In September 2024, Costco raised annual membership fees in the United States and Canada. This move supplied about 40 percent of the year’s growth in membership-fee income. This is a cleaner stress test than most pricing decisions. A warehouse chain can hide a weak product mix for a while. It cannot hide a fee change from the people who pay it every year before they walk through the door.
Costco’s annual report for 2025 still leans on the same engine it always has: new members, renewals, and very large numbers of people deciding the fee is still worth it. The hike is more than a line item. It is a small public exam for the business model itself.
What Costco actually sells
Costco does not just sell groceries, tires, electronics, and rotisserie chickens. It sells access to a system that makes those things feel cheaper, simpler, and slightly ridiculous in quantity. The membership fee sits on top of that system like a toll. For a business built this way, the fee is part of the operating design.
The timing of fee increases is important. Costco does not reach for the price lever every quarter. Its previous membership-fee changes were in 2017 and 2006. This means the company tends to let the value story age before it asks customers to pay more for it. This is a very different gesture from a business that nudges prices because it can. Costco asks for more only when it believes the customer already knows the answer.
The model only works if shoppers believe the annual fee is repaid in lower prices, bulk savings, private-label value, cheap fuel, and the sense that the warehouse will still be there next week with the same deal on paper towels. Strip that away and the membership becomes a subscription to errands. Nobody wants that.
What changed in 2024
The September 2024 increase forced every member to do a private calculation. Not a spreadsheet one, just the one people do in their head at the till. Am I getting enough back to justify this? Costco’s answer was to make the price change small enough that most members would not bother doing the work of leaving, but large enough to matter in the accounts.
The result was neat. In the 2025 annual report, Costco said the increase accounted for roughly 40 percent of the year’s growth in membership-fee income. This tells you two things at once. First, the price hike had real financial weight. Second, the company did not need a flood of new members to make it pay off. The existing base, plus renewal behavior, did most of the work.
This separates pricing power from simple administrative success. If people renew because they barely noticed the change, the company has inertia on its side. If they renew because they looked at the new fee and still felt stupid leaving, that is something stronger. Costco wants the second outcome. The first one can disappear the moment a rival offers enough convenience to make the effort worthwhile.
Where the money goes
Membership models look tidy from the outside because the customer pays up front and the money arrives on schedule. Inside, the arithmetic is more annoying. A company like Costco can charge low markups on merchandise because the fee covers a chunk of the economics. This gives it room to keep prices sharp on the floor, which in turn makes the membership easier to defend. The loop is the point.
A fee increase tests whether that loop still turns. If renewal rates stay high, the business has a real moat. If cancellations spike, the company learns that some customers were never loyal, only lazy. They stayed because the fee was low enough to ignore. That is a very different asset.
Watching revenue alone is too crude. A price change can lift income while quietly thinning the customer base you actually care about. You need to know who left, why they left, and what sort of customer left first. A family that shops every week is not the same as someone who shows up twice a year for bulk detergent and Christmas cookies. Treating them as one blob is how companies persuade themselves the hike went well when it simply hit the least visible part of the base.
What was knowable at the time
Costco did not need a crystal ball. It had several practical clues. Its renewal rates have long been high in the United States and Canada, and globally they are still strong enough to make the business look stubborn in the best sense of the word. The company also knew its value proposition was unusually legible. Shoppers know why they go there. That clarity gives management more room to raise the membership fee without detonating the relationship.
The harder lesson is for everyone else. Before raising prices, segment customers by usage and profitability. Find the people who come often, spend enough to matter, and would feel real pain if a core benefit vanished. Then identify the benefits they would actually miss, not the ones they politely say they like in a survey. You learn more from what people would complain about losing than from what they say they admire.
Cancellation reasons matter. If members leave because the fee rose and nothing else changed, the model was already thin. If they leave because they were barely using the service, the price hike has done useful work by separating committed customers from accidental ones. A business that cannot tell the difference is not pricing, it is guessing.
What the test really proves
A successful increase says customers still understand the exchange. They know what they are paying for, they can feel the benefit, and the company has enough pricing power to ask for more without breaking trust. A failed increase says the opposite. It means the business was being carried by habit, not allegiance, and habit is a cheap employee.
Costco’s 2024 move offers a useful reading. The fee rise was not a clerical adjustment. It was a live test of whether the membership was a real asset or a tolerated expense. Costco appears to have passed. The open question for anyone watching from the outside is sharper: how many other companies think they have loyalty when all they really have is people who have not yet bothered to leave?
