For Costco, the membership fee is not a footnote — it is the entire story. While the warehouse giant moves hundreds of billions of dollars in merchandise every year, its actual profits trace back to a much smaller, much more powerful number: the annual dues paid by the tens of millions of cardholders who line up at its warehouse doors. For the past year, those fees have been running hotter than usual, fueled by a price hike that took effect in September 2024. Now, as the calendar turns and Costco's fiscal year matures, that tailwind is nearly spent — and Wall Street is paying close attention to what comes next.
The Fee Hike That Changed Everything
Context is everything here. In September 2024, Costco implemented its first membership fee increase since 2017, raising the standard membership fee by $5 and the executive membership fee by $10. That seven-year gap is not an accident — Costco has always been deliberate, almost painfully conservative, about testing the loyalty of its member base. Costco raised its premium club membership fee to $130 annually from $120, the first price hike in seven years. For a company whose entire financial architecture rests on whether people renew their cards, charging more is never a casual decision.
Effective September 1, 2024, Costco increased its membership fees in the U.S. and Canada for Gold Star, Business, and Business affiliates to $65 per year. The Executive membership fee increased from $120 to $130, and the maximum annual 2% reward associated with the Executive Membership increased from $1,000 to $1,250. That reward cap increase was a quiet but meaningful sweetener — a way to justify the higher price tag by making the math work for heavy shoppers who spend enough to hit the old ceiling anyway.
The accounting mechanics that follow a fee hike are critical to understanding why this story is playing out now rather than immediately after September 2024. Costco collects fees up front and recognizes them over each member's one-year term. That means the 2024 increase has been phasing in gradually — and by now, it's nearly done. In practical terms, the boost has been arriving in slow motion, spread across four quarters, rather than hitting the books all at once. Costco accounts for membership fee revenue on a deferred basis, recognized ratably over the one-year membership period. Due to this deferral, the increases had an immaterial impact in the first quarter of fiscal 2025.
The Numbers Behind the Tailwind
How Big Was the Fee Hike's Impact?
Analysts estimated that the fee hike could add approximately $290 million to Costco's operating income, representing a modest 2% to 4% boost for fiscal 2025. Costco's own 10-K filing put the projection slightly higher. The company expected these fee changes to increase revenues approximately $370 million over the next two years, with $190 million benefiting fiscal 2025, primarily in the latter half of the year. Either way, those figures underscore both the power and the limit of a price hike: meaningful, but one-time in nature.
The fee income line itself is not small change. In fiscal 2025, membership fee income came to $5.3 billion — about half of the $10.4 billion the company earned in operating income. To put that in starker terms: Costco sells enormous quantities of everything from rotisserie chickens to 72-inch televisions, and none of those transactions come close to generating as much bottom-line profit as the dues check its members cut every year. The way membership fees drive Costco's bottom line means the entire company can grow earnings faster by growing membership fees than by selling more merchandise.
Growth Slowing Quarter by Quarter
The fee hike delivered its biggest punch when it was newest. In last year's fiscal fourth quarter, membership fee income rose 14% year over year. It grew nearly 14% through the first half of fiscal 2026, then slowed to 10.7% growth in the fiscal third quarter — the 12 weeks ended May 10 — when it came in at $1.37 billion. That deceleration is not a crisis, but it is a signal. The price hike has been doing heavy lifting; as it fully phases out of the year-over-year comparisons, the remaining growth rate will represent the underlying, organic strength of the membership business — no artificial inflation, no one-time boost.
CFO Gary Millerchip said on the fiscal third-quarter earnings call that a little more than a quarter of that growth came from the higher U.S. and Canada membership fees that took effect in September 2024. That figure — just over a quarter of the growth — is notably lower than what the fee hike was contributing in earlier quarters. The fade is playing out exactly as the deferred-revenue accounting would predict, and the final quarter of fiscal 2026 is likely to be the last earnings report where the 2024 hike contributes anything meaningful at all.
