Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $47,037 today, so the real (inflation-adjusted) return is +924.1%.

Lump sum instead — $32,200 all at once in Nov 1999: $2,508,366 (+7690.0%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Feb 2026): $738.96 on $700 invested (+5.6%).

⚠ Price returns only — dividends are not included. This understates the true return of dividend-paying shares, and any comparison against crypto (which pays no dividends) is biased against equities by roughly the dividend yield, compounded.
