A Stocks and Shares ISA is a powerful tool for building long-term wealth and generating passive income. With tax-free gains and dividends, it provides an efficient way to grow investments without losing returns to HMRC.
Over time, compound growth can significantly enhance wealth, making ISAs ideal for those seeking financial security. Whether investing in dividend stocks for passive income or growth shares for capital appreciation, the ISA’s tax advantages and flexibility make it an essential component of any UK investor’s portfolio. So, let’s put a figure on it. In order to receive around £5,000 in monthly passive income from an ISA, I believe an investor would need around £1.2m in the ISA pot.

Here’s the formula
Building a £1.2m ISA pot from scratch takes time, patience, and regular investing. The key is consistency and the power of compound growth. With a fixed amount invested each month, returns start generating returns of their own, accelerating wealth accumulation. For instance, assuming a 7% annual return, investing £1,000 per month for 30 years could grow to around £1.2m. Increasing contributions or extending the timeline further boosts the chances of hitting the target. The earlier investing begins, the less heavy lifting is needed later to achieve financial independence.
Moreover, more successful investors can reach their targets faster and typically with less capital. For instance, £500 of monthly contributions for 30 years growing at a compound annual growth rate (CAGR) of 10.5% would also reach £1.2m.
Another important thing to note is the impact of compound interest. As the investment grows, the rate of growth appears to increase too. In the 30th year, the investment would grow by £124k versus £297 in the first year.
Finding diversity
As someone with a relatively mature portfolio, I prefer to pick my own stocks. I have around 25, meaning my portfolio is relatively diversified. But if I were starting afresh I’d look to achieve some diversification by investing in exchange-traded funds (ETFs) or trusts.
With that in mind, investors may want to consider The Monks Investment Trust (LSE:MNKS), which offers a compelling opportunity for long-term capital growth through its diverse global equity portfolio. The trust’s holdings include tech giants like Microsoft, Meta Platforms, and Amazon, alongside innovative companies such as Nvidia and Prosus. This mix of established and growth-oriented firms across various sectors provides a balanced approach to global investing.
With a significant portion invested in the US and smaller allocations in countries like the Netherlands, Japan, and China, Monks also offers broad geographical exposure. The trust’s relatively low ongoing charge of 0.44% makes it an attractive option for cost-conscious investors seeking actively managed global equities.
Moreover, its patient investment strategy, focusing on companies with enduring competitive advantages, aligns well with those looking for sustained value creation. The trust’s long-standing history since 1929 further underscores its resilience through various market cycles.
But while diverisification offers us protection against some risks, investors should note that some of its largest holdings, including Meta and Amazon, have fairly lofty valuations. This may put some investors off.
However, it’s a stock I’ve bought for my daughter’s SIPP.