The Organic Machine Underneath
Strip away the fee hike and what remains is still a genuinely formidable business. The September 2024 membership fee increase in the United States and Canada contributed to less than half of the quarterly growth in fiscal 2025's fourth quarter, highlighting that most of the rise came from new sign-ups and member upgrades. Excluding the membership fee increase and foreign exchange effects, membership income grew 7% from the same period last year. Seven percent organic growth in a business this size, in this economic environment, is not a consolation prize — it reflects real expansion in the member base and a genuine migration of members toward the more expensive Executive tier.
Paid memberships climbed 6.3% to 81 million during the quarter. Executive members grew 9.3% to 38.7 million, now accounting for nearly 47.7% of total paid members and 74.2% of global sales. The Executive member story is particularly important. These are Costco's most committed customers — people who spend enough to justify paying $130 a year rather than $65, and who generate roughly three-quarters of everything the company sells globally. The faster that tier grows, the more the overall membership income line grows, even without another fee increase.
The Renewal Rate Question
Any time a company raises prices, the immediate investor reflex is to check whether customers walked. Costco's answer, so far, has been reassuring but not spotless. Management reported during its fiscal year 2026 second-quarter earnings call that U.S. and Canada members renewed their memberships at 92.1%, down just 10 basis points lower than the prior year. At the same time, management credited the 2024 price increase for one-third of Costco's membership fee growth in the quarter — 33% growth at just a 0.1% decline in renewals. The math is almost embarrassingly favorable: price up, volume barely down, income way up.
Still, analysts have noted some nuance in who is renewing and who is not. Costco experienced a minor setback, with the worldwide renewal rate easing to 89.8% from 90.2% in the preceding quarter. The renewal rate in the United States and Canada fell 40 basis points sequentially to 92.3%. Management attributed this decline to a higher proportion of online sign-ups, including promotional activity such as the large Groupon campaign. Online joiners, it turns out, behave differently from in-warehouse converts. These patrons tend to sign up online, with "modestly higher churn rates," and Costco senior management indicated this could lead to a downtick in membership renewal rates into 2026.
To address this, the company is promoting auto-renewal, enhancing targeted digital communication, and adding new member benefits such as extended warehouse hours and a $10 monthly Instacart credit for Executive members. Younger members now comprise nearly half of new sign-ups, and the focus is on improving the renewal rate among this newer group. The Instacart credit is a telling detail: Costco is trying to win over a generation of shoppers who value convenience delivery as much as warehouse bargains, without abandoning the in-store experience that built the brand.
Gross Margin Under Pressure
The membership fee conversation does not exist in a vacuum. Costco's merchandise business has its own set of pressures right now that compound the significance of any deceleration in fee income. Costco's gross margin was 11.04% of net sales in the fiscal third quarter, down from 11.25% a year earlier. Strip out the effect of gas prices and the rate was essentially flat. Management also said margins slipped slightly in fresh foods and its food and sundries business, where it invested in lower prices on everyday items like eggs and beef.
This is the central paradox of the Costco model: the company deliberately keeps merchandise margins thin to preserve its value proposition to members. If the groceries and gasoline and electronics are not cheap, the membership card loses its rationale. So management accepts modest merchandise profitability and relies on the fee line to carry the weight. Some of the swing factors are out of management's hands, starting with gas prices. Tariffs are a factor, too. A global trade environment that raises input costs puts Costco in the uncomfortable position of absorbing those costs, passing them on, or somewhere in between — none of which is costless.
The DoorDash Wild Card
One development that has generated real excitement — but will not show up in the numbers for some time — is Costco's move into delivery through DoorDash. Costco's nationwide launch on DoorDash came September 17, after the fiscal third quarter ended. Any membership boost from it belongs to fiscal 2027. The timing is notable: the partnership went live right as the 2024 fee hike is finishing its run through the financial statements. If DoorDash drives new sign-ups or reactivations among lapsed members — particularly among younger urban consumers who have never set foot in a warehouse — it could pick up some of the growth baton exactly when the fee hike is dropping it.
