Scenarios

Inflation — the same contributions merely keeping pace with CPI would be $23,313 today, so the real (inflation-adjusted) return is +433.9%.

Lump sum instead — $18,300 all at once in Jun 2011: $307,873 (+1582.4%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Jul 2026): $210.04 on $200 invested (+5.0%).

⚠ 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.
