How Much Could £20k in a Stocks and Shares ISA Be Worth by 2030?

Investing in a Stocks and Shares ISA has delivered strong returns for UK investors over the past five years. But what could the next five years bring? With a £20,000 annual ISA allowance, savvy investors have a powerful tax-free tool for wealth building.

Projected Returns for a £20k Stocks and Shares ISA

Historical market performance gives us a rough estimate of potential ISA growth:

• FTSE 100 average return (20 years): 6.3% p.a.

• S&P 500 average return (long-term): ~10.5% p.a.

A well-diversified portfolio could realistically achieve 8% annual growth. Based on this, £20,000 invested today could grow to £29,796 in five years—a £9,796 tax-free profit.

However, stock selection is crucial. Poor choices could lead to lower returns, while high-growth stocks could outperform.

How to Pick Winning Stocks for Your ISA

To maximise long-term ISA growth, consider these key metrics:
✔ Revenue growth rate – Consistent sales expansion indicates strong demand.
✔ Return on Equity (ROE) – Measures profitability relative to shareholder equity.
✔ Earnings Per Share (EPS) growth – Shows a company’s profit growth over time.

Stocks excelling in these areas tend to deliver sustained growth.
