Latest / Business Strategy Talks with Fexingo: Competitive Advantage, Market Positioning, and Growth Planning / How Costco Built Its Moat on Membership Fees
Transcript
- Lucas: We need to talk about the single most counterintuitive profit center in modern retail: the membership fee. Most people walk into Costco thinking they are there for the deals, but the company knows they are actually there to renew their cards. It sounds like a small detail, but it completely changes the math of the entire business. Luna: Right, because if you treat them like customers who just want cheap goods, you miss the whole point. The fee isn't just revenue; it's a filter. Lucas: Exactly. And here is the concrete number that anchors this entire strategy: Costco makes more money from membership fees than it does from selling products. In recent fiscal years, operating income from memberships has hovered around four billion dollars, while net income from merchandise sales is significantly lower. That means the core retail operation is essentially breaking even or making tiny margins, and the membership side is pure profit. Luna: So they are basically subsidizing the low prices to keep you coming back, which keeps the fee revenue flowing? Lucas: Precisely. They cap the annual fee at fifty-five dollars, which is aggressively low compared to competitors like Sam's Club or BJ's. But that low price creates a psychological debt. You feel obligated to shop there to justify the cost. It turns shopping into an economic imperative rather than a leisure activity. Luna: That is fascinating because it flips the traditional retail script. Usually, you drive volume to make margin, not the other way around. Lucas: Let me put a quick aside here for those listening. If these conversations have moved your work forward in some small way, a couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo. It really does help us keep producing these deep dives without ads cluttering the feed. Luna: Thanks for the support, listeners. Back to the numbers, because this subsidy model allows Costco to do something very specific with their inventory. Lucas: They limit selection. A standard supermarket might carry five hundred varieties of toothpaste. Costco carries maybe three. Why? Because by limiting SKUs, they can order massive quantities of each item, forcing suppliers to give them better prices. Then they pass those savings to you, which reinforces the membership value. Luna: It’s a tight loop. Low SKU count leads to bulk buying power, which leads to low prices, which drives membership renewals, which funds further price cuts. Lucas: And the renewal rate is the key metric. It sits around ninety percent globally, and in the United States, it is even higher, closer to ninety-two percent. For a subscription service, that is elite. For a grocery store, it is almost unheard of. Luna: But does that hold up when inflation hits? When people are cutting back, aren't they more likely to drop the fee? Lucas: Actually, it works in reverse during high inflation. When prices rise elsewhere, the fixed-value proposition of Costco becomes more attractive. People who already have memberships spend more to maximize their return on that fifty-five dollar investment. New sign-ups often accelerate because everyone is looking for a hedge against rising costs. Luna: So the moat gets deeper when the economy gets worse? That seems almost unfair to competitors. Lucas: It is unfair, but it is also hard to copy. Amazon Prime is trying to do something similar, but their model is built on convenience and content, not necessarily the thrill of the hunt for physical goods. Costco sells an experience. The treasure hunt element is critical. Luna: The treasure hunt. You mean finding random luxury items or seasonal goods that disappear quickly? Lucas: Yes. Maybe it is designer handbags, or high-end electronics, or just a really good deal on winter coats. These items are scarce and unpredictable. They create urgency. You see something you didn't plan to buy, and you buy it because it might be gone tomorrow. That impulse behavior drives average ticket size up. Luna: Impulse buying is usually seen as a negative thing in retail ethics, but here it is the engine of growth. Lucas: It is engineered impulse. The layout forces you past these items. The staff rotates stock frequently so that regulars never know exactly what will be there. It gamifies the shopping trip. You are not just buying groceries; you are playing a game where the prize is a perceived bargain. Luna: I remember reading that the rotisserie chicken and soda combo is priced at twenty-four dollars for decades. It’s a classic loss leader. Lucas: That is the anchor. They lose money on that specific combo intentionally. Why? Because once you are in the store for that deal, you are likely to buy other things. And since the membership fee covers their operational losses, they can afford to take that hit on a few items to drive foot traffic. Luna: So the loss leader isn't just about selling food; it's about proving the membership is worth it every single time you walk