The strategic logic is not complicated. Costco has historically relied on the in-person experience — the free samples, the treasure-hunt merchandise displays, the $1.50 hot dog — to close new members. DoorDash access expands that funnel dramatically, reaching people who may never have made the trip to a warehouse but are willing to pay $65 or $130 a year for same-day delivery from a brand they already trust. Whether that works in practice will be one of the defining membership stories of fiscal 2027.
What Wall Street Is Watching
The Valuation Problem
None of this financial analysis happens in isolation from the stock price. The stock still isn't cheap. At about $899 as of this writing, down from a 52-week high of $1,096.50, shares sell for about 45 times earnings. A price like that rests on the profit lines, not the sales line. A 45x earnings multiple is a statement of extraordinary faith — faith that Costco's earnings will grow consistently enough over the coming decade to justify paying that premium today. Every quarterly report is therefore a referendum on that faith.
When the membership fee tailwind was blowing strong, that faith was easy to sustain. Double-digit fee income growth, expanding paid membership rolls, and a renewal rate north of 92% make for a compelling story. As the fee hike fades from the year-over-year comparison, the question becomes whether organic growth — new sign-ups, Executive upgrades, and DoorDash-driven acquisitions — can keep the fee income line growing fast enough to justify a stock price that already prices in a great deal of optimism.
The Next Hike: When, Not If
The question of when Costco raises fees again is increasingly central to any long-term investment thesis. The 2024 hike was the first in seven years, and the data it generated has been instructive. Management probably wouldn't want to kill the golden goose by raising fees too quickly or too often. Still, the data shows that Costco's brand power and customer loyalty likely would enable management to raise fees sooner than in another seven years from now.
In that scenario, there could be upside to Costco's earnings growth, which analysts currently estimate will average 10% annually over the next three to five years. If a fee increase materializes before the seven-year mark — say, in 2027 or 2028 — and membership rolls continue to expand at their current pace, the compounding effect on earnings per share could be substantial. The 2024 hike demonstrated that Costco can raise prices with minimal member defection, and that lesson will not be forgotten in Issaquah.
Analysts anticipate membership fees to increase 9.1% in fiscal 2026, following 10.3% growth registered in fiscal 2025. That modest step-down in projected growth reflects the loss of the fee hike tailwind, but it also suggests that the underlying member acquisition and upgrade engine is performing well enough to keep the line moving in the right direction without extraordinary help.
The Warehouse Empire Keeps Growing
However this earnings quarter resolves, it is worth stepping back and appreciating the scale of what Costco has built. Since first opening its doors in Seattle in 1983, Costco's empire has rapidly expanded. The number of warehouses worldwide stands at 914 locations as of August 31 — up from 890 warehouses around a year prior. Each new warehouse is a new membership acquisition engine, staffed by people who are exceptionally good at converting first-time visitors into annual card-carrying members.
At the end of fiscal year 2025, business looked good for the retailer: net sales jumped 8%, and membership fee revenue climbed 10%, due to new sign-ups and fee increases. Those are not the numbers of a company in trouble. They are the numbers of a company managing a growth narrative that has temporarily gotten a little more complicated — and that, for investors, is the distinction worth making. The 2024 fee hike is fading from the comparison base. The question is not whether Costco remains a strong business. It is whether the stock, at 45 times earnings, already knows that.
What It All Means for the Member in the Parking Lot
For the average Costco cardholder — the guy who goes on Saturday morning for the rotisserie chicken and ends up with a 65-inch television and a five-pound bag of almonds — most of this is noise. The annual fee went up a few dollars two years ago, and the experience at the warehouse has not changed in any meaningful way. The free samples are still there. The $1.50 hot dog is constitutionally protected. The Executive reward cap went up, which is quietly nice for people who spend enough to hit it.
What changes for members is more subtle: Costco needs that renewal check to keep arriving. That institutional imperative — the near-obsessive focus on renewal rates and member satisfaction — is ultimately what makes the company operate as well as it does. Costco's institutional priority, above everything else, is ensuring that members renew. That pressure keeps prices low, keeps quality high, and keeps the warehouse experience compelling enough to justify writing that annual check. The fee hike's math is nearly exhausted. The business built on top of it, however, is nowhere near done.
