Is Costco Worth the Premium? A Framework

The question this article will and will not answer

The question of whether Costco is worth the premium hides two very different judgments, and the mistake most buyers make is letting one answer the other. The first is about the business: is this genuinely a wonderful company? The second is about the price: even so, is 52 times earnings a sensible thing to pay? We will not tell you what to do. We will separate the two questions, work each on its own terms, and then hand the decision back to you. You can follow the live figures from the Costco report on Tenet.

Keeping the two apart is the whole discipline. A great business bought at any price is not automatically a great investment, and the way the two part company is exactly the subject of when a great business is too expensive. Costco is a clean test case for that idea.

What Costco is today: the quality question

On business quality, Costco clears the bar with room to spare, and it does so because of one unusual feature: it barely tries to make money selling you things. In fiscal 2025 Costco reported revenue of about $275 billion and net income of roughly $8.1 billion, according to its 10-K, on a gross margin near 12.8 percent of total revenue. A typical retailer would find that unsurvivable. For Costco it is the strategy.

The profit comes from the membership card. Membership fee income was roughly $5.3 billion in fiscal 2025, set against operating income of about $10.4 billion, so fees supply about half of operating profit while the warehouses run close to break-even on merchandise. That structure creates a loop rivals struggle to break: enormous buying volume, deliberately thin markups, low prices that bring members back, and renewals that feel worth paying again. The evidence the loop works is the renewal rate, which Costco has reported around 90 percent in the United States and Canada for years. When nine of ten members choose to pay again, you are looking at a moat expressed as a number rather than a slogan.

The balance sheet reinforces the quality verdict. Costco has run a net cash position, holding more cash and short-term investments than total debt, which gives it freedom to expand and to ride out downturns without leaning on lenders. Return on invested capital near 19 percent, unusual for a grocer, is the fingerprint of a real advantage rather than a lucky stretch. On the business, in short, there is little to argue about.

The record backs that up. Over the five fiscal years through 2025, Costco compounded revenue and earnings without a single down year, through a pandemic and an inflation spike alike.

Figures are from Costco's filings and Tenet data as of July 2026, showing selected years. Revenue compounded near 10 percent a year and earnings per share near 15 percent over the span. Past results do not predict future returns, but consistency this steady is exactly what a durable business looks like, and it is the reason the market is willing to pay up. What the record cannot tell you is whether the next decade repeats it at a price near 52 times earnings.

What today's price already assumes: the price question

Now the second, separate question, and it is where Costco asks the most. In July 2026 the shares traded around $950, a market value near $421 billion, against fiscal 2025 diluted earnings of $18.21. That is a trailing price-to-earnings multiple of about 52.

Set that against Costco's own history, not against other companies. For much of the past decade the stock carried a multiple in the high 30s. A move from the high 30s to the low 50s is not a rounding error. It means buyers today pay meaningfully more for each dollar of Costco's earnings than buyers did a few years ago, for a business growing at a broadly similar pace. The re-rating, not the growth, is what changed.

The useful way to frame the price is to read it as a forecast, an approach sometimes called expectations investing: instead of asking "what is Costco worth," ask "what does this price already expect Costco to do." A multiple of 52 carries an earnings yield near 1.9 percent, meaning a year of current earnings buys under two cents on the dollar invested. For that to become a good return, earnings have to compound for a long time, and the price already assumes they will. There is little disappointment priced in. That way of thinking is developed in understanding market expectations, and the deeper question of what the business is truly worth is the subject of intrinsic value. Working that worth out from the fees and the merchandise margin is the exercise walked through in step-by-step company valuation.

A quick sense check makes the premium concrete. Costco grew earnings per share from $9.02 in fiscal 2020 to $18.21 in fiscal 2025, a compound rate near 15 percent. If it keeps compounding near that pace and the market keeps awarding a premium multiple, today's price can work out. If growth settles into the low teens and the multiple drifts back toward its historical high 30s, a buyer could see earnings grow for years while the shrinking multiple eats much of the return. Small changes in those two assumptions, growth and exit multiple, swing the outcome widely. That sensitivity is the entire premium question.

Holding the two judgments apart

The reason to separate quality from price is that they pull in opposite directions here, and blending them produces muddled thinking. The table lays the split out plainly.

Figures reflect fiscal 2025 results and the July 2026 price. The point of the table is not to net the two into a score. It is to keep you from letting the strong left column quietly answer the hard right one. "This is a great company" is true. It is also not, by itself, an answer to "is this a sensible price." Investors who conflate the two end up paying any multiple for quality, which is how wonderful businesses become mediocre holdings, a pattern traced across decades in Costco as a long-term compounder.

What would have to be true for you

Because we are not handing you a verdict, the decision comes down to a short list of questions you have to answer honestly. This is the "what would have to be true" test, the same reasoning laid out in building an investment thesis: for Costco at today's price to reward you, several things must hold.

1. Can growth stay near its recent pace? Much of the case rests on Costco compounding earnings in the low-to-mid teens for years, through new warehouses, membership growth and gentle fee increases. If growth slows, the multiple looks harder to justify.
2. Will the multiple hold? At 52 times earnings, a large part of your return depends on the market continuing to pay a premium. A drift back toward the historical norm would be a headwind even if the business performs.
3. What return do you actually need? At an earnings yield near 1.9 percent, the price offers little margin of safety. If you require a real discount to a defensible value, this may not be it; if you are buying durability to hold for decades, you may weigh that differently.
4. What is your time horizon? A premium multiple is far easier to hold for ten years than for one, because time lets earnings grow into the price. Your holding period changes the calculation, a theme in when to buy a stock.

There is no answer key. Two rational investors can look at the same split, agree entirely on the quality, and still disagree on whether the premium is worth paying, because they bring different growth views, return targets and horizons.

So, is Costco worth the premium?

That is yours to decide, and now you have the two judgments cleanly separated: a business that clears the quality bar with ease, and a price that already assumes years of steady growth and leaves thin room for error.
