Scenarios
Inflation — the same contributions merely keeping pace with CPI would be $90,910 today, so the real (inflation-adjusted) return is +883.6%.
Lump sum instead — $50,000 all at once in Jan 1985: $3,050,269 (+6000.5%) — lump sum came out ahead.
Worst timing — same monthly amount started at the all-time high (May 2025): $1,610 on $1,600 invested (+0.6%).
⚠ 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.
