot traffic rising by 5% over the past three months. The connection between gas and chicken sales is clear: customers who fill up at stations are more likely to spend additional money in the warehouse, especially when they’re motivated by low prices.

Costco’s marketing team has capitalized on this trend, offering discounts on meat and eggs to further incentivize in-store purchases. The decision aligns with the company’s long-term goal of strengthening member engagement. “We saw it as an opportunity, recognizing that our members were dealing with higher gas prices, to really invest in increasing value,” said Gary Millerchip, Costco’s chief financial officer, during the earnings call. The idea is that by keeping gas prices low, Costco encourages members to visit more frequently, where they are more likely to buy other products. This strategy has proven effective, as the company reported that gas sales accounted for 10% of total revenue last year, with 747 stations contributing to that figure.

Costco’s CEO, Roland Vachris, emphasized the importance of gas in driving customer behavior. “We believe this will drive even greater loyalty with these members in the future,” he stated during the call, where the topic of gas was mentioned 72 times. The CEO noted that customers were stretched during the past quarter, allocating a larger share of their income to fuel. This financial pressure has created a window for Costco to highlight its affordability. However, the challenge remains: will this momentum continue as gas prices stabilize or decline?

The Impact of Price Fluctuations on Profitability

Costco’s business model is designed to thrive during periods of high gas prices. When fuel costs soar, customers are drawn to its lower rates, boosting sales. At the same time, the company’s other products, such as groceries, are sold at a margin that is often lower than traditional retailers. This creates a balancing act: high gas sales help offset losses in other categories, while low gas prices can strain overall profitability. For instance, Costco noted that it generated $2.3 billion less in gas revenue in 2025 than the previous year due to cheaper prices. The company is optimistic that this temporary setback will not derail its growth trajectory, as it continues to prioritize member satisfaction.

The broader implications of Costco’s pricing strategy are significant. By keeping gas prices low, the company not only attracts price-sensitive consumers but also reinforces its brand as a value-oriented retailer. However, the model’s effectiveness depends on maintaining consistent demand. Analysts are cautious, suggesting that the gains in membership and sales could be reversed if gas prices drop again. Investors, too, have been skeptical, with the stock declining nearly 4% on Friday after the earnings report. Despite this, Costco remains confident in its ability to sustain the trend, viewing the current demand as a sign of enduring consumer trust in its offerings.

Costco’s gas stations are a testament to the company’s ability to adapt and innovate. While the initial focus is on fuel, the stations serve as a gateway to its wider product range. This dual-purpose model is a key differentiator, allowing Costco to create a seamless shopping experience. Customers who start their day with a cheap tank of gas are more likely to continue their purchases in the store, where they encounter a variety of items—from groceries to electronics. The result is a cycle that benefits both the company and its members: low gas prices drive traffic, and in-store shopping increases overall spending.

Looking ahead, Costco’s strategy will depend on how it navigates the ebb and flow of gas prices. The company’s leadership is keenly aware of this challenge, as Vachris acknowledged during the call. “When gas prices are high, we sell more,” he explained, “but our margins are smaller.” This paradox underscores the delicate balance Costco maintains. While it thrives in high-price environments, it must also ensure that its members don’t become discouraged when prices drop. The question is whether Costco can sustain the momentum it has built so far. If gas prices fall, will the loyal base it has cultivated continue to prioritize its stations over competitors?

Ultimately, Costco’s success in selling cheap gas is a reflection of its broader business philosophy. The company has consistently demonstrated an ability to offer value without compromising quality. This is evident in its rotisserie chicken offerings, which have become a cultural phenomenon. By combining affordable fuel with low-cost, high-quality products, Costco has created a unique value proposition that resonates with its members. As the company continues to refine this strategy, it will be interesting to see how it adapts to changing market conditions. For now, the evidence suggests that customers are willing to embrace the trade-off: long lines for low prices, and a wider range of products for the same cost.

In a world where gas prices are a constant concern, Costco’s ability to provide affordable fuel has solidified its position as a key player in the retail landscape. The company’s financial performance and customer behavior indicate that its strategy is working, even if it’s not without its challenges. As Vachris noted, the current trends are a “great way to build loyalty,” and with its membership model and product diversification, Costco is well-positioned to maintain this momentum. Whether the stock’s recent dip signals a temporary setback or a long-term shift, the company’s approach to gas pricing remains a standout example of how strategic thinking can drive business growth.
