Microsoft exemplifies the 'quality stock' pattern — a company that proved it could reinvent itself. The 'lost decade' of 2000–2013 teaches that even excellent companies can stagnate for years. The key was patience: those who held through the difficult period enjoyed remarkable growth in the decade that followed under Satya Nadella's cloud-first transformation.
MSFT offers a rare combination of growth and stability: with a strong balance sheet, rising dividends, and massive cash flow, it's considered one of the safer 'Blue Chip' tech investments. The stock trades around $402 as of March 2026.
The calculator shows split-and-dividend-adjusted prices — a 1990 share price is displayed as what it would equal today after adjustments. This enables true return comparisons across decades. Past performance doesn't guarantee future results.
Enter your investment amount, select buy year (from 1986) and sell year (or 'Today'), and click Calculate. Prices are split-adjusted to reflect true historical returns.
