Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $93,457 today, so the real (inflation-adjusted) return is +25947.5%.

Lump sum instead — $50,800 all at once in May 1984: $86,433,171 (+170044.0%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Jun 2026): $286.55 on $300 invested (-4.5%).

⚠ 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.
