Scenarios

Inflation — the same contributions merely keeping pace with CPI would be £73,265 today, so the real (inflation-adjusted) return is +243.6%.

Lump sum instead — £42,100 all at once in Jun 1988: £829,185 (+1869.6%) — lump sum came out ahead.

Worst timing — same monthly amount started at the all-time high (Apr 2026): £481.8 on £500 invested (-3.6%).

⚠ 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.
