Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $56,309 today, so the real (inflation-adjusted) return is +357.1%.

Lump sum instead — $36,700 all at once in Feb 1996: $1,574,800 (+4191.0%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (May 2026): $397.09 on $400 invested (-0.7%).

⚠ 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.
