Fee Income as a Flywheel: The Model That Lets Costco Win on Price Every Time
Costco’s (COST) competitive edge is structural rather than cyclical. By running intentionally thin gross margins of around 11%, the company uses high-margin membership-fee income to subsidize everything on the warehouse floor, allowing it to price more aggressively than Walmart, Target, or Publix without sacrificing profitability.
Members feel they are getting more for their money because they genuinely are, and that perception is what drives the renewal rates and membership growth that prop up the entire model.
Q3 fiscal 2026, reported May 28, showed how durable that dynamic is, as net sales reached $69.2 billion, up 11.6% year over year, with diluted EPS of $4.93, up 15.2%. Membership income grew 10.7%, with 82.9 million paid memberships on the books, a slow-but-steady 4.1% increase, and a worldwide renewal rate of 89.7%. The US and Canada are, unsurprisingly, among Costco’s most loyal customers with a renewal rate of 92.2%.
Gross margins dipped from 12.88% in fiscal 2021 to 12.15% in fiscal 2022 as commodity inflation hit, then recovered steadily to 12.84% by fiscal 2025. That recovery happened while Costco was simultaneously cutting prices on Kirkland Signature products.
Margin stability at this level, amid one of the most inflationary retail environments in decades, is a direct reflection of the fee-income cushion that competitors simply do not have.

Membership Growth and the Geography of a Global Compounding Machine
When it comes to where Costco is seeing its income, US operating income has grown from $4.3 billion in fiscal 2021 to $6.9 billion in fiscal 2025. Canada has climbed from $1.2 billion to $1.8 billion over the same period, and ‘Other International’ has expanded from $1.3 billion to $1.7 billion. Costco is targeting 940 total warehouses by the end of fiscal 2026, up from 914 at the end of fiscal 2025.
A major revenue pipeline for the company, Executive memberships, which carry a higher annual fee and generate a 2% purchase reward, now represent 41.2 million of the 82.9 million paid memberships and account for 75% of all sales.
Every upgrade increases per-member fee revenue and tends to drive higher spending, compounding the model over time without requiring price increases for anyone. Since only half of all members have converted, this leaves the door open for continued revenue bumps from the remaining ~41 million non-Executive members.
A major note for investors, especially in light of ongoing gas price increases ahead of a potentially busy summer travel period, is that the final five weeks of Q3 2026 saw Costco’s best-ever gas station volume, as price-sensitive consumers sought cheaper fuel. In addition, digitally-enabled comparable sales grew 21.5%, with e-commerce site and app traffic up 37%, so things are looking good for Costco right now, and investors need to take note.
Personalized recommendation carousels are driving conversion rates 3x higher than standard benchmarks, and management is actively leveraging large language models to improve product page relevance.

What the TIKR Valuation Model Says About COST at $972
When it comes to the future of Costco stock, TIKR’s mid-case valuation model targets around $1,930 for COST, implying a total return of around 98% from the current price, or roughly 9% annualized over the next 4.2 years. The model assumes around 7% annual revenue growth and net income margins holding near 3.2%, with EPS growing at around 9% per year on a compounded basis.
The honest friction is the starting multiple, which is right around 51x trailing earnings and 46x forward earnings. The model assumes modest P/E compression of 1%-2% annually, implying the return comes almost entirely from earnings growth rather than re-rating.
The low case lands at around $1,505, still representing around 55% upside. The high case reaches around $2,400. Guggenheim and DA Davidson are among firms maintaining hold ratings on valuation grounds, while the broader Street consensus is a buy, with a mean target of around $1,110.
Is COST Worth Buying at Today’s Levels?
Up 12% year-to-date as of June 5, 2026, Costco has already rewarded patient investors this year. The Q3 2026 results were strong across almost every metric, and the gas station traffic record in the final five weeks of the quarter is a reminder of exactly when and why the value proposition resonates most.
The valuation is the honest friction point, as paying 51x earnings for a retailer with 3% net margins requires real conviction in the membership flywheel. Over the past decade, that conviction has been well-rewarded, with COST generating a total return of over 660%, more than double the S&P 500.
For long-term investors who believe the international expansion runway and digital acceleration justify the premium, the current price is defensible. For investors focused on near-term value, the setup asks for patience and a willingness to own a business that rarely, if ever, goes on sale.
