Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $90,910 today, so the real (inflation-adjusted) return is +2329.8%.

Lump sum instead — $50,000 all at once in Jan 1985: $28,921,471 (+57742.9%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (May 2025): $1,697 on $1,600 invested (+6.1%).

⚠ 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.
