If You Had Invested $1K in Costco 20 Years Ago, Here's What You Would Have Today
If you had the foresight to invest in Costco (COST) stock 20 years ago, you could be quite wealthy today. Over the last two decades, $1,000 invested in Costco would have grown to $31,240 today, assuming dividends were reinvested. That’s a 20-year total return of about 3,024%.
Costco seems like an obvious winner today, but 20 years ago, that wasn’t the case. The lesson for investors is simple: Even “boring” businesses can be long-term stock winners, as long as they have loyal customers, disciplined management and consistent revenue gains.

The Math Behind Costco’s 20-Year Return
According to FinanceCharts' total return data, Costco’s 20-year total return was about 3,024% as of May 29.
That means each $1,000 invested would have run up to $31,240. That figure assumes dividends were reinvested along the way.
Why Costco Has Been Such a Strong Long-Term Stock
Costco’s business is a case study in customer satisfaction and profit management. By selling products at a small markup, it keeps customers happy with its prices. As a result, the loyalty to the company is staggering.
Most of Costco’s profits actually come from its recurring membership revenue. This type of predictable, consistent revenue helps give investors confidence in the ongoing earnings power of the company.
The company’s strategy is clearly working. In the first quarter of fiscal 2026, Costco reported quarterly sales of $65.98 billion – that’s quarterly, not annually.

Dividends Helped, Even If Costco Is Not a Dividend Stock
Costco doesn’t pay much of a dividend, although management did just raise it to $5.88 annually. With a stock price of $956.32 as of May 29, however, that puts its forward yield at just 0.61%.
While this cash payout isn’t significant, it still makes a difference when reinvested and compounded over time.
The Catch: Costco Today Is Not Costco 20 Years Ago
Although Costco’s returns have been impressive, looking at past performance can be dangerous. It’s only human nature to see a stock chart that has been climbing for 20-plus years and assume that it will continue forever. But as the frequently cited Wall Street disclaimer says, “Past performance is not a guarantee of future results.”
Costco still has a great business strategy and a doggedly loyal fan base. But as an investor, you can no longer buy shares at 2006 prices. And in 2026, expectations for the stock are very high.
Here’s a great example of the risk. Costco recently reported earnings that Barron’s called “solid in most regards.” Yet the very next day, the stock traded down by about 4%. Per the same Barron’s article, “It was not the blowout results some investors may have come to expect from the warehouse club retailer.”
The moral of the story is that even with a great business posting solid earnings, investors want more from Costco simply because of its prior success.
What Investors Can Learn From Costco
Investors don’t have to trade in and out of stocks or follow the latest trend to become successful over the long run. Costco’s 20-year run shows that a “boring” retail company with a strong business can still provide handsome returns.
But that doesn’t mean buying a “good” stock at a high price guarantees future returns. Even after a solid May 28 earnings report, for example, Costco stock traded down the next day. And even Costco is not immune from having some bad years, like in 2008, when it fell about 24%, or in 2022, when it dropped another 19%. But even with those big down years, the stock rewarded patient investors.