through the door. Lucas: Exactly. It validates the fee immediately. If you go in, get the chicken, and leave, you have still gotten a good deal. But nobody leaves after just the chicken. The store design and the scarcity tactics ensure you spend much more. Luna: What about their private label, Kirkland Signature? How does that fit into this moat? Lucas: Kirkland is the trust builder. It is often made by the same manufacturers as name brands but costs less. By controlling the brand, Costco ensures quality control and higher margins on those specific items. It also reduces reliance on external brands, giving them more leverage in negotiations. Luna: It’s a vertical integration play, but through branding rather than manufacturing ownership. Lucas: Correct. They don't own the factories, but they own the relationship with the consumer regarding quality. If Kirkland fails, the whole membership promise fails. So they are incredibly rigorous about testing. Luna: This feels like a very disciplined approach. Most companies try to do everything at once. Lucas: They refuse to diversify away from this model. They don't open small urban stores with different formats. They stick to the warehouse concept. They don't compete on delivery speed like Amazon. They compete on value and curation. That discipline is rare. Luna: Do you think this model is sustainable long-term? Or does it eventually plateau? Lucas: There are headwinds. E-commerce is eating into discretionary spending. Younger generations have different shopping habits. But the membership lock-in is powerful. Once you have a card, switching costs are psychological, not just financial. Luna: Psychological switching costs. That’s a strong term. It implies that even if another place is cheaper, you won't go because you already paid the fee. Lucas: Yes. It’s sunk cost fallacy weaponized for business. You feel stupid for wasting the membership fee if you don't shop there. So you go, even if the prices aren't the absolute lowest everywhere else. Luna: It’s a clever exploitation of human bias. I guess that’s why they raise prices slowly. They know you are locked in. Lucas: They raise prices, but only enough to maintain the margin structure. They don't push it too far because if renewals drop, the whole house of cards collapses. The balance is delicate. Luna: So it’s not just about being cheap; it’s about being predictably valuable. Lucas: Predictably valuable. That’s the key. In an uncertain market, knowing exactly what you will get for your fifty-five dollars is a form of insurance. Luna: I wonder if other industries can learn from this. Like, can a software company build a moat like this? Lucas: Maybe. Subscription software already uses the fee model. But Costco adds the physical experience and the tangible goods. It’s harder to replicate that hybrid model in purely digital spaces. Luna: True. The tactile nature of the treasure hunt is unique to physical retail. Lucas: Which is ironic. Physical retail is struggling, but Costco is thriving because it figured out how to make the physical part the advantage. Luna: It turns the inconvenience of driving to a warehouse into part of the commitment. Lucas: Exactly. If it were easy, you wouldn't value it as much. The effort required reinforces the membership identity. Luna: So, next time you renew your card, ask yourself if you are doing it for the chicken or for the feeling of being a smart shopper. Lucas: Probably both. And that duality is exactly what makes Costco’s moat so wide and so defensible. Luna: It’s a masterclass in aligning incentives between the seller and the buyer. Lucas: Agreed. It’s not just a store; it’s a club with a very specific set of rules that everyone wants to follow. Luna: I’m curious if we will see any new players trying to crack this code, or if the first-mover advantage is just too strong here. Lucas: First-mover advantage is huge, but culture is even bigger. Costco’s internal culture mirrors its external strategy. Everyone is focused on efficiency and value. Copying the model is easy; copying the culture is nearly impossible. Luna: Culture as a moat. That’s a lesson for any business leader listening today. Lucas: Absolutely. Build a system where everyone understands the goal, and the results tend to follow. Luna: We’ll have to see if any challenger emerges with a similar cultural alignment in the next decade. Lucas: It would be a fascinating case study if they did. Until then, Costco remains the gold standard for membership-based retail. Luna: For now, yes. But markets shift, and consumer patience is always finite. Lucas: True. But as long as they keep that chicken at twenty-four dollars, I doubt anyone is leaving anytime soon. Luna: A tempting offer indeed. Let’s see what happens when that price finally moves. Lucas: If it does, watch the renewal rates. That will be the real signal that the moat is cracking. Luna: Good point. Numbers don't lie, even if marketing does. Lucas: Always. Thanks for tuning in to this deep dive on competitive advantage. Luna: See you next time with another look at how businesses really win.
