Costco just reported quarterly revenue that topped Wall Street's estimates, and the stock has been one of the steadiest performers in the S&P 500 over the past decade.
But the number that matters most to shoppers—and increasingly to investors—isn't on the income statement.
It's the $1.50 hot dog and soda combo that has stayed frozen in price since 1985.
That single item tells you more about Costco's business model than any earnings call.
The company makes most of its profit from membership fees, not from the products on its shelves.
Those fees are pure margin, and they keep coming in whether members buy one rotisserie chicken or a pallet of paper towels.
In its most recent quarter, Costco's membership renewal rate held above 90% in the U.S. and Canada.
That loyalty is why the stock trades at a premium valuation—often around 45 to 50 times earnings, roughly double the typical S&P 500 company.
Investors are paying up for predictability, not explosive growth.
Walmart, Kroger, and Target have all fought to keep shoppers from defecting during the inflation surge of the past few years.
Costco's answer was to hold the line on the hot dog, the chicken, and a handful of other loss leaders, betting that the goodwill brings members back through the door again and again.
Costco has consistently posted comparable sales growth even as other retailers warned of stretched consumers.
When shoppers feel squeezed by rent, groceries, and credit card rates, a store that still sells a full meal for a buck-fifty becomes a weekly ritual, not a one-off trip.
The stock's high multiple leaves little room for a stumble.
Any slowdown in membership growth or a hit to renewal rates could send shares down sharply.
Costco also faces rising wage pressure and the same tariff uncertainty hanging over every major U.S. retailer.
Costco's former CFO once famously told the CEO that if the price ever went up, "I will kill you." That line has become a meme, but it also captures something real: the company treats that $1.50 as a marketing budget, not a profit center.
For everyday investors, Costco's story is a reminder that the best consumer businesses often make money in places shoppers never think about.
You walk in for cheap gas and a $5 chicken.
You walk out having paid an annual fee that flows almost straight to the bottom line.
If you already own the stock, the ride has been smooth, but the valuation means you're paying for that smoothness in advance.
If you don't own it, watching your own Costco receipt might tell you more about the company's health than any analyst report.
The takeaway: Costco's stock isn't cheap, and that's the point.
It's priced like a subscription business that happens to sell groceries—and as long as Americans keep renewing their memberships to chase a $1.50 lunch, the model keeps humming.
Final Thoughts
Just don't expect the hot dog to move anytime soon.
