What this return means
A $1,000 position in Costco (COST) opened in 2000 is worth $28,693 today. That works out to +2769.3%, about 29x the original stake, as of 2026-06-01.
That is about 13.5% a year compounded, broadly in line with long-run stock market averages. By comparison the S&P 500 returned about $8,517 on the same stake, putting Costco ahead by close to $20,176. The index compounded at about 8.4% a year over that period.
The year-by-year record shows how bumpy the ride was. The best single year was 2022 at +44.4%, and the worst was 2003 at -37.2%. At its lowest point the position was down about 41% from an earlier high. These figures use split-adjusted closing prices and exclude dividends, taxes, trading fees, and inflation, so a real after-tax result would differ.
None of this is a recommendation. It is a record of what already happened, and past performance does not guarantee future results.
What if you invested $100 a month instead?
Most people do not drop a lump sum in on day one. They add a fixed amount every month. Putting $100 into Costco at the close of every month from January 2000 through June 2026 means 318 buys and $31,800 contributed over about 26.5 years.
$100/month, dollar-cost averaged
$513,658
+1,515.3% on $31,800 in
Same $31,800, all in at the start
$912,514
+2,769.5% on $31,800 in
Going all in at the start beat spreading the buys out by $398,855. That is the usual result when a stock trends up: each monthly buy pays a higher price than the last, so the average cost climbs. Averaging in also meant an average buy price of $57.91 per share across the whole stretch, so the monthly buyer never had to time a single low. Neither number counts dividends, taxes, or trading costs.
Illustrative fixed $100/month example, not a recommendation. Figures are computed from COST split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
