Costco Membership Model: 7 Lessons for DTC & Shopify Brands

The Costco membership model is a retail strategy where the company sells merchandise at razor-thin margins and earns most of its profit from recurring annual membership fees instead of product markups. For DTC and Shopify brands, the takeaway is direct: a paid membership can turn one-time buyers into renewing subscribers whose fees drop almost entirely to the bottom line. Costco has proven the math at massive scale, and nearly all of it runs on public financial data any founder can study.

Here is the whole idea in one number. In early fiscal 2026, membership fees accounted for roughly 53% of Costco’s operating income even though the merchandise itself carries gross margins near 11%. The stuff on the shelves barely makes money. The card in your wallet is the product.

What is the Costco membership model, exactly?

The Costco membership model treats products as a near break-even loss leader and the annual membership as the actual profit center. Customers pay a yearly fee for the right to shop, and in exchange Costco commits to selling a curated, limited assortment at some of the lowest markups in retail. The fee, not the margin, is what compounds.

This inverts how most brands think. A typical retailer chases gross margin on every unit; Costco deliberately caps its markups and makes the difference back on fees that renew year after year. The result is a recurring-revenue business wearing a warehouse costume—closer to a subscription company than a traditional store.

Why are Costco’s membership fees “almost all profit”?

Membership fees are almost pure profit because they carry virtually no cost of goods sold. When a member pays $65 or $130, there is no inventory, freight, or shrink attached to that dollar the way there is on a rotisserie chicken. It flows down to operating income at a rate no merchandise sale can match.

The scale is real. Costco’s membership fee income reached $1.24 billion in a single quarter of fiscal 2025, up 10.4% year over year, driven by both new sign-ups and the September 2024 fee increase. Because that revenue is so clean, small fee changes move profit disproportionately.

This is the single most transferable insight for a DTC founder. If you can attach a recurring, low-cost fee to an experience customers already value, you build a profit layer that is insulated from the margin pressure on your core catalog.

How loyal are Costco members?

Costco members are extraordinarily loyal, with a renewal rate around 92.3% in the U.S. and Canada and 89.8% worldwide as of fiscal 2025. Domestic renewals have held above 90% for years. Critically, that loyalty barely flinched when Costco raised fees in September 2024 for the first time in seven years.

Two forces drive this stickiness. First, the fee creates a sunk-cost commitment: once you have paid, you shop more to justify it, which raises basket size and reinforces the habit. Second, the Executive tier pays members a cash reward on their spending, so renewing literally pays for itself for heavy buyers. Loyalty is engineered, not hoped for.

The membership economics, tier by tier

The table below breaks down Costco’s two consumer tiers using its September 2024 pricing and fiscal 2025 mix. The pattern to notice: the premium tier is a minority of members but the overwhelming majority of sales.

Metric	Gold Star	Executive
Annual fee (2024 increase)	$65 (was $60)	$130 (was $120)
Annual reward cap	None	$1,250 (was $1,000)
Share of members	~52.7%	47.3%
Share of worldwide sales	~27%	~73%
Behavior	Habitual value shopper	Heaviest, most loyal spender

The lesson embedded here is tiering. Costco does not push everyone to spend more; it gives its best customers a paid reason to consolidate their spending, then lets the reward cash back deepen the relationship. A $1,250 reward cap is not generosity—it is a mechanism that makes leaving expensive.

Three lessons DTC brands can steal from the Costco membership model

DTC and Shopify brands can adapt the Costco membership model without a warehouse or a food court. The transferable mechanics are paid membership, curated access, and loss-leader math—and all three work at small scale.

First, sell a paid membership, not just perks. A free loyalty program is a discount; a paid tier is a commitment that filters for your best customers and generates high-margin fee revenue up front. Even a modest annual fee that unlocks member pricing changes the psychology of every future purchase.

Second, curate ruthlessly and price the hero items near cost. Costco stocks a fraction of the SKUs of a normal grocer and treats staples as traffic drivers. A Shopify brand can do the same: run a few signature products at break-even to justify the membership, then earn margin on the long tail and the fee itself. This is the same demand-concentration logic behind group buying models like Pinduoduo, and it powers platforms such as Farabiulder, where pooled demand unlocks pricing individuals cannot get alone.

Third, make renewal pay for itself. The Executive reward is Costco’s retention engine. Your version might be store credit, cash back, or a spending threshold that clearly returns more than the fee costs—so canceling feels like leaving money behind.

How to model the payback before you launch

Before launching a paid tier, model whether the fee plus incremental spend exceeds your acquisition cost per member. The Costco model only works because a member’s lifetime value dwarfs what it cost to sign them up, and renewals extend that value for years at almost no added cost.

Run the numbers on your own funnel: estimate fee revenue, expected renewal rate, and the lift in purchase frequency a membership creates, then compare that to your blended customer acquisition cost. If members buy more often and stay longer, the fee effectively subsidizes acquisition. That is the quiet engine behind Costco’s valuation—and the reason customer lifetime value matters more than any single conversion. You do not need Costco’s scale to copy its logic; you need a fee your best customers are glad to renew.
