What this return means
A $1,000 position in Microsoft (MSFT) opened in 2005 is worth $20,697 today. That works out to +1969.7%, about 21x the original stake, as of 2026-06-01.
In compound terms that is roughly 15.1% a year, well above what a broad index has historically returned. A plain S&P 500 fund would have turned that $1,000 into about $9,342 instead, leaving Microsoft ahead by around $11,354. The index compounded at about 10.9% a year over that period.
The path was not smooth. The best single year was 2010 at +68.7%, and the worst was 2009 at -46.6%. At its lowest point the position was down about 47% 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 Microsoft at the close of every month from January 2005 through June 2026 means 258 buys and $25,800 contributed over about 21.5 years.
$100/month, dollar-cost averaged
$260,958
+911.5% on $25,800 in
Same $25,800, all in at the start
$534,069
+1,970.0% on $25,800 in
Going all in at the start beat spreading the buys out by $273,111. 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 $36.88 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 MSFT split-adjusted monthly closes through June 2026. Past performance does not guarantee future results.
