Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $50,259 today, so the real (inflation-adjusted) return is +258.7%.

Lump sum instead — $33,800 all at once in Jul 1998: $958,977 (+2737.2%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Mar 2024): $1,551 on $3,000 invested (-48.3%).

⚠ 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.
