What this return means
Costco (COST) turned $1,000 into $1,912 since 2023. The total return is +91.2% over 3.6 years, as of 2026-06-01.
In compound terms that is roughly 19.8% a year, well above what a broad index has historically returned. The same $1,000 in an S&P 500 index fund would be about $1,916 over the identical span, so the index came out ahead by roughly $4. The index compounded at about 19.9% a year, a reminder that a single stock can lag a basket of them.
Getting here meant sitting through real volatility. The best single year was 2025 at +41.8%, and the worst was 2024 at +40.1%. These figures use split-adjusted closing prices and exclude dividends, taxes, trading fees, and inflation, so a real after-tax result would differ.

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 2023 through June 2026 means 42 buys and $4,200 contributed over about 3.5 years.
$100/month, dollar-cost averaged
$5,311
+26.5% on $4,200 in
Same $4,200, all in at the start
$8,031
+91.2% on $4,200 in
Going all in at the start beat spreading the buys out by $2,720. 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 $739.75 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.
