Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $80,907 today, so the real (inflation-adjusted) return is +18489.6%.

Lump sum instead — $46,700 all at once in Oct 1987: $57,455,945 (+122932.0%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Jun 2026): $325.44 on $300 invested (+8.5%).

⚠ 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.
