May 30, 2026, 2:32 AM EDT. Passive income from a Stocks and Shares ISA is often linked to large initial investments, but consistency also plays a key role. A model starting with a £40,000 lump sum and increasing yearly contributions hitting £7,700 by year 20 shows that while early capital compounds faster, ongoing contributions increasingly drive wealth growth. Using a 4% return assumption, wealth creation shifts over 20 years from initial capital dominance to steady investments. The main takeaway: passive income isn't exclusive to wealthy investors. Time, regular investing, and compounding power combined build substantial returns. This gradual wealth accumulation aligns with steady, subscription-based businesses like RELX (LSE: REL), known for recurring revenues and stable customer bases.
