What Dividend Investors Need to Know About Costco

Costco (NASDAQ: COST) just rewarded its shareholders with another huge dividend increase. The 13% hike is inline with the 12% average annualized increase over the past decade. Dividend growth investors should be very pleased.

However, Costco isn’t just another retailer. It is a club store, and that changes the equation in a very important way. If you own the stock, this is what you need to know.

Costco’s model is different

As noted, Costco is a club store. That means its customers pay an annual membership fee for the privilege of shopping at the company’s stores. This single fact changes everything, but some numbers will help show why.

Through the first half of fiscal 2026, Costco generated revenues of $136.9 billion. That’s a big number, noting that Costco is one of the world’s largest consumer staples businesses, second only to retail juggernaut Walmart (NASDAQ: WMT). However, Costco breaks down sales into two distinct categories, product sales and membership fees. Membership fees are a tiny fraction of the top line, making up just under 2% of revenues.

That seems like a number you could ignore, but it isn’t. Merchandise and SG&A costs totaled $131.8 billion in the first half of the fiscal year, resulting in gross profit of roughly $5 billion. But almost all of those costs are associated with operating the company’s stores. The membership fees largely fall directly into gross profit. That 2% of revenues figure noted above translates to nearly $2.7 billion in income, or more than half of the company’s gross profit!

Costco has to keep its customers happy

Once you see how important the membership fees are, you realize that Costco has an annuity-like income stream underpinning its retail business. That’s not the norm in the retail sector, where price competition is often a major factor. Costco is highly incentivized to do whatever it takes to get its customers to renew their memberships. And, as an investor, you need to pay attention to its success rate. The worldwide renewal rate was 89.7% in the fiscal second quarter of 2026, steady with the first quarter but down from 90.5% in the same fiscal quarter of 2025.

The year-over-year drop isn’t the end of the world, but it’s worth monitoring. That’s especially true given world events, with the geopolitical conflict in the Middle East likely to push costs higher across the board. The most obvious direct impact will be on transportation costs, as high oil prices quickly get reflected in gas prices. However, the full impact of the tensions will eventually flow through the entire value chain, from farmers paying more for fertilizer to rising packaging costs. Customers are already tightening their budgets, but those efforts could intensify further.